Hi Gang!
I wonder if anyone of you has ever used "Comfort Callback"

application software? How does it work? Is this only compatible with that SIM, some other SIM, is it virtually possible to have any software to actually hide callback? I found the software on the website and do hope that nobody minds if I post here a link --->
ComfortCallback Software - Help Desk I don't have a TavelSIM so can't test myself. Many thanks. Stan.
