You obviously don't have much experience with the MTN network. This year I have only on one occasion not been able to use MTN GPRS. I think last year it happened about twice. I use MTN GPRS everyday for many hours a day. I don't call that "very unreliable GPRS".
On Vodacom on the other hand GPRS downtime is a daily thing. The users are already so used to it they don't even bother complaining about it anymore.
When i phoned 1555 on the MANY occasions i did... each time they said that a CERTAIN demographic of people are experiencing these intermittend issues. So maybe you know someone high up... or you suck up to the big boss.... because i'm online for at LEAST 18 hours a day, 7 days a week. And there are DEFINITELY serious issues from time to time.
All i know is that
www.yahoo.com should NOT take THIS long...

again this is NOT all day long... but that's been my point the WHOLE time. There are intermittend issues and its VERY annoying.
I have a colleague who's on Vodacom 3G who also travels all over SA and who is ALSO online for similar hours as i am. He doesn't have HALF the issues i have!
I'm seriously considering moving to Vodacom when this contract finishes
