  • My phone was saying invalid SIM then I did this and now it says No SIM Installed. Any help?

  • I did that and it didnt work.

    sorry!

  • @RCoster47 I think he means re-place it back into the sim slot and it will work... (I think)

  • Do you mean going to network operator for sim replacement or what?

  • what do u mean by replace it?
