Nextel

Nextel Brazil, operating under NII Holdings, Inc., was a prominent mobile network provider in Brazil and a key player in the South and Central American telecommunications landscape. Identifiable by its Mobile Country Code (MCC) of 724, representing Brazil, and Mobile Network Code (MNC) of 39, Nextel distinguished itself through its focus on business users, offering integrated digital enhanced network (iDEN) technology. This technology provided push-to-talk (PTT) services similar to traditional walkie-talkies, giving it a niche appeal amongst companies needing instant communication across their workforce. While Nextel faced stiff competition from larger Brazilian networks like Vivo (Telefônica Brasil), TIM Brasil, and Claro Brasil, it carved out a dedicated user base by emphasizing its PTT capabilities and data plans tailored for business needs. At its peak, Nextel offered nationwide coverage, but shifting market preferences towards 3G and 4G technologies presented challenges. NII Holdings eventually filed for bankruptcy protection and subsequently sold Nextel Brazil to América Móvil (Claro) in 2019, marking the end of the Nextel brand in Brazil. The 724 39 MCC/MNC allocation is now associated with Claro, representing the evolution of the Brazilian mobile network landscape.
