I was locked out of Vodafone forum because I complained too much, so I come here.
I have used this APN direct.Vodafone.net.nz for 4 months without any problem. But it suddenly stopped working last week. I thought I need to call the customer service people, but I decided to try changing the APN to the original www.Vodafone.net.nz, and my internet worked straight away.
Because www.Vodafone.net.nz can block certain inbound connection, some of my apps doesn't work on that APN. But the Direct one works with all my apps.
I don't know if the issue applies to the celltower in Rangiora only or not. I'm using the Novatel Mifi bought from Vodafone store.
