Which technology is primarily used for sending text messages?

The technology primarily used for sending text messages is cell phone technology. This encompasses various mobile network technologies, such as GSM, CDMA, and LTE, which are specifically designed to support voice and data transmission, including SMS (Short Message Service) functionality. When a user sends a text message, it is transmitted over the mobile network, passing through cell towers that facilitate communication between devices.

While Wi-Fi can also be used for messaging apps that send texts over the internet, traditional text messaging specifically relies on cellular networks, which is why cell phone technology is the most direct answer to sending text messages. Satellite communication is primarily utilized for long-distance communications and not typically for everyday text messaging, and broadband refers to high-speed internet access, which does not pertain to SMS in a direct sense. Thus, the focus on cell phone technology accurately identifies the core method for sending standard text messages.
