Welcome to the all-new Windows Central Forums! - We're still moving some things around, so you may see a few quirks here and there, but we're working on getting things fully completed as soon as possible. For now, take a look around, and if you run into any major issues, please let us know in this thread!
As I understand it, there are two distinctly different hardware versions, the SGH-T899M, which does support LTE, and the I8750 from does not support LTE but only a max of HSDPA 42. The I8750 was being sold unlocked by Expansys for a while, where as the T899M is the one sold by the Canadian carriers.
The hardware for the LTE version has a different wireless chipset...Do you know if this SGH-T899M differs from any other version, in case of hardware. Because if the hardware isn't really different from the other versions, it must be a software limitation. I've always been wondering why Samsung did not include 4G in every model. The Snapdragon chip they used supports it, which makes me think it's a software limitation.

Hi, Antonio. I don't think the i8750 model is capable of LTE. You would need the SGH-T899.How are you running LTE speeds? I have an unlocked GT-i8750 running on T-Mobile here in philly and it only gets up to HSPA+ It cant be something with the signal because my HTC Radar got 4G LTE with no problem
After extensive searching I'm 99.99% certain that there is NO different hardware for either versions. How do I know? Well I've found a secret menu in the phone that you can get to by ##3282#, after that you can get into another 'dialer' by pressing the back button once. Then when I enter *#8888# and press number 4 in the new menu another menu pops-up. Pressing the on-screen button saying 'Back' brings you to the root menu where you can select 3 for LTE tests, after which you can select 1 for the debug view. It gives me all sorts of information;
RRC: IDLE, Band1
RX 10637, RI:-91, CID: 8b3af
TX: 9687, PSC: 279
Eclo: -8, RSCP: -99
VOC: FR FR FR, 0
CQI: 0, Sam: 0
I think ******* Samsung just disabled 4G on most phones, not sure why, but one day I'll find out to how to hack it. Also I think the RI and RSCP values have something to do with the reception, probably some sort of dB value. It changes when I move my phone around and go into the debug menu again.
