Do I need a visa for Guinea-Bissau?

Yes, Korean passport holders need a visa to enter Guinea-Bissau. In some cases a visa on arrival is possible, but to be safe, be sure to check the latest visa policy before departure, through a Guinea-Bissau embassy in a neighbouring country or through official channels.

Does the eSIM connect as far out as Guinea-Bissau's Bijagós Archipelago?

The Bijagós Archipelago is made up of remote islands far from the Guinea-Bissau mainland. Coverage is currently concentrated mainly in major mainland cities such as Bissau, so on some islands of the Bijagós Archipelago coverage can be patchy or it may be hard to connect. Before travelling to the islands, we recommend downloading plenty of offline maps and information in advance.

What should I be most careful about when travelling in Guinea-Bissau?

Security in Guinea-Bissau tends to be unstable. Be sure to check the latest travel alert level on the Ministry of Foreign Affairs' Overseas Safety Travel website. Vaccinations against tropical diseases such as malaria and insect repellent are also essential. ATMs are rare there, so it is also important to bring enough cash (West African franc, XOF).

Can I also make calls in Guinea-Bissau?

Yeohaengyusim eSIMs are data-only plans. Local phone calls and texts are not supported. However, while connected to data, you can use internet-based messengers such as KakaoTalk and WhatsApp, and internet calls (VoIP). If you keep your existing SIM, you can still receive calls to your Korean number as usual.

Which season suits a trip to Guinea-Bissau?

The dry season, from November to May, is the best time to travel. December–February in particular is cool with almost no rainfall, so getting around is easy. June–October is the rainy season, with heavy rain and road conditions that worsen and make getting around difficult, so it is best to avoid it if you can.

Does eSIM work in Guinea-Bissau?

Guinea-Bissau supports eSIM, and plans start from ₩5,861. 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 Guinea-Bissau?

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 Guinea-Bissau eSIM use?

In Guinea-Bissau it connects automatically to local carrier networks such as MTN Guinea-Bissau · Orange Bissau (4G/LTE, 5G where supported). Population coverage is about 35%. 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 Guinea-Bissau?

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 Guinea-Bissau 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 Guinea-Bissau?

Yes. In Guinea-Bissau 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 Guinea-Bissau. Just remember "set up before you leave, switch on when you arrive" and you can use the internet as soon as you land.

Guinea-Bissau, a hidden gem of West Africa, is still an unfamiliar destination for most Koreans. Centred on Bissau, it is a place where streets that still bear traces of the Portuguese colonial era coexist with the untouched nature of the Bijagós Archipelago and its dense mangrove forests. With its secluded beaches and rich variety of ecosystems, the country offers a special experience to adventurers who dream of true off-road travel. Because local infrastructure is poor, thorough preparation before your trip is essential, and as mobile connections in particular are unreliable, installing a Yeohaengyusim eSIM in Korea before you go is a wise choice. Carry on your journey safely with just your smartphone, with no need to swap SIM cards.

Why you really need an eSIM in Guinea-Bissau

Even by West African standards, Guinea-Bissau is a country where telecoms infrastructure has been slow to develop. To buy a local SIM, you have to visit a carrier's shop in central Bissau in person, but opening hours are irregular and communicating in English is not easy, so you can waste a great deal of time and energy. A Yeohaengyusim eSIM, on the other hand, if you install it before departure Korea, connects automatically to the MTN Guinea-Bissau network as soon as you enter Guinea-Bissau, so you can use it right away. Coverage is around 35% and concentrated mainly in Bissau and a few major cities, so the signal may weaken once you leave the big cities, but it is quite enough for map apps on the move and for emergency contact. Above all, when you travel in remote areas, it lets you tell family and friends that you are safe whenever you are in an area with internet, which makes an eSIM a necessity rather than an option. You can also keep your existing Korean number without swapping a physical SIM, which is an advantage for emergency contact.
