Before you go
Travelling in Hong Kong (China)
How much data do you need in Hong Kong (China)?
Maps, messaging, ride apps and a few photos use about 300 to 500 MB a day, so 1 GB covers a short stay and 3 to 5 GB a week of normal use. The smallest plan is 500 MB · 7 days for $1.10; a longer trip is cheaper per gigabyte on a bigger plan. For video calls, streaming or a hotspot for a laptop, unlimited daily data starts at $1.24 a day. Most plans top up from your order page if you run low.
Where travellers use it
Most of our customers land in Hong Kong and Kowloon and travel on to Lantau and Macau. Coverage follows the operator’s network, so a city centre, an airport and a main road are covered everywhere; remote coast and mountains depend on the plan’s operator.
eSIM or a local SIM card in Hong Kong (China)?
Hong Kong requires real-name registration for every local SIM card since 2023, so airport SIMs now mean a passport and a form. A travel eSIM needs no registration and runs on the same 5G networks from the Airport Express onwards.

Need broader coverage?
These multi-country eSIMs include Hong Kong (China) and keep working when you cross a border.
Why an eSIM
Why use an eSIM in Hong Kong (China)?
Landing in Hong Kong (China) with data already working means maps, translation and your ride from the airport are ready before you reach the exit. No kiosk, no passport photocopy, no hunting for Wi-Fi.
Your home SIM stays in the phone for calls and texts. The eSIM handles data on local networks, so you avoid roaming bills without losing your number.
Install on Wi-Fi at home and keep the line switched off until you land. Validity starts the first time it connects abroad, not when you buy.
How our Hong Kong (China) prices compare with Airalo, Holafly, Saily and Nomad →Good to know
How much does an eSIM for Hong Kong (China) cost?
Plans start at $1.10 for 500 MB · 7 days. Unlimited daily data costs $1.24 a day (the first 500 MB each day at high speed, then 512 Kbps under the fair use policy). Prices are in US dollars and include everything: no roaming fees, no subscription.
When does my Hong Kong (China) plan start?
On nearly every plan, the first time the eSIM connects to a network abroad, not when you buy or install it. A few plans start on installation; each plan says which. Install within 180 days of purchase.
Do I need to change any settings?
Turn the travel line on, enable data roaming for that line only, and set it as your mobile data line. Keep data roaming off on your home line. Most phones set the APN automatically. If you are connected but have no data, enter the APN shown on your order page or eSIM page (none shown means the phone sets it itself), or reply to your order email and we will help.
How fast is it?
Each Hong Kong (China) plan lists its operators and whether they run 3G, 4G or 5G; each plan card shows its best generation. Daily unlimited plans slow to the fair-use speed shown on the plan once the day's full-speed data is used.
Can I top up or buy again?
Most plans can be topped up from your order page, with more data for the same area or more days. Plans marked non-reloadable cannot; buy a new one and it installs the same way.
Is tethering allowed?
Yes, personal hotspot works on every plan.
Does a Hong Kong plan also cover Macau and Shenzhen?
No, Hong Kong only. For a day trip to Macau or mainland China, choose the China, Hong Kong and Macao plan under broader coverage above; it keeps the unfiltered Hong Kong routing on the mainland.
Is the internet filtered in Hong Kong?
No. Hong Kong networks are not behind the mainland filters; Google, WhatsApp and every app work as at home, on the eSIM or any local SIM.
