What are the contents of the MMS APN fields?

[AlanBundy]

I have a Nokia Lumia 640 XL running Windows 8 with a Virgin sim card and accessing a Virgin 4G signal. Currently, I cannot send or receive multi-media content in text messages. I understand that I have to edit the MMS APN fields in settings. Initially, these were blank. I've looked online to find out what the content of them should be and typed these in for Virgin 4G, but it did not enable multi-media capability. I also tried EE and Vodafone contents, as Virgin says they sometimes use them, but still no success.

What content should I fill in? Here are the fields:

APN
Username
Password
Authentication type
WAP gateway (URL)
WAO gateway port
MMSC (URL)
MMSC port
Maximum MMS size
IP type

Thanks for your help.
