Yeah but what about when you get a new phone and sign a new contract. I read that as, if your contract ends but you keep using your phone, no change.
Sounds like just as long as you don't change your plan, you can get a new phone and extend/renew your contract and remain grandfathered. Only if you change your plan (ie going from 900 minutes to 450 or something) do you fall out of the grandfather clause.
The way I read it is as long as you don't change to a different type of phone (say downgrade to a non-smart phone and then try to go back to smartphone) then you should be all set. I wonder if even changing the minutes plan would matter? The last line of my quote would seem to indicate not:
"Device type" I take to mean smartphone vs. non-smartphone. I don't plan on changing my plan anyway, so it doesn't matter to me right now. I would like to get a new smartphone the next time I upgrade though...as long as your line remains active within the same device type
