Re: Samsung Galaxy S4 APN Straight Talk settings HELP
So here is the little trick I happened to stumble across reading a few threads about people having Straight Talk ATT APN issues.
The Magic Key:
YOU MUST EDIT THE ORIGINAL DEFAULT APN YOUR PHONE GIVES YOU. Editing or making the original default APN correct is the key.
Why this is??? I have no idea... However I can tell you that Straight Talk really doesn't care or have the motivation to fix this due to them not really wanting us on ATT anymore anyway. I believe somehow the phones are holding what they have in the default as the only APN that works no matter what second, third, forth, etc....APN you select.
Tmobile Samsung Galaxy S3(JB 4.1.2) - I spent all of about 2 minutes editing my Unlocked Tmobile Galaxy S3's default APN it gave me. Mine worked perfect in 2 minutes because Samsung allows this.
Tmobile Optimus L9(JB 4.1.2) - I spent just about all weekend slamming my head against the wall on my wife's Unlocked Tmobile Optimus L9. In the infinite wisdom of LG they decided to be cute and lock down the default APN setting from being editable. I tried every secondary APN settings on the net I could find. None worked. She did have internet, just no MMS.(Her default APN was partially correct which is why I think she had internet only.) So I had to friggen go as far as rooting her phone and editing the apns-conf.xml file located in the \system\etc folder with the proper settings shown below. Doing this corrects the default APN the phones sees for what sim card is in it. For tracphone on hers I believe it comes up under "Media Net" for whatever reason.
Once you do the edit I have listed above, reboot the phone. Add in a temp fake second APN, then get back to the main APN screen. Once you are there hit the menu button and select reset to default. Magically the new edit you did to the apns-conf.xml file will show with your Straight Talk edits. After that everything will work!
Even if you deleted out the original default APN the above step of reset to default will bring back the original one so you can edit for say on a Samsung S3. Remember editing or making the original default APN correct is the key.
