Hi - I am currently using another old phone (Iphone 7) on one of my lines for which I get Recurring device credit (RDC). The phone linked to this line and RDC (Samsung phone) is currently not used. I am planning to give it to my dad to use it on a new Tmobile account. My question - if I continue to make my monthly payments and keep my original line active, will I lose the credit (RDC), if the phone is activated on a new Tmobile account?
