The telephone contract now allows for prisoner calls to cell phones using debit or prepaid service. There are three way to make  a collect call from a MDOC facility:

1. A person's local business phone company has a billing agreement with EMBARQ.  In this scenario, the person would be charged on his or her monthly phone bill.
   
   
2. A prepaid account can be set up with Correctional Billings Services. (CBS).  CBS can be contacted at 1-800-844-6591.  As long as the person has money on the prepaid account, collect calls would be routed to their telephone instead of being blocked.
   
   
3. A debit telephone system where a person can send money to a inmate.  The inmate can then have that money applied to his or her debit account.  The call operates as a collect call, but the prisoner's debit account is charged for the call, not the person receiving the call. The first deposit into the account must be at least $20 and increments of $5 thereafter (e.g. $25, $30, $35, etc).

There is a 15 minute maximum time limit on every call made by an inmate
