I'd like to know. What is the advantage of these SIM cards in terms of using only for communication? And what is the monthly service fee?
A major innovation by FIX Network is to store these keys on the subscribers SIM cards using cryptographic-enabled applets on those SIM cards. This will enable secure access to our digital lives wherever we go, with cryptographic operations being executed by the SIM card itself, never exposing the private keys to the mobile device or a public network. In addition, to increase security, private keys may be segmented and distributed over multiple SIM-enabled devices, with each device storing only a portion of the shared key. This segmented/distributed architecture also facilitates the recovery of security keys if a device is misplaced or damaged.
Aim of the project is to enable the mobile operators to integrate this into their SIM cards but since this won't be happen until there a traction and demand before, that's why team is going with their own SIM cards in the starting.
PS- FIX SIM coverage is already in more than 170 countries at the moment
there is only one time fee and no monthly fee for lifetime.
