TDMA International Roaming
On May 31, 2007, TDMA international roaming was discontinued. AT&T TDMA and Analog subscribers can no longer make or receive calls while traveling outside of the U.S.
If you want to use your AT&T service while outside of the U.S., you will need to upgrade your wireless phone to GSM Technology. To ensure the broadest international coverage, we recommend a quad-band device that works on all the GSM network frequencies (850/1900 and 900/1800). Simply purchase an AT&T GSM world phone or visit your nearest AT&T Wireless location for more information.
