Hey all - Well since I have joined here y'all have proven invaluable with your advice and opinions! I am currently on T-Mobile and using the iPhone 6+. I love how T-Mobile is introducing more competition into the industry but the service is still lacking for me. I live in Houston and as long as I stay in the metro area my signal is fine for the most part. But as soon as I leave Houston my iPhone becomes essentially useless. I drive across the country a few times a year and it's a real pain. Also, I get very very low signal when I am inside most buildings, especially my work building. I can't use Wi-Fi at work so the Wi-Fi calling isn't very useful to me. I have been thinking about going to AT&T but am wondering if I will notice much of an improvement. I know I may have to pay a little more, but after researching their plans it doesn't seem I will be paying THAT much more, and if the signal is improved I think it will be worth it to me. I am just wondering if I should expect better signal indoors with AT&T and better signal when I am outside of the metro area when I travel. Thanks!
