What is Wi-Fi Calling?

Wi-Fi Calling uses your Wi-Fi network to boost your phone’s service. If you’re somewhere your cell signal is weak or can’t reach, like a basement, a rural area, or a building with thick walls, your phone can lean on Wi-Fi to keep your calls connected.

📌 Make sure your emergency address is set up

When you call 911 over Wi-Fi, this is the address emergency services use to find you. We'll show you how to below.

Common Wi-Fi Calling errors

Seeing one of these? Here's what to try.

Check your Wi-Fi connection and turn off any VPN. If you're on a work or public network, it may be blocking Wi-Fi Calling. Try a different network.

Your Wi-Fi signal may be too weak. Move closer to your router or switch to a stronger network.
