1900 Mhz

put you zip code in the front page of this website. It should tell you what frequencies ATT is licensed to provide service. I don't know if that will answer your question, but it may be a start. Can anyone else verify this theory for me?

 

I wouldn't chose a 1900 MHz only phone for use with AT&T Mobility. You can find a map of their single band coverage at the GSM Forum, an industry association.

NOT RECOMMENDED. Don't complain here when your coverage sucks with that phone.

 

If you're dead set on a 1900MHz-only phone, forget about AT&T, use T-Mobile instead.
