FS.38 is the only standard that delivers bank-grade security at zero incremental hardware cost for cellular IoT. gsma fs.38

The spec is mature, the applets are available, and the major MNOs have already rolled it out across their IoT eSIM portfolios. Elias took a sip and looked at the glowing screens

If the eSIM is the digital passport for a device to travel across different mobile networks, FS.38 is the standard that dictates how tamper-proof that passport must be. With them, we have a shield
