The prices for points are united for all countries, the mobile payment provider (Forumo) gives you an equivalent amount of points based on the maximum set-up cost per SMS in your country. Some countries have a high ratio into mobile SMS and can be up to 40-60 EUR per SMS, few other countries which like in your case has a restriction on the maximum cost of a mobile SMS. There's no thing from our side we can actually to fix this, but in such cases we always recommend relaying on the other available payment methods such as Credit Card and PayPal. I understand that you might have not crossed 18 yet, but you may use your parents credit card with their permission of course.
