When you add money to an inmate's phone account online, it typically posts almost immediately. Online deposits through platforms like Securus are processed in real time in most cases, which means your family member can often start making calls within minutes of the deposit being confirmed.
For SCI Smithfield in Pennsylvania, Securus Technologies handles the phone service. You can set up an account and make deposits at securustech.net. When you add funds, you will need the facility name and your inmate's ID number to direct the deposit to the correct account.
