Get powerful eUICC capabilities

Z-OSe is a highly advanced non-proprietary, vendor-neutral eUICC operating system specifically designed to enable remote provisioning of multiple network profiles on any device. The eUICC OS is available for both embedded and removable SIM formats offering secure profile management across new and existing legacy devices.

The functionality of Z-OSe’s eUICC operating system reduces the physical redundancy of the SIM and significantly lengthens its potential lifespan as profile additions, updates or deletions are securely provisioned and managed virtually by remote SIM provisioning (RSP).

Enjoy cost-efficient control with eSIM management

Workz offers highly-secure eSIM & eUICC remote provisioning, hosting & subscription services for both industrial M2M and consumer devices including:

  • Complete OTA solution with subscription management: data preparation, local testing and overall handling
  • Profile creation & testing, secure data management, provisioning and activation
  • Secure routing that supports HTTP for enhanced connectivity
