I was using vodafone sim card in my phone. It worked fine. Earlier there used to be problem of replacing it with other company sim cards, but I did not pay much attention due to busy life.

Yesterday, I changed sim card to Airtel and it worked fine but once I replaced it with my vodafone sim card again, it is not getting detected by the phone. Airtel still works fine.

The mobile network in settings screen gets frozen as shown in the attachment once vodafone sim is added.

I have tried numerous solutions available online including Factory data reset but problem still persists. Airtel works fine and Vodafone does not work.
