Please my fellow webmasters I am currently creating a game app and I want users to pay at some point in the game but I have noticed that Nigerians don't like using their debit cards online

This is why I have decided to charge their mobile lines directly just like 2go used to charge us but the issue is that I don't know how to go about it

Please I need help and contact with all these networks on how to program the app to charge the sim cards and also how to collect my money

Any help is appreciated
Thanks in anticipation
