What is the downside of Wi-Fi calling?
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.
Can you text without service but with WiFi?
Tip: You can send texts over Wi-Fi even if you don't have cell service. Just use Messages as you normally would. If you're not connected to Wi-Fi, make sure cellular data is turned on: On your Android device, open the Settings app.
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.
Does Wi-Fi calling automatically switch to cellular?
When Wi-Fi Calling is available, “Wi-Fi” is displayed after your carrier name in the status bar, and all your calls go through Wi-Fi. Note: If the Wi-Fi connection is lost when you make calls, calls switch automatically to your carrier's cellular network using VoLTE (Voice over LTE), if available and turned on.
