eSIM Guinea-Bissau: Reliable 4G/LTE for Bissau & the Bijagós Islands

Welcome to Guinea-Bissau, a hidden gem of West Africa, known for its vibrant culture, cashew exports, and the pristine Bijagós Islands. Whether you are in Bissau for business or NGO work, or exploring the untouched natural beauty of the archipelago, a reliable internet connection is essential.

Stay connected in this unique destination with Cellesim's Guinea-Bissau eSIM plans, starting at just $17.80. Choose from 6 limited and 10 unlimited plans.

CRITICAL: Avoid Astronomical "Rest of World" Roaming Fees

IMPORTANT WARNING: Guinea-Bissau is NOT included in any standard international roaming bundle (North America, Europe, etc.). For your home carrier, this is one of the most expensive "Rest of World" or "Pay-As-You-Go" zones.

Using your home SIM here can lead to astronomical charges, often per-megabyte, for basic data use. A Guinea-Bissau eSIM is the only smart, predictable, and cost-effective way to get internet. Get connected the moment you land at Osvaldo Vieira International Airport (OXB) in Bissau.

Why a Cellesim eSIM is Essential for Your Trip to Guinea-Bissau

• Instant (OXB) Airport Connection: Get online the moment you land at (OXB) Airport. This is critical for coordinating transport or contacting your local team.
• Prevent Extreme Bill Shock: Our 1 GB plan is vastly cheaper than what you would pay for just a few megabytes of data roaming. You know the cost upfront.
• Keep Your Home Number: Your eSIM handles the data, so your primary SIM (and your WhatsApp number) remains active for essential calls and texts.
• Reliable 4G Connection: We partner with top-tier local operators (like Orange Bissau or MTN) to provide the best available 4G/LTE connection in Bissau and key regional towns.
