Hi, a_g. Thanks for contacting us. Unfortunately, Boost Mobile is a prepaid service that charges you for your cellular airtime - we don't provide a service to assess and bill you for additional fees and charges generated from collect calls. Some correctional facilities allow people to make prepaid calls from the facility. You might want to contact the facility to ask whether they offer this option. But if the call comes in as a collect call, unfortunately, you won't be able to receive it on your Boost phone.
