I live in little Rhode Island in a town where there is 3G only. BUT, occasionally, my phone will display 4G either late at night or early in the morning. I'm sure this messes with my data connection, because data connection has been unreliable during the day. Anyone else share this same issue? Calling Verizon is no help--this is one area they are very gray on. And it angers me when they tell me to send back my phone and get a refurb one. I paid for a NEW phone.
Possible network improvements being worked on in your area. Warranty replacements are always refurbished devices. Your phone isn't technically new either. It is now a "used" phone.
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
