How do I set up my APN for Delight mobile (Netherlands)?

[AC Question]

I've been trying for a few days now but it's not working with just filling in the name, APN & APN type, MCC and MNC.

It said the DNS isn't working (something like that) and now, after I added the APN protocol, APN roaming protocol, authentication type and the username guest, password password, I made some progress. Now there's only a problem with the proxy server or so.

Would anyone like to help?
