Cancelling line with installment plan remaining
My daughter's new iPhone 13 Pro was stolen. We got the new phone by trading in her old iPhone X and got either $700 or $800 for the tradein, can't remember exact amount. The iPhone 13 Pro is about a month old. If I cancel the line I understand I owe the remainder of the installment plan. If the phone was purchased through tradein, can I just pay the difference of the tradein vs cost of phone? AT&T credits you on your bill each month but would rather not pay for extra line that's not needed and pay the installment plan (minus tradein credit) each month for remaining three years. Thanks you!
