OR will he be charged just when he hang up the phone when the call back calls him?

Is there any tip that allow me to know that he is avalaible for me to call him with no cost for him? (i mean that his credit of 10 euros will be not charge)

Thank you for helping me

No, the function of most callback systems, including on his SIM card, means that the call initiator gets the callback to their own phone, and only when it's answered will the destination number start to ring.

At this point, some independent callback systems are charging the first leg, but others do not charge until the second leg is answered as well. Unless things have changed, the SIM card is in the latter group, so if he then hangs up, I don't think he will be charged, and you could call him.
