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), thereby increasing network coverage and maintaining seamless connectivity.
Leading to a greater diversity of smart objects, it paves the way to new market opportunities. In order to answer the needs of the markets, 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.
ST4SIM, a complete portfolio of ready-to-use SIMs & eSIMs
eSIM technology brings about 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, thereby offering more flexibility to manage device connectivity.
From removable SIMs to GSMA-certified eSIMs, ST4SIM portfolio includes solutions based on basic configurations (ST4SIM-100), as well as cryptographic (ST4SIM-110) and GSMA SGP.02 (ST4SIM-200) configurations.
