It varies. I got this phone for Black Friday online. Straight Talk staff told me it would run on Verizon (I called before I got the phone, and then when I got it I call again and gave them the ESN to verify it). I transferred my number and minutes over to it and had instant regret. Poor signal, internet was slower than dial up speeds! A tech guy at my work looked at the build number in the menu of the phone and was able to somehow find online that it was working off sprint based on that build number. A good friend of mine got the same phone, same price, at black friday but got it in a store about an hour from our home. His is running off Verizon and he has no trouble out of it. I would suggest buying it in-store nearby. Chances are, your walmart won't sell it if it doesn't work in your area. I wont be ordering anymore phones off walmart.com and i definitely don't trust the advice/information from the employees at Straight Talk. I got my money back for the SIII and switched back to my old phone.

Again, for those reading this question, be careful when ordering a Straight Talk SIII as there are TWO versions.
This one is on SPRINT and is a true 4G LTE phone. This phone's model number is S960L or will have the code on its box LTE-S.
The one that runs on Verizon has the model number of S968C ...is CDMA and runs on Verizon but will be limited to 3G speeds.
If you are order the phone featured on this page, it will be Sprint powered.
If you can't determine for sure what the model number may be, the Verizon version will make no reference to being LTE where the Sprint version will.
It is CDMA. Runs on Verizon.

troy, this particular phone is the S960L and will be on the Sprint network. It is true 4G LTE.
Straight Talk has another version of the S III that does run on Verizon but is limited to 3G only. Currently, it is priced $100 more than this phone at $399 and the model number is S968C.
You can find the Verizon version (S968C) here (copy-and-paste):
for the white model:
for the pebble blue model:
Straight Talk does not have an S III on T-Mobile. However, the new Straight Talk Samsung Galaxy S4 does use T-Mobile.
