Frequently Asked Questions

Questions Families Ask Most

What is an Engine Number?

A local number that helps your loved one call you at local rates rather than expensive long-distance rates.

How does an inmate add my number?

They add your Engine Number to their approved prison contact list, then calls can connect to you.

Do I need the 3CX app?

No. The app is optional. You can answer calls on your mobile, or use the app if preferred.

How do I get cheaper prison calls?

Prison calls can often be reduced by using a local Engine Number instead of standard mobile rates.

Can prisoners call mobile phones directly?

What happens if my loved one transfers prisons?

You can contact Engine Numbers for help updating the prison location. If a different local number is needed, we can guide you through the change.

How long does prison approval take?

Can I keep my number?

Yes, you can usually keep your Engine Number while your service remains active. If you need to restore a cancelled number, choose the restore option during signup.

Can multiple inmates call one number?

In many cases, more than one approved caller can use the same Engine Number, provided each prison approves the number on their contact list.

What if I stop needing the service?

You can cancel when you no longer need the service. There are no lock-in contracts.

How much can I save on prison calls?

Long-term plans can work out from $0.92 per day, depending on the plan you choose.
