Yes. If your situation changes, whether your inmate is transferred to a different facility or you need a number configured for a different location, InmateAid can set up a new line for you. Email aid@inmateaid.com with the updated facility information and the team will establish the new service. In situations where the original number did not work as expected, InmateAid has offered the first month at no charge as a goodwill gesture.
On the refund question more broadly: when a phone line is issued, InmateAid incurs a real cost from the carrier on the first of each month for every active line, regardless of whether it gets used. That makes refunds a loss rather than a simple return transaction. The team tries to accommodate situations where the service did not work as intended, but the practical solution is usually a replacement or transferred line rather than a cash refund.
The best path forward is to email the team directly with your new details and let them sort it out from there.
