A trusted friend sent this alert bordering on some persons listening to one's phone conversation, or spying in manner.
That I should deactivate all call forwarding by dialling on daily basis or even before I make first call of the day or when one want to make calls bordering on financial transaction.
1: #61#
2: ##002#
Though when I dialled ##002# the response was Call forwarding successfully erased. But I never set up call forwarding in my device at any time.
Who are aware of this?
