Your phone can become blocked if you enter the wrong SIM card PIN number 3 times in a row. To unblock your SIM you’ll need a PUK (Personal Unblocking Key) code.
Remember that unblocking is different to unlocking. Find out more about unlocking your device.
The quickest way to get a PUK code is to log in to EE:
Go to Menu >Manage device
scroll down to Unblock SIM (PUK code)
select Show PUK code
Once you have your PUK code, enter this into your phone to unblock your SIM.
Take care when you enter your PUK code into your phone, you'll block your SIM card again if you enter the wrong code 10 times in a row.
