Practical notes for Hong Kong
- Coverage holds underground on the MTR and on the ferries; hiking trails on Lantau and in the New Territories can be patchy.
- The Octopus card and most restaurant bookings live in apps; a short plan covers a city break comfortably.
- Continuing to Shenzhen or the mainland? That needs a China plan — Hong Kong plans stop at the border.
How to get connected
- Download Num and pick Hong Kong.
- Choose a plan and pay with Apple Pay.
- Scan the QR code the app gives you — Settings → Cellular → Add eSIM.
- Turn on data roaming for the Num line when you land.
Questions about Hong Kong
How much does an eSIM for Hong Kong cost?
Plans start at $3.20. The table on this page shows current prices — 14 options ranging from short trips to month-long stays. These are the prices you pay in the app; there are no separate activation or delivery fees.
Will my phone work with a Hong Kong eSIM?
Most iPhones from the XR and XS onward support eSIM, and the handset must be carrier-unlocked. Check the compatibility page for the full list before you buy.
When does the plan start counting down?
Validity begins when the eSIM first connects to a network in the coverage area, not when you buy it. You can install it before you travel and it will wait until you land.
Can I keep my normal number while using it?
Yes. The Num eSIM runs alongside your existing SIM, so calls and texts on your usual number keep working while data runs over the travel plan. Turn your normal line's data roaming off to avoid a roaming bill.
Can I add more data if I run out?
Yes — reloadable plans can be topped up from inside the app without buying a new eSIM or reinstalling anything.
Is there an unlimited data eSIM for Hong Kong?
Num does not sell unlimited plans for Hong Kong. The closest are the daily-allowance plans, such as 3 GB per day, which give a fixed amount each day for the length of the trip. For most travellers the fixed bundles, from 500 MB to 50 GB, are better value.
Which networks does a Num Hong Kong eSIM use?
It connects to 3, csl, csl/1010 and SmarTone and picks the strongest available network automatically. 13 of the 14 plans support 5G; the rest run on 4G/LTE.
Do I get a Hong Kong phone number with the eSIM?
No. Num eSIMs are data-only. Your own number stays active on your existing SIM for calls and texts, and WhatsApp, iMessage and other messaging apps keep working over the eSIM's data. If you need a local number, see our guide to eSIMs with a phone number.
What is the best eSIM for Hong Kong?
It depends on how long you stay and how much you use maps and video. On this page the best value per gigabyte is 10 GB per day for 1 day at $9.43 ($0.94); the trip-length picks match a plan to a weekend, a week, two weeks and a month.
