    that just means its stored. It came on and went off at some point.

    clear it with the UG and see if it comes back.

    you can always put a sim in and never have that problem.

    ahhh I see thanks for informing me. so if I clear it with the UG it will come back eventually? It doesn't cancel it for good?

    I don't think so. If there is a problem you'll probably get codes again.
