Would it be a problem if the previous owner had registered the pin and switched to a different plan?
Yes, if the PIN is still registered on the previous carrier, it won't register on another.
You or your friend need to call the previous mobile provider and have the PIN removed from that account.
THAT will keep the device from now being registered, and the Data Plan being provisioned to your device.
