Thanks. Do you have an older iPhone or the new 6S's? Reason I ask is that the newer ones include Band 12 which is supposed to improve indoor coverage with T-Mobile. I have a Sim Free 6S Plus on order which also includes band 12, so I should be ok.
Yeah I have the 6s Plus unlocked from AT&T. I'm guessing T-Mobile hasn't activated band 12 coverage in my area yet. All in all its not too bad. I'm still able to get things done quickly enough even on 4G, though that's what I miss the most leaving AT&T; great indoor coverage.
