AT&T GoPhone SIM Compatibility Issues

An older Cingular/AT&T 2G sim card would look like the pictures in this ebay ad: NEW CINGULAR / AT&T 64K 2G SIM CARD Buy-It-Now-> $6.48 - eBay (item 290504788175 end time Dec-02-10 19:10:40 PST) Note their ad copy mentions Treo 650's have a similar issue rejecting the 3G cards.

An AT&T company or affiliate store might have one hanging around. Worst they can say is "no." Can't guarantee the 2g vs. 3g card issue is what's causing your service issue, but it's a possibility.

Do bring your old AT&T gophone with you to Mexico since you know it will work with your existing 3g sim card.

Enjoy your travels south of the border!
