The data rate (Assuming a data bundle has been previously bought) is R0.15 / MB.
Which brings up three questions.
1.) What is the data rate, assuming no data bundle has been bought?
2.) How long after the data bundle has been bought does the data rate stay at R0.15 / MB
3.) Why would someone pay R310.00 for 2GB (R0.15 / MB) over R7.50 / 50MB (R0.15 / MB) if the OOB rate is the same, and identical to the In-Bundle (IB?) rate (Assuming pre-paid) ?
