    Check: Connections / Mobile Network. There should be a check in the box and a Green Icon.

    That can happen when the battery goes nearly dead. It needs to be turned back on manualy.

    You can only make emergency calls.
    That is a lot of help, but it doesn't explain why you are stuck on Emergency.

    I have heard, if you dial an emergency call, it will remain in emergency mode so they can call you back for more information. Could that have happened?

    About Emergency Callback Mode

    About Emergency Callback Mode
    When you end an emergency call, the BlackBerry device enters Emergency Callback Mode. This mode enables the operator to call you back or determine your approximate location. Depending on your service provider, Emergency Callback Mode is active for five minutes or is canceled when you make a non-emergency call.

    In Emergency Callback Mode, you cannot send and receive messages or browse web pages.

    Your device exits Emergency Callback Mode at any time if you make a non-emergency call.
    Try making a normal call.

    There is another possibility, if your SIM card is not present, or if it can not read the card, it will display SOS mode.

    Use a pink rubber eraser to gently clean the Gold contacts on the SIM card and the 6 Gold contact points in the mounting clip.

    If that does not fix it, there could be a carrier cause. Best to phone them to make sure your account is still active.
