So when I got the invite for the B-Live launch, it sounded like Safaricom was doing a full shift from quantity-based usage to time-based usage. Well, during the launch, it turned out that they were just launching a time-based data bundle and not a full shift as I had initially thought. Also, when you look at B-Live closely, you realize that it is not full time-based usage since they still have the fair use cap on different offers. If your specific need is much longer hours, then there is an option of buying 4.5 or 6 hours. B-Live data bundle is available via *544# or *555#.
