    Can I just pop in my 3G sim card from a standard Cingular phone and use the same number I already have on the Treo 750?

    Thanks..

    if you can't, then something else is the problem. that's how sim cards are supposed to work. you have 1 sim card with your number. you just plug it in wherever you want.

    If you know that it is a 3g sim card, then it will work. Some older ones work also, and some don't, so you'll have to pop it in and see. But like I said, a 3g should work instantly.

    Would I have to call call Cingular with the IMEI number of the Treo or would the card just work by putting it into the treo?

    It will work right when you put it in, no need to call cingular. They cant tell what phone your using anyways....
