Yes, it is possible to get SMS messages without a cellular network connection, primarily through Wi-Fi Calling.
Wi-Fi Calling for SMS
If you can't get a cellular signal, but you have a Wi-Fi connection, you can still receive SMS messages if your carrier supports Wi-Fi Calling. This feature allows your phone to connect to your carrier's network over Wi-Fi, essentially mimicking a cellular tower connection.
How Wi-Fi Calling Works:
- Your phone establishes a connection to a Wi-Fi network.
- If Wi-Fi Calling is enabled and supported by your carrier, your phone uses this Wi-Fi connection to connect to your carrier's network.
- Your phone then functions as if it were connected to a cellular tower. (Reference: Wi-Fi Calling builds a connection over the Wi-Fi network and then behaves as if it were connected to a cellular tower)
Requirements for Wi-Fi Calling:
- Carrier Support: Your cellular carrier must support Wi-Fi Calling.
- Compatible Phone: Your phone must be compatible with Wi-Fi Calling. Most modern smartphones support this feature.
- Wi-Fi Connection: You need a stable and reliable Wi-Fi connection.
- Wi-Fi Calling Enabled: You must enable Wi-Fi Calling in your phone's settings.
Benefits of Wi-Fi Calling:
- Receive SMS without Cellular Signal: You can receive SMS messages even when you have no cellular signal.
- Make and Receive Calls: Wi-Fi Calling also allows you to make and receive phone calls over Wi-Fi. (Reference: You can get phone calls and SMS messages through a Wi-Fi connection to the carrier)
- Improved Coverage: Wi-Fi Calling can improve coverage in areas where cellular signal is weak or non-existent.
