Below is the Inmate Minute Revalidation Cycle.
This is when your Trufone, or phone minutes, reset.
You get 300 minutes a month.
Inmates could only use 15 minutes at a time. An inmate would have to wait at least one hour (I think, maybe 15 minutes) before he could call again. Once the inmate reaches 300 minutes, he cannot use the phone until the next month when his revalidation cycle begins.
When your number resets is based on the fifth digit of the inmates register number. For me my fifth number was “2.” So my minutes would have reset on the seventh of every month.
