Do I sign up for Payment Reminder text messages separately for each policy or account bill?

No, Payment Reminder text alerts are delivered for all of your policies/account bills and not available for individual policy/account bill selection. When you enroll in Payment Reminder text alerts, you will receive a text message that represents delivery to all your policies/account bills. Text alerts will then be delivered for each policy/account bill each time your payment remains unpaid and enters the five day window prior to the due date.
