can I use my AT&T sim card with a t-mobile phone since they are both using the GSM phone carrier? I also like a few Verizon phones so is it possible to use the AT&T sim card with Verizon as well? I know Verizon uses CDMA but I know they issue out Vodafone for when their customers travel, could I possibly put my AT&T sim card in the phone & have it work?
i have AT&T but want a t-mobile phone?
