| AT&T | 1042 Arroyo Grande Dr | cell service used to be GREAT if fact they were so great i got rid of my land line. but 2 years ago they started to have connection problems and now are horrible. My calls always are dropped, or you cant be heard. texts take 3 to 4 hours to send maybe never sending. Att was the only carrier that you can have at this address, but for some reason att connection at my home is worse than ever. Verison has come into the area and now there service is better than att. When i called att many times with no help, in fact they finally said that I should get a land line or new cell phone carrier. i've had att for 9 1/2 years. there service is horrible | 2015 |
