You never bought credits, and you never will. So your argument about "bring transfers back because not all countries can buy credits via SmS" is flawed. About offering to everyone a fair game, with same winning chances, I'm proposing you a quiz.
Do you believe, that a player, a good player even, from a country that has Premium Sms option but who hasn't a friend in TC Crew, to supply him with credits when he plays, has the same winning chances as a Brazilian or an Argentinian who has access to almost limitless amounts of it?
