Here's a (long-winded) taste of my experience with getting a phone set up for use on Straight Talk with an AT&T SIM. Hopefully, this will help someone out there who's been searching everywhere for these settings in an attempt to optimize their speed and consistency of service.
I originally started my testing with a Verizon GS4 because I had a spare one in my office and, since it's unlocked, should have worked perfectly fine with the ST SIM. I created the APN as instructed by ST and had initial early success. About three or four hours later, data and MMS stopped working. A quick reboot fixed the issue but the problem kept coming back always with the same resolution.
I started digging around on forums for alternate settings. Eventually what I took to doing was experimenting with mixing and matching settings until I came up with a set that worked consistently over time and through reboots but even then data wasn't very fast. I knew that going from Verizon's LTE to HSPA+ was going to be a compromise but I wasn't very happy with how my tests were turning out.
Next, I scored a Nexus 4 off of Craigslist and as I decided that testing using a Verizon GS4 probably wasn't going to give me the best experience as to what I could expect when moving to ST as my main service. I was definitely correct in that thinking. Again, using a amalgamation of settings from various posts on forums, I've come up with an APN that works great. Fast (for HSPA+ 21) data speeds, consistent sending and receiving of MMS and voice and text. Listed below are the settings that I've found worked great for me and hopefully will for others who are still having issues.
Name: Straight Talk (just an identifier, can be whatever you want it to be)
APN: tfdata
MMSC: http://mms-tf.net
MMS proxy: mms3.tracfone.com
MMS port: 80
MCC: 310
MNC: 410
APN type: default,supl,mms
Everything else was left at their defaults. For reference, I'm in Northern New Jersey and I work in Manhattan. Not sure if these settings are region specific but I felt it worth mentioning.
So far I've been very happy with the Straight Talk service on AT&T's network. I've been finding that I'm getting service in places where Verizon's has been spotty such as in my office on the 52nd floor of my building. Typically I get anywhere between 1 bar of LTE to 1-2 bars of EVDO on Verizon on all my devices (Galaxy Nexus, iPad mini and iPhone 5; both of the i-devices are work provided so that I can support users of those platforms), and with ST I'm getting between 3 and 4 bars consistently of HSPA+. I think I'm going to like paying half price for mobile service.
