Glossary Definition for: VoLTE

It used to be to make a voice phone call, cell phones switched their radios back to the old voice network to make the call. This is why some older Verizon phones can’t surf the web or get email while a call is underway, and AT&T phones drop back to 3G data speeds until the call is completed.

Voice over LTE changes things up by sending your voice call as data over the 4G/LTE data network. This keeps your data connection running full speed and allows for HD Voice, which will let your voice calls to other VoLTE phones come through sounding more CD-quality than AM radio.
