1O1O

What 1O1O does

1O1O is Hong Kong's premium-tier mobile telecommunications brand, established in 1993 and operated by CSL Mobile Limited, a wholly-owned subsidiary of HKT Limited under the PCCW Group (HKEX: 6823). Headquartered in Hong Kong with 1,001–5,000 employees, the brand serves high-net-worth individuals and corporate leaders — claiming exclusivity with over 70% of Hang Seng Index listed companies — through a dedicated 5G network built on 3.3GHz/3.5GHz golden spectrum and validated by Ookla Speedtest Intelligence as the territory's fastest and most consistent 5G service. The product set spans the flagship 5G Prestige Service Plan, regional variants (Global, Asia Pacific, China–HK–Macau, C-level), an eSIM service supporting iOS, Android, Windows and smartwatch form factors, and a 24/7 personal concierge at 171010 that handles travel, dining, event and emergency requests.

The business model is subscription-centric, with tiered mobile plans locked into 12–36 month commitments and revenue streams across subscription airtime, usage-based data roaming (including category-first in-flight and cruise roaming passes sold via the AeroMobile and partner ecosystems), device and accessory sales of premium handsets from Apple, Samsung and Nothing, and a broad value-added services portfolio (MOOV 24-bit music, Microsoft 365, Xbox Game Pass, Blacknut cloud gaming, Netflix, Viu, iQIYI, Norton 360, Surfshark ONE, HKT Extended Warranty, home insurance and NFC mobile payment). Distribution is omnichannel — 1O1O Centers physical retail, the 1010.com.hk e-commerce storefront, a dedicated mobile app, customer service hotlines (2888 1010, 2988 1010), and the 171010 concierge line — supported by exclusive partnerships with over 100 luxury lifestyle brands, golf privileges via NOW TV and Hong Kong Golf Club, and Hong Kong Golf Open sponsorships. Recent product introductions include the AGENTICARE AI personal assistant (April 2026) and the 1O1O Tech AI Academy (2025), positioning the brand to migrate from pure connectivity provision toward AI-augmented lifestyle services for premium subscribers.
