does cing grandfather plans now?

i ask this, 'cuz years ago when i had cing (then southwestern bell) after my contract ended they started charging me by the minute (all promotions gone, and no plan apparently).
this has me worried that when my attws account gets transfered to cing will i have watch for when my contract ends, since attws doesn't do anything to your account until you call in to change it, even after your contract is up.

also surprising swb had never called me up to try to get me to renew my contract either.
