MTN said:MTN Zone allows discounts of up to 100% for on-net calls and SMSs. It also offers up to 60% discount on calls and SMSs to other networks. These discounted rates apply to both the in-bundle and out of bundle usage,” MTN said
Whenever I see the words "up to" I stop reading, cause it is usually almost impossible to get the "up to" rate. The 100% discount only happens for 1 hour over the weekend and I'm not in the mood to set my alarm clock to check the discount every hour...
During the week MTN Zone works out more expensive than being on Anytime or One Rate on prepaid.
RBM is not offering "up to" 100 minutes (on RBM 100), they offer 100 minutes, period.
