Symptoms
- Transfer process shows an error partway through
- New phone shows no service after 'successful' transfer
- Old phone loses service but new phone doesn't gain it
- QR code or transfer prompt doesn't appear as expected
Likely causes
- CommonWeak Wi-Fi or Bluetooth connection during the transferDirect phone-to-phone eSIM transfers rely on a stable local connection between devices.
- CommonPhones not kept close together and both powered on during transferBluetooth-based transfers need close proximity throughout the process.
- PossibleCarrier account needs manual assistance to reissue the eSIMSome carriers require you to contact them directly for eSIM transfers, especially between different phone brands.
- PossibleOld phone already erased before completing the transferWiping the old phone too early can interrupt an in-progress transfer.
- Less commonCarrier-specific app needed to complete the transfer wasn't usedSome carriers require their own app rather than the phone's built-in transfer tool.
What to do
- Keep both phones powered on, close together, and connected to Wi-Fi during the entire transfer process.
- Avoid erasing or resetting the old phone until the new one confirms it has active service.
- Retry the built-in transfer process from the new phone's cellular settings.
- Check if your carrier has its own app or website tool specifically for eSIM transfers.
- Contact your carrier directly if the transfer keeps failing; they can often reissue the eSIM remotely.
- Have your account information and the old device's details ready when contacting the carrier.
- As a temporary fallback, ask if a physical SIM card can be issued while the eSIM issue is resolved.
When to call a pro
If self-service transfer keeps failing, contact your carrier's support directly, since they can reissue the eSIM profile from their end.
