It depends on who you speak with at T-Mobile. I passed the question on the T-Mobile site and received several calls, each with a different answer. One said they couldn’t guarantee 5G service everywhere but I explained I was looking for that, just a more secure service. Another said absolutely not, the unit had to stay at our residence. One gal wouldn’t even talk to me and hung up. I still think we’re going with this T-Mobile Home Internet.
