'''bmobile''' is a Mobile Phone, Home Security provider, and fixed wireless provider of Trinidad and Tobago, operating as a division of [TSTT](/source/TSTT).

==History==
TSTT has re-branded its mobile division to bmobile along with other [Cable & Wireless](/source/Cable_%26_Wireless_Communications) companies in the Caribbean. Since then, almost all the other Caribbean mobile divisions have been re-branded to [LIME](/source/LIME_(Cable_%26_Wireless)) and now [FLOW](/source/Flow_(brand)).

In 1991, they launched their [AMPS](/source/Advanced_Mobile_Phone_System) network. This network was decommissioned on September 8, 2006. In 2002, bmobile launched its [GSM](/source/GSM) network.

In 2007, they began launching data services (fixed wireless) on a [CDMA2000](/source/CDMA2000) [EVDO](/source/EVDO) network. This was later upgraded to [WiMAX](/source/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](/source/Apple_Inc.) [iPhone 3GS](/source/iPhone_3GS) and [iPhone 4](/source/iPhone_4).

In March 2014, the company announced 3G [UMTS](/source/UMTS) offering [HSPA+](/source/HSPA%2B) data services to all customers.<ref>{{cite web |url=http://www.telegeography.com/products/commsupdate/articles/2012/11/14/this-is-not-just-any-4g-this-is-tstt-4g/ |title=This is not just any '4G', this is TSTT '4G' |publisher=TeleGeography |date=2012-11-14 |accessdate=2014-08-13}}</ref>

Part of its 5-year strategy, bmobile refreshed its brand and announced a launch of [HD Voice](/source/HD_Voice) over its [3G network](/source/3G_network) as well as improved speeds by upgrading its existing [HSPA+](/source/HSPA%2B) network to support [DC-HSPA+](/source/DC-HSPA%2B). Days later, on December 9, 2016, the company went live with its [LTE network](/source/LTE_network) which, at the time of launch, was only available in [Port of Spain](/source/Port_of_Spain), [San Fernando](/source/San_Fernando%2C_Trinidad), and soon after, a few locations in [Tobago](/source/Tobago)  on  [LTE](/source/LTE_(telecommunication)) Band 2 (1900&nbsp;MHz).<ref name="TSTT 1900MHz TT">{{cite web |url=https://www.telegeography.com/products/commsupdate/articles/2016/12/12/tstt-launches-lte-in-1900mhz-band/ |title=TSTT launches LTE in 1900&nbsp;MHz band |publisher=TeleGeography |date=2016-12-12 |access-date=2016-12-12}}</ref> Service was launched on LTE Band 28 (700&nbsp;MHz) in October 2020 alongside the introduction of [LTE-A](/source/LTE-A).<ref name="bmobile 700MHz TT">{{cite web |url=https://bmobile.co.tt/covid-response/message-from-tstt/ |title=Message from TSTT |publisher=bmobile |access-date=2021-06-20}}</ref><ref>{{cite web |title=TSTT CEO shares insight on broadband expansion to internet security |url=https://newsday.co.tt/2021/07/08/tstt-ceo-shares-insight-on-broadband-expansion-to-internet-security/ |website=Trinidad and Tobago Newsday |date=2021-07-08}}</ref> 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](/source/Voice_over_LTE) services (VoLTE) were launched on January 29, 2025.<ref name="bmobile VoLTE TT">{{cite web |url=https://www.tstt.co.tt/news/bmobile-launches-volte-in-t%26t |title=bmobile Launches VoLTE in T&T |date=29 January 2025 |publisher=Telecommunications Services of Trinidad and Tobago |access-date=2025-02-01}}</ref>

In order for bmobile to do an LTE rollout however, the company decommissioned its [2G](/source/2G) [GSM](/source/GSM) 1900&nbsp;MHz network.

bmobile's parent company also purchased Massy Communications, now branded as AMPLIA,<ref name="Amplia">{{cite web |title=TSTT renames Massy as AMPLIA Communications with bmobile branding |url=https://www.commsupdate.com/articles/2017/12/05/tstt-renames-massy-as-amplia-communications-with-bmobile-branding/ |website=TeleGeography |access-date=10 August 2021 |date=5 December 2017}}</ref> a move which saw the company increase its market share against the Caribbean-heavyweights, [FLOW](/source/Flow_(brand)) and [Digicel](/source/Digicel). AMPLIA offers TV and fiber broadband services and also resells bmobile's landline and home security services.
