No SIM swap, no sign-up

Real Hong Kong networks
Travel eSIMs ride CSL, 3 and SmarTone, so you get genuine local coverage across the city, the MTR and the islands.
Cheaper than roaming
A prepaid Hong Kong eSIM costs a fraction of home-carrier roaming, and a promo code trims the price further.

Staying connected across Hong Kong
Hong Kong runs on data: tapping through the MTR, hailing a taxi, paying with Octopus or a wallet app, and navigating from Central to Kowloon all expect you to be online. A travel eSIM gives you that from the moment you land, on the same networks locals use.
- CSL: the widest, fastest 4G/5G coverage, strong city-wide and in the MTR tunnels
- 3 (Three): reliable speeds across Hong Kong Island and Kowloon with good value plans
- SmarTone: a solid alternative with strong central and harbour-front coverage

Hong Kong eSIM FAQ
- Which is the best eSIM for Hong Kong?
- It depends on how long you stay and how much data you use. For a short city trip a few gigabytes is plenty, while a longer stay or heavy hotspot use is simpler on an unlimited plan. Compare the price per GB and the local network in the tool above, then add a promo code before you buy.
- Will an eSIM work everywhere in Hong Kong?
- Yes. Travel eSIMs ride Hong Kong's major networks (CSL, 3 and SmarTone), and the city has some of the densest, fastest 4G and 5G coverage anywhere, from the airport and the MTR tunnels to Victoria Peak and out to the islands.
- Do I need ID to use an eSIM in Hong Kong?
- No. Buying a local prepaid SIM in a shop can involve showing your passport, but a travel eSIM is bought online before you arrive and activates instantly by QR code, with no paperwork and no queue at the airport.
