The eSIM does not connect to the internet
Make sure you are located within the eSIM's designated coverage area.
Remember, the eSIM will only connect to the network when you are in the country where the eSIM is registered. If you installed the eSIM prior to traveling, it will only activate once you arrive at your destination. Ensure you are at the location associated with the eSIM for it to function properly.
What steps should I take if my eSIM is installed correctly but won’t connect?
If you are in the coverage area and the eSIM is properly installed, please follow these steps:
1. Disable Airplane Mode: Ensure that Airplane Mode is turned off on your device.
2. Enable Data Roaming: Go to your phone settings and enable data roaming for the eSIM.
3. Restart Your Phone: Restart your device and wait for up to 30 minutes, as it may take some time for the eSIM to connect to the internet.
4. Select Network Manually: Try manually selecting the network that the eSIM should connect to for internet access. This can often help establish a connection.
What if I still can’t connect to the internet after following these steps?
If you’ve completed these steps and still can’t connect, please contact customer support for further assistance at [email protected]
