Z-OS operating system allows network operators to maximise their SIM.


Workz Group, the telecoms subscriber products manufacturer, security printer and serialized software specialists, today announced the launch of its most advanced SIM operating system Z-OS.  The OS is the smallest and most optimised SIM OS currently available on the market with it being approximately 40% smaller than other SIM OS.  This gives network operators greater opportunity to add Value-Added-Services and revenue-generating features to their subscriber SIM cards.


Z-OS was soft launched in May earlier this year and has subsequently been tried and tested in various markets.  The system was developed to enable a range of features with secure and reliable Over-The-Air management of applications.


The product complies with leading international SIM standards defined by ISO, ETSI, 3GPP, Global Platform, Oracle Java card, SIM Alliance and the GSMA as well as its proposed eSIM specification.  The Z-OS is designed to be compatible with both Java and Native products and is offering in several chip sizes from 32k to 256K and available from all leading chipset manufacturers: Samsung, Infineon, EM Micro, etc.  It is also interoperable with all network technologies: 2G, 3G, CDMA and LTE.


Z-OS is offering in conjunction with Workz latest SIM offering the 3-in-1 seamless half SIM which uses only 50% of the plastic of a traditional SIM card and works in any handset by allowing the user to select which SIM module size to push out.


We’re very proud to present the world’s most efficient SIM operating system.  The Z-OS is a significant technological advancement which allows us to provide network operators with more customised applications on the SIM card to engage subscribers.  The investment we have made in our Dubai SIM facility has enabled us to provide the highest standards of security, reliability, and performance in every aspect of our full SIM solution from development, manufacturing and product delivery.  Furthermore, with everything produced under one roof we are also able to provide extremely competitive turnaround times.Brad Taylor, CEO, Workz Group
