Im on virgin mobile pay as you go and recently got a new sim a couple of months ago. Everything has been working fine but today I turned my phone off to save battery while I was at work and when I went to switch it back on it ask me twice for an unlock pin for my sim. The first time it asks is the pin I got when I received my new sim. (first pic) Then the next is my password pin (second pic) then it goes to a black screen and asks for my sim network pin which I have never seen before (third pic) but the PIN I got doesn't work for this. So I dismiss and get Invalid SIM card Network locked SIM card inserted.
