Last year, or maybe the year before, we bought a portable weBoost to test on our mountain property. It was simple. Plug into the 12v cigarette lighter outlet, put the antenna outside through the window. Portable means kind of "deploy every time."
Unfortunately. we had zero tmobile signal, anywhere, when I did scans with our tmobile devices, so I returned it. You have to have some very weak signal to boost....
Our Verizon devices already worked fine. But, we did get a boost on the Verizon.
That's why we carry devices from two carriers when we travel. Usually, if there's any signal at all, either tmobile or Verizon can connect.
