I must say I am not really sure how this will work, yet. Are they planning to build their own mobile operating system? It will be hard to compete against Android, iOS and the Huawei OS.
from the information i have gathered so far i don't think they are planning to build an os i believe they are trying to create a network layer that will operate without the need for sim hence the sim-less nature what i don't get is how will it happen. i have not gone through their whitepaper for technical information
