I am a Mozaic user, for 1 month.
Pros: It has landline, 512 kpbs internet and Tv bundle pack that separately will cost 200 for internet, 33 for landline (total 233) so 17 riyals only for Tv
Qtel gives the Wireless Modem and TV tuner equipment.
The remote is a programmable remote so you can set your Tv and DVD's remote in that - one remote for all 3.
Internet speed is good for 512 kpbs.
Cons: The internet access is only wireless, there is no wired (ethernet) connection, there is ports but Qtel disable it.
Qtel wont give the administrator password for the router, which has 2 Voip ports 3 free Ethernet ports for setting up.
Basic Asia (English, Basic Package) Tv Channel package is not a good bundle, more than half is useless channels, if you need to add more channels, still the combinations are not so good for 1 useful channel you will have to take another 4 useless channels.
I am not sure about the Arabic Channel bundles.

The soft Voip applications that I use works fine.
