No reception

[anon(749368)]

So this weekend we went to Lake George, NY and to our surprise there was no signal there on t-mobile (no voice or data). In those cases, shouldn't the phone jump on another carrier and roam? This never happened to our S6. And what's more weird is that, according to t-mobile coverage map, we should have 4G

It can jump to AT&T to Roam but only if they have agreements within that area.

That roaming issue could be changing soon if you have a phone that supports VoLTE on T-Mobile

Band 12 should fix this is your phone is capable, its almost a day and night difference.
