[Skunkworks] OT: Individual Post paid voice plan on Airtel - Views needed

Hi folks, Anyone with experiences on the Kencell/Celtel/Zain/Airtel post paid scheme? I'm seeking to enroll on a personal post paid plan; primarily for voice use. I occasionally roam and data access is simply for light use browsing. I have received one nasty evaluation from a colleague on the same; citing weird charges & unaccounted for bill items. I need a couple more reviews to decide whether to enroll or not. PS: Limit the discussion to Kencell/Celtel/Zain/Airtel only. Tony.
