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
I’ve been on US Mobile for several years. You can choose between the Verizon, T-Mobile or AT&T networks. I’m on the Verizon SIM. Yes, you are deprioritized. No, it’s not an issue.
I’ve been very impressed with US Mobile’s support, though I’ve only needed it a couple times.
