bmobile Trinidad & Tobago, a telecommunications company, operates as a division of the Telecommunications Services of Trinidad and Tobago (TSTT). The company was initially launched as the mobile division of TSTT and has undergone several re-brandings, eventually adopting the bmobile name. It launched its Advanced Mobile Phone Service (AMPS) network in 1991, which was later decommissioned in 2006. In 2002, bmobile introduced its Global System for Mobile Communications (GSM) network.
The company further expanded its services in 2007 by launching data services on a Code Division Multiple Access 2000 (CDMA2000) Evolution-Data Optimized (EVDO) network. This network was later upgraded to Worldwide Interoperability for Microwave Access (WiMAX), and then to Long-Term Evolution (LTE). As part of its growth strategy, bmobile refreshed its brand and improved its services by upgrading its existing High-Speed Packet Access Plus (HSPA+) network to support Dual Carrier High-Speed Packet Access Plus (DC-HSPA+). In 2016, the company launched its LTE network, which has seen subsequent updates and expansions. In a significant corporate move, bmobile's parent company TSTT acquired Massy Communications, now branded as AMPLIA, further strengthening its market position against Caribbean competitors such as FLOW and Digicel.
