I am on AT&T and the reason I bought this phone was because, according to the specs in the FCC site, it has LTE Band 17 (which is the most common one for AT&T).
I was only getting 3G (HSPA+) speeds. I followed the following procedure to enable LTE for data and still be able to place/receive phone calls:
Do this at your own risk
Open the dial pad
Type: *#0011# to enter Service Mode (Be very careful with what you do here)
Note: You need to be rooted for this to work
Once in Service Mode, do the following:
Tap the menu button and tap Back
Tap the menu button again and select "Key Input" and enter an upper case Q and press OK
Tap the menu button again and select "Key Input" and enter 4 zeroes (0000) and press OK
Wait from 5 to 15 seconds. You'll see the Main Menu
Choose option [2]: UE SETTING & INFO
Choose option [1]: SETTING
Choose option [1]: PROTOCOL
Choose option [2]: NAS
Choose option [1]: NETWORK CONTROL
Choose option [4]: BAND SELECTION
Choose option [4]: LTE Band Preference
Choose option [7]: LTE ALL (Or you can choose band 17 instead)
Tap the menu button and choose Back (Don't press the back key)
Tap again the menu button and choose Back
Choose option [6]: LTE/WCDMA Mode Only
Press the back key to exit
And that's it: You now have LTE and calls if using AT&T. This won't work with TMobile.
If you reboot your phone, you may need to repeat the steps.

I am confused. I am also on ATT - I bought this phone back when it first came out. All I did was add the ATT APN and then I was able to get LTE just fine. I didn't have to do anything like you described.
So - are you saying you added your APN and still had to go thru all of those steps?

That brings up another question - If I am getting LTE now - does that mean I am already getting data via that Band you mentioned ? Or could it be that I am getting it from some other band? (forgive these noobie type questions - I really don't know that much about this)
and is there a difference between the speeed you can get from any of the different bands?

Try this free app to show you what LTE band you are using
https://play.google.com/store/apps/details?id=net.simplyadvanced.ltediscovery
Most likely if you are on AT&T is band 17.
The higher the frequency the most difficult it is for the signal to travel farther or into building. You'll better results if you are receiving on 700MHz than 2600MHz, but that is determined by your carrier (although there are ways to manually change it)
Yup my AT&T LTE bands weren't activated as well. Had to go through these steps and they worked perfectly!

Thanks for the informatino - I had no idea that some phones had problems connecting to LTE - I personally never have had that issue with any of the TMOBILE PHONES i have used on ATT (Note 3 and my S5) but its good to know this in case it ever happens with a future phone.
anyway, for grins and gigglesI got the app suggested - but I can't see in the app where it says what band I am using?
I attached a screen shot - can you tell me what I should be looking for?

Thanks - Got it - and you were right, Band 17
Hey Miscom. Thank you for the post. I am considering this phone. I am wondering if this phone is fully compatible with all LTE At&t bands? I copied the At&t band info from a post on another forum and pasted it below. I assume that it is correct.
At&t LTE Bands
4G HSPA and HSPA+ use 850Mhz(Band 5) and 1900Mhz(Band 2) bands but it all depends on area if they own a license. LTE uses Band 17(700Mhz), Band 5(850Mhz), Band 2(1900Mhz), Band 4(1700/2100Mhz) currently.
It appears that Band 4(1700/2100) is missing from the SM-G906S specs.
SM-G906S LTE Bands (Source: http://28mobile.com/Product/View/68834/samsung-galaxy-s5-prime-lte-a-sm-g906s-k-32gb-black-4g/)

You are correct: Band 4 is missing. For AT&T only band 17 is available in the G906S.
Band 17 is the main LTE band for AT&T. I traveled by car a few days ago from Tennessee to New York and except for a few places, I got LTE most of the time. Never saw E, only 3G (AT&T's 4G) and LTE.
Same here I have LTE pretty much 99% everywhere I go. I'm on AT&T as well.
That is good news. Do you guys know if there will be ROM support by cyanogen for this phone?
Also. Where did you guys get yours?

What APN did you use?
I found this on AT&T official website,
Your device will need to work on one of these GSM network frequencies:
AT&T Multi-band GSM
UMTS, LTE or unlocked Multi-band GSM - 850/1900 MHz
UMTS - 850/1900 MHz
LTE Band 2 - 1900 MHz
LTE Band 4 - 1700 MHz
LTE Band 5 - 800 MHz
LTE Band 17 - 700 MHz

your phone needs to W-CDMA or UMTS capabale to support 3G. if you are using WM 6.1 it should also give you the option to automatically select Network type and GSM/UMTS band depending on the network you are in.
to check your options goto start-settings-Band tab- and look under network type and Band if you see WCDMA and UMTS settings there then your phone will use those when in a 3G network.
UMTS bands are typically 2100 or 1900+850
Again all of the above info is freely available on the internet..just google for 3G and you'll be well informed on the subject
Thanks, Prabh.
But I know the Band information tab in Phone setting and I selected;
Network type = Auto
GSM/UMTS band = GSM(1900+850)+UMTS(1900+850)
What I want to know is...Which frequency (1900 or 850) I am currently on.

I am going to switch over to Touch Diamond or Touch Pro.
US Diamond/Pro supports UMTS 850/1900MHz but I need UMTS2100 as well
because I often travel to Japan for biz trip.
I know UMTS1900 is widely operated in US but if my area (I live in NY) is in UMTS850
coverage, I will go for Aussie version which supports UMTS 850/2100MHz.
I'm planning on getting a Meizu Mx4 Pro to play around with but it only supports the 1900mhz band for 3G. I am on T-mobile and only the refarmed areas use the 1900mhz band. Is there a way to test with my Nexus 6 via some app or settings whether my area is using the 1900mhz band? I also read somewhere that if you get T-mobile LTE you are in a refarmed area as the 1700mhz AWS band is being used for LTE instead of 3G and the 1900mhz has been refarmed there for 3G instead, although I am taking the statement with a grain of salt for now.

I think that will tell you what frequency you are on, but not allow you to set a specific frequency. To my knowledge there is no way to do that on the Nexus 6 yet. Could be wrong?
The data service menu is missing on this phone.
You can get into the Field Test Settings, but I highly recommend not jacking with anything....I went in there for a look see, and when I backed out I was somehow in GSM mode and could NOT get back to CDMA until I did a complete nuke and repave of the Google Factory images to get back the CDMA network.
YMMV...but be warned

If multiple bands are available in an area, LTE Discovery will not show you the additional bands, only the one you are using. You'd need to use a service screen to manually set your phone to a specific band, which is not possible currently. Maybe OP can chime in with more detail.

I don't think we need further explanation from the op. It seems clear to me that he is trying to see whether his area has been re-farmed to band 2 1900mhz or has been left at the usual band 4 1700mhz.
Using LTE discovery will show him what band he is connected to on his phone. If it will be band 4, than his new phone he is trying to get will not have LTE. Although sometimes both bands are available so in that case he would have to have the ability to switch.
Switching bands is possible through phone info screen accessible using an activity launcher of some sort. Once you're in phone info , hit menu and select radio band. But I don't think that's what he initially was looking for.

Perhaps, but there is no known phone accessible screen found on the Nexus 6 that allows band selection. Some have used this to determine whether certain bands are starting to be rolled out in various areas.
Edit: I'll qualify that the menu exists but does not allow a selection of all LTE bands. I can only select US, 6 or 7 on my phone.

So if I run LTE discovery, it shows LTE band is 4, if I go into *#*#3282#*#* it shows bands 12,25,26,41 nothing else..... Also all 4 of these bands have a priority setting of 0....If I go into *#*#4636#*#* and go into the menu , select radio band...it shows USA Band, Band Mode 6, Band Mode 7 and Band mode 15 which is weird no indication of band 4 anywhere..... I read that Telus's fastest LTE is on Band 7 but I have no clue how to get there.... I am downtown Calgary so there should be coverage... any suggestions?

Unfortunately the AT&T s6 doesn't have support for WCDMA 900 however GSM 900 is supported. You would have to put your phone is GSM only mode in order to get that. For GSM only mode, in your dialer type *#*#4636#*#* > Device information > There should be a menu that says select preferred network type, select GSM only. This will be much slower than WCDMA but you will have a better signal.

I have a Verizon S8 that I flashed with the XAC firmware and so I'm at XAA/VZW/VZW after enabling all bands. However, even though the entire bay area should be blanketed under band 12, I have not once connected to band 12. I'm always on band 4. Has anyone with a original Tmo S8 ever connected to band 12 in the SF bay area? You can check using LTE Discovery or SignalCheck apps from the Play store. The whole reason for me to go through the trouble of flashing the non-VZW firmware was to ensure I would be able to access band 12 but doesn't seem like that worked.
I'm sitting at home on my T-Mo S8 in the SF Bay Area and I'm on Band 4. I'll check at work tomorrow morning and let you know.
If you don't have connectivity issues, it shouldn't go to band 12. As band 12 is a lower frequency and cannot carry as much bandwidth. From what I've researched previously, the phone will only take a band 12 signal if there are no other bands with a stable signal in the area as tmobile got it for the sole purpose of distance and wall penetration achieved at 700mhz to say they have a larger LTE coverage map.
. Also this from experience as my house only gets band 2 outside and when I come inside it switches to band 12. And with the lte booster connected, it uses the outside band 2.
Unless you are saying that your phone goes to no service instead of to band 12, then i have no answer
Dail *#0011# in your phone to see if band 12 is being aggregated with band 4.
If you want to see if band 12 works you could dial *#2263# and select only band 12 to work.

Thanks all. I bought the Verizon version cuz it's unlocked and it was the cheapest at Best buy. Plus it would be a hand me down for my bro who's on Verizon service when I upgrade lol I always thought band 12 was the godsend for Tmo. I did not know it was just a fall back band. I did notice today at work I was occasionally connected to band 12 but would almost immediately reconnect to 4 whenever I checked. Either signalcheck app was wrong or it really only uses 12 for a back up if nothing else is available.
