When you hear the term Network Operator, it refers to the backbone companies responsible for providing mobile network services. In the U.S., these Network Operators include major players like Verizon, AT&T, and T-Mobile. They power connectivity through expansive infrastructure, ensuring that millions of users stay connected every day. However, there's more to this ecosystem, including MVNOs (Mobile Virtual Network Operators) that operate on multiple networks to offer unique services to customers.
