What happens when I turn on Wi-Fi calling?
What happens when I turn on Wi-Fi calling? Wi-Fi Calling lets you make and receive voice calls, texts and video calls over a Wi-Fi network instead of using a cellular network. Try using Wi-Fi Calling if your cellular network service is weak or unavailable and Wi-Fi is available.
What is the downside of Wi-Fi calling?
With overloaded networks, you'll experience slower cellular data speeds because you are sharing bandwidth with everyone around you. Weak signal strength can result in poor voice call quality and dropped calls. Some devices don't support WiFi calling. You must have a smartphone with built-in WiFi calling capabilities.
What happens when someone texts you when you have no service?
The sender sends the message to their carrier, where it is stored and then forwarded to the recipient's carrier. If the recipient's carrier cannot be reached, the message is retried for a period of time - hours at least and perhaps days.
