How do i know what is 3v and 5v?

What phone is it? Roughly old old is the SIM? If it's quite an old SIM that could create an issue, but it should still work okay.
There'll be a 16 digit number printed on the back of the SIM card, if it's a 3G SIM it should have 3G printed on the back, if it doesn't, pop along to your local O2 store and ask for a replacement SIM, don't worry, it'll be free!

Where did she buy the phone? Was it a reputable source? That's the message you would get if the handset was blocked.

The sim is only 2 months old(02) and the new phone(Alcatel) is from Carphone Warehouse.She was told the phone is open to any network but it won't accept the sim.
