Andrew wants to know how different Spectrum mobile is from Verizon. Leo says that Spectrum Mobile uses WiFi calling when users are home, but when users are out and about, Spectrum is just an MVNO that uses Verizon's network. The tricky part is a handoff from WiFi to the cellular network. But other than that, if one can save money on it, then why not? The only real negative is that some people may not have internet access with their routers. So, a phone could join a network and not be able to take or make calls because it's on a dead connection.
