eSIM for Guinea-Bissau — Instant 4G/5G Data Plans

Guinea-Bissau's mobile network is served by operators including MTN Guinea-Bissau and Orange Guinea-Bissau. 4G LTE coverage is limited and primarily available in Bissau, with 3G extending to some secondary towns and main road corridors. The Bijagós Archipelago, which comprises around 88 islands off the coast, has very limited mobile coverage outside the main inhabited islands, and many of the archipelago's nature reserve areas have no signal. Rural interior regions near the Senegal and Guinea borders may also have limited connectivity. MobiSIM connects through supported local networks to deliver the best available data for your location across Guinea-Bissau's main urban areas.

Install your MobiSIM eSIM before landing at Osvaldo Vieira International Airport in Bissau so you have data ready in the capital. Download offline maps for Bissau and any Bijagós island destinations before travelling, as connectivity on the archipelago is very limited and ferry crossings take you quickly out of coverage range. Keep your home SIM active for calls while MobiSIM provides your data connection in covered areas. The Bijagós Archipelago is a UNESCO Biosphere Reserve and one of West Africa's most pristine natural destinations, but its remote location means treating all island visits as largely offline and preparing all lodge contacts, boat schedules, and emergency information before departing Bissau.
