Will my airtel number change if i change my airtel sim card?

No, your Airtel number will not change if you change your Airtel SIM card. Your phone number is associated with your account, not the SIM card itself. As long as you are using the same account, your phone number will remain the same.

Yes, changing your Airtel SIM card will result in a change to your phone number. When you get a new SIM card, it comes with a unique phone number assigned to it. If you switch out your SIM card with the new one, your phone will automatically start using the new number associated with the new SIM card.
