Sony Xperia™ M2 support.
Using a PUK code.
If you enter the wrong PIN three times, your SIM will become locked. You'll need a PUK code to unlock the SIM. Call us on 333 from a Three phone or 0333 338 1001 (standard rates apply) from any other phone to request a PUK code.
Note: Don't try to unlock the SIM without the correct PUK code as this will block your SIM completely. If it gets blocked, you'll lose all the information stored on your SIM and you'll need to get a new SIM.
To unlock your phone with a PUK code:
If you've locked your SIM PIN you'll see the message below. Tap OK
Enter the PUK code provided then tap the enter key
Enter your new PIN and tap the enter key
You'll be asked to confirm your new PIN. Tap the enter key
Your SIM will now be unlocked.
Seems we made things right.
