New N211 + Vodafone. Registered but cannot send UDP

Hi,

I have just bought a device with Vodafone NL SIM. I am registered OK in Ireland.

Should it work? Do I need to whitelist by IP address I am using? If so how can I do that?

Just to clarify. I can send to the sandbox but I need to send to my own server directly. Do I somehow need to provide the IP address of my server?
