Choose Guinea-Bissau eSIM data around a Bissau arrival, an inland family or work visit near Bafatá, or a separately arranged Bijagós stay. Match validity to all confirmed travel days and ask about the service area for any island address.
Guinea-Bissau combines a mainland journey with an archipelago that needs its own transport planning. Bissau is the capital and airport gateway; Bafatá is an inland destination to the east, while Bubaque is an island and town in the Bijagós. A visit split between these places involves more than changing accommodation. Rural roads, tidal waterways and sea crossings can separate the opportunities to connect. Prepare work or family arrangements offline and check official government travel advice before committing to the itinerary.
Refund policy
We always refund the full amount you paid when you request it, whether your eSIM is unused, partly used or fully used. There is no time limit for requesting a refund.
No first-use deadline
Validity does not start until your eSIM connects to a supported network at your destination. There is no deadline for first use. You can buy now and keep your plan for a future trip.

Install the Guinea-Bissau profile over Wi-Fi on a phone that is both eSIM-compatible and carrier-unlocked. Before an Osvaldo Vieira International Airport arrival, save the Bissau pickup and the first address your host expects you to reach. After entering Guinea-Bissau, select the travel profile for mobile data and enable its roaming as the order instructs. Installing the profile does not start the validity period; it starts when the eSIM first connects to a supported network in Guinea-Bissau. For a later island transfer, store the organiser's meeting point, arrival arrangement and return details before boarding.

Pick the profile closest to your trip. The estimate assumes normal use — maps, messaging, photos, a short call home.
As a rule of thumb, a 3–4 day city break runs on about 1–3 GB, a one-week trip on 3–5 GB, a two-week multi-country tour on 8–12 GB, and working on the road takes about 1 GB a day, so 15 GB or more for two weeks.
In total, a 3 GB data allowance covers roughly 1,000 shared photos, 50 hours of social media and browsing, 8.8 hours of video calls, 38 hours of music streaming, or about 600 hours of maps and navigation. Messaging apps barely use data.
Bissau · City guide
Bissau is the starting point for many work and family visits, served by Osvaldo Vieira International Airport. Keep your lodging or office entrance separate from any harbour meeting point for an onward trip. Confirm the actual boarding location with the organiser rather than selecting the nearest waterfront pin.
Bissau eSIM — set up before you flyBafatá · City guide
Bafatá lies east of the capital, and a visit to the surrounding area needs more detail than an intercity destination name. Save the host's approach instructions and the agreed return arrangement before travelling. Rural reception and the condition of onward roads can differ from what you encounter in Bissau.
Bafatá eSIM — set up before you flyBubaque · City guide
Bubaque is part of the Bijagós Archipelago, so a mainland arrival does not complete the journey. Establish how and where you will arrive, who receives you and how the return is confirmed. Ask about the specific island service area and keep essential details offline during the crossing and local transfer.
Bubaque eSIM — set up before you flyWhy Horizon
Data use during a Bissau work stay can include documents and shared laptop access. An arranged island stay may offer fewer opportunities to connect, while still needing validity through the return journey. Select the bundle against those tasks and dates. This is a data-only plan; rural terrain, island location, the device and network conditions affect service. Guinea and Guinea-Bissau are different countries, and neighbouring Guinea or Senegal is not included in a Guinea-Bissau country allowance.
Plan for
Guinea-Bissau
Compare the listed data allowances and validity periods for your destination.
Install over reliable Wi-Fi before departure and follow the plan's activation instructions.
Review the current price, data, validity and coverage before checkout. Horizon fixed-data plans have no throttling.
When the selected plan supports reuse or top-ups, My eSIMs shows the eligible options for the installed profile.
We'll alert you as you approach your limit. If the plan supports a top-up, My eSIMs shows the eligible options.
Choose country, regional or global coverage and check every destination in the plan details.
Guinea-Bissau has its capital at Bissau; Guinea has its capital at Conakry. Check the full country name on the offer and itinerary, as a plan for one does not supply the other's coverage.
Keep the receiving contact's instructions, the Bissau address and the onward arrangement outside your inbox as well as in it. If the trip continues to the Bijagós, identify that transport's meeting point separately from the airport pickup.
No. Confirm the supported island service area for the plan before purchase. Reception may differ between the mainland, an island town and a more remote shoreline, and no connection is established by the name of the country alone.
It needs preparation for periods without it. Save the booking or organiser's instructions, the receiving arrangement and the return details before boarding. Sailing operation and conditions must be confirmed with the organiser; the eSIM is not a boat communications service.
Hotspot sharing is free on every Horizon plan. Sharing needs a compatible phone and suitable settings; the work device consumes the same allowance as the handset. Horizon fixed-data plans have no throttling. Keep required documents offline if the connection is interrupted.
A Guinea-Bissau country plan does not include Senegal. Check an offer listing Senegal for that part of the trip, and verify current official border and travel advice separately. Keep onward directions and the receiving contact available before approaching the crossing.
No. Horizon fixed-data plans have no throttling. There is no daily limit that slows you down, so you can use your whole plan in one day if you need to. Your speed depends on the local network, your signal and how busy the network is. When your data allowance is used up, the plan stops rather than slowing down.
Yes. We always refund the full amount you paid when you request it, whether your eSIM is unused, partly used or fully used. There is no time limit for requesting a refund.
