Can I use the internet the moment I reach Hong Kong airport?

Yes. If you install a Yeohaengyusim eSIM before departure Korea, it links up automatically with the local network right after landing at Hong Kong International Airport (HKIA). With no need to find a SIM counter or queue, you can open Kakao Map or Google Maps right away as you walk out of the arrivals hall.

Does data work well on the Hong Kong MTR too?

The Hong Kong MTR is famous for good LTE and 5G reception, even in its underground sections. A Yeohaengyusim eSIM uses the CMHK and CSL networks, so you can use data reliably while travelling on the MTR. It stays connected without interruption even as you go back and forth between the Kowloon Peninsula and Hong Kong Island, making it a perfect fit for travel mainly by public transport.

What happens with the eSIM if I travel to Hong Kong and Macau together?

A Hong Kong-only eSIM may not work in Macau. If you plan to travel to both Hong Kong and Macau, it is best to choose an Asia-wide regional eSIM plan that covers both, or to get a separate eSIM for Macau as well. Be sure to check the plan's coverage before you buy.

Will I need a power adapter in Hong Kong?

Yes. Hong Kong uses Type G outlets, for British-style square three-pin plugs. They differ from Korea's Type C (two round pins), so you need a separate adapter. You can also buy one at Hong Kong airport or in convenience stores, but we recommend packing one in Korea before you go.

Can I use a hotspot (tethering) with a Hong Kong eSIM?

Yes, most Hong Kong eSIM plans support hotspot tethering. You can share your data with a laptop or tablet. However, tethering may be restricted on some low-cost plans, so check the plan description before you buy.

Does eSIM work in Hong Kong?

Hong Kong supports eSIM, and plans start from ₩5,259. Install it with the QR code you receive after buying, then just turn on data roaming after you arrive and you are connected straight away. There is no need to swap your SIM.

Travel eSIM or carrier roaming: which is cheaper for a trip to Hong Kong?

For a short trip or light data use, a travel eSIM is usually cheaper. Unlimited roaming from Korean carriers costs about ₩11,000–₩15,000 a day, but with an eSIM you can buy just the days of data you need in advance. For a short trip for one or two people, an eSIM has a big advantage; for a family or very heavy data use, compare carrier unlimited roaming too.

Which carrier network does a Hong Kong eSIM use?

In Hong Kong it connects automatically to local carrier networks such as CMHK · CSL · SmarTone · 3 Hong Kong (4G/LTE, 5G where supported). Population coverage is about 99%. It picks the network with the strongest signal automatically, so there is nothing to set up.

Can I keep using my Korean number while travelling in Hong Kong?

Yes. The eSIM works as a data-only second line, so your Korean SIM and number stay as they are. Use the Yeohaengyusim eSIM for data only, and keep receiving calls, texts and KakaoTalk on your Korean number.

Can I add to or extend my Hong Kong eSIM plan?

Yes. When you use up your data or the plan period ends, you can buy a new plan at any time. Keep using the eSIM profile you already installed; there is no need to install it again, so you carry on without interruption.

Do I set up the eSIM before I leave or after I arrive?

We recommend installing it (registering the QR code) before you leave, while you have Wi-Fi. Data starts when you turn on data roaming after you arrive in Hong Kong. Just remember "set up before you leave, switch on when you arrive" and you can use the internet as soon as you land.

How many GB of data do I need for a trip to Hong Kong?

For mostly maps and messaging, we recommend about 1 GB a day; to use plenty of social media and photo uploads, about 2 GB a day. If you stream a lot of video or tether a lot, an unlimited plan is better. You can always buy more if you run short, so it is fine to choose a little extra at first.

Hong Kong, the city where East meets West, is always an exciting destination for Korean travellers. From Victoria Peak and its beautiful night view to back-street restaurants overflowing with dim sum and wonton noodles, and the shopping paradises of Mong Kok and Tsim Sha Tsui, it is a city that packs a full experience into even a short trip. You can get there from Incheon in about 3 hours 30 minutes by plane, so it is also popular for weekend trips. Hong Kong is a destination you enjoy by moving around every corner of it, so smartphone internet is essential, from checking metro lines to searching for good places to eat and getting real-time directions. With no need to queue at the airport to buy a local SIM or to pay expensive roaming charges, you can finish all your preparations before departure with just a Yeohaengyusim eSIM. Enjoy fast data as much as you like from the moment you set foot in Hong Kong.

Why an eSIM really helps for a trip to Hong Kong

Hong Kong is one of the world's leading smart cities, with a dense 5G network across the whole urban area. Through local carrier networks such as CMHK and CSL, it boasts coverage of as much as 99%, from Hong Kong Island and the Kowloon Peninsula to the New Territories. In Hong Kong in particular, the standard way to travel is to make full use of public transport such as the MTR, trams and the Star Ferry, so a stable data connection is a must if you want to check maps and transport information without interruption while on the move. If you install a Yeohaengyusim eSIM with a QR code before departure Korea, it links up automatically with the local network the moment you arrive at Hong Kong International Airport. You don't need to swap SIM cards or wait at an airport counter, so you save time from the very start of your trip. Also, in Hong Kong the security of public Wi-Fi in accommodation and cafés is often weak, so using your own data is much safer. Enjoy Hong Kong more smartly with an eSIM that keeps a stable speed even in crowded places such as concerts, night markets and night-view spots.
