Buy Minecraft with mobile plan?

Which website is this possible?

Pay Minecraft with the mobile number (get Tan in a text message)

Please do not suggest MMOGA, as the purchase is unfortunately not possible there.

Also do not suggest PaySafeCards, thanks!

Why is not the purchase possible at MMOGA? Otherwise I know no alternative.

I do not think that any provider a payment of 20+ euro let go.

Because ONLY there's that my O2 account is not activated. Have already written to MMOGA, who could only say that I should use an alternative payment option. Microsoft Store and another site where I could get a Netflix gift card went without problems.

Okay, that's weird.
