This is an error that only occurs on Android devices, in rare cases when the device fails to successfully download the Roamless eSIM
Potential Solution
If you see the Roamless eSIM under SIM Manager, please click into it and see if you can delete it
Check your connectivity and if possible change your WiFi connection (or hotspot to a different device)
Make sure any VPN services are disabled on your device
Try to install the Roamless eSIM again
If you do not see the Roamless eSIM under SIM Manager, and you try again, you may get a "This code has expired / This code is already used" error, indicating that the eSIM was downloaded but is stuck in an error state and is not usable.
In case the above steps do not work, please reach out to the Support Team so that we can assist you in person.
