Mobile Network Operators (MNOs) are companies that provide wireless communication services to customers. They own and manage the infrastructure needed for mobile networks, such as cell towers and antennas. MNOs allow people to make calls, send texts, and access the internet on their mobile devices. Some well-known MNOs include Verizon, AT&T, and T-Mobile. These operators offer various plans and services, catering to different needs and budgets. Customers can choose from prepaid or postpaid options, depending on how they prefer to pay for their usage. MNOs also often provide additional features like data plans, international roaming, and family plans to enhance the user experience.
