She will not know about the new number to dial until you or someone else lets her know. We will provide a coupon code for you to use in letting her know. If you can get the number to her through a staff member you could try that. It is not 100% effective. The concept of the service is that it is the number that provides the discount through the company with the contract for the facility your inmate is incarcerated in. We do not replace them, we know their rates and which numbers will provide the lowest possible call price. If you would like to know more, send us your telephone number and the name and state of the prison/jail and we will give you an honest estimate of the possible savings. If there are no savings, we will let you know that, too.
