i'm currently enquiring if the monthly package has off peak rates also and the cost if you need to go beyond the packages, it might actually become better than telone.
I've been running Max365 as a backup connection for when telone goes down, and i have friends that work at UMax - i have to say they have the best customer service between Zol, Telone, Yoafrica and themselves and i agree they might not be the outright fastest but they are the most consistent and reliable (external fibre issues not withstanding of course)
