have anyone used this service?

I could be interesting to learn more about this sim!

me too, but it seems nobody have used them!

yes, this is the risk... :-P

I've got one. They have nice and fast support via telephone and email. The service uses callback system. Minimum topup is of around 12EUR (100UAH). Payment options oriented maily on Ukrainian and Russian customers and as a foreign payer I was able to topup my account only using iPay.ua service (which seems to be VISA/MC verified) that accepted my credit card. Calling the card from betamax didn't work for me, but from another cheap voip service it did work. They have also SIP service which I did not try yet. According to their website they support also Multi-IMSI option where an additional Ukrainian number can be ordered.

where did you bought the simcard from?

I contacted them via email and their representative called me back.

which other voip service worked on calling these numbers? rebtel?
at what rate?

Rebtel charges 24 eurocents per min for these numbers. I do now know if it connects
