Can I use the internet the moment I reach the airport in Sri Lanka?

Yes! If you install your Yeohaengyusim eSIM before departure Korea, it links up automatically with the Dialog network the moment you arrive at Bandaranaike International Airport. You don't need to queue at the airport SIM shop, so you can set off straight after you enter the country.

Does the internet work at remote destinations such as Sigiriya and Udawalawe?

Sri Lanka's 4G/LTE coverage is about 78%, and the connection is reliable at the main sights and in urban areas. However, coverage can be patchy or drop out deep inside national parks or in remote mountain areas. Downloading offline maps in advance gives you extra peace of mind.

Are the outlets in Sri Lanka a different type? Will I have any trouble charging?

Sri Lanka uses Type D, Type G and Type M outlets. They are different from Korea's Type C/F, so you definitely need a separate adapter. Pack a multi-adapter before departure. Upmarket hotels sometimes have universal outlets, so it is also a good idea to check with your accommodation in advance.

Can I use Google Maps while travelling in Sri Lanka?

Yes, Google Maps works well. However, map information may be inaccurate for some small towns and back streets in Sri Lanka. If you also use Maps.me or Google Maps' offline area download feature, finding your way is much easier even in areas with a weak internet connection.

Which season suits a trip to Sri Lanka?

The monsoon season differs from region to region in Sri Lanka. On the west and south coasts (Colombo, Galle), December–March is the dry season and a good time to travel, while on the east coast (Trincomalee, Arugam Bay) May–September is clear and sunny. The central highlands are cool all year round but rain is frequent, so bring waterproof gear.

Does eSIM work in Sri Lanka?

Sri Lanka supports eSIM, and plans start from ₩4,053. 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 Sri Lanka?

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 Sri Lanka eSIM use?

In Sri Lanka it connects automatically to local carrier networks such as Dialog · Mobitel · Hutch (4G/LTE, 5G where supported). Population coverage is about 78%. 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 Sri Lanka?

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 Sri Lanka 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.

Can I use tethering (hotspot) in Sri Lanka?

Yes. In Sri Lanka you can share your eSIM data with other devices such as a laptop or tablet by tethering (hotspot). Shared data also comes out of your plan allowance, so if you tether a lot we recommend choosing a little more data.

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 Sri Lanka. Just remember "set up before you leave, switch on when you arrive" and you can use the internet as soon as you land.

Known as the teardrop of the Indian Ocean, Sri Lanka is a mystical island nation where an emerald sea, lush tropical rainforest and ancient Buddhist ruins come together. From the jungle views you look down on from the Sigiriya rock fortress to the Temple of the Tooth in Kandy and Udawalawe National Park, where wild elephants roam, there is no shortage of things to see. A few hours' drive from Colombo, you can breathe the most fragrant air in the world on a black tea plantation up in the hills. To fully enjoy such a varied destination, an internet connection that does not drop out even on the move is a must. To find remote destinations on Google Maps, get help from a translation app when haggling over prices with rickshaw drivers and post the photos of a lifetime straight to social media, a single Yeohaengyusim eSIM is all you need. Just install it before departure, with no worries about swapping SIMs, and it connects automatically right after landing at Colombo airport.

Why an eSIM really helps for a trip to Sri Lanka

Travel in Sri Lanka often means moving back and forth between cities and the countryside. From big cities such as Colombo to the tea-growing area of Nuwara Eliya, the coastal town of Galle and national parks deep in the jungle, distances are long and routes are complicated. With this kind of travel, Google Maps navigation and real-time traffic information are practically a lifeline. If you buy a SIM at the local airport, you have to queue, and the language barrier is no small matter either. A Yeohaengyusim eSIM, on the other hand, is bought in advance through the app in Korea and installed with a QR code, and the internet comes on as soon as you step off the plane. It runs on the Dialog network, provides about 78% coverage across Sri Lanka and is comfortable to use at 4G/LTE speeds. You keep your existing Korean SIM as it is and just activate the eSIM alongside it, so you won't miss calls to your Korean number either. It is a connectivity solution that fits perfectly with the Sri Lankan style of travel, visiting several religious sites and natural attractions in a single day.
