PM should allow us to have flexibility carrying over un-used data to next billing period. Please consider to have this option for at least 90 day plan users.
Since we are a prepaid company, there is a ton of complexity to carry over unused data from your plan to the next billing cycle. That being said, we won't changing this capability. It is important to note, however, that our Canadian Data Add-Ons all carry over until they are used up. Hope this little tidbit of information is useful
