Great service town is less than a mile from the house.

I have had no fewer than three bars throughout Sierra Vista.

best service ever! been with Alltel for 8 years onle ever droped 2 calls!

I'm visiting from the Philippines and I'm roaming on Cingular's Network. I can travel all around the Sierra Vista area, up 90 to I-10, and there are only a few places with no signal before I get to and on the freeway. Every once in awhile my signal will drop to 3 bars, but most of the time it stays at 5 or 4 bars.

Works good everywhere except on 92 around palominas and the san pedro. On 82, it just recently got stronger and no more lost calls from Sierra Vista to Bisbee on 82.

AT&T does not support 3G in Sierra Vista. My family has two Apple iPhones. The Apple iPhone 3G indicates 3 to 4 bars until we enter a building then service suffers. Inside or outside the AT&T data network and phone service is pathetic even when the the iPhone shows 3 to 4 bars! Most times I have to place the call twice before the network puts the call through.

Good Service EXCEPT there is NO 3G! really sucks actually since I got this phone for data specifically.

Had Sprint (which was okay) and T-Mobile (no bars ever even though there is a tower 1.5 miles away) and Cingular's service is much better by far, no questions asked. Most of the time I get 3-4 bars with Cingular, and many times 5.

However I get good reception. My calls will drop continously after 3-10 seconds on my phone. I hate this service. I do not recommend

Indoor was a problem until T-Mobile put up a new tower next to the Windemere Hotel (looks like a tree!). Now it is acceptable in some rooms, others not. Outside around town and on the fort is always great.
