    I have a Galaxy S4 that wouldn't read an ATT sim.....

    I was hoping that unlocking it would allow me to bypass the issue by using a different carrier..

    I put the new sim in and it said INVALID SIM and then prompted me for a network code. I pushed DISMISS per the instructions, but it still wouldn't read the SIM...

    Is there any other way of confirming the UNLOCK did work besides the SIM card??

    Thanx
