Swapping A contract sim card to another phone?

[daz_zz_er]

Hey guys ive currently got a Sony ericssson Elm. Im paying £15 a month for my contract. I want to get a blackberry though, seen some cheap second hand ones in Cex. If i got one would i just be able to swap the sim and everything would be fine? And would i be allowed to sell my Sony Ericsson?

Yes you can sell your sony ericsson, with the sim card im not sure. I know with BB, people on contracts usually have a extra included which pays for BB services, such as bb messenger and their email service.

You may be able to add this as a bolt on to your contract though. Best calling your contract provider up.
