Staying connected in Hong Kong
Hong Kong has some of the densest 5G anywhere — full signal deep in the MTR, up the Peak tram and inside the towering malls.
Crucially, Hong Kong is NOT behind mainland China's Great Firewall, so Google, WhatsApp, Instagram and Gmail all work normally here.
The MTR Mobile app and Google Maps handle the excellent transit system, and both work the moment you land.
Everything you need in Hong Kong
Works on your phone
Almost every phone from the last few years supports eSIM. Not sure? Dial *#06# — if an EID number appears, you're good to go.
