OK after a lot of playing I have found something out.... The APN settings will not save if I change the MNC to 02, which my provider needs.
These are my provider APN's:
Name: Virgin Internet
APN type: default
These are the details for the MMS one:
Name: Virgin MMS
MMS proxy: 220.127.116.11
MMS port: 8070
APN type: mms
I have them saved now my having the MNC set to default which is 029, so of course they are there now in my phone, but not working.
As soon as I change the MNC to 02, they dissapear?
Weird as this was working fine yesterday.
