This issue is due to your country policies, our mobile providers cannot offer a price for SMS more than what your mobile carriers specified as a maximum cost for an SMS. Paygol was allowing you to get 2000 points probably for the same maximum price (around 50 VEF) which is 5 EUR. This is not a price we would have ever setup for a 5 EUR mobile payment (its only due to a stupid provider system).
I'm sorry but i have looked over all the other possible mobile payment providers and they all seem to be limited for the 50 VEF price offer (which wouldn't get you much points). I recommend you to use Credit Card which exists in every country around the world.
