Now I am using UM+ with callback and no problem for the DTMF tones. I have not tried Yackie with DTMF tones and Callback, but it is on my list to do.
The potential problem with dtmf tone probably comes from compression that some operators are using. It seemed to me that manx was using to much compression making it the dtmf tones would not come thru. I tested the callback and dtmf allways using betamax and Um+ came thru and Manx did not. As this is not a betamax problems it must be the carrier that causes the problem.
Callbackworld has some great ratex on iceland mobile, seems very low and competitive.

Enlinea is a tad lower and worked extremely well for a friend to whom I loaned my O9 sim this past July in Italy, Greece and Croatia.
