My Straight Talk APN is att.mnvo. I used the first group. Try the ones that match your Data APN from the APN profile and the APN from the settings from the Straight Talk web site.

Enter Your Cellular Data Settings
Enter your values. The screen shots show the values that worked for me. Make sure all your values are correct before you exit Cellular Data. My iPhone kept changing my CELLULAR DATA – APN, MMS – APN, and MMS Proxy values back to the ATT values while I was editing on this screen.
- Enter CELLULAR DATA – APN
- Enter MMS – APN
- Enter MMS – MMSC
- Enter MMS – Proxy
- Enter MMS Max Message Size
- Enter MMS UA Prof URL
This is optional, try it without it and if MMS does not work, add it.
- Tap Cellular
