T-Mobile announces tiny new "embedded SIM" for connected devices
Sure, SIM cards are small, but they're not tiny, and fitting the entire assembly into an embedded device requires a lot of space -- so T-Mobile's new embedded SIM system should make it possible to build even smaller connected devices like hospital monitors and smart energy meters that can report back to a server. The new SIMs are the size of a pinhead and made of silicon instead of plastic, which allows them to be coded at the factory and hard-mounted directly to a device, skipping the provisioning and installation steps that would come with regular SIMs. Devices with the new SIMs are expected to be out and sending data over T-Mo's network in as little as six months -- the first is an energy meter from Echelon that should hit soon.
