Where can I get my TAN from?

So I'm at Bank Volksbank.

And I've been using online banking for a long time. But recently I have a new cell phone and with a new device you have to register again. Everything went well at the beginning, then I got my VR Netkey a few days later, but now I have a problem. It says: The SecureGo-TAN would be made available to Huawei PRRA-LX1 at 21:20:49.

Now my question is where I can get it from because I haven't received any mail yet. Do I have to go to the bank then?

If you use a new cell phone, the VR-SecureGo must be registered again.
