About OneSIM

OneSIM sells travel eSIMs online. Travellers buy a data plan in minutes, install it on a compatible iPhone, Samsung or Pixel phone, and connect as soon as they land instead of hunting for airport Wi-Fi, while keeping their usual WhatsApp number.

Plans cover more than 190 destinations, including a global World eSIM, and validity starts only when the user connects abroad. Top-ups are supported. OneSIM is powered by One Telecom and serves customers from South Africa. It targets business and leisure travellers who want cheaper data than roaming.
