Embedded SIM Design Means No More Swapping Cards

Posted by timothy on from the but-watch-for-the-new-skimmers dept.

judgecorp writes "A new remotely-programmable embedded SIM design from the GSMA operators' group means that devices can be operated on the Internet of things and won't have to be opened up to have their SIM card changed if they move to a different operator. The design could speed up embedded applications."

  1. Who, exactly, gets to send over the air updates? by Animats · · Score: 5, Informative

    To fix this issue, the GSMA has developed a non-removable SIM that can be embedded in a device for the duration of its life, and remotely assigned to a network. This information can be subsequently modified over-the-air, as many times as necessary.

    What this seems to do is take control away from the user, who could swap SIM cards, and give it to some carrier. This looks like something where you beg and plead with your old carrier to let you switch your device to a new carrier. There's a lot of elaborate key management in this system, and compromise of certain keys could break the whole system.

    Spec for the system architecture.

    It's marketing, like "the cloud". It's such a gross oversimplification that it's meaningless.
