The Tourist SIM: What to Ask For
When you arrive, simply ask for a “cartão SIM pré-pago” (prepaid SIM card). Specify you are a tourist (“sou turista“) and want a plan with internet (“com internet“). The vendor will help you choose the best plan for your stay.
Digital eSIM Providers
If your phone is eSIM-compatible (e.g., iPhone 12+, Google Pixel 3+, Samsung S20+), you can skip the physical SIM entirely. Providers like Airalo, SimOptions, and Orange’s own Travel eSIM offer data plans for Guinea-Bissau that you can install before you travel. This is the most convenient option.

The vendor will handle activation, which is usually instant. You may need to restart your phone.

Conclusion
For most travelers, Orange offers the best combination of nationwide coverage and reliable data speeds. MTN is a strong contender, especially with its competitive social and short-term bundles. If you’re staying primarily in Bissau, Saar-Bissau can offer great value.
However, for sheer convenience and immediate connectivity upon landing, a travel eSIM is unbeatable. Assess your needs based on your itinerary, data consumption, and device compatibility to make the perfect choice for staying connected in Guinea-Bissau.
