honestly, you probably would only see a difference if you switched to Verizon since it seems like GSM towers aren't sending out a lot of juice in your direction. If you don't want to do that I would look at getting something like this: Amazon.com: zBoost ZB545 SOHO Dual Band Cell Phone Signal Booster for Home and Office, up to 2,500 sq. ft.: Cell Phones & Accessories

help? I have a Samsung SGH-A777 phone; an older 3g. I use it only to make and receive calls and the occasional photograph. In town it works great but 25 miles out of town at home I barely get a signal and it will not dial or receive calls. There are two towers about 10 miles away, almost line of sight. A small hill blocks a direct path. Other people's phones do work there but they have Verizon and not ATT as I do. Would a newer phone with a different chip work better?? We live in the boondocks and do not have any stores around that would give us a loaner to try overnight.. Ideas anyone? Thanks.
