I took my SIM card out of my samsung galaxy s4 and put it in my new samsung but the SIM card comes up "invalid SIM card"Network locked SIM card inserted.. what can I do to fix the problem? thanks
It's the same phone samsung s4,I bought it off a guy who said it was unlocked.When I put my SIM card in it and turn it on "SIM network unlock PIN" comes up. He said the PIN was 6 sixes but when I tried using the number he gave me to unlock it doesn't work..
from a private seller,he bought it from Future shop...So I can't do anything until he gives me the correct PIN to unlock it?
