About T-Mobile

T-Mobile, operating in the United States of America (part of the North America & Caribbean region), is a major mobile network provider identified by its Mobile Country Code (MCC) of 310 and Mobile Network Code (MNC) of 490. As one of the 'Big Three' wireless carriers in the US, alongside Verizon and AT&T, T-Mobile has significantly shaped the telecommunications landscape. The network provides a wide range of services, spanning from basic voice and text to advanced 5G data connectivity. T-Mobile has expanded rapidly, particularly through strategic acquisitions such as its merger with Sprint, which occurred in 2020, substantially increasing the network's coverage and subscriber base. Known for its 'Un-carrier' strategy, T-Mobile has often disrupted the market with initiatives like eliminating contracts, offering unlimited data plans, and incorporating international roaming benefits. Its focus on customer service and innovative offerings has positioned it as a strong competitor within a highly competitive market. Users travelling within the United States, or international visitors relying on roaming agreements, often encounter T-Mobile's network identified by the MCC 310 and MNC 490, making it an important code combination to recognize within the context of mobile network identification. They have also been know to re-farm spectrum from older services such as 2G and 3G to allow for higher capacity 4G Voice over LTE (VoLTE) and 5G services.
