I have an ATT iPhone 6S that I recently switched to T-Mobile but the coverage is spotty at best in Southern NJ. I think the phone can also be used with Verizon or am I wrong? When I checked on their web site it said the IMEI # was not able to be used on their network but when I called them they said they could add it to their database and make it work. Is this correct? Would doing a restore on the iPhone maybe help the T-Mobile signal issues since it originally was on ATT's network? I know the carrier settings were updated when we made the switch. Personally where I seem to travel the service is ok with but my wife is having a lot of issues.
Straight Talk Wireless is an option for her but I am not sure what network they use in Southern NJ, ATT or Tmobile. If anyone knows please let me know.
They also have Verizon but again the IMEI # is not showing in their database.
