    Hi All,

    I updated my oxygen OS last week and my 3G/4G network not working after update, with cellular data. Wifi is working fine but 3G/4G is not at all working.

    Can someone pls help to resolve this issue? Attached is the snapshot of current version OS and security patch installed on my mobile.

    Check your APN settings, completely remove the ones you have now and make a new one according to your carriers specifications.

    Something unusual. Let's try to resolve
    Sometimes simple solutions -

    Try Airplane mode ON/OFF & re try
    Check your network setting and preferred network
    Setting > wifi & internet > sim & network > preferred network type

    Try resetting your network setting
    If it doesn't work, you may contact your network carrier for support.

    While updating there may be possibility that some interruption may cause during network setting update .

    Thanks for your response.. I tried resetting APN settings many times and it didn't help. I also reported to network carrier, they're also looking into the issue.

    Is there any way to check if any interruption caused during network update and to repair it?

    Yes, this phone was bought one year back from Amazon.in official selling partner for OnePlus mobiles in India. APN settings are restored many times but no positive result.

    Hi All.... I sorted out that it's a sim card issue. I placed another sim card in my mobile and 4g started working. I'll change my sim card and try to see if the issue is fixed.
