2) Once you enable the Developer Mode, you can edit the settings.
Do these steps.
If you have done them, do them again.
this is NOT to ADD a new APN. If you think it says that you can't read. It's saying to EDIT the APN settings.

after that in settings the connections tab hit more networks-->mobile networks-->apn setting and hit menu button and add the needed apn setting and hit save...

I was able to get everything working including mms and 4g hspa+ with my at&t straight talk sim without rooting or anything except these steps.. works great!

But once he activates the Developer Mode -- as outlined in that forum post -- the instructions work to edit the stock APN, right?
Clarify what you mean by this part?
With S4 you still need to toggle it on, it defaults to off.
I still can't edit those settings even if I'm on developer mode, so my ONLY choice is to add a new apn!
I came across that threat as well and didn't work for me! The reason I'm here asking questions is because I've been looking for 2 days and I didn't find anything so I figured I would ask you guys. You are talking to me like I'm a first time android user and is not like that, I CAN'T edit or delete original apn even if I'm on developer mode so my ONLY choice is to create a new one!
When you see THIS below (or something like this) -- what happens when you CLICK on the APN? Does it open up?
When it OPENS UP, does it say "EDIT Acess Point? This is an S4 APN below.
what happens when you CLICK on a field? Does the keyboard come up?
When the keyboard comes up, does it let you type?
After you type, can you go into the menu options and SAVE?
this is NOT an S4 but ALL Androids do this.
When I click con that "att phone" it opens up, after it opens up and I hit menu there my only choice is "discard" I see all the fields on gray, if I click on a field nothing happens (all fields are gray) Keyboard doesn't come up....
