Hi,
I had ST (AT&T) with a Moto G3. All worked fine. I recently purchased an ST Moto G7. When I activated and retired the old phone the G7 phone registered me with ST using Verizon. It all works fine in Frederick County MD and Eastward toward Washington DC and Baltimore. If I go west to Washington County MD. The phone asks for a roaming pin to make calls and will not receive calls. My wife's ST Moto G6 on Verizon works fine in the same area. My new G7 has never worked in Washington County MD (always wants roaming code).
I tried contacting ST chat support after a script of questions was told to call them the next time I had the issue in the Washington County area. Since the phone will not let me make calls without a roaming code this would be pretty challenging! I have a case number if that would help? I'd like to believe this issue could be escalated to someone smarter than the standard ST agent I had on the chat.
Thanks
