My SIM is asking for a PUK code

A PUK (Personal Unblocking Key) is a security code your device asks for after the SIM PIN has been entered incorrectly too many times. You cannot skip it — the PUK must be entered to unlock the SIM.

Find your PUK code

PUK codes are carrier-specific. To get yours:

• Open the app and check under Account, SIM details, or Plan settings — some apps display the PUK directly
• Contact support through the app with your subscription reference and request the PUK code

Enter the PUK code

When prompted on your device, enter the PUK code. You will then be asked to set a new SIM PIN.

• Choose a PIN you will remember
• Avoid obvious combinations like 0000 or 1234

If the SIM is permanently blocked

If the maximum PUK attempts were exceeded and the SIM is blocked:

• Contact support through the app to request a new eSIM profile
• Your number and subscription will remain active — only the profile needs to be reissued

This article doesn't cover:

eSIM locked for a different reason → eSIM locked, already in use, or showing duplicate profile

eSIM deleted and needs reinstalling → My eSIM was deleted — can I reinstall it?
