I'm trying hard to love the "$100 for 2 lines - no taxes" with T-Mobile, but I just don't know how much more I want to put up with some if its weaknesses: 1) at certain times inside buildings can't call or text 2) people can't hear me on the phone while I'm at home unless I switch LTE off for voice (live just south of Dallas) 3) inside buildings can't use data (can't browse, IG would hardly load, tried to set up a DVR recording but couldn't because no Internet) Well, I'm not exactly sure how much is T-Mobile's network's fault OR my iphone 7+'s weaker mobile Intel chip (as opposed to Qualcomm). With AT&T none of these were an issue with an ip6, well except at my in-laws' I couldn't reach my wife (no service there where T-Mo somehow could). If I go back to AT&T would my T-Mobile 7+ have any issues? I assume I can't use that T-Mobile 7+ on Verizon since different technologies, right? Any other suggestions? Thanks!
