Activate Your eSIM Instantly With These Simple Step by Step Instructions

Imagine you land in a new country and need data instantly—activating an eSIM lets you skip the plastic card hunt. You simply scan a QR code from your provider or enter a manual code in your phone’s settings to download a digital SIM profile directly. This process links your device to a cellular network in minutes, freeing you to switch plans or carriers without swapping physical cards. Benefits include dual-line usage for work and personal numbers on one device, all managed from your phone’s menu.

Understanding eSIM Technology

Understanding eSIM technology means knowing it’s a tiny, embedded chip replacing your physical SIM card. To activate an eSIM, you don’t insert anything; instead, you scan a QR code from your carrier or download their app. Your phone’s settings menu has a dedicated ‘Add eSIM’ option where you enter this code manually if scanning fails. The system downloads a digital profile instantly, authenticating your number on the network. Unlike plastic SIMs, eSIMs let you switch carriers by simply deleting the old profile and adding a new one—no waiting for a card to arrive. Just ensure your device is unlocked and connected to Wi-Fi during the setup.

What distinguishes an eSIM from a physical SIM card

An eSIM is a programmable chip embedded in your device, unlike a physical SIM card which is a removable plastic card. During activation, you download a carrier profile instead of inserting a physical card. This means you can switch carriers or plans without waiting for a new SIM to arrive. To activate an eSIM, the sequence is typically:

1. Obtain a digital carrier profile via a QR code or app.
2. Scan or install it in your device’s settings.
3. Select the new eSIM line for use.

You can also store multiple profiles on one device, whereas a physical SIM slot holds only one card at a time.

Which devices support embedded SIM profiles

Support for embedded SIM profiles is not universal, requiring specific hardware. Most recent flagship smartphones from Apple, Google, and Samsung include this capability. For activation, a device must have an embedded SIM chip that can be rewritten with carrier eSIM activation data. Older models or region-specific variants may lack this feature despite similar branding. Key compatible categories include:

• iPhone XS and newer (excluding some China models)
• Google Pixel 3 and later (excluding Pixel 3 in certain regions)
• Samsung Galaxy S20 series and newer, plus Z Fold/Flip series

Advantages of switching to a digital SIM

Switching to a digital SIM offers key practical benefits during activation. You eliminate the need to wait for a physical card, as the profile downloads directly to your device. This allows for instant carrier switching without swapping trays. Managing multiple lines becomes simpler, as you can store several profiles and activate one per your needs. The risk of losing or damaging a tiny physical SIM is removed.

• Immediate activation without waiting for postal delivery
• Effortless provisioning of a second line for travel or work
• No physical card to misplace or damage

Preparing Your Device for Activation

Before activating your eSIM, ensure your device is unlocked and compatible by checking the manufacturer’s IMEI or settings menu. Update your phone to the latest OS version to avoid activation failures, as outdated software often blocks the process. Connect to a stable Wi-Fi network; cellular activation requires internet access to download the eSIM profile. Remove any physical SIM cards if you plan to use the eSIM as your primary line. Surprisingly, having low device storage can also interrupt profile installation. Confirm your device supports dual SIM functionality if you intend to keep both lines active. Finally, locate your network provider’s QR code or activation details before starting.

Checking compatibility with your carrier

Before beginning eSIM activation, contact your carrier directly to confirm it supports eSIM technology for your specific device model and plan. Verify that your account is eligible for eSIM provisioning, as some prepaid or business lines may require a plan change. Ask the carrier to confirm that your device is not carrier-locked to another network, which would block activation. Request specific instructions, as some carriers may require a QR code or activation code sent via email or in-app. Performing this check first prevents wasted time attempting to activate on an incompatible carrier.

Ensuring your phone runs updated software

Before initiating an eSIM activation, updating your device’s operating system is non-negotiable. Carrier profiles and digital SIM provisioning rely on the latest security patches and firmware. An outdated OS can block the installation prompt or fail to recognize the eSIM configuration. Navigate to Settings, then System Update, and install any pending software. This eliminates common error codes during activation and ensures your phone has the necessary baseband drivers. Perform this step first to avoid a failed setup, forcing you to contact support for a new QR code or confirmation token.

Backing up contacts and critical data

Before you yank your old physical SIM, back up your contacts and critical data to the cloud or your computer. An eSIM activation can sometimes reset network settings or require a factory reset if issues arise, so you don’t want to lose that info. Think of this as a safety net for your phone number and text history. Use your phone’s built-in sync tool (like iCloud or Google) or export a .vcf file directly. Double-check that photos, passwords, and notes are also saved elsewhere. This way, if the activation glitches, your essential data stays safe and restorable.

Acquiring an eSIM from Your Provider

To activate an eSIM, you must first acquire it directly from your carrier, typically via their website or app after logging into your account. Select a compatible data plan, and the provider will issue a QR code or digital activation file—often within minutes.

This code is your sole key to installation; save it securely, as some carriers only offer it once.

You then access your device’s cellular settings, scan the QR code or download the profile, and follow on-screen prompts to finalize activation. Ensure your phone is unlocked and Wi-Fi-connected during the process to avoid interruptions.

Requesting a QR code or activation code

To acquire your eSIM, you must specifically request a QR code or activation code from your provider during the purchase or plan change process. This code is typically delivered via email or your provider’s app immediately after payment confirmation; it contains all data necessary to download the eSIM profile. Do not delete or screenshot the email, as the code often expires after a single use or within a set timeframe. If you do not receive it within minutes, check your spam folder or contact support directly, referencing the order number.

Q: What if I lose my QR code or activation code before scanning it?
A: Contact your provider’s support team to request a new code. Most providers can regenerate a fresh QR code for you, though some may charge a small administrative fee. Do not attempt to reuse an expired or previously scanned code, as it will fail to activate your eSIM.

Downloading the carrier’s dedicated app

To begin activation, locate your carrier’s dedicated app in the official app store. Downloading the carrier’s dedicated app is often the preferred method, as it automates the eSIM provisioning process and eliminates the need for scanning a physical QR code. After installation, log in using your account credentials, then navigate to the eSIM or “Get a New Line” section. The app typically retrieves your device’s compatibility and presents a plan selection. Follow the on-screen prompts; the app will remotely install the eSIM profile and configure the cellular plan automatically. This app-based method ensures a streamlined activation with immediate network connectivity.

Q: Is downloading the carrier’s dedicated app mandatory to acquire an eSIM?
A: Not always. While many carriers offer this for a simplified activation, you can often receive a QR code via email or web portal. However, the app remains the most straightforward route if your carrier supports it.

Purchasing a plan via the provider’s website

Purchasing a plan via the provider’s website begins by logging into your account and navigating to the eSIM section. Select a data or voice plan compatible with your device, then proceed to checkout. After payment, the provider typically displays a QR code for immediate eSIM activation or sends it to your email. To ensure installation, follow this sequence:

1. Access your device’s mobile network settings and choose “Add eSIM.”
2. Scan the QR code displayed on your monitor or from the emailed attachment.
3. Label the new line (e.g., “Travel Data”) and set default numbers for calls and messages if prompted.
4. Confirm activation by checking for cellular signal and service confirmation in your settings.

Setting Up the eSIM on iPhone

To set up eSIM on iPhone, begin by purchasing a compatible eSIM plan from your carrier. For activation, go to **Settings** > **Cellular** > **Add Cellular Plan**. Scan the QR code provided by your carrier or manually enter the details. If your carrier supports Quick Transfer, you can move an eSIM directly from your old iPhone. Follow on-screen prompts to confirm your plan, then label it (e.g., Primary or Business). Finally, set your default line for calls and data. This process lets you activate eSIM instantly, avoiding physical SIM cards, and enables seamless dual-line functionality on supported iPhone models.

Navigating to Cellular settings

To get your eSIM going, you’ll need to first find the right spot on your phone. Start by opening the Settings app, then tap “Cellular” or “Mobile Data.” On an iPhone, this is where all your network toggles live. If you see an option like “Add Cellular Plan” or “Add eSIM,” you’re in the right place. Don’t worry if it looks different on older iOS versions—just look for anything about cellular or mobile networks. Once you’re there, follow the on-screen prompts to scan your QR code or enter details manually.

Q: What if I can’t find “Cellular” in my iPhone Settings?
A: That’s odd but possible—try searching “Cellular” in the Settings search bar at the top. If it still doesn’t show, your device might be Wi-Fi only, or you’re in a region where the label says “Mobile Data” instead.

Scanning the QR code from your carrier

If your carrier provides a QR code for your eSIM, scanning it is usually the fastest route. In your iPhone’s Settings, go to Cellular, then tap “Add Cellular Plan.” Point your camera at the carrier-provided QR code and wait for the prompt. After it’s scanned, your eSIM details load instantly, and you’ll label the plan (e.g., “Work” or “Travel”) before activating it.

What if the QR code won’t scan? Make sure your camera lens is clean and the code isn’t damaged. You can also try manually entering the details under “Enter Details Manually” if scanning fails due to poor lighting or reflection.

Manually entering activation details

If your carrier does not provide a QR code, you can activate eSIM by manually entering activation details. In your iPhone’s Settings, go to Cellular, then “Add Cellular Plan.” Select “Enter Details Manually” and input the SM-DP+ address and activation code provided by your carrier. After entering the information, confirm and follow on-screen prompts. The accuracy of these details is critical; a single typo can prevent successful activation. What if my iPhone says “Invalid Activation Code” during manual entry? Double-check the SM-DP+ and code for typos, as these codes are case-sensitive and carrier-specific.

Labeling and customizing your new line

After activating your eSIM, immediately assign a unique label to distinguish it from your primary line. Tap “Mobile Data” or “Cellular” in Settings, select your new plan, and choose “Mobile Plan Label.” Pick a custom name like “Business,” “Travel,” or “Work” from the list, or create your own by tapping “Custom Label.” This helps you quickly identify which line is active for calls, messages, and data. You can also set your preferred default line for China eSIM contacts and iMessage, ensuring seamless daily use without confusion.

Customizing your eSIM label instantly clarifies which line handles calls and data, turning confusion into control.

Activating eSIM on Android Devices

To activate an eSIM on an Android device, start by ensuring your phone is unlocked and connected to Wi-Fi. Navigate to **Settings > Connections > SIM card manager**, then tap “Add mobile plan.” You’ll scan a QR code provided by your carrier or manually enter the activation details. Does activating an eSIM on Android remove your physical SIM? No, it runs alongside it, letting you switch between lines for data and calls instantly. After scanning, confirm the plan and reboot your device; your eSIM profile will appear as a secondary line, ready to use.

Accessing Network and Internet settings

To begin eSIM activation, open your device’s **Settings** app and tap “Network & Internet” or “Connections.” Select “SIMs” or “SIM card manager,” then choose “Add mobile plan.” Your phone will scan for available networks; if no plan appears, select “Scan QR code” or “Enter details manually,” which the carrier provided. Ensure Wi-Fi or mobile data is active during this setup, as the activation process requires a connection. Within this menu, you can also toggle the new eSIM line on or off and set it for data, calls, or SMS.

Accessing Network & Internet settings is the dedicated path to add, scan, or manually enter an eSIM profile from your carrier.

Adding a mobile plan via QR scan

Adding a mobile plan via QR scan is a primary eSIM activation method. After accessing the “Add mobile plan” or similar option in Android’s Network & Internet settings, you select “Use a QR code.” The device’s camera activates; positioning the QR code from your carrier within the viewfinder triggers automatic detection. The device then downloads and installs the profile, often prompting you to name the line. This avoids manual entry of long activation codes. QR scan activation is typically the fastest method, as it directly encodes the SM-DP+ address and confirmation code needed to provision the eSIM.

Q: What if the QR code scan fails repeatedly? A: Failed scans often result from poor lighting, a damaged QR code image, or camera obstruction. Clean the camera lens, ensure the full QR pattern is visible and steady, or try manually entering the code provided by your carrier under the “Enter details manually” option.

Using the carrier’s app for automatic setup

For the quickest activation, using the carrier’s app for automatic setup is your most efficient option. First, download your specific carrier’s official app from the Play Store and log in to your account. Navigate to the eSIM activation section, where the app will automatically detect your compatible Android device. You simply confirm your plan selection, and the app remotely installs the eSIM profile. This method eliminates manual QR code scanning or entering long activation codes, making seamless eSIM installation effortless. Within moments, your device connects to the network, allowing you to activate service without visiting a store or handling physical cards.

Choosing default SIM for calls and data

Once your eSIM is activated, you must designate which SIM handles specific functions. Navigate to your device’s SIM manager in Settings to set default eSIM for data and calls. Assign the eSIM for mobile data by selecting it under the preferred SIM for data, ensuring you choose the line with your active data plan. For voice calls, you can set the eSIM as the default for all calls or choose to ask each time. Separately, you may keep your physical SIM for SMS. These selections are critical to avoid unexpected charges and ensure your eSIM is the active line for connectivity.

Alternative Activation Methods

When your eSIM doesn’t activate automatically, you can use alternative activation methods like scanning a QR code emailed by your carrier or manually entering the SM-DP+ address and activation code. For a quicker fix, many providers now offer app-based activation, where you install their app and tap “Add eSIM” to pull the profile directly. If QR scanning fails, manual input in your phone’s settings under Cellular or Mobile Data works—type the long activation code exactly as provided. Some carriers also let you paste a profile URL from their website. Always ensure Wi-Fi is on during setup to download the eSIM profile.

Enabling eSIM without a QR code using a PUK

When a QR code is unavailable, enabling an eSIM via a PUK code offers a reliable fallback. This method requires entering an eight-digit PUK, typically provided by your carrier separately from the QR. You manually input this code in your device’s cellular settings, often under the option to add a mobile plan. Once entered, the PUK unlocks and installs the eSIM profile directly. This approach is essential for users who misplaced the original QR or whose carrier exclusively supports PUK-based provisioning. Always store the PUK securely, as repeated incorrect entries can permanently lock the eSIM. This makes PUK-based eSIM activation a precise tool for controlled deployment.

Switching from physical SIM to eSIM in settings

For users with an active physical SIM, switching to an eSIM is often handled directly within the device settings. Navigate to the mobile network or cellular section and select the option to convert your current plan. This process typically transfers your existing number and service to the embedded digital SIM profile without requiring a new QR code from your carrier. After confirming the conversion, the phone deactivates the physical SIM slot and activates the eSIM line internally. Keep your physical SIM card safe afterward, as it becomes inactive and should be removed from the device to avoid conflicts.

Activating during initial device setup

During initial device setup, many modern smartphones prompt users to activate an eSIM as part of the out-of-box experience. This method typically involves scanning a QR code provided by the carrier or selecting a plan from a pre-installed list of compatible carriers. Activating during initial device setup simplifies the process by integrating eSIM configuration into the first-time configuration wizard, allowing you to skip a physical SIM slot entirely. Once the eSIM profile is downloaded, data and calling features become available immediately without additional steps.

• Scan the carrier’s QR code when the setup assistant requests a cellular plan.
• If prompted, confirm the plan on the carrier’s website or app before proceeding.
• Ensure a stable Wi-Fi connection is available for downloading the eSIM profile during setup.

Troubleshooting Common Activation Issues

When activating eSIM, a common issue is a “No Service” error after scanning the QR code. Ensure your device is connected to a stable Wi-Fi network during the entire process, as cellular data is often unavailable until activation completes. If the activation fails, check that your phone isn’t carrier-locked and that you haven’t accidentally deleted the eSIM profile before it was fully provisioned. Force restarting your device often resolves stuck activation loops. Finally, verify that your mobile plan’s data and APN settings are correctly entered—particularly for custom carrier profiles—as mismatched configurations directly prevent eSIM setup from finalizing.

QR code not scanning properly

A QR code may fail to scan during eSIM activation due to physical damage, screen glare, or improper camera focus. To resolve this, first ensure the QR code is not distorted or scratched and that the device’s camera lens is clean. If the code appears on another screen, maximize brightness and reduce reflections. For persistent failures, follow this sequence:

1. Request a manual activation code from your carrier as a backup.
2. Use a secondary device to display the QR code while scanning with your eSIM-capable phone.
3. Restart the phone to clear temporary camera or network glitches.

If scanning still fails, confirm the QR code was issued specifically for your eSIM profile, as reuse of an expired code is a common cause.

No service after profile installation

If you see “No Service” after your eSIM profile installation, the issue usually lies with incomplete activation or network registration. First, ensure your device’s eSIM activation process fully completed by checking that the profile appears under your mobile network settings. Common fixes include toggling Airplane Mode for 30 seconds to force a re-registration, or manually selecting your carrier’s network. If the profile is correctly installed but service remains absent, confirm your plan is active with your carrier, as provisioning can take several minutes.

• Verify the eSIM profile is selected as the active line for data or calls.
• Reboot your device to trigger a fresh network attach procedure.
• Ensure your device is unlocked and supports your carrier’s specific eSIM frequency bands.
• Contact your carrier to confirm the eSIM is provisioned and associated with your IMEI.

eSIM profile missing from device menu

If the eSIM profile missing from device menu after scanning a QR code, first restart your phone to force a carrier refresh. Navigate to Settings > Cellular/Mobile Data and tap “Add eSIM” manually. If the profile still doesn’t appear, verify your device isn’t carrier-locked, which blocks foreign eSIMs. Even a partially downloaded profile can hide until you delete and re-scan the QR code.

• Ensure your device runs the latest OS version, as old firmware can hide the eSIM slot.
• Reset network settings to clear cached data that might block profile visibility.
• Contact your carrier to confirm the eSIM hasn’t expired or been assigned to another IMEI.

Contacting support for persistent errors

If standard troubleshooting fails to resolve a persistent activation error, contact your carrier’s dedicated eSIM support. Provide the specific error code, your device model, and the steps already attempted. Direct carrier support for eSIM can remotely verify your profile provisioning status or issue a new QR code. Avoid retrying activation indefinitely—this may trigger a temporary lock. The support agent may push a reset command to your device’s eSIM module through the carrier backend.

Contacting support is the necessary step when self-service fixes fail; supply error details and device info for remote provisioning correction.

Managing Multiple eSIM Profiles

Managing multiple eSIM profiles is straightforward once you know how to activate eSIM. Most devices let you store several plans, but you can only use one at a time. After activating a new profile via scanning or app download, simply label each one clearly (e.g., “Work” or “Travel”) to avoid confusion. Switching between them is done in your settings menu under cellular or mobile data. Q: Can I have two active lines simultaneously? A: Yes, if your phone supports Dual SIM—just activate one eSIM for data and keep another for calls, but only one profile can be active per network slot at any moment. Always keep your primary profile details saved before activating a new one to prevent accidental deletion.

Storing several plans on one phone

Storing several plans on one phone is a core advantage of eSIM technology, allowing you to manage multiple mobile profiles without physical SIM swaps. After activating your first eSIM, you can immediately add further plans from different carriers through the same device settings. This enables you to keep a local data plan for travel alongside your home number, for example. Managing multiple eSIM profiles becomes a seamless process of toggling between active lines for calls and data.

• Install additional eSIMs directly via carrier apps or QR codes.
• Switch voice or data lines without removing a physical SIM.
• Store up to 8 or more eSIMs, though only two can be active at once.

Switching between work and personal lines

Switching between work and personal lines on a single eSIM becomes effortless once both profiles are activated. After you’ve set up each line, typically by scanning separate QR codes or installing carrier apps, your device’s settings menu governs all changes. Use the **cellular or mobile data options** to designate a primary line for voice, messaging, or data, with the secondary line automatically suspending when not in use. Toggle each profile instantly via a dedicated button—no physical SIM swap required—ensuring you disconnect from office calls after hours without removing any carrier details.

How do I quickly switch between my work and personal eSIM lines? Open your phone’s settings, choose the cellular section, and simply select which line to enable as active for calls and data. The other line remains dormant but intact, ready to reactivate in one tap.

Removing or disabling an unused profile

Once you’ve activated a new eSIM, managing clutter from old ones is essential. To remove an eSIM profile, navigate to your device’s mobile network settings, select the unused profile, and tap “Delete” or “Remove Cellular Plan.” Disabling, without deleting, is ideal for temporary deactivation: simply toggle the line off in the same menu. This keeps the profile intact for quick reactivation, perfect when traveling or testing carriers. For a clear sequence, follow these steps:

1. Open Settings > Cellular (iOS) or Network & Internet (Android).
2. Choose the unused profile under eSIM or SIM cards.
3. Tap “Remove Cellular Plan” for permanent deletion, or toggle the switch off to disable.

Clean management prevents accidental data charges and simplifies future activation.

Post-Activation Configuration Tips

Once your eSIM activation kicks off, you’ll want to check your post-activation configuration tips to avoid hiccups. First, hop into your phone’s cellular settings and label each line clearly (like “Work” or “Travel”) if you have multiple plans. Then, set your preferred default line for voice and data—this is a crucial how to activate eSIM follow-up step. Turn your data roaming on if you’re traveling, and run a test call or text to confirm everything routes correctly. If you see “No Service,” try toggling the eSIM line off and on again. Reboot your device if needed, and you’re good to go.

Setting the primary data line

Once your eSIM is activated, setting the primary data line ensures your new plan handles all internet traffic. Navigate to your phone’s cellular settings, locate the list of active plans, and tap the one you intend for data. Selecting it as the default line immediately shifts connectivity to the eSIM while keeping your physical SIM for calls. This single toggle prevents accidental roaming charges on your other line and clarifies which number apps like iMessage use. Confirm the selection by observing the carrier signal indicator update, verifying that your eSIM is now the active gateway for all online activity.

Configuring iMessage and FaceTime for new eSIM

Once your new eSIM is active, you’ll want to get iMessage and FaceTime working smoothly. Start by heading to **Settings > Messages** and toggling iMessage off, then back on. This forces your phone to re-register your new eSIM’s number. Do the same in **Settings > FaceTime**. Next, check that “Send & Receive” under Messages lists your new number, and set it as your default. If texts still go to your old line, a quick restart often seals the deal. Follow these simple steps:

1. Go to **Settings > Messages**, toggle iMessage off, then on.
2. In **Settings > FaceTime**, toggle it off and back on.
3. Verify your new eSIM number appears under “Send & Receive.”
4. Restart your iPhone to lock in the eSIM iMessage activation.

Testing call and data functionality

After eSIM activation, testing call and data functionality immediately confirms the setup is correct. First, place a test call to a voicemail or a friend to verify voice works. Then, open a web browser or stream a short video to check mobile data. For a clear sequence, follow these steps:

1. Disable Wi-Fi to force data over the eSIM network.
2. Send a text message to a different carrier to confirm SMS/MMS routing.
3. Toggle Airplane Mode off and on, then re-run a speed test to ensure stability.

If calls drop or no data appears, restart the device and re-check the APN settings. Immediate verification prevents service surprises later.

Securing the eSIM with a device passcode

After eSIM activation, immediately securing the eSIM with a device passcode is a critical step, as the passcode encrypts the entire device, including the eSIM profile. When you enable a strong device passcode, anyone who gains physical access to your phone cannot remove, disable, or transfer your eSIM without unlocking the device first. This prevents unauthorized individuals from using your mobile plan on another device or swapping your eSIM data. In iOS, the Face ID or Touch ID paired with a passcode also blocks direct access to the eSIM deletion menu. For Android, ensure SIM lock settings require the passcode for any eSIM management.

• Set a six-digit or alphanumeric passcode instead of a simple four-digit code for stronger encryption of the eSIM data.
• Activate biometric authentication (fingerprint or face recognition) as a second layer to block eSIM removal in system settings.
• Verify that the passcode is required immediately after device sleep, not after a delay, to close exposure windows.

Frequently Encountered Pitfalls to Avoid

Skipping compatibility checks is a primary pitfall; ensure your device is carrier-unlocked and explicitly supports eSIM, not just dual-SIM. Scanning the QR code from a screenshot rather than the original email often fails due to resolution loss, so always use the source image. A critical mistake is initiating activation while on a poor Wi-Fi or cellular connection, as the download may timeout and corrupt the profile. Users frequently overlook that removing the physical SIM before the eSIM is fully activated can disrupt the provisioning sequence. Finally, failing to enter the activation code manually when the QR scan fails is a common, avoidable error.

Erasing the QR code before backup

One major pitfall is erasing the QR code before backup. That QR code is your one-way ticket to activating your eSIM, so once you delete the email or screenshot, you’re stuck if you ever need to reinstall the profile. Always save a copy—either in your phone’s notes app or a secure cloud folder—before you swipe it away. Then, once the eSIM is confirmed working, you can safely erase it.

• Take a screenshot of the QR code and store it in a password-protected folder
• Forward the activation email to yourself as a backup
• Wait until the eSIM shows “active” in settings before deleting the image

Activating eSIM outside your home region

A frequent mistake is attempting to activate eSIM outside your home region, which often fails because the carrier’s network registration servers are geo-locked. Activation requires your phone to connect to a local tower from your home country first. If you try this abroad, the eSIM profile may download but refuse to register, leaving you with no service. To avoid this, install the eSIM before you depart, while your device is on its home network. If you are already overseas, locate a Wi-Fi hotspot and contact your carrier—they can sometimes provision the profile manually from their end.

Question: What should I do if I already activated eSIM outside my home region and it won’t connect?
Answer: Toggle Airplane Mode for 60 seconds, then manually search for a network in your cellular settings. If that fails, connect to Wi-Fi and ask your carrier to whitelist the eSIM IMEI from their side.

Forgetting to disable the old physical SIM

A critical mistake during eSIM activation is forgetting to disable the old physical SIM. If both SIMs remain active, the device often defaults to the physical card for cellular data, defeating the purpose of the eSIM switch. This conflict can cause registration failures on the network or prevent the eSIM profile from downloading correctly. After inserting the eSIM, immediately navigate to your SIM manager and deactivate the physical slot. Only then will the device properly prioritize the new digital line, ensuring seamless provisioning and avoiding unexpected roaming charges from the dormant card.
