Can the BOP phone work with their cell phones? 

The BOP line from InmateAid is local to the facility the inmate is in. The inmate has to pay for each call from their cell coming out of their Trulincs account - they use their money is for calls, emails, and commissary.

The 15-minute call to your number is $3.15, the call to the local number is $0.90. You're saving $2.25 per call simply by using our local number (which rings to your long distance number). Our $8.95 fee to rent this number for a month is PAID FOR within four calls (save $9.00 in four calls). The inmates know how this works, they invented it.
