There are two very simple reasons to keep it simple in Mobile, MVNO, IoT and even MVNE, MVNA, MVNx: 1) Simple sells; 2) your competitors think it won\’t! (never underestimate how much your competitors will try and thwart what they see as a \”competitive\” service / tariff)… (or how they won\’t see a simple tariff overtaking the market until its too late).
