I have just bought a second hand Galaxy S7 which is apparently locked to THREE. The THREE logo is on the start-up screen and I can't get rid of it. I have put my new nano sim card in, but the phone does not seem to recognise it. (Apparently the S7 is unlocked to all networks ????)
I still have my old phone working with the existing sim card , do I have to "verify" the new nano sim before it will work ? I thought the phone would automatically recognise it and then refuse to connect.
I don't want to "verify" the new sim until I can be sure that it will work in the new phone or I will be left with two useless phones !
