    Sir i have Infocus M-810 having airtel 4G sim.Last from 3 days facing problems of no network issue.kindly suggest the solition

    • Santosh Das Santosh Das says:

      There can be several reasons for this. First of all Remove the SIM and check both the SIM and the SIM Connector with IPA or Petrol (If you don’t have IPA). Allow to dry and again Insert back the SIM and check. Otherwise all you can do is RESET the Phone and Check. If the problem is still not solved then Flash / Reinstall the OS.

    I’m facing network problem in my micromax Q465, 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.

    Sir , recently i got my micromax android a1 AQ4502 flashed to stock ROM , android 5.1..SINCE THEN MY PHONE ISN’T SHOWING ANY NETWORKS AT ALL . However it is reading the sim card..i’ve tried everything possible like checking my tata docomo sim in different phone (it’s working) , putting another working sim in my phone ( no networks again), Factory Reset, upgrading my phone to android 6 , got the phone’s antenna checked but nothing has worked . also Jio4gVoice app which was working prior to flashing is now not been able to configure with jiofi device after that..To sum up I would say i’ve not been able to place/receive calls neither from android calling app nor from jio4gvoice .

    Please help me solve the issue.
    Thank you

    • Santosh Das Santosh Das says:

      Check the Network Setting. Is it 2G, 3G or LTE in the Setting? If everything is OK, then Clean the Board with IPA or Alcohol and Assemble Back and Check. If it still doens’t works then you may have to change the Network IC.

      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.

  43. Avatar Sinzo says:

    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.
