There is no reception here for my Verizon phone. I have to drive up a hill to get it.

No coverage in any of the Chesapeake Haven locations. Very erratic on Grove Neck Rd.until Cecilton. Switched from Verizon to AT and T in 2006, no coverage on either carrier even though coverage maps on AT and T say moderate coverage and Veriozn full coverage and 3G - not the case!

Inside the building, don't even expect to get any Sprint coverage. Also, inside most buildings (Engineering, Armory, etc) Sprint doesn't work. Oddly enough, I don't get any reception at the open mall.

Since last Sunday 10 / 10 / 10, Sprint has no service at this location. No calls can be made or received. No access to voice messages either. The same cellphone works in other places perfectly fine though. I have called customer service multiple times, they have no idea what is going on but one of the reps admitted that recently they have had outings in this area. Overall, very poor customer service. I will change my carrier as soon as I get a chance.

No / Poor signal in Milestone shopping center, such as inside Kohl's, Target and Walmart.

My ATT cell (which is frequently better than most out in the boondocks) is essentially useless at my GSFC office, and at the local Co-op market, and at the local so-called mall (Target has one corner with semi-service). According to the company, issues at a single site on one of our taller buildings is to blame but I believe (and have told them) that service has stunk since they bought Cingular. If anyone in Greenbelt says they get 'good' service from ATT, then I'm betting they are working for the company.

I live in the basement of the house. I have ZERO bars in my basement and one (if I am lucky) up stairs. I wish T-Mobile would put up some more satellites around my house. I've been with T-Mobile for over 6 years now. The only reason I am still with them is because of the Customer Service!

signal drops out completely, you have to finish call prior to getting on shore drive

I just purchased an Iphone 4 and AT&T service. I get 4 bars in downtown Oakland MD but two blocks away at my home I have "no service." I just dropped US Cellular which was outstanding. I guess I'll have to go back to US Cellular.

Me again. Had 4 now have Roaming. How the heck does this happen? The phone can't seem to find a happy medium. Shoulda kept my yap shut. I guess I jinxed myself.
