Unlocking an old phone without being on o2

[MS84Sk]

Hi there!

I’ve recently been given an old phone that is apparently locked to 02. I would like to unlock it to put in a Virgin sim as this isn’t recognised on the phone (iPhone 7). I can’t log into 02 as I’m not on this network! That seems to be the answer everyone gives but isn’t available to me. I have also clicked a ‘manual link’ but this never works either and I can’t contact 02 as I can’t log into My02 without being on the network. 

Please someone help?

Thanks.

You need to get an O2 payg sim to register the phone on the network and provide yourself with the required details. Guide: Unlocking an O2 phone to use a different SIM card
