Going on to the mainland?
A plan that covers only Hong Kong won’t help once you cross. See our China SIM with a Hong Kong number, or the China SIM and eSIM comparison.

Quick answer: For most visitors, an eSIM installed before you fly is the simplest way to get data in Hong Kong. If your phone doesn’t support eSIM, order a physical SIM online or buy one in the city, and bring your passport. If your trip continues to the mainland, check the plan’s coverage first. If you need a Hong Kong phone number as well, our Hong Kong number service offers a virtual number, or a SIM or eSIM with a number.
A Hong Kong SIM card, often called an HK SIM card, comes as an eSIM or a physical card. Pick an eSIM if your phone supports it and you want data on arrival. Pick a physical SIM if it doesn’t, or if you’d rather hold the card in your hand. Buying in the city works if you don’t mind a stop at a shop. Only the mainland changes the choice, because many Hong Kong plans stop at the border.
Holafly sells a Hong Kong eSIM with unlimited data. It is data only, with no local phone number or SMS, and coverage can be weaker in country parks and on outlying islands. Install it before you fly and switch it on when you land. Check the plan page for current prices and terms, and use the compatibility checker to confirm your phone supports eSIM. If you also need a Hong Kong phone number, see the number options below.
See the Hong Kong eSIMNeed a real Hong Kong mobile number? Our own Hong Kong number service offers a physical SIM or an eSIM with a Hong Kong number, ordered through WeChat. Start with a number, then upgrade it to a SIM or eSIM. Plans and current prices are on the Hong Kong number page.
See the Hong Kong number serviceA virtual Hong Kong number receives SMS and calls without a SIM card, which suits Hong Kong app and website sign-ups and verification codes. You can upgrade it to a SIM or eSIM later.

View on AmazonPrepaid SIMs are sold in the city at carrier shops and other stores. Bring your passport, because the SIM must be registered with your ID, and ask what the visitor plan includes. It takes time on arrival, but you can compare plans in person.

Not strictly. Wi-Fi is easy to find in hotels and cafés, but a data plan keeps maps, translation and messaging working between stops. An eSIM can be installed before you fly, while a physical SIM needs a swap on arrival.
Choose an eSIM if your phone supports it and you want data working the moment you land. Choose a physical SIM if your phone is older or you prefer to buy one in person. The compatibility checker below shows whether your phone supports eSIM.
Yes. Holafly’s Hong Kong eSIM is sold with unlimited data, and it is data only, with no local phone number or SMS. Other plans, including prepaid SIMs, may have data caps or speed limits, so read the listing before you buy.
An unlocked phone and your passport. Hong Kong requires real-name registration for SIM cards before they can be activated, using your own original ID document, and visitors without a Hong Kong ID card register with their passport. Providers offer different registration channels, such as online or in a shop. Don’t buy a pre-registered SIM from unknown sellers.
It depends on the plan. Holafly’s Hong Kong eSIM covers Hong Kong only, and it sells a separate Hong Kong, Macau and China plan for wider trips. Other plans differ, so read the coverage line before you buy. If your trip includes the mainland, see our China SIM with a Hong Kong number.
Many visitor data plans are data-only. Holafly’s Hong Kong eSIM, for example, includes no local phone number or SMS. If you need a Hong Kong number for calls, SMS or verification codes, our Hong Kong number service offers a virtual number, or a physical SIM or eSIM with a Hong Kong number. To call Hong Kong or dial out, see our Hong Kong country code and dialing guide.
Yes. Start with a Hong Kong number through our Hong Kong number service, ordered with the eSender official account on WeChat, then upgrade it to an eSIM or a physical SIM. You need a WeChat account to order.
Yes. A Hong Kong virtual mobile number receives SMS in WeChat or an app without a SIM card, and it can make and receive calls through an app. It suits Hong Kong app and website sign-ups, but check each service’s own rules before relying on it.
No. Hong Kong doesn’t use the mainland firewall, so Google, WhatsApp and most Western apps work normally there. A VPN only becomes relevant if you go on to the mainland.
China Mobile Hong Kong (CMHK) is China Mobile’s Hong Kong operator, with its own Hong Kong plans. A mainland China Mobile SIM and a Hong Kong SIM are separate products, so check which one a plan uses before you buy.
