I got tired of my hubby standing on the roof of the rv to get a signal (work). So for 2017 Christmas I bought him a Wilson cell signal booster. It works with our Verizon cell service as a hot spot, has one exterior antenna on the top of the ladder (13' up) and an interior antenna by the booth dinette. He states it adds one bar to his usual service. Verizon has MN very well covered but some of our state park campgrounds have no or 1 bar service. This has improved and we can virtually always text and often have enough service for internet use. Hope that helps.
