We have been having issues with AT&T left & right so we look up the highest leading phone company right now & T-Mobile it #1. We have been w/T-Mobile for 1-month and honestly I'd rather have AT&T service back. If I had known speeds on everything would be this bad and receiving txt or MMS would take forever even in popular areas to travel, I would have never switched. The hotspot is even worst it says we have 3 bars but nothing will load or load sooooo slow. So my question is we paid our devices off to switch to T-Mobile and they reimbursed us our payoff on each phone.. If we were to go back to AT&T would we have to pay back that reimbursement that T-Mobile gave us for switching to them??
I have Galaxy S10+ & my husband has an IPhone XS
