Claim: Among the wireless communications service providers in the United States, Verizon is the only one that will continue to allow phones that don't support VoLTE, a standard high-speed wireless communication for mobile phones.
Evidence: On December 31, 2020, Verizon will no longer allow phones that don't support VoLTE to be activated on their network (tablets and hotspots can still be activated as long as they support LTE).
