I've got a VF 1210 - horrid little phone especially considering that the wireless data portal does not wirelessly send out the settings. Unfortunately there's little infomation to be found about this device either.
So for pxt I have -

MMS settings, VFNZ PXT:

MMSC: http://pxt.vodafone.net.nz/pxtsend
Data Connection: WAP Network (have tried internet and secure wap connection too)
Gameway: Wap 2.0 Gateway
IP Address: 172.30.38.3
Port: 8080
Encoding: Binary

Also in connection types have 2 options VFNZ Internet (I can browse the web fine) and VFNZ Gateway. This latter I've currently got on wap network although I've tried the other options there. The access point it live.vodafone.com. No username or password. Authentication type is none, primary and secondary DNS 0.0.0.0 No IP address

Was able to recieve pxts fine about a month ago...now nothing to the phone or pxtworld

Hope somebody else has the same phone who can help me with this!
