Essential information to help you get connected seamlessly
This virtual SIM only includes data. It does not allow you to make cell phone calls or send SMS messages. You can still use WhatsApp or Skype to call your contacts.
Make sure your phone is both unlocked and compatible with eSIM technology.
Scan the QR code from your smartphone settings and add the data plan. You can either print it and scan it, or open it on another device to scan it. But don't activate it until you land at your destination.
No sales tax, one card for the whole city, and a border to mainland China that is its own trip
Hong Kong is simple in ways that surprise people. There is no sales tax, so the marked price is the price you pay. One stored-value card runs the trains, buses, ferries and the corner shop. And most visitors need no visa. The catch is the one people forget: Hong Kong is separate from mainland China, so being allowed into Hong Kong says nothing about crossing the border to Shenzhen, which is a different country's immigration and a different internet. This guide covers the money, the transport card, the entry rules, that border, and why data matters here.
The Star Ferry across the harbour
The Star Ferry has crossed Victoria Harbour between Hong Kong Island and Kowloon for well over a century, and it is still a working commuter service rather than a tourist boat, which is why it costs so little and feels so local. It gives the best cheap view of the skyline, and your stored-value transport card taps straight through the gate.4
Our take: ride it after dark when the towers are lit, and sit on the lower deck for the closest view of the water. It is one of the few world-famous experiences anywhere that still costs a couple of coins.
One Octopus card runs the city
The Octopus is a rechargeable contactless card you tap on the MTR, buses, trams and ferries, and it also pays at convenience stores, supermarkets and cafes across tens of thousands of points. It works offline, so you just tap and go, and you buy and top it up at any MTR station counter or convenience store, which makes it the one thing to sort first.2
Our take: buy an Octopus on arrival and lean on the MTR, which reaches almost everywhere a visitor goes and skips the traffic. The card doubling as a shop wallet means you can travel with very little cash at all.
There is no sales tax, and the currency is the HK dollar
Hong Kong is a free port with no sales tax, VAT or GST, so the price on the tag is the price you pay, with duties applied only to a few goods like alcohol and tobacco. Prices are in Hong Kong dollars (HKD), and cards, mobile payments and the Octopus are accepted almost everywhere, so you need little cash beyond a few notes for market stalls and older cha chaan teng cafes.3
Most visitors enter visa-free
Nationals of around 170 countries and territories can visit Hong Kong without a visa, for a stay ranging from 7 to 180 days depending on passport, and visitors are expected to hold an onward or return ticket. Hong Kong runs its own immigration as a Special Administrative Region, so you clear its border on arrival like any other.1
Hong Kong is not mainland China
Being admitted to Hong Kong does not let you into mainland China. The mainland has its own, separate immigration, so a trip across the border to Shenzhen or Guangzhou needs a Chinese visa arranged in advance, even though it is a short hop. Treat the crossing as an international one, not a domestic day trip.1
999 is the emergency number
In an emergency, 999 reaches police, fire and ambulance across Hong Kong, free from any phone, and 112 also connects from a mobile. English is widely spoken, including by operators and in most tourist-facing services, so getting help is straightforward.
Your Hong Kong data will not cover the mainland
Because Hong Kong and mainland China are separate jurisdictions, a Hong Kong SIM or eSIM does not carry over the border, and the mainland's internet is filtered in ways Hong Kong's is not. If your trip includes both, plan the mainland leg's connectivity separately rather than assuming one plan spans the two.
Hong Kong is outside every regional free-roaming arrangement, so a home plan roams here at a charge whatever your country, and a local eSIM keeps data at a predictable price on a fast, dense network with excellent coverage, including deep underground on the MTR. The catch is the border: a Hong Kong plan is for Hong Kong, and it does not extend into mainland China, which runs a separate network and a filtered internet, so a two-part trip needs its connectivity planned in two parts. Within Hong Kong itself you will lean on data constantly, for maps, translation, ride-hailing and the reservations a dense city runs on, while the Octopus handles the taps offline. Because the useful apps all assume a connection, getting data sorted before you land keeps the first hour simple. Set it up in advance, and if you are also visiting the mainland, arrange that side on its own.
Probably not for a short visit. Nationals of around 170 countries and territories can enter Hong Kong visa-free for between 7 and 180 days depending on passport, and you are expected to hold an onward or return ticket. Check the Immigration Department's list for your nationality and length of stay before you travel.1
No, not on your Hong Kong entry. Hong Kong is a Special Administrative Region with its own immigration, and mainland China is separate, so a trip across the border to Shenzhen or beyond needs a Chinese visa arranged in advance. Treat it as an international crossing rather than a domestic day trip, and plan the paperwork ahead.1
Use an Octopus card, a rechargeable contactless card that covers the MTR, buses, trams and ferries, and also pays at convenience stores and many shops. It works offline, you tap in and out, and you buy and top it up at any MTR station or convenience store. One card handles most of a trip, so get one on arrival.2
Usually not. Hong Kong is outside every regional free-roaming arrangement, so roaming on a home plan is billed whatever country you come from. A local eSIM keeps data at a predictable price, but note it covers Hong Kong only, not mainland China, so a trip across the border needs its own arrangement.
