Why do you still need to hold ICO if you have working platform already? You can use the funds generated from your 10000+ sim cards that you sold and more than possibly you have private investors on this project. ICO is not a thing anymore so I don't know if you can achieve your financial targets on this crowdsourcing strategy.
I also asked this question and got no answer. But for me it would be very important to understand. I would like to get comments from the team about this.
