345 of these 650 plans were checked against the seller's own shop on 16 October 2026. The rest come from the seller's own feed or plan pages and are not yet independently checked.
The Watchdog Pick is chosen automatically: the lowest real price per GB of the 650 plans in this view. Bulk data pools above 50 GB cannot win it, because their per GB rate only exists if you use data no traveller uses. Providers cannot pay for it, and a commission never changes the ranking. Prices are shown in USD and can change at checkout.
Price per GB counts only data you can use inside the validity, at most 3 GB a day, so a big pool on a short validity cannot buy the top spot. Every provider's best two plans come first, then the rest. A plan marked Unverified price undercuts every other provider here by more than half and waits at the end until we have checked it on the seller's site. How we rank
Unlimited rows show the daily amount at full speed. Some rows also show the speed after that amount. A row with no speed does not mean the plan stays fast, so check the plan on the seller's site.
Some links here earn us a commission. It never changes the order. How we make money The row marked Sponsored is a paid placement shown above the ranking, not part of it. Advertise here.

Cheapest eSIM for Guinea-Bissau: the numbers
As of 16 October 2026, 06:08 GMT, the cheapest eSIM for Guinea-Bissau is Tourist eSIM with 20 GB for 31 Days at $27.76. That is $1.39 per GB, the best rate of the 650 plans we compare from 50 providers. 312 support top ups. That timestamp is the exact moment of our latest price check, and the table above always shows the live order.
Which is the best eSIM for Guinea-Bissau?
There is no single best eSIM for Guinea-Bissau, because the right plan depends on how long you stay and how much data you use. What we can do is rank the 650 plans on the numbers, as they stand on 16 October 2026:
- Best value overall Tourist eSIM, 20 GB for 31 Days at $27.76. That is $1.39 per GB, the lowest real rate of every Guinea-Bissau plan we track.
- Best for a short trip eSIMzio, 1 GB for 5 Days at $4.00. The cheapest ticket that still gives you at least 1 GB for a week or less.
- Highest daily cap on an unlimited plan SimSmash, 1 Day at $34.49, full speed up to 10 GB a day. Set that daily cap against the fixed plan above before you pay for the word unlimited.
None of these picks is chosen by a person. Each one is the first row of a sort on live prices, so it changes whenever a provider moves a price, and Tourist eSIM did not pay to be named here.
Which mobile networks does Guinea-Bissau have?
Connectivity is functional but patchy. Bissau's main streets and the airport have 3G and 4G, while the Bijagos islands and inland villages often drop to 2G or no signal at all.
- Orange Bissau: The market leader since 2013 with roughly 52 percent market share and the best overall coverage.
- Telecel Guinea-Bissau: Telecel Group completed its purchase of MTN Guinea-Bissau in 2024, taking over the country's other main network.
The eSIM plans we compare on this page connect to:
The list above is Guinea-Bissau's operator market. The badges are the networks our tracked plans actually roam onto, which can be a subset of it, and the same network is sometimes sold to roaming partners under a different brand name. So a guide praising an operator you do not see badged here is describing a local SIM, not the travel eSIMs compared above.
Is 5G available in Guinea-Bissau?
There is no 5G in Guinea-Bissau. Some operators offer 4G in urban areas, and coverage varies from town to town.
How much data do you need in Guinea-Bissau?
Light use is about 500 MB a day. That covers maps, messages, and some browsing. Normal use with photos, social apps, and short videos runs 1 to 1.5 GB a day. Streaming and hotspot use can eat 2 to 3 GB a day. Here is what each size costs in Guinea-Bissau right now:
Are unlimited eSIMs for Guinea-Bissau really unlimited?
Not always. 221 of the 650 plans above are sold as unlimited, and most of them carry a daily fair use cap. For Guinea-Bissau the caps we can see published are 0.5 to 10 GB a day: past that the speed drops, often to 1 Mbps or less, until the clock resets. That is fine for messages and maps, slow for video. At $1.39 per GB from Tourist eSIM, a fixed plan often works out cheaper than unlimited unless you genuinely burn several GB a day. That is why we rank by price per GB and not by the word on the label.
Here is what each seller on this page actually allows per day before it slows you down. No seller publishes this next to its rivals, which is exactly why it is worth showing.
Every seller that publishes a daily allowance is listed on our daily data caps page, with the cheapest plan at each one. The gap between the top and bottom of that table is the whole point. Two plans both sold as unlimited can differ several times over in what you actually get at full speed, and the cheaper one is not always the smaller allowance.
eSIM or a local SIM card 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 for a tourist SIM card. Data for Guinea-Bissau starts at $2.00 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
Pick the plan, not the brandThe cheapest rate in Guinea-Bissau today is $1.39 per GB from Tourist eSIM, against a median of $7.02. The QR code arrives by email within minutes of paying.
Install before you flyScan the QR code on wifi at home. Installation needs a connection, and the one thing you will not have when you land in Guinea-Bissau is a working connection.
Turn it on when you landEnable the eSIM and turn on data roaming for it, then give it a minute to attach to MTN, MTN Areeba, Orange, Orange Bissau. Expect 4G.
Know what happens when it runs out312 of the 650 plans here can be topped up, so running out is not the end of the trip. If you would rather over buy than top up, the cheapest plan with at least 5 GB is Saily at $15.49.
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.

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.
Does a Guinea-Bissau eSIM work on iPhone and Android?
Yes, on any carrier unlocked phone with eSIM support: iPhone XS or newer, Google Pixel 3 or newer, Samsung Galaxy S20 or newer and most recent flagships. The plans are identical on both; only the install steps differ, and both take about a minute on wifi.
