    Invalid SIM problem in China feature phone


    I have a cheap single chip Chinese feature phone, it was not used since purchase and it looks fine if I turn it on, but problem is that it is not supporting my tata docomo sim. It uses a micro sim, that sim works on my other sony phone but not working in this one. When I search for network then it shows all network, also when I turn on the phone with sim, it shows mchek processing, so it means it tries to connect to docomo network but network is denying. What could be problem and what solution ?

    Friend, you got a phone with invalid IMEI, you may contact local phone repair shop and he may update new IMEI in it which is valid, they generally use IMEI of old discarded phones, should work for you.
