Mobile operators are companies that provide wireless communication services to customers. They enable people to make phone calls, send text messages, and access the internet using mobile devices like smartphones and tablets. These operators own and maintain the necessary infrastructure, such as cell towers and network equipment, to deliver these services. There are different types of mobile operators, including network providers that own their infrastructure and mobile virtual network operators (MVNOs) that lease network access from larger providers. Customers typically choose a mobile operator based on factors like coverage, pricing, and available plans.
