    Hi i got almost same problem.
    My iphone 5 shows carrier name and 3g or edge symbol but when signal ball drops to three balls, i cannot call, receive calls or messages. This happens when signal balls drops to three bars. when its four balls ican call but call often drops, when it is five balls i can call, message etc.

    after Deddoman said me about r-sim i gone to control again what i obtained after imei control and one voice say the phone was activated in my country but Along with Tim carrier and when i try to use my Wind sim it dont work…i tested too some components to see if there is hardware faulty but i think Deddoman solution can solve my problem…im waiting my R-sim 9+ and after i installed let you know if it work
