Nokia Lumia 920 APN Data Settings Net 10 Wireless

Here are the settings for a Nokia Lumia 920 on the Net 10 Network. 

Go to Settings > cellular
Tap edit internet apn and under APN type tfdata and leave everything else blank and Save
Tap edit mms apn and type in this info
APN: tfdata
WAP gateway (URL): mms3.tracfone.com
WAP gateway port: 80
MMSC (URL): http://mms-tf.net/
MMSC port: 80
Leave everything else blank and Save
Now restart your phone, verify these settings and give it a couple of minutes, and everything should work just fine.
One of the features you don't get is visual voicemail, but fortunately there is an app for that... I downloaded Magik Mail and it's very good.
Other than that, everything works fine.
Good luck!
