Do I really need data to use Bitcoin payment apps in El Salvador?

Yes, that's right. El Salvador was the first country in the world to adopt Bitcoin as legal tender, and an internet connection is essential to use the official payment app, Chivo. With data secured through your eSIM, you can make digital payments smoothly anywhere, whether in cafés, supermarkets or taxis.

Does data work at surf spots like El Sunzal beach and La Libertad?

On the Tigo and Claro networks, 4G/LTE generally works well in the main beach towns of El Sunzal and La Libertad. However, overall coverage is around 70%, so the signal may weaken on remote beaches or in mountainous backcountry. We recommend saving important information offline in advance.

Can I use the eSIM while trekking Santa Ana Volcano?

Near the summit of the volcano or deep in the mountains, coverage can be patchy or drop out. It pays to download offline maps (Maps.me, or Google Maps saved offline) before your trek. In the villages near the start and end points, a 4G connection is available.

Can I install the El Salvador eSIM before leaving Korea?

Yes. A Yeohaengyusim eSIM can be installed by QR code as soon as you buy it. Install it in Korea in advance, activate the data plan after you arrive, and you can use it from the moment you walk out of the airport. No need to go hunting for a local SIM.

Can I leave my Korean SIM card in and use the eSIM separately when travelling in El Salvador?

That's right. If your smartphone supports eSIM, you don't need to take out your Korean SIM card. You keep your Korean number while using the eSIM for local data, which is very convenient. To check whether your device supports eSIM, look under 'Cellular' or 'SIM card' in your device settings.

Does eSIM work in El Salvador?

El Salvador supports eSIM, and plans start from ₩4,355. 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 El Salvador?

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 El Salvador eSIM use?

In El Salvador it connects automatically to local carrier networks such as Tigo · Claro · Movistar (4G/LTE, 5G where supported). Population coverage is about 70%. 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 El Salvador?

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 El Salvador 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 El Salvador?

Yes. In El Salvador 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.

How many GB of data do I need for a trip to El Salvador?

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.

El Salvador, a hidden gem of Central America, is a captivating place where surf culture, volcano trekking and ancient Maya ruins exist side by side, living up to its nickname 'the country of the Beatles'. From trekking El Cungo volcano and the world-class surf spot of El Sunzal beach to the lively streets of San Salvador's old town, there is no end of things to see and do. But it is such a long way from Korea that the local mobile environment is unfamiliar, and getting a SIM card in the arrivals hall is not easy either. Get your Yeohaengyusim eSIM ready before departure and you can use map and translation apps freely from the moment you set foot in San Salvador airport. On an unfamiliar trip to Central America, data is one thing you need not worry about.

Why you really need an eSIM in El Salvador

El Salvador is one of the top surfing paradises in Central America. In beach towns like El Sunzal and La Libertad, it is not easy to find somewhere selling local SIMs. With a Yeohaengyusim eSIM, you can install it in Korea in advance and connect automatically to the Tigo or Claro 4G/LTE network as soon as you step off the plane. In particular, El Salvador has adopted Bitcoin as legal tender, so there will be times when you need to use digital payment apps and cryptocurrency wallets frequently. Without a stable data connection, payment itself may be impossible, which makes the eSIM's role even more important. Even while trekking in the volcano national parks, using Google Maps together with offline maps means you need not worry about getting lost. You don't need to swap SIM cards, and it installs easily with a single QR code, so you can focus on your trip without any complicated steps. With Yeohaengyusim, you are connected anywhere in El Salvador.
