As a friend I can give you good advise. I have very bad experience with Q-tel connectivity in Raslaffan area.

The Q-tel 3G internet service is very slow and connectivity issue.

You will pay the more but you will not get anything .... if you want to use Q tel Dongle connection in Doha then its Ok but for Raslaffan is not successful.

I have outstanding experience with Vodafone and you can get Vodafone Dongle connection and use the connection in Raslaffan anytime.
The Vodafone company will provide you super faster internet with excellent connectivity.

VODAFONE HAVE EXCELLENT INTERNET CONNECTIVITY IN RASLAFFAN - CHECK FIRST AND THEN APPLY FOR PERMANENT CONNECTION.
