The ETravelSim South Africa eSIM runs on CellC, one of the country's four major mobile networks alongside Vodacom, MTN, and Telkom. CellC has solid urban and suburban coverage across the metros where most travellers spend their time. For trips focused on Cape Town, Johannesburg, the Garden Route, and main Kruger camps, it covers the route. For deep-bush safari camps in private reserves outside Kruger, Vodacom-based plans typically have wider rural reach.
