Mobile plans are subscription services offered by telecommunication companies that allow users to access mobile networks for calls, texts, and data. These plans typically come in various types, including prepaid and postpaid options, catering to different user needs and budgets. Most mobile plans include a set amount of data for internet usage, along with unlimited or limited voice calls and text messages. Users can choose plans based on their usage patterns, such as heavy data users or those who primarily make calls. Additional features may include international roaming and family sharing options.
