eSIM or a local SIM at the airport in Guinea-Bissau?
An eSIM is ready before you land. No queue, no shop, no handing over your passport at a counter. Data for Guinea-Bissau starts at $16.06 on this page, which is hard for airport kiosks to beat. A local SIM still makes sense if you need a local phone number or plan to stay for months. For a normal trip, the eSIM wins on price and effort.
Setting up your Guinea-Bissau eSIM
Buy your planYou get a QR code by email within minutes of paying.
Install before you flyScan the QR code on wifi at home. Airport and hotel wifi can be weak.
Turn it on when you landEnable the eSIM and turn on data roaming for it, then give it a minute to find the network.
Check the validity clockSome plans start counting at purchase, not at first use. Check before you buy.
Good to know before you land in Guinea-Bissau
Official shops ask for a passport when you register a SIM, and some also want a local address such as your hotel.
MTN and Orange branded booths sell SIM cards in the arrivals terminal at Osvaldo Vieira International Airport in Bissau. Airport stands carry fewer plans and higher prices than city shops, and vendors also wait just outside the building.
Pick Orange if you want the widest coverage and the cheapest data. Download maps and anything important before heading to the Bijagos islands, since data there is unreliable.

Can I top up my Guinea-Bissau eSIM if I run out?
Yes. 11 of the 11 plans here support top ups, so you can add data without buying a new eSIM. The rest need a fresh plan once the data ends.
Will I still receive bank SMS and OTP codes?
Yes, if you keep your home SIM active. Travel eSIMs are data only. Your phone can hold both at once, so leave your normal SIM on for SMS and use the eSIM for data. Turn off roaming data on the home SIM to avoid charges.
Do these eSIMs include a phone number or calls?
The plans we compare are data only, so there is no local number. Calls work fine over WhatsApp, FaceTime, or any app that uses data. If you need a real local number, a local SIM is the better tool.
