How to check whether your phone supports eSIM
Use model information, lock status, and device settings before making the required checkout attestation.
4 minute read · Updated 2026-07-31Identify the exact model
A product family name is not always enough because regional variants can differ. Check the model identifier in device settings or the original purchase record.
Review the Aelixar device catalogue guidance for the UK market.
- Find the model identifier
- Review catalogue guidance
- Do not rely on appearance alone
Confirm that the phone is unlocked
A technically compatible phone may still reject another service when it is locked to a previous network. Review lock status in settings or contact the current provider.
Complete any unlock process before starting a number transfer.
- Check network lock
- Finish unlock requirements
- Confirm eSIM settings are available
Understand the attestation
UK eSIM checkout asks the customer to confirm that the device is unlocked and eSIM capable. This is customer confirmation, not a provider IMEI approval.
Choose physical SIM when the exact model cannot be confirmed.
- Read the confirmation carefully
- Use a stable Wi-Fi connection
- Keep current service until ready
