Hi,
I used exensively verivox.de (that goes to Aufladen.de) to top-up by credit card my T-mobile sim, but now it seems they have some problems an accepting non-german credit cards (or customers): as a matter of facts, I correctly registered on their site, but all the attemps to pay by cc were unsuccesful (my wife has the same problem).
Moreover, it seems to me that their customer care isn't very bright, answering with trivial considerations.

Does anybody know other sites for on-line topping-up for german T-mobile sims?

Thanks a lot, and ciao
