Ubigi does not provide eSIM plans for South Africa that include a phone number or SMS capability. The provider offers only data‑only eSIMs for this destination, so travelers cannot receive ordinary text messages or carry out standard voice calls through a carrier number.
You can still use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for calls and messaging, but availability of these services can vary. Travelers should confirm that the apps they rely on are accessible in South Africa before purchasing an Ubigi eSIM.
