    It sounds as though the device is unlocked. Have you tried another carriers SIM in there?

    The phone is already unlocked to work on any GSM network. See the second screen shot here:
    What is MEP? | BlackBerryUnlocking.US | BlackBerry Unlocking | Unlock BlackBerry | BlackBerry Unlock Code | Unlock BlackBerry Bold Torch Curve Storm Pearl

    What does the signal strength meter show? As long as you've got bars and no SOS, the phone should be able to make calls.

    Does the SIM card you are trying to use work fine in other phones? Have you contacted t-mobile to see if there is an issue with the account?

    Hi there,

    you actually need to hold ALT key while typing MEPP2(or MEP2) - either of them, and make sure you dont press twice on any of the buttons - on the Flip to get P you need to press button twice - just press it once. So, in reality, you actually pressing 91OO2(91O2).
    Hope this helps,
