Bitfinex Withdraw Problem

[xga676]

Hi, I have a problem to withdraw Bitcoin from Bitfinex.
When I try to withdraw I am asked for an SMS to be sent to get a Code. When I confirm sending an SMS an error occurs that SMS could not be sent to that number. When I try to change Settings of SMS and 2-Factor-Authentication  I need an SMS-Code to confirm that action, which I
don´t get. Has anybody had this problem before or does someone know a solution for this?
Thank You.
