Carrier On free 200mb, if I upgrade to 5GB/month from TMobile, what happens on downgrade?

[Bottomtotop]

Will I be able to keep my free 200mb per month plan from T-Mobile when I downgrade again? Anyone know?

I need the T-Mobile 5GB/month ($40/month, no credit check) for the next 2.5 months.

Yes, the 200MB plan is for the life of the device so it will renew monthly.

Also, you'll conitnue to have the 200MB even when you have the 5GB pass added on, so it'll actually be 5.2GB.

In my case with a postpaid plan, the first 200MB of usage aren't metered. Then all usage after that gets metered and counted against the data plan I paid for.
