The ability to send and receive SMS/MMS using a Wi-Fi connection on devices operating with the Android operating system facilitates communication independent of a cellular network. This functionality allows users to exchange textual and multimedia content when a traditional cellular signal is weak, unavailable, or when roaming charges are a concern. For instance, a user located in a building with poor cellular reception can still send and receive messages if connected to a Wi-Fi network.
This capability is increasingly important due to the expanding availability of Wi-Fi hotspots and the rising cost of cellular data plans. It provides a cost-effective alternative to traditional SMS/MMS, particularly for users who communicate frequently. Historically, SMS/MMS relied solely on cellular networks; the integration of Wi-Fi represents a significant evolution in mobile communication, offering improved accessibility and potentially reduced expenses.
