Guinea Bissau has two operating mobile network providers in the country.
Orange Bissau - (Run by Senegal's SONATEL)
MTN (Run by South African mobile group)
Guinea Bissau used to have a government-owned network provider called Companhia de Telecomunicacoes da Guine-Bissau also known a Guinea Telecom however the provider was discontinued due to lack of funds.
Orange Bissau has the largest market share which is 52%.
It was the first company to launch 4G internet in the region back in 2015.
It has also been the market leader for the last years from 2013.
The network coverage of Orange is the largest in the country hence the reason why it attracts a large market.
The SIM cards can be bought right outside the airport and the vendors will ask you to buy the SIM cards.
The SIM cards can also be bought at the orange stores within the country.
The purchase of the SIM card does not allow one to have an identification card.
The SIM cards cost 1000F and do not come with any preloaded talk time or data bundle, for this, you have to recharge your SIM.
Top up cards are sold ranging from 500F, 1000F, 10000F and 25000F.
To top-up, you will have to dial *123*[voucher code]#.
to check balance, dial *123#
To access the internet, one has to buy a package called pass internet and the package can be as cheap as 200F where you get 40MB or can be as expensive as 50000F where you get up to 75GB
This is the second-largest network provider in the country and although it advertises 4G internet, this is hardly found.
At times the best that can be found is HSPA.
The sim cards are bought for 500f without any preloaded talk time or data bundle and voucher cards can be bought in any local shops or in supermarkets.
