I was sold Mosiac by a tele-salesman as an add-on to my existing internet package.
I was told that it would cost at QAR 17 extra per month.
The Qtel bill is SO COMPLICATED that I have no idea what it is really costing me.
It worked for one day, and has never worked since. Still trying to report it !

Moral of the story :
Avoid telesales, even from a telecomm company.
Mosaic is a disaster. Avoid it.
