Airtel - [ invalid sim card ] via OnePlus 9R Carbon Black

  1. shahkawnain , via OnePlus 9R Carbon Black , Nov 10, 2021 :
    [ SOLVED ] - check comments for solution.

    i restarted my phone and after restarting the device couldn't detect the single sim card that i use on my phone (Airtel) , tried rebooting it again but it doesn't help, it keeps showing that "Invalid Card - Emergency Calls Only"

    Did you test your sim in another device or this SIM card in another device?

    Other SIM cards are working on your phone?

    Reset your Network adapters, see if that helps.
    Settings, System, Reset Options, Reset WiFi Mobile Bluetooth.

    Restart the phone.

    If this doesn't fix it, has the phone been dropped or damaged in any way.

    bro i got it fixed, let me be clear, "the only 100% and guaranteed working solution is to buy a duplicate sim for your number", i searched up everything but at last to buy a duplicate sim was the only working solution, so don't waste your time searching for fixes on youtube, get a duplicate sim card, hope this will help you.

    Facing the same issue. Also it ain't supporting volte either. Don't know whether it's sim issue or the phone. I get the network when the sim is ejected and inserted back. I am damn sure it ain't slot issue cause when I switch the sim for different slot it's working fine. Only the slot with airtel is getting bugged.

    Backup and do a full Erase All Data factory reset on your phone. See if that helps.
