What is VoLTE?
Voice Over LTE (VoLTE) is the current network standard, bringing you great features unavailable with older
phones. Enjoy clearer sounding calls, the ability to search the web and use GPS while on a call*, and an
improved battery life.
If your phone doesn’t support VoLTE, you will face connection issues like dropped calls
and poor reception. This will eventually lead to total loss of service, and you will not be able to make or
receive calls, including emergency or 911 calls.
*Some features may only be available for Smartphones.
