Do you need your own data plan (not 0GB) to receive your extra rollovered data from previous month?
Let's say I will end my current billing cycle with a lot of unused extra mobile data. Let's say I change next billing-cycle's mobile plan to 0GB data. Could I use the unused data from this month next month? Or must I have at least a 1GB data plan?
I ask this question because I read that you need a data plan (i.e., not 0GB data plan) to receive data from others. So I wonder if this same must-have-your-own-data to receive your own data rollovers.
