What is the purpose of WiFi calling?
What is the purpose of WiFi calling? Wi-Fi calling is a voice service that lets users place and receive calls over a wireless internet connection, as opposed to using a cellular signal. Smartphone users can make use of Wi-Fi calling to talk and text on their smartphones from locations where it's difficult to reach a strong cellular phone signal.
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.
Is Wi-Fi calling risky?
Network security: When using a WiFi-calling service, your call is transmitted over the internet, which means it is vulnerable to being intercepted by hackers. To reduce this risk, make sure you are using a secure and trusted WiFi network.
