I had the same problem with my TRU9585, And it appeared that my base unit plug was loose. I unplugged everything then plugged back in and that fixed the problem.

    When your TracFone is turned on you may receive the message "SIM card registration failed", "Unregistered SIM", or "No Service" because your phone has not yet been Activated. Please disregard this message, it will disappear once your phone is Active.

    Whenever SIM is inserted in Handset it shows "UNRegistered SIM" & that SIM works on all other Mobiles.

    is it an unlocked phone? The "Unregistered SIM" message means that you're using a SIM card for which this phone is not intended. You will need to have the phone unlocked and it should work.

    If it is a new fone then Phones are not shipped activated. You should look in the box for activation instructions. Read and follow them.
    is that a prepaid sim then probably the sim has been deactivated...

    How to REregister handsets

    You can unregister your phone without being in the cradle, but to re-register them, just put them back in the cradle.  After being unregistered, they will automatically re-register once they are put back in the cradle of the main base.  Try setting them back in the base cradle to re-register, and hopefully that will work for you.

    I'm not sure exactly what you're trying to do, but here's the rundown of what I can get from your post.
    To register (assuming the phone is not currently registered): place the phone in the main base cradle.  It should automatically register itself to the base.
    To unregister:  I can't tell you exactly how to do this because I don't have my phone sitting infront of me, but I know that it is in the main menu on the phone.
    Using the end call/pound key: Pressing this combo and holding for about 5 seconds (possibly much more - it's taken me 10 seconds before) will THEORETICALLY let you reset the base.  I have never gotten this to work before, but the menu once you hit this should be fairly self-explanatory.  The reset I believe resets the base to factory, and unregisters all phones.
    Hopefully this helps.  If not, repost and I can most likely help you out (I've got the same phone).  Best of luck!
