voice and text
You can always see the number of the person calling you on the display of your Airtel mobile phone.
When you see who is calling, you can decide whether to answer or not. If you don't want to take the call, it is automatically transferred to your Voicemail. That way, you can reply when it suits you.
The service is free and is already set up on all Airtel mobile phones.
How to withhold your identity
To stop your number showing permanently, please call Customer Care and ask them to set up this option for you.
