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
They offer SIM cards, or you can use it with any other carrier. And for the record, I’ve used visible wireless, mint mobile, cricket, and boost and they all work great. They’re just MVNO’s that ride on the big 3 carriers networks. Whatever has good coverage in your area will be fine. I haven’t used a major carrier in over 10 years.
