That makes perfect sense. You still will not be able to do OTASP. In order to do that, you have to go through the phone using QPST or the phone's internal Service Programming menus and make sure all of your MDN and MIN information is entered correctly. Typically, the MDN nuraber only appears once where it specifically asks for the MDN nuraber. All other entries should be the MIN nuraber.
Right now, only your MDN is registered with Cricket. You might be lucky and be one of those customers like me whose MDN and MIN are the exact same. But that doesn't mean your phone is set-up correctly.
