    Hi, my little phone has been working very well for many years but today, a dialog box appeared which stated:

    When I press "RESTARD" the phone shuts down and restarts normally. After that it operates normally for several hours or days when the same box appears and the sequence is repeated/

    Your SIM card could be faulty? Try getting a replacement from your carrier. Friend of mine had the same thing happening earlier this year, and the carrier replaced the SIM with a new one.
