WiFi calling allows mobile phones to use WiFi networks to place and receive calls even when a cellular connection to the carrier's wireless towers is weak or totally unavailable.

Device Support

Almost all new phones support WiFi calling, but it must be enabled on every phone. When you upgrade your phone, even if all other settings were restored from backup or your old phone, you must enable WiFi calling on the new device. This is a completely different setting than connecting your phone to WiFi.

Carrier Support

WiFi calling capable phones will have the WiFi calling option available only if the carrier supports it.

  • AT&T: Supports WiFi calling on all current phones.
  • Google Fi: WiFi calling is integral to service for phones that are "Designed for Fi".
  • Sprint: Supports WiFi calling on all current phones.
  • T-Mobile: Supports WiFi calling on all current phones.
