I have an old Samsung Galaxy A8 from 2018. It's not been used for over 3 years. My daughter is going to use it now. It tried to unlock it via the IMEI number on the EE website. It says its unlocked and given me a 16 digit code. However, the SIM I have put in the old phone is coming up as invalid and it says SIM network PIN blocked. Enter SIM network PUK. I phoned customer services and they were no help. I have been informed its 100% not unlocked and EE need to provide the PUK. How can I get it and get sorted?
