Wanted to add a custom caller tune in reliance that I have change my number and my new number is 98XXXXXXX but it was so sad that reliance is currently not allowing us an option where we can have custom caller tune. This feature is available in BSNL, Airtel and many others but still Reliance fails to offer this service.
Anyways I have shifted.
