I get lte. It is the lte bands that are in use but because of the aio proxy it is throttled to hsdpa+ speeds of 8-9mbps.
But since with every other carrier on my tmo device [att, straight talk, net10, I got only hsdpa+ anyways, which obviously cannot be because I lack an antenna because the att note ii and tmobile note ii have all the same antennas.
Tmo
GSM:
850, 900, 1800, 1900 MHz
UMTS:
850, 1700/2100, 1900, 2100 MHz
FDD LTE:
700 (band 17), 1700/2100 (band 4) MHz
[The lte is not listed on many specs because it wasent advertised at release, but it is there and was unlocked with a new version of android. [4.1.2]]
At&t
GSM:
850, 900, 1800, 1900 MHz
UMTS:
850, 1900, 2100 MHz
FDD LTE:
700 (band 17), 1700/2100 (band 4) MHz
] I am happy with that speed as the trottle on the spft cap is higher than any other carrier and there is no hard cap like with att go phone.
So as you can see it should work, regardless of what band lte at&t is using in your area provided your device is similar to mine. [I cant remember whst tmo device u have of hand]
I cannot run tmobile because one of their non lte frequencies interfears with base opporations near my home.
However when I was in salt lake city last march, I got on tmobile for a month because of the isis sim was in that area and come to find out so was the lte rollout on tmobile and low and behold lte speeds of 21-30mbps [if memory serves for the max, I know it was 21mbs usualy.] depending on time of day.
Same icon, on hsdpa I dont get a 4glte icon I get an h or on hsdpa+ an h+.
Also looking in hidden menus and playing with the connections I am sure its realy running lte on aio.
I have not run this device on att post pade tho, u may have better luck there.
