    HeLLO sir

    I’m facing network problem in my Lenovo P2, The signal is going blank completely and coming back after 1 to 2 mins and this is happening only on sim slot 1 and sim slot 2 .There is no network in the mobile phone.
    There is less or weak network signal.
    Sometimes there is signal and sometimes there is no network signal.
    There is network signal for some time and then there is no signal at all.

      Clean the SIM connectors with IPA or Alcohol or Petrol and let it dry and insert the SIM back and check. If the problem is still there then change the SIM to another Service Provider and check. If the problem it still there then get the software updated.

    Most of the time mobile network problems occur due to the technical faults in your mobile network service provider.

    I have an Optimus 2 zone that has a broken antenna connection inside the phone itself. There are the two tabs that touch when putting the phone together that are for the antenna. I have found that hooking a wire to a tab and touching a leg on one of the circuits in the bottom left corner when looking at the back of the phone will make the 3g come on. Tried to solder it but it won’t respond now. Didn’t burn anything and the WiFi works perfect. I am using the phone now on WiFi. Do you happen to know where exactly I need to make this link so it will respond on this phone? Thank you.
