Why Hong Kong is different
"Hong Kong's MTR subway system has had continuous 4G in every station and in every tunnel since 2018 — unique among Asian metros of its size."
Hong Kong has the highest 5G tower density of any major Asian city and some of the fastest measured mobile speeds in the world. CSL, SmarTone, and 3HK all offer genuinely competitive urban 5G. The hidden win for tourists: Hong Kong's free Wi-Fi network "Wi-Fi.HK" is one of the best in the world.
Our Hong Kong plans use CSL primarily. CSL has the best coverage in the MTR subway, in the Victoria Harbour tourist core, and on the outer islands (Lantau, Lamma).
Coverage you can actually measure.
We run Hong Kong on 2 carriers so your profile falls back automatically if one signal drops. Coverage figures are measured against our own uptime data, not carrier marketing claims.

Troubleshooting
- MTR has full cellular coverage in every line including underwater harbor crossings.
- Some SAR rural areas (Sai Kung country parks) have CSL-only coverage.
- Hong Kong and Macau are separate — do not assume a Hong Kong plan covers Macau.
