My son just switched over to a new-to-him Droid Maxx yesterday. He went to our local Verizon store and got a SIM card and activated the phone. It works great with the exception of no 4G (we're in an area with strong signal). He called Verizon's tech support yesterday and was told they gave him the wrong SIM card and to go back and switch it out. He did. Nothing changed. He still has no 4G signal. I have the identical phone and a strong 4G signal under the same roof. Any thoughts or suggestions would be greatly appreciated. He's currently at work, so any action on his part will not be possible until this evening, but I would certainly love to have some ideas or answers for him when he gets home. Thanks!
