SMS two factor authentication error: "SMS is not sent"

I have set up sms up and can send an sms in the sms center.

But when I choose the authentication method to be sms I get the following message when trying to log in “SMS is not sent. Please contact your administrator”
What must I do in order to set it up properly.
