the local telecom company Qtel offers both cable tv and internet services.

Qtel's cable tv is crap..so don't get that. If you buy a satellite dish you'd find about a handful of free-to-air english channels..but not particularly impressive. Alternatively you may subscribe to either "orbit", "first net", or "showtime" (i prefer the latter). As a general rule that should cost you anything from 120 QR - 300 QR monthly depending on the package you opt for.

About internet..Qtel's internet service isn't half bad..but it is very heavily censored. They offer both dial-up and DSL connections..but most people get DSL. The packages are:

512 KB = 200 QR per month
1 MB = 300 QR per month
2 MB = 400 QR per month

the modem and installation are usually provided for free, but if no promotion is going on at the time they should cost you an extra 350 QR (i think).

hope that helps!
