Hello Tnx for your last advices. I configured my modem the way you told me, so I could detect my modem and dial it. My modem works well and I've got no problem (it dials the Phone no), But when it recognizes the provider I dialed, it gives 'No Carrier Error'. I use ppp-phone program. Also I unchecked the 'check Carrier', But it didn't work. What can I do? Tnx again
