ST4SIM: SIM & eSIM cellular connectivity portfolio
ST4SIM, connecting everything everywhere at any time
Cellular connectivity is a key enabler of connected devices. It uses mobile network operators' infrastructure (MNO or MVNO), increasing network coverage and maintaining seamless connectivity.
Leading to a greater diversity of smart objects, it paves the way to new market opportunities. To answer market needs, ST offers a tailored, diversified connectivity portfolio with ST4SIM solutions, a wide range of SIMs and embedded SIMs (eSIM) compatible with the IoT, industrial-and automotive-grade applications.
Our solutions allow several devices to be connected anywhere at any time, while ensuring asset security. The connectivity solutions provided by our partners complement the ST4SIM portfolio and enable worldwide coverage and product interoperability.

NEW: ST4SIM-201 for 5G M2M applications
ST4SIM-201 is the first product in the industry to receive the GSMA eUICC Security Assurance (eSA) certification. The latest generation of the ST4SIM product family, ST4SIM-201 is an embedded SIM dedicated to M2M communication, which can connect to 5G standalone networks.
ST4SIM, a complete portfolio of ready-to-use SIMs & eSIMs
eSIM technology brings new opportunities in the secure connected world. Directly soldered inside the device, the embedded SIM allows end users to change Mobile Network Operator (MNO) without changing their eSIM, offering more flexibility to manage device connectivity.
From removable SIMs to GSMA-certified eSIMs, the ST4SIM portfolio includes solutions based on basic configurations (ST4SIM-100), as well as cryptographic (ST4SIM-110), GSMA SGP.02 (ST4SIM-200) and GSMA eSA (ST4SIM-201) configurations.
