AdvancePay® Prepaid Telephone Accounts
To accept calls from an inmate at this facility, we recommend you create an AdvancePay® prepaid telephone account. Prepaid calling works by placing money on your phone number so that when your inmate calls you the funds are deducted from the balance on your prepaid account.
