I agree with Black Pudding; plus with IBQ you get 3 free international transfers a month, and with the Platinum credit card you earn 2% back on everything (was 5%.....was quite lucrative when putting school fees through the card!!).
With PAYG on QTel you can buy 'bolt-ons' for inetrnet or whatever. Or, if you have a Blackberry, you can get their Blackberry service pack for 15QR a week which is automatically deducted from your balance. I've been here 18 months and still on PAYG. I have 4 gig broadband here with QTel (not as cheap as UK) but no TV package. I tend to use a VPN and use BBC iPlayer, etc, for that. Depends how much TV you watch I suppose, we don't watch much.
