T-Mobile, identifiable by its Mobile Country Code (MCC) 310 and Mobile Network Code (MNC) 270, is a major mobile network operator serving the United States of America and Puerto Rico – placing it firmly in the North America & Caribbean region. Known for its disruptive "Un-carrier" strategy, T-Mobile has significantly impacted the US mobile landscape by eliminating contracts, offering free international data roaming in many countries, and pushing for improved data speeds and network coverage across the nation. The network covers much of the continental United States, Alaska, Hawaii, and Puerto Rico. T-Mobile's history involves a complex evolution of mergers and acquisitions, and some time ago bought out other mobile networks such as Sprint. Today it’s known for its competitive pricing and a strong 5G network rollout, rivalling AT&T and Verizon Wireless in terms of speed and coverage in many areas. They frequently launch promotions and initiatives aimed at attracting new subscribers from competing services. Alongside traditional mobile plans, T-Mobile also operates services like T-Mobile Home Internet, aiming to provide fixed wireless internet access to homes, further extending their reach within the telecommunications market in the USA.
