    Hi and welcome.
    A few things for you to check:

    When you put sim card in your Tab, do you get any message?

    Any phone signal bars?

    Dial *#06# and write down the number (your IMEI as recorded by your Tab)

    Now take out battery and check that the number is the same.

    this is my IMEI when pressing * # 06 #

    Edited out for your phone security.
    The IMEI is the same.

    OK.
    Good news that your IMEI is correct.
    More questions however:
    1. Did you purchase the Tab from a mobile network or reliable seller?
    If no, then there is the possibility that the Tab has been reported lost /stolen and the IMEI number black listed.
    2. Did you have to modify the sim card?
    Check the contacts are not damaged.
    The contacts should be bright and shine. Rub gently with a pencil eraser if not.
    3. Are you putting in SIM card correctly?
    4. Can you try another SIM card, that you know us working?

    If all of the above are OK, then there would appear to be a physical /hardware problem with your tab.

    If you have lost your IMEI by installing another firmware, try returning to your original firmware.
