Galaxy Nexus + Straight Talk + AT&T + MMS APN Settings

If you are using a Galaxy Nexus on Straight Talk with a AT&T provisioned SIM card and having issues with sending and receiving MMS, here are the APN settings that should work for you.

The Galaxy Nexus that I bought through Google Play had a Cingular APN already on it. Delete it. Or at least write down the settings just in case everything breaks on you. And then delete it.

Add a new APN with exactly these entries:

Name: straight talk (or whatever you want it to be)
APN: att.mvno
Proxy: proxy.mvno.tracfone.com
Port: 80
Username: Not set
Password: Not set
Server: Not set
MMSC: http://mmsc.cingular.com
MMS proxy: 66.209.11.33
MMS port: 80
MCC: 310
MNC: 410
Authentication type: Not set
APN type: Not set
APN protocol: IPv4
APN enable/disable: APN enabled
Bearer: Unspecified

That should be it.
