MVNOs, or Mobile Virtual Network Operators, are companies that provide mobile phone services without owning the wireless infrastructure. Instead, they lease network access from major carriers like Verizon or AT&T. This allows them to offer their own plans and pricing, often targeting specific customer needs or demographics. These operators can provide competitive pricing and unique services, such as flexible plans or specialized customer support. Because they don't invest in physical networks, MVNOs can focus on marketing and customer service, making them an attractive option for consumers looking for alternatives to traditional carriers.
