Hong Kong’s real-name rules apply to visitors too: any prepaid SIM you buy must be registered to you before it works. You do not need a Hong Kong ID — your passport (or other valid travel document) is accepted.
Where to buy a tourist SIM
- Hong Kong International Airport — operator counters and vending machines in the arrivals area.
- Convenience stores (7-Eleven, Circle K) and personal-electronics shops across the city.
- Online before you fly — buy an eSIM and register it remotely, ready on arrival.
What you need
- Your passport or travel document (the same one you entered Hong Kong on).
- The SIM or eSIM you are activating.
How registration works
- If you buy in person, staff usually scan your passport and register the SIM for you on the spot.
- If you buy an eSIM online, follow the seller’s app: enter your passport details and upload a photo of the passport.
- Once verified you receive the eSIM QR code or activation confirmation, and data starts working.
Buying an eSIM before you travel is the smoothest option: you register at home, skip the airport queue, and have working data the moment you land.
Alternatives to a local SIM
If you only need data for a few days you can also use international roaming on your home plan, or rent a pocket Wi-Fi — neither requires Hong Kong registration, though a local prepaid SIM or eSIM is usually cheaper for anything more than a short trip.

Yes. Non-residents register with a valid passport or travel document — a Hong Kong ID card is not required.
Can I buy a registered SIM at Hong Kong airport?
