So I've been having issues with my iPhone 5S and T-mobile for the past 6 months (dropped calls, data connectivity). I'm about to purchase the iPhone 6S and I'm debating on switching back to AT&T to get better service. Problem is that AT&T is still quite a bit more expensive (about $40 more) so if I could I'd rather stay with T-mobile. One of the things that the T-mobile customer service person said was that the atennas will be much better with the 6S for LTE service. I also looked online and saw that there is a known issue with T-mobile and iPhone 6 access to LTE band 12 and that they should address it with the latest release. Does anyone have any more info on this? Is it worth sticking with T-mobile to see if the 6S has better service with T-mobile? and more info is much appreciated. thanks!
