A mobile carrier is a company that provides wireless communication services to customers. They allow people to make phone calls, send text messages, and access the internet on their mobile devices, such as smartphones and tablets. Some well-known mobile carriers include Verizon, AT&T, and T-Mobile. These companies own the network infrastructure that enables communication over long distances. Mobile carriers offer various plans and services, which can include unlimited data, family plans, and international calling options. Customers typically choose a carrier based on coverage, pricing, and the types of devices they want to use. The competition among carriers helps improve service quality and offers more choices for consumers.
