To accept a collect call from an inmate, make sure the cell phone carrier allows collect phone calls from inmates and make sure that there is no unpaid bill associated with the line for prior inmate calls. In some cases, the inmate must list telephone numbers on a pre-approval sheet.
If the cell phone carrier does not accept inmate phone calls, most inmate calling companies allow call recipients to purchase prepaid phone cards or contribute to an account for an inmate to use to make calls. In addition, most prisons require inmates to list a limited numbers of phone calls that prison staff reviews and grants advance permission for the inmate to call.
Collect calls from an inmate typically appear on the recipient's regular phone bill and some of the companies that facilitate prison phone calls also allow call recipients to view bills online. Call recipients have the option to establish cost limits.
