E-SIM is a new technology that is being used by device manufacturers on both handsets, as well as wearables, to allow the devices to connect to cellular networks without having to insert a traditional SIM card.
The e-SIM is a chip that is added to the existing electronic control unit [ECU] of the device, which contains an embedded Identification [eID], similar to existing SIM card integrated circuit card ID [ICCIDs] that identifies each unique e-SIM and allows a cellular network to link it to a specific profile of a customer.
Vodacom One Number is a service that offers Vodacom subscribers the capability to connect their devices to a master number by linking different sim cards through embedded Sims, or e-SIM.
Customers can make use of the self-service functionality to deactivate the One Number Service or contact 082 135.
