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.
I don't think it will be that hard if they intend to provide cheap data services like they intend to and they probably may use the iOS or android operating system to make this happen, i may be wrong though, its a lot of questions that needs to be answered, especially the hardware aspect, like do they intend to have like a collaboration with a major brand to develop this or what?
