Virtual SIM (vSIM)

Virtual SIM

A virtual SIM that uses Caburn’s platforms and API for communications where no physical SIM is required.

Each virtual SIM ICCID is allocated a unique and valid telephone number which can receive SMS messages via our portals.

Every message can be easily viewed and managed via our Management Platform and Portal, meaning that the authentication and ongoing maintenance of B2B or consumer ready IoT devices that require a telephone number has never been easier.

Authentication, aggregation, and delivery

Caburn Telecom provides the vSIM facility to enable authentication, aggregation, and delivery of messages to unique virtual telephone numbers.

These can be attributed to individual devices when deploying consumer devices in large volumes, where each requires to be assigned a unique user ID/mobile telephone number.

This is typically for account authentication and centralised management purposes.

For instance, many devices (i.e., video conferencing facilities, smart home equipment and smart voice-prompted equipment), use Wi-Fi for their device connectivity but still require a unique user/secure telephone number to enable their services and allow ongoing centralised management of them.
