I have been given a phone type Nokia 6310i and when I put my Sim Vodephone card from my Nokia 1100 in, it wont recognise or let me use phone any suggestions on how to get phone to work. Sim card works ok when I put it back in 1100
If both PHONES are not set up to recieve service from same service provider it will never work.
Eg you're on 02 (and obviously have an 02 sim) in a phone provided by 02 (or shop knowing you're going on 02) God i'm waffling already!!!!
If you were to take that Sim out of your phone and put it into phone from firend (maybe who was on Vodaphone for eg) it probably wouldn't work. I know that some are compatible and some are def not compatible.
