    Has it worked since you got it? What kind of signal are you getting? Does it say sos in the upper right hand corner next to the antenna icon? If so make sure you have the mobile network turned on under manage connections. Also if it is turned on make sure it says t mobile next to it. One time for no reason my 8820 was showing sos and my mobile network was on but somehow changed to att.
    There is also the old standby of pulling the battery while on, waiting 30 seconds then putting it back in.

    Hope this helps.
