When manually activating an eSIM, the process can be more detailed than the automatic activation. Upon turning on your cellphone, the eSIM might automatically activate and complete its installation. However, if you choose manual activation, such as during the initial setup of an iPhone, you can use options like eSIM Carrier Activation or eSIM Quick Transfer. These options allow the operator to assign an eSIM to your phone right from purchase, which can then be activated during the initial setup of the device.

If automatic options are not available or you prefer a more hands-on approach, manual activation through a QR code or the carrier’s official app is the alternative. This method involves scanning a QR code provided by your carrier or following specific instructions within the app to activate your eSIM. If you encounter any challenges during this process, it’s advisable to contact your carrier directly for assistance or a step-by-step guide to ensure the eSIM is activated properly and ready for use. This direct communication can provide tailored support for your specific device and eSIM.

The eSIM Signal Issues

If your eSIM card lacks signal, the most likely issue is inadequate network coverage from your operator in your current location. This is particularly relevant for international travel, where coverage can vary significantly. Before traveling, verify with your operator if they provide coverage in your destination. Additionally, check for any service limitations due to billing or account issues, as these can sometimes restrict network access. Ensuring all aspects related to coverage and account status are clear can help diagnose signal issues with your eSIM.

Other possible reasons for eSIM card not working

  1. Activating eSIM on a New Device: Before activating an eSIM on a different device, check for eSIM compatibility and whether the device is carrier-unlocked. The device must be able to support your operator’s network standards for the eSIM to function correctly.
  2. Device Reported as Lost/Stolen: If a device is reported lost or stolen, it is typically barred from network services, including eSIM installation and activation.
  3. Accidental Deletion of eSIM: If you accidentally remove your eSIM, contact your service provider’s customer support for guidance. If your eSIM is associated with a traditional telecom provider, you may need to log in to your mobile account online and select the option to obtain a new eSIM.
  4. Network Coverage and Service Limitations: Ensure your area has strong network coverage from your eSIM provider. If you’re experiencing slow data speeds, it might be due to limitations in network services in your location. Contacting your service provider for support can help resolve these issues.
  5. Activation Problems: If the eSIM does not automatically activate after purchase, you may need to reach out to your carrier’s technical support for an activation QR code or specific guidance.
  6. Improper APN Settings: The Access Point Name (APN) settings should be correctly configured for your eSIM to work. Some operators restrict APN configuration to specific circumstances, like connecting to international networks. If you can’t find the option to configure the APN, it might be restricted by your carrier for security reasons.
  7. Transferring eSIM to a Different Device: To transfer an eSIM to another device, both devices need to be eSIM compatible. For eSIMs linked to a mobile carrier, you usually can manage the transfer through the carrier’s website, under sections like ‘Transfer eSIM’ or ‘Change Device’. Having your new device’s IMEI number at hand is essential for this process.
