I have a used prepaid sim card from a few months ago, can i reuse it for a new prepaid plan without visiting a T mobile store?

yes, you can re-use in 90 days! prepaid or postpaid!

This is very false information…

I always re-activate the used T-Mobile SIM.

Generally, if the SIM deactivated in 90 days, you can re-use the SIM again!

not to mention if the number has not been used in a certain amount of time the number itself will go into a pool to be recycled again to someone else. i think its a 60 or 90 day window.
