The capability to transmit messages over a wireless network on Google’s mobile operating system refers to utilizing a Wi-Fi connection instead of a cellular network to deliver Short Message Service (SMS) or Multimedia Messaging Service (MMS) messages. This functionality enables communication even in areas with weak or non-existent cellular coverage, provided a Wi-Fi network is available. For instance, a user might employ this method when traveling internationally to avoid roaming charges or in a building where cellular signals are obstructed.
This method of communication offers several advantages. It can reduce reliance on cellular data plans, potentially lowering communication costs. Furthermore, it can improve message delivery rates in locations where Wi-Fi connectivity is more reliable than cellular service. Historically, this function has gained prominence with the increasing availability of Wi-Fi hotspots and the rise of data-centric communication models. The option also provides a solution for devices primarily used with Wi-Fi, such as tablets, to send and receive text messages.
