Phone will not go to LTE and is stuck in 3G
My wife and daughter took their iPhone 6S Plus over to Japan for vacation and purchased a Japanese SIM card. When they returned home, their phones were stuck in 3G. I have done a complete factory reset 3 times as per the Verizon rep which did not make a difference. Apple was brought into the trouble shooting and was on a 3 way call with Verizon. Apple ran several tests which proved the phone to be working and that it was a carrier issue. Verizon has passed me along to all their tier support levels and I am not waiting for an Engineer to call me and work this out. I have been waiting nearly 5 days. Has anyone ever experienced this? I have located several things on the web but it's all the things I have already tried and nothing works. Verizon even sent me 2 new SIM cards to try and that did not work either.
Is this a good question?
