I can confirmed that this SGH III T999 supports 4G. After updating to Jelly Bean the 4G option just show up in Engineering mode. You can also find it out when trying to access data in instead of 3G it will show a 4G indicator.
Updated to Version 4.1 OTA a few weeks back, and recently went into the connectivity settings. Saw LTE among the types of connections under "Network Mode". I've looked at 3 different phones that were updated to the same software version and LTE shows up on all 3. Dunno if this is a glitch or what, but I'm hopeful.
my galaxy s3 t999 since rooted, the battery drained really fast. anybody knows why？
before root, i disconnected the phone from power at night, standby for over 8hrs. battery still have 95%.
after rooted, once disconnected from power, battery drains 10% within a hour when it is in standby.
Hey ! i ve the sgh-t999 and updated the 4.1.1 JB official version but then the wifi tethering hotspot doesnt work, any ideas please help!
This is an amazing phone, but not made physically too rich. Guts are awesome, though and this is what we need. There needs to be some type of RAM group get together against the carriers, though because the T999 loses nearly .5gb of RAM due to TMO's software that is a nuisance. Bad marketing, but awesome phone.

Awesome phone! I've been through 4 smartphones over the last 12 months and have found the one that will do what I want it to do. I upgraded to 4500mAh batteries and running much longer than the 2100 standard battery. All highend smartphones should come with minimum of 3000mAh and at least 2gb of RAM.
