SMS messages are typically limited to 160 characters and can be used for personal communication, business notifications, or alerts. This service is widely available on all mobile phones and does not require an Internet connection, making it a reliable way to communicate. SMS is often used for quick exchanges of information and is a fundamental feature of mobile phones, even as more advanced messaging services and apps have become popular.
