TCT mobile ltd — 50 prefixes (MA-L)

TCT mobile ltd holds 50 IEEE MA-L blocks, all registered to the same address at No.86 Hechang 7th Road, Zhongkai Hi-Tech District, Huizhou, Guangdong, China. TCT Mobile is the mobile-devices arm of TCL Technology Group Corp., a Chinese consumer-electronics group headquartered in Huizhou and listed on the Shenzhen Stock Exchange; it ships consumer Android smartphones and mobile-broadband hardware (MiFi/hotspots) primarily under the Alcatel brand, and has at various points manufactured handsets under the licensed BlackBerry name (2016–August 2020) and the Palm brand. A device presenting a TCT Mobile OUI on a network is almost certainly a personal/BYOD consumer Alcatel- or TCL-brand handset or a portable hotspot, not enterprise networking gear or embedded IoT firmware. Each MA-L block spans roughly 16 million addresses, so the 50 prefixes cover on the order of 800+ million addresses in aggregate. As with every OUI vendor, IEEE publishes no registration date for these assignments: "First Seen" / "Last Mod" timestamps shown by third-party lookup tools are database artifacts, not IEEE-assigned dates, and must not be presented as registration or founding dates. Two sourced security notes are worth flagging for analysts but neither targets TCT Mobile's MAC-layer hardware directly: the Texas Attorney General sued TCL in December 2025 over alleged viewer-data sharing (that action concerns TCL's smart-TV division), and security researchers circa 2019–2020 reported pre-installed adware/billing-fraud behavior in bundled apps on some Alcatel handsets (no direct-URL source could be confirmed this pass — treat as Likely).

Security note

Texas AG sued TCL (Dec 2025) over alleged viewer-data sharing with the Chinese government (TCL smart-TV division, not TCT Mobile handsets) [Likely] — https://en.wikipedia.org/wiki/TCL_Communication. Pre-installed adware/billing-fraud reported on some Alcatel Android phones circa 2019–2020; no direct-URL source confirmed this pass

[Likely] — research-pass note, unverified URL

Analyst note

a TCT Mobile OUI on a globally-administered address identifies a consumer Alcatel/TCL handset or hotspot; no enterprise/IoT association. Modern Android handsets also use MAC randomization on Wi-Fi, so absence of this OUI does not mean "not TCL."
