Maybe we need data bundles that expire on 1 or 3 or 5 or 7 days. We can choose the expiry period. And we buy when we please.
that would be ideal although the sales systems are a bit more complex and what is really needed is for the MNOs to have a portal which allows for the setting of the quantity, the repeat factor and the amount to be allocated and allows for data limits to be implemented as well (to stop the OOB Shark) but more customer choice rather than less is what is needed
