AT&T is best for international use; their phones are GSM-based, which is the typical standard in the rest of the world. Verizon and Sprint phones typically operate with incompatible technology.

So true. When I went to the Philippines, there are markets where they actually replace the card for both Blackberry and Iphone that makes calling local free without charging the overseas call.

AT&T is a GSM network and that is common in the world... Verizon and Sprint are CDMA network less common but Verizon and Sprint have phones that work on both CDMA and GSM network so geting a "World phone" from Verizon and Sprint is not a problem...

I'm on a Sprint SERO plan for 500 min a month plus unlimited Internet and text for $30 a month (grandfathered in) and have a HTC Touch 2 "World phone" that does both CDMA and GSM
