I recently bought the blackberry curve 8520 on pay as you go on o2, I recieved the handset and Put my other sim card in, which is my o2 simplicity contract. Many things are not working for example; BBM,Facebook app,Email. I have a feeling its obviously to do with using my simplicity sim instead of the pay as you go one they sent me. But is there anything i can do to keep my sim and get these things working ?

You need to change your tariff to the "Simplicity for Blackberry" tariff, which has blackberry data and will allow those things to work.

Ah I see, will this cost extra per month ?

Its a whole new tariff, so look them up online. You may have to pay more to get the same amount of minutes/texts you are getting now, but I don't know.
