Can I transfer Talk Time balance

You can not transfer talk time balance from one number to another or you can not transfer it from Individual talk time to master talk time.

Once you removed the Virtual number from your account then you will get the credit for the remaining talk time of that individual number and the you can use it on buying more numbers or add it in Master talk time.

Without removing the number we can not refund you individual talk time.
