Choose a Hong Kong eSIM with the data allowance and validity period that suit your trip. Plans are available for stays from one day to 180 days, including unlimited-data options.
Coverage & networks
The eSIM connects to csl and SmarTone 5G networks in Hong Kong. It is data-only, so calls and text messages are not included.
How much data you need
Choose from allowances of 0.1GB, 0.5GB, 1GB, 3GB, 5GB, 10GB, 20GB or 50GB. Unlimited-data plans are also available. If you need more data during your trip, you can top up your eSIM rather than buying a new plan.
Setting it up
Select the validity period that matches your stay, from one day to 180 days, then install and activate your eSIM for use in Hong Kong. As the plan does not include calls or texts, use data-based messaging and calling services if needed.
