No answer from support, so I read again your instructions and found :
Need Help?
call customer service direct from your phone by dialing *MAX (*629)
So I dialed *629 ,- nobody answers , only answering machine and
I was immediately charged 0.29 Euro although on your
"How much does it cost" page
http://www.maxroam.com/how-much-does-it-cost.asp
there is no information about charge calling customer service.
I think it's not fair .
