Been using Visible for over a year and a half now with great success. There have been a few places where we encountered a "dead zone". But then, our AT&T phone service did not work either.
We just upgraded to the 5g service (like today) as the last couple places we've been had intermittent casheing problems on our Roku televisions.
Buy the way, Visible allows only 1 device to be connected at a time. If you attempt to connect a second device, it simply will not.
To get around this, you'll need to pick up a portable router. Only 1 device is connected to the actual phone, that's the router. Everything else is connected to the router's hot spot or WIFI, so multiple things can be running at the same time. And by the way, running multiple devices, like a Roku streaming television and working remotely on a Skype call on your company laptop works almost flawless too!
We have the GTE phone from Visible (It was the $79 version). It came with the SIM card. Since we are upgrading we'll be getting a new SIM card. We are not at home right now (camping in Kentucky at the moment), so it will be next week before we can try the new G5.
The router is a GL.iNet. It allows hook-up to 4g and 5g systems.

The nice thing is, you can take this anywhere! You are not confined to the limits of your camper only this way. Want to go on a picnic on the top of a mountain ... take the phone and the router with you! Presto! Instant internet.
Disclaimer: we have had a few incidents where we could not stream with our Roku television, yet we could stream when we used our lap top computers. It made no sense, unless there is something going on with the televisions that technology has already exceeded for that television.
