I am currently in the US. Google translate, not helped by poor data connection, is unable to handle the information on this forum so although my problem has been raised already, I can't find the answer. I am 'not registered to a network' - this is the message when I try to call. I need to use my Dutch Vodafone sim urgently to receive a security code from my bank. I cannot call from my American phone, the Fb browser site wouldn't allow me to message for some reason, you seem to be invisible if searched for in the Fb app, I don't use Twitter, and short of sending a handwritten letter I'm out of options. Can you help?
