Infineon’s OPTIGA Connect eSIM Solution For 5G Mobile Devices

  • Supports 3G to 5G
  • Robust, secure and reliable for telecommunication and embedded devices

Infineon Technologies has extended its embedded SIM (eSIM) portfolio with the introduction of the OPTIGA™ Connect eSIM solution. Built for mobile telecommunication devices, it fully supports all GSMA standards from 3G to 5G and securely authenticates the device to the subscribed carrier network.

With integrated hardware and software, the device is perfectly matched for smartphones, tablets and wearables like smartwatches or fitness trackers thanks to its small footprint. At the same time, manufacturers can now develop product designs efficiently by reducing their eSIM integration efforts and time to market.

Secure and Tested

Based on Infineon’s SLC37 security chip, the new OPTIGA Connect solution meets the GSMA’s security requirements and is tested according to Common Criteria CC EAL4+ high. The chip provides a robust and trustworthy security feature, which is necessary to protect sensitive keys and data against illegal use.


Furthermore, the solution fully complies with the latest 5G specifications from the GSMA (SIMAlliance Profile Interoperability 2.3 Spec) and the 3GPP. It supports the profiles of major mobile network providers with Remote SIM Provisioning capabilities and offers up to 1.2 MB of free user memory for network operator profiles, data and additional applications.

Package size of only 2.9 mm x 2.5 mm x 0.4 mm allows the development of new designs, especially for devices where adequate PCB space is required.


The OPTIGA Connect eSIM consumer solution will be available from March 2020 onwards. According to the global tech market advisory firm ABI Research, global shipments of eSIM enabled smartphones is expected to grow over 225 million in the same year.
