Samsung SGH-T139 "searching" after unlock with another compatible carrier SIM in it


    I recently unlocked my Samsung SGH-T139 from T-Mobile. I put the other carrier (Cricket) SIM to test to see if it will work and the phone is in a constantly "Searching" state. If I pop the T-Mobile SIM in it works. I checked to make sure it is unlocked all the settings show it is. I even manually hard reset the phone. When I try and do a manual network selection in the menu it refuses to connect to the Cricket network - gives me a "not allowed" error. Google searching hasn't been able to aid me in getting things working. Any help is greatly appreciated.
