How To Find APN Settings.

If you're running stock Android (or a custom ROM), then go into Settings, tap on More at the bottom of where it says Wireless, then tap on Mobile Networks. You'll see an option called Access Point Names near the bottom.

If you're running Touchwiz or Sense, then I'm not exactly sure if the option is in the same location.
 
I've done that as advised but when I click on Mobile Networks there is no Access Point Names option. Yes, it's stock Android.
 
I just recently got this phone from Virgin Mobile, and I'm having the same issue. MMS is the ONLY thing not working, and I cannot seem to find this "Access Point Names" that everyone keeps telling me to edit in order to troubleshoot.
 
I'm having the same issue with my Sprint Galaxy S3. APN settings do not appear anywhere under mobile networks. Any insight to this issue would be appreciated.
 
Settings -> More settings -> Mobile networks -> Access Point Names
