The cellular company you pay for your cell phone usage is either a mobile carrier or a mobile virtual network operator (MVNO). The United States has only a few licensed mobile carriers, but many MVNOs. U.S. Mobile Carriers Mobile carriers are large entities that must acquire a radio spectrum license from the U.S. government to operate in any region of the country. They own and operate extensive infrastructure in the regions where they offer service. The names of these telecommunication giants are familiar. Some of the most well-known mobile carriers in the United States include: Verizon WirelessT-MobileAT&T MobilitySprint If you don't see your mobile carrier on this list, you probably use one of the many mobile virtual network operators, some of which are subsidiaries or partners with one of the licensed cellular providers. Some MVNOs partner with more than one of the major carriers to provide service. Mobile phone users utilize cellular providers to support calling, texting, and data capabilities on their smartphones and other mobile devices. All major carriers support 3G and 4G calling, data plans, and a choice of several service plans. Mobile Virtual Network Operators U.S. mobile carriers are permitted to sell access to their radio spectrum to other companies that operate as mobile virtual network operators. MVNOs do not own the base station, spectrum, or infrastructure needed to transmit. Instead, they lease from a licensed operator in their area. They tend to operate regionally rather than nationwide and are smaller companies than the cellular companies from which they rent their radio spectrum. Some MVNOs are alternative brands of large mobile carriers such as: Cricket Wireless (AT&T)Metro by T-Mobile (T-Mobile)Spectrum Mobile (Verizon)Virgin Mobile (Sprint Corporation) Other examples of MVNOs include: Affinity CellularArmed Forces WirelessBoost MobileConsumer CellularEasyGO WirelessNetZeroPage Plus CellularStraight TalkTingTotal WirelessTracFone WirelessU.S. Cellular MVNOs often target small regions or niche segments of the population. Typically, MVNOs offer inexpensive monthly plans with no contracts and prepaid plans. They may not offer the same quality service or data speed as the mobile carrier they lease spectrum from, or they may be throttled at a specified usage point. You can port your existing number to an MVNO as long as you stay in the same area and bring your own phone, with some limitations. GSM and CDMA phones don't work on the same networks, but an unlocked phone has no such restrictions. Because MVNOs have low overhead costs, they usually spend aggressively on marketing to attract individuals to their service. In some cases, their customers receive lower priority than the customers of the bigger networks. Therefore, MVNOs may have lower data speeds. Typically MVNOs offer lower pricing and more diverse plans than the large carriers. Some MVNOs also provide attractive international calling options. They may be the only options available in rural areas of the country. Despite the downside of lower speed or possible throttling, MVNOs provide bargain service. They typically price out at half the cost of the large mobile providers.
