Botswana has two main operators: Mascom (majority owned by MTN) and Orange Botswana (part of Orange Africa). Both provide 4G coverage in Gaborone, Francistown, Maun, Kasane, and towns along the main road network. A third operator, beMobile, is smaller and focuses on areas underserved by the two main carriers.
Gaborone has the strongest coverage with solid 4G across the city center, the Main Mall, and residential areas. Maun town has 4G coverage, but signal drops quickly once you enter the Okavango Delta by boat or mokoro. Kasane, the gateway to Chobe National Park, has 3G to 4G in town. Inside Chobe, signal disappears in most park areas.
The Okavango Delta is covered by water channels and flood plains. No mobile network provides reliable coverage across the delta. Lodges and camps use satellite internet. Download offline maps of the delta channels, Moremi Game Reserve, and Chobe before any bush departure. The Central Kalahari Game Reserve, one of the world's largest wildlife reserves, has no mobile coverage. Only Ghanzi, the nearest town on the reserve's edge, has 3G coverage.
