Winegard Movin View: How to change sat settings under dome?

No, I would not recommend using any device which requires cellular access to watch TV. Satellite is really the only logical choice here if you will be traveling.
Many posts have been made about this being a MLM scheme including many calling it a scam. Even without that, it would be so expensive to find a good cellular plan that works everywhere you plan to travel and allows enough data for regular TV viewing I would still not recommend it.
