Wow, my bill never got even close to that.
Anyway, GPRS working now so I suppose it was a Q-Tel problem. I'm not sure I like having 3 different accounts though; freedom, mms and gprs.
Watch out on the data charges...I never asked what it actually costs...my last bill had GPRS charges at QR300 !!!!
Had a similar problem, found out that on the HALA prepaid all you can use your GPRS for is browse and download from their WAP portal and send MMS's... you cant do anything else.
If you are on a postpaid system then it should be working... just make sure your access points on your handset are defined correctly.
If you still having problems, let me know your handset model and ill let you know what else you can try.
