The ability to send and receive SMS and MMS messages on Android devices using a Wi-Fi network, instead of relying solely on a cellular connection, offers expanded communication options. For instance, if a user is in an area with weak or no cellular service but has a stable Wi-Fi connection, the user can still exchange messages. This functionality extends the reach of traditional text messaging.
This method of message transmission provides several advantages. It enables communication in locations where cellular signals are unreliable, such as basements or remote areas. It can also reduce or eliminate messaging costs, particularly when connected to free or unlimited Wi-Fi networks. Furthermore, the feature has evolved over time, becoming increasingly integrated into messaging applications and operating system features on Android platforms, enhancing user accessibility and convenience.
