    Turn off 3G. What is your iPhone's baseband?

    Make sure you have 3G off if you're on T-Mobile in the U.S.

    Also, make sure you have the sim card cut to size and the chip isn't damaged.

    If you turn off 3G do you get much slower transfer speeds?

    No, with Tmobile USA you don't get 3G just edge.
    Leaving 3G on causes problems with signal fluctuation.
