that's pretty nice...AT&T also has WiFi calling if you have it enabled on your iphone, which i do...but AT&T treats WiFi calls practically the same as if you were using regular cell towers...so roaming and international long distance would still apply <img src="http://www.traveltalkonline.com/forums/images/graemlins/duh.gif" alt="" />

AT&T Wi-Fi Calling: Requires AT&T Wi-Fi Calling-capable smartphone with Internet connection via an existing Wi-Fi network. Once enabled, phone automatically makes and receives calls/text messages through Wi-Fi Calling only when AT&T network coverage is weak or unavailable. Charges: Domestic calls made/received within U.S., Puerto Rico, and the U.S. Virgin Islands have no additional charge and won’t count against plan usage limits. For international long distance calls, international rates under your existing rate plan or international package apply. All text messages sent/received are charged under your existing rate plan or international package and will count against usage limits. Service Limitations: Not available for use outside U.S., Puerto Rico, or the U.S. Virgin Islands.
