Q: So, if using the inmate aid phone calling cost of $19.95 for the 300 minutes monthly. Is it cheaper or do you pay more. It also mentions something about still having to pay the prison local costs. I have a family member and was needing to set up for him to be able to call me but that $15.00 per call gets expensive. I'm not working and my mom has been helping me with the payment to receive a call. But, there's someone else that calls my middle son from the same facility. She got transferred there, first. Please, I hope you can help me.
