4 Out of 5 (4 stars) | Loring Mill Rd., Sumter, SC 29150 |

I have AT&T and I live in Sumter and all of a sudden the last few days I've been getting lte instead of just 4g! Does anyone know if they are putting new towers up or what?

Sumter used to have great reception for AT&T. I am not sure what happened, but the last few months, data has been absolutely horrendous. Simple web pages load slowly or won't load at all and text messages fail to send. If this were happening in a remote area, I would understand, but this is in downtown historic Sumter around Main St., Liberty St., and the Cultural Center. I've also noticed that most of SC has LTE, Sumter is lacking this service however.

Service sucks. No internet at all what so ever. Hopefully they'll do better and throw up a few towers so we can really use these $300-$500 phones we got.

Coverage is very poor once you get past Cains Mill road heading West on Bethel Church road. Our howm is mile from the industrial park and we thought we would have good cell service with all the businesses in the vacinity.

3G at the end of 2013 is what I was promised. T-Mobile I am going to hold you to your word. A company is only as good as it's word. I am waiting... .

The voice reception seems to be good, but I did not realize at the time I bought my phone that the highest speed I could get, no matter where I am in Sumter, is only 2G (Edge)... .even though my phone is a 4G. C'mon T-mobile, even three years ago, when I was in Germany, I would get 3G almost everywhere. Needless to say, I cannot stream Pandora on the 2G network and therefore, the data plan I have is essentially useless. 2G is like dial-up around here... if you need faster speed, so with Verizon or AT&T.

Have lived here for 3 months and ever since we have lived in this house my phone has to stay in two spots in the house to get one to two bars. Then when I get a call I can't move from that spot! My husand has a smart phone and I don't, so the rep told him that it would be better if I had one so I could use wi-fi calling. How about that shouldn't matter.This was the last straw for me dealing with T-Mobile!

Constantly have dropped calls, signal goes from two to one bar in a blink of and eye. Half the time my calls go directly to voicemail and I dont get the message for a while after... .Called Sprint they were suppose to be researching and has now been going on for 6+months looks like I'll be searching for a new carrier, definitely tired of the run around.
