I have "T-Mobile To Go" service. I was wondering what happens when my balance becomes zero. Will my phone instantly become de-activated or is there a grace period before my phone number is given away?
You will have 90 days to refill. After that period your account will be canceled and you will lose your phone number. If you want to restart service, you will need to activate new service. Look here for more details - http://www.t-mobile.com/shop/plans/d...plancategory=4
