I have my air on a t-mobile post paid plan and also activated the 200mb free data every month. The issue is the billing cycles on the two plans don't line up. When using their account app, I can see the respective remaining allowances, but the allocation seems inconsistent. My only concern with this is not being able to maximize the plan soonest to expire instead of the later allowance being hit first. Anyone have any info? Hoping someone has some info here instead of having the ring support considering how bad the whole free data rollout was in the first place.
