I see ads all the time for shit like consumer Cellular, mint mobile, stuff that rents time on Verizon towers and sells you a plan for like half the price.
I’m trying real hard to de-Xfinity myself but the cellular plan is the cheapest of all the major companies. Yes, I know they also piggyback off the Verizon network, but at least they have 24/7 support
As a primary internet source I could not recommend Visible. The de-prioritization was very noticeable and the coverage wasn’t great. (Even Verizon is piggybacking on some carriers in some areas - and in those areas Visible isn’t supported.)
I kept it around for a while for large file downloads - it was slow but I didn’t have to worry about data caps. Eventually I dropped it when I got a Starlink.
