Hi friends,I found a good trick to transfer the amount in special balance to normal account.
I (my friend) personaly checked in karnataka and kerala.
Its works. Into the trick, first recharge with any special recharge for full talk time starting form Rs. 9,
if you dont have any special balance.
After recharging follow this.
First dial *595#.
An USSD alert will display like Service not active.
Now you done.
Then check your balance. Rs. 1 will be moved from your special balance to main balance.
Do the same step for transferring the remaining special balance into the main account(For me -1 is possible in my special balance, so that i will get special balance + 1 rs to my main balance )
