    Default Invalid Sim Card ( BSNL sim card ) With micromax 310G

    Hi there,

    Recently purchased Micromax 310G 3G data card. I have inserted my BSNL sim card. The application which connects to internet shows a message "Invalid Sim". This sim I had already used with my 3G mobile phone. Earlier the sim was migrated from 2G to 3G. Right now the GPRS plan of Rs 270 is activated on the number.

    I did some search for this problem. People did face similar problem with other operator sim card and they went for unlocking the sim with some code. I wanted to try this but the problem is my dialer application does not show any option of unlocking.


    1. Why there is problem of invalid sim since it being a BSNL one. ?
    2. Where does the option unlock in the application appears. Can anybody send me the screenshot of it.
    3. What version of Micromax dialer you people are using to connect to internet.

    Thanks
    Regards

    Thanks mickey for the reply.

    Yes its working fine over phone.
    BTW are you aware where do we get the option in micromax dialer to unlock the sim. What will be the unlock code for it. ( i am assuming that my bsnl sim card is also treated as same as other operator sim card)

    My data card is has bsnl 3G logo on it.

    As such i will be visiting the seller in the evening thought of checking with forum first. I am very much sure, the seller will not be aware of the solution.

    I bought it for Rs 2300 from a small shop in pune.

    Offcourse i will check my problem with the seller first. Then go ahead with unlocking it. I am browsing thru the forum and found people talking about nck code. Are you aware of any software where I can get this nck generator.

    BTW what data card are you using as of now.?

    Thanks

    the same micromax 310 ..
    well about NCK code, the shopkeeper is the best person to deal in, because we are not advanced users.. yes it is there..

    btw, try to buy a Huawei 21mbps card if you can for a little more money(if he can exchange-) as micromax has some disconnection problems due to overheating.. (though personally i never had but people report here)...
    see that if he can exchange.. one must upgrade if its ok

    ------------310G HELP---------------

    when i opened help, the most appropriate cause was hardware problem..

    p.s:- one must check thoroughly and physically in the shop before transaction happens.. because in India, even packed items could malfunction.
