Working Straight Talk AT&T APN Settings:
Go to Android 4 Menu: Settings -> Wireless & Networks -> Mobile Networks -> Access Point Names
Here you should see a list of your APN’s which usually consists of only one. Mine was called Cingular. We want to reset the APN settings to the phone’s default and then edit that one to match the settings below. For reasons why I believe you need to do it this way instead of just adding a new APN please read the details below.
From the APN list:
Press Menu -> Reset to default
Now press the name of the default APN in the list to edit the settings. Set them all to what is below. If you have other options not listed here erase the entry or set them to “Not set”.
Name: Whatever you want. I used “st test”
APN type: default,supl,mms
Proxy: Not set
Port: Not set
Username: Not set
Password: Not set
Server: Not set
MMS Proxy: mms3.tracfone.com
MMS port: Not set
Authentication type: Not set
APN protocol: IPv4
APN roaming protocol: IPv4
APN enable/disable: APN enabled
Press MENU -> Save
REBOOT the phone.
Here are the APN settings that I found to work for my unlocked Doogee DG100 GSM phone. A lot of people including myself have had trouble getting MMS picture messaging to work on their unlocked GSM phones using an AT&T SIM card on the Straight Talk network. I have seen people having “luck” with it just starting to work on their next billing cycle after trying every possible combination of APN settings they found. I have about a month of service left so I was working on finding a solution before my renewal date. After reading through lots of comments and posts lingering around the internet on this subject I seem to have found a solution. Once I did it this way I was able to send and receive picture messages right away without using any other apps, or having to call straight talk customer service. Hopefully this will help others get their MMS picture messaging to work right away.
I originally tried using the settings above in a new APN that I created and told the phone to use. I was unable to send or receive MMS messages. I would receive a Download link in a text message, but when selected it sat there saying Downloading…for a while, then timed out with an Unable to download message. I finally reset the APN settings back to the default, then went in and erased everything in it. Then I put in the settings above and after a quick reboot I was able to send and receive picture messages in mere seconds. There was a note I saw in a post about making sure you leave the port options blank. Straight Talk recommends using port 80, but it is working on my phone from leaving it blank.
I started with a Sprint number which I ported over to Straight Talk. This seemed to be in common with a lot of people having this MMS problem. I think these settings will work for others too.
