Idea in testingOur own eSIM · not yet available

What if it was just $5.00 a GB, everywhere?

We are considering a BetterSIM eSIM at one flat rate worldwide. No tiers, no bundles, no per-country price shopping, no volume discounts you never reach. The same $5.00 in Guinea-Bissau as in Fiji or Kenya.

Your 4 GB would cost$20.00($5.00/GB, credit never expires)

Straight answer: this would not be the cheapest option. The plans listed on this page are often less per GB, especially in Europe and Asia. It would be the simplest. Savings against Google Fi depend on usage, Bill Protection and speed needs.

How this would work

City-by-city connectivity in Guinea-Bissau

Carrier coverage is the same nationwide story; the airport, the subway, and the free WiFi situation change city by city. Here is what travelers asking specifically about these cities actually need to know.

Bissau

Arriving
Osvaldo Vieira International (OXB) is close to the capital; transfers are by taxi. The airport has basic 3G from Orange and MTN. Bissau is the capital and effectively the only place with functional data in one of Africa's least-connected countries. Download everything offline before arriving.
On the subway and rail
Bissau moves by shared taxis (toca-tocas) and minibuses; there is no metro. Coverage holds across the central areas, though speeds are basic. The Bijagós Archipelago, the country's main draw, has minimal or no coverage on the islands.
Free public WiFi
Hotels, where available, provide the most reliable WiFi. OXB airport has basic WiFi. Connectivity is concentrated in central Bissau; plan for a largely disconnected trip.
Coverage in the city
Orange and MTN run basic 3G across central Bissau and the Bissau Velho old quarter. Coverage is minimal elsewhere. The Bijagós Islands have very basic service on the main islands (Bubaque) and none on the smaller ones; this is one of the least-connected destinations on the continent.
If you prefer a local SIM
Orange and MTN sell SIMs in Bissau. Almost no international eSIM providers cover Guinea-Bissau, so a local SIM or hotel WiFi is the only realistic option; download maps and guides offline before any island trip.

Local Network Insights

Curated tips to help you stay connected in Guinea-Bissau.

Grab an eSIM before you arrive in Guinea-Bissau to skip local SIM queues. Most urban areas offer 4G or better, while rural regions can slow down, so keep offline maps handy. Activating the eSIM in advance ensures you are connected the moment you clear customs.

Connectivity Overview

What to expect for mobile connectivity in Guinea-Bissau.

Guinea-Bissau has very limited mobile infrastructure. Orange and MTN provide basic 3G service in Bissau, with minimal coverage extending to a few secondary towns. The Bijagos Archipelago, the country's main tourist draw, has very basic connectivity on the main islands and none on the smaller ones.

This small West African country is one of the least connected destinations on the continent. Travelers should plan for very limited digital connectivity throughout their visit. Download all maps, guides, and essential information before arriving. Hotel Wi-Fi in Bissau, where available, may be your most reliable internet access.

Practical Data Tips

  • Almost no eSIM providers cover Guinea-Bissau
  • Only Bissau has functional cellular data
  • The Bijagos Islands have very basic or no cellular coverage
  • Download everything offline before arriving
  • Hotel Wi-Fi in Bissau is your best connectivity option

Before you fly: a 6-step checklist

The mistakes that cost travelers in Guinea-Bissau are almost always procedural, not which-eSIM-did-you-buy. Here is the order of operations that works.
  1. 1

    Buy and install at home on WiFi.

    Installation is not the same as activation. You can install the Guinea-Bissau eSIM days ahead and only switch it on after you land, which avoids burning days of validity in transit.

  2. 2

    Screenshot your current APN before you swap.

    If you ever need to switch back to your home line quickly, that screenshot saves a support call from a foreign airport.

  3. 3

    Choose your travel data line.

    On iPhone, select your travel eSIM in Settings > Cellular > Cellular Data. Follow your provider's roaming and activation instructions. Choosing a data line does not by itself prevent charges on your home line.

  4. 4

    Decide whether to keep your home line on.

    You do not need to disable iMessage simply because you use a travel eSIM. Apple’s travel eSIM guidance says iMessage and FaceTime can continue using your home line while traveling. If you keep both lines active for home-number calls or SMS, your carrier may charge roaming fees. Check your carrier’s terms before leaving your home line on.

  5. 5

    Download offline maps for Guinea-Bissau.

    Google Maps and Apple Maps both support offline regions. Pull them down on home WiFi so a flaky activation never leaves you without a route from the airport. Our offline maps guide walks through it step by step.

  6. 6

    Activate at the airport, not before.

    Once the validity timer starts it does not pause. A 15-day plan you turn on the morning of departure burns a full day of validity before you even land.

How we built this page

Country plan prices come from stored supplier snapshots. The catalog contains different data amounts and validity periods. Provider ordering uses the unweighted average $/GB of fixed plans, or the PAYG rate; unlimited plans are excluded from that average. Check a plan’s data, validity and total price against your trip before buying.
