¿Por qué mi eSIM no funciona? Guía de solución de problemas de eSIM

Checking Compatibility

  1. Before diving into troubleshooting, it's crucial to ensure that your device is compatible with eSIM technology. Not all phones support eSIMs, so your first step should be to check your phone's compatibility. Visit eSIM Compatible devices to find a comprehensive list of devices that support eSIM. This resource will provide you with up-to-date information on various phone models across different operating systems, helping you verify if your device can use eSIM.
  2. The "*#06#" Code: This code displays your IMEI (International Mobile Equipment Identity). Some phones might also show an EID (Embedded Identification Document) number if an eSIM is present. However, the lack of an EID doesn't guarantee that your phone doesn't support eSIM.

Understanding eSIM Internet Connection Problems

Despite your eSIM appearing connected, you might face difficulties such as extremely slow download/upload speeds, the persistent appearance of "E" (Edge) instead of 4G/LTE, or a complete lack of internet connection.

These issues can stem from various factors, which we will address along with solutions to ensure you can efficiently resolve them.

Troubleshooting Steps

Before You Start: Preserve Your eSIM

IMPORTANT: Do not delete the eSIM from your phone. If you encounter issues, follow the steps below or contact support for assistance: admin@esimfox.com

1. Verify eSIM Service Area

Service Area Limitation: Ensure you're within the service area of your eSIM. For instance, an eSIM purchased for France will only operate within France. Installation is possible anywhere, but connectivity is region-specific.

2. To Fix iPhone eSIM Not Working:

  • Ensure Strong Coverage: Before proceeding, make sure your device has a strong network signal. Weak coverage can often be the root cause of eSIM problems.
  • Reboot Your Device: A simple reboot can refresh the system and resolve temporary glitches. To do this, power off your device and then turn it back on.
  • Check Mobile Data Settings: Go to “Settings > Mobile/Cellular Data.” Here, verify that your eSIM settings are correctly configured.
  • Enable Data Roaming When Abroad: If you’re traveling, activate data roaming to maintain eSIM connectivity. This is found under “Settings > Mobile/Cellular Data > Mobile/Cellular Data Options > Data Roaming.”

  • Network Settings Reset: If the problem persists, reset your network settings. This is done via “Settings > General > Transfer or Reset Device > Reset > Reset Network Settings.” Remember, this will also erase saved Wi-Fi networks, VPN settings, and APN settings.


3. To Fix Android eSIM Not Working:

  • APN Configuration: Navigate to Settings > Mobile & Network > eSIM plan > Access Point Names. Add a new APN with the name "plus" and ensure no username or password is set. Select this APN.
  • Check for Adequate Signal: As with iOS, start by ensuring your Android device has good network coverage.
  • Reboot Your Device: Power off and then turn your device back on to reset the system.
  • Toggle Cellular Data: Sometimes deactivating and reactivating cellular data can help. Navigate to “Settings > Mobile/Cellular Data Network > Mobile/Cellular Data” to do this.
  • Reset Network Settings: If the issue isn’t resolved, reset your network settings. On Android, go to “Settings > General > Reset Network Settings > Reset Settings.” This step, like with iOS, will also reset your Wi-Fi and other network-related settings.

4. Reset Data Connection

Airplane Mode Trick: Enable Airplane Mode for 30 seconds, then disable it. This forces a network reconnect. Allow up to 15 minutes for the eSIM to authenticate and start receiving data.

5. Manually Select a Network

For Apple iOS (iPhone): Go to Settings > Cellular > eSIM plan > Network Selection. Disable "Automatic" and manually select an available network. After connecting, revert the selection to "Automatic."

If manual network selection is needed, contacting support can guide you to the most suitable network.

Additional Solutions

Still No Connection?

  • Submit a Support Request: If issues persist after following the above steps, reach out for further assistance.
  • Consider External Factors: Sometimes, no service areas or network issues beyond control can affect connectivity. Setting the Network Selection to "Automatic" allows your device to keep searching for a signal.

Additional Considerations for eSIM Functionality

Device Status: Reported as Lost or Stolen

Devices reported as lost or stolen are typically restricted from accessing network services. This restriction extends to eSIM installation and activation. If your device is under this category, resolving the issue with your service provider is necessary before eSIM functionality can be restored.

Accidental Deletion of eSIM

In the event of an accidental eSIM deletion, immediate contact with your service provider’s customer support is advisable. Depending on whether your eSIM is from a traditional telecom provider, you might need to access your mobile account online and follow the procedure to acquire a new eSIM.

Network Coverage and Service Limitations

Strong network coverage is paramount for eSIM functionality. If you're experiencing inadequate data speeds, it could be attributed to network service limitations in your area. Engaging your service provider can offer insights and solutions to these challenges.

Transferring eSIM Between Devices

Transferring an eSIM to a different device requires that both devices support eSIM technology. For mobile carriers, this process is often manageable through the carrier’s website, typically under options like ‘Transfer eSIM’ or ‘Change Device’. It’s important to have the IMEI number of your new device ready for this procedure.
