Free Caller Tune For Airtel Users:
All airtel users just follow my trick
1. first keep your balance below 1rs
2. then call 543211860
3. choose your favorite song
4. they will say 36rs for 30 days. Don't fear just choose and conform your song
you will receive conformation message like your callertune was activated for one day.
5. now your caller tune was fully activated.
6. next day you will get message your caller tune was cancelled due to insufficient balance. But actually you caller tune does not cancelled.. yeah!! this this perfectly working!!!
7. suppose if your caller tune was cancelled then reactivate it after that you will not get any caller tune related messages. Enjoy!!
