    I have a global sim that works fine on a Motorola "dumb" phone. But when I put it in my unlocked 9550 and try to make a call, I get back some encrypted garbage.

    I have changed the settings to GSM to try this. Is this happening because I can't use the SIM in the US on GSM with Verizon ?.

    Verizon only uses CDMA in the US, only outside the US does Verizon use GSM.

    Got it....thanks!. So, if and when I travel abroad, and switch to GSM the Global card "should" complete a call without returning this encrypted message ?.

    I guess I'm also trying to confirm:
    NO global sim will work on my Verizon 9550 in the US on ANY settings ?.

    Thanks again

    Um actually thats incorrect. You can use either gsm or cdma on the storm1 or 2. Might have to ensure the network is set to 2G.
