No reception, or a lot of dropped calls whenever you do get reception. I have been with T-Mobile for many many years, and this is the worst ever. I no longer have contracts with them, so I might look for something better if this doesn't clear up soon.

Excellent Tech support (Thanks Tom) and customer service. My I-Phone 4 (officially unlocked - $1000 from UK - I just hate contracts) works great except the Data channels for 3G / 4G not compatible with T-Mobile. I only get 2G service for Data speeds. It should be OK for everyone if they merge with AT&T (not less than 1 year).

AT&T IS HORRIBLE IN HOUSTON. I have both AT&T and Verizon phones. The AT&T phone is pretty much a paperweight. The Verizon phone works great pretty much everywhere, even in the elevators and the tunnels. Go Verizon!

Nearly impossible to make and stay connected during a conversation.

Below average outside and Poor inside home

Signal is 3G only and Strength is a mere 28% in my office. Verizon has a much stronger signal in the same location.

Very poor reception in a 1 to 2 mile radius or more surrounding this area. Dropped calls, poor reception, no reception and no 3G.

Horrible reception, either no data, slow 3G or sometimes Edge only. AT&T says they have a problem but have been "working on it" for months now. It seems to worse every day.

I've had all the big carriers... .AT&T, Sprint, T-Mobile, and Nextel. Nothing measures up to Verizon. Even in elevators in the Williams Towers, my services is flawless. You get what you pay for, and coming from AT&T, thats horrible service in the Houston Area.

Phone had reception up until April 8th 2011, now I cannot receive phone calls or text but the apps (Facebook, Twitter) still work. I currently pick up someone from the Metro bus stops and it isn't safe to be without a line of communication..especially for women. Get it together Sprint or lose a 10 yr plus customer (with multiple lines).

Verizon customer for almost 10 years. We've never had more than 2 bars (out of 5) in the house, and normally it's either 1 bar, or no service. We've had Verizon tech people to the house... they say it's just a bad service area, due to lots of trees and other obstructions. But, they continue to take our money, even though we can't make a call from our home. Service around town is usually pretty good.

I work in the Med Center, and my reception has gone from poor to none lately at work AND at home (home is on Bissonnet) - this is incredibly frustrating because the only time I have coverage is when I'm transiting which is maybe twenty minutes a day. Several people I've spoken to with iPhones complain of this problem at the med center. Why won't AT&T give this area more towers?

On a lease out of Streeter, TX (5 miles from Mason,TX), there is no reception. We were stuck with no vehicle for 6 hours and could not reach out for help.

My girl went to reynosa Mexico n she was talking to me in Houston while the cops were havin a shootout with the cartel outside of the building she was in

All of a sudden this part of downtown has next to no service. Never had a problem until this year. It takes forever data to load, I have no access to wifi. Service seems to have suffered lately not just downtown but all over Houston.

No service this morning; then lousy connections with dropped calls. I thought AT&T was a "major player" in cell phones. If that's the case, then they'd better clean up their act in Houston or they've lost me as a subscriber. Their service is sub-par and pathetic.

Very poor receptions. 4G almost non-exist. In some open areas slightly outside of TMC (Fannin / S. Braeswood arear), now even don't have 3G signals.

Reception in this area still sucks over 2 years since Hurricane Ike. It was just ok before but no more than 3 bars outside and variable poor to nothing indoors with most calls over 3 mins getting dropped. Several calls to ATT nothing changed

I have had pretty good luck with my T-Mobile G1 for over a year now. Signal is nearly always strong and clear. Occasional Data issues, but I expect every service to have a few hiccups. Customer Service has always been very good as well.

while in my home I can not make or receive calls. I have had Sprint for about 11 years now.
