Call forwarding problem !!!

[G.One]

My n900 automatically turns on the forward option ! I turned it off by going in to setting>phone.. But it again turns on
I even flashed my n900 but no use :(
Can some one help ?

Totally unrelated to N900.

This is some standard feature from network providers.
What country? What provider?

This feature is about to enable SMS notification for callers/callees.
May be en/disabled in your mailbox directly. Even after deleting the network will set a call forwarding (normally for "out of reach") to a specific number.

+1 to that, settings in settings->phone do nothing for my network, call the customer support to sort this out
