Claim: Among the wireless communications service providers in the United States, Verizon will no longer allow phones that don't support VoLTE, a standard high-speed wireless communication for mobile phones.
Evidence: In 2019, Verizon announced that they plan to shut down their CDMA2000 network by the end of 2020, making VoLTE the only way to make calls on their network. Voice over Long-Term Evolution (VoLTE) is a standard high-speed wireless communication for mobile phones and data terminals, including Internet of things (IoT) devices and wearables.
