T-Mobile, operating in the United States of America (North America & Caribbean), is a major mobile network provider identified by its Mobile Country Code (MCC) of 310 and Mobile Network Code (MNC) of 210. Known for its disruptive "Un-carrier" strategies, T-Mobile has significantly impacted the US telecom landscape, challenging the dominance of competitors like Verizon and AT&T. They've achieved this through innovative pricing plans, elimination of contracts, and a focus on customer satisfaction, which includes features like international data roaming.
