Text messages are short written communications sent between mobile devices, typically using a cellular network. They allow users to quickly share information, ask questions, or stay in touch with friends and family. Text messaging is popular due to its convenience and speed, making it a preferred method of communication for many people. Most text messages are limited to 160 characters, although many modern messaging apps allow for longer messages and additional features like emojis and multimedia sharing. Text messaging can be done through various platforms, including SMS (Short Message Service) and instant messaging apps like WhatsApp and iMessage.
