I have posted my troubles in different ways with the 7+ (south Dallas). Am I the only one that has a virtually unusable phone if you're in a building if there's no wifi? I've been in stores and restaurants with no wifi (Target, Walmart, Jasons Deli for example), and if I leave the LTE on I can't do anything. Once I turn off LTE, if 4g is available, it's a little better. Still can't make calls though. It's getting very frustrating. Do those of you with T-mobile just not use your phones inside buildings? I switched a few weeks ago from AT&T to T-Mobile, but this just isn't working out so well. Very seriously considering going back to AT&T (will be cheaper for me since I have DTV), and I really want to try VZ (will cost more though). I like some things about T-mobile (Tuesdays, been working good in the car, fairly well at home, pretty good customer service so far), but I honestly feel like I can only use my phone well in those 2 places (home or car). While at a red light I sometimes test my LTE speeds, and they have been over 100mbps a couple of times. Once I'm inside a building though forget about it! I feel like my phone is unusable half the time. Any other advice/tips are appreciated!
