# Bmobile

bmobile is a Mobile Phone, Home Security provider, and fixed wireless provider of Trinidad and Tobago, operating as a division of TSTT.

## History

TSTT has re-branded its mobile division to bmobile along with other Cable & Wireless companies in the Caribbean. Since then, almost all the other Caribbean mobile divisions have been re-branded to LIME and now FLOW.
In 1991, they launched their AMPS network. This network was decommissioned on September 8, 2006. In 2002, bmobile launched its GSM network.
In 2007, they began launching data services (fixed wireless) on a CDMA2000 EVDO network. This was later upgraded to WiMAX and then to LTE. The network operates on LTE band 41 (2.5 GHz)
On June 14, 2011, they began to sell the Apple iPhone 3GS and iPhone 4.
In March 2014, the company announced 3G UMTS offering HSPA+ data services to all customers.
Part of its 5-year strategy, bmobile refreshed its brand and announced a launch of HD Voice over its 3G network as well as improved speeds by upgrading its existing HSPA+ network to support DC-HSPA+. Days later, on December 9, 2016, the company went live with its LTE network which, at the time of launch, was only available in Port of Spain, San Fernando, and soon after, a few locations in Tobago on LTE Band 2 (1900 MHz). Service was launched on LTE Band 28 (700 MHz) in October 2020 alongside the introduction of LTE-A. The company began broadcasting on LTE Band 4 (1700 MHz) in late 2022 and later launched 3 carrier-aggregation and 4x4 MIMO. 256 QAM is also active on the network. Voice over LTE services (VoLTE) were launched on January 29, 2025.
In order for bmobile to do an LTE rollout however, the company decommissioned its 2G GSM 1900 MHz network.
bmobile's parent company also purchased Massy Communications, now branded as AMPLIA, a move which saw the company increase its market share against the Caribbean-heavyweights, FLOW and Digicel. AMPLIA offers TV and fiber broadband services and also resells bmobile's landline and home security services.
