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

I believe op wanted to see what bands his phone/provider is using. LTE discovery shows what bands you are connected to.

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.

Hey All,
I searched the web on and on and cant figure it out.
My provider Vodafone in holland provides me with 4G.
On some sites i read there is a minor update which activates the LTE option.
that update is for the I9505..
I cant find if its possible to unlock my LTE option.
i have the I9295. And throug kies or OTA is no update
I hope you can help me out guys.

I can't really help you but as far as I know LTE is already unlocked and working on all international S4 Actives. Mine certainly worked perfectly out of the box - although I turned it off promptly because I have ****ty 4G coverage where I live so it was nothing but a battery drain for me.
Are you sure you have a 4G sim card, and that you are in an area where 4G has coverage?
If you go in under settings > connections > more networks > mobile networks > network mode don't you have the LTE option at the top?

Im not 100% but i got the textmessage from my provider, so i recon they only send it to people who are able to use the 4G.
Yes, i am in a 4g coverage area
i dont have the LTE option at the top no. i have:

Well then I really have no idea - the only thing I can think of is that you might need to replace your sim card if your provider didn't already do so in advance of the 4G rollout. Hopefully someone with more information might step in here, but the international version is LTE capable out of the box. If you don't hear anything else I'd suggest to try and contact vodafone and get a clear answer from them first.
If you check the mobile networks in your area and don't see anything that supports LTE, you may just live in an area that doesn't have it yet (people get 4G and LTE somewhat mixed up - 4G is the overall identifier for a whole class of technologies with "4th generation cellular networks" basically while LTE is technically one of those technologies so, it should rightfully be classified as 4G in most respects.
Having said that, the only way I got my GS4A to function in LTE mode - meaning it actually shows LTE in the notification bar under the 4 with a small G and LTE underneath it - was to go into the service menu (*#*#4636#*#*) and change the preferred network type to either LTE only or LTE/GSM auto (PRL). Once I did that the radio would reset and connect and then it would be in proper LTE mode. Doing a speedtest with the Speedtest.net app shows LTE as the connection whereas with my standard setting which is WCDMA Preferred (T-Mobile AWS) it'll just show as "4G."
I've had no luck making alterations in the Settings/Mobile Networks section, I have to change it in the service menu to get LTE functional. I don't use it because here in Vegas where I live (specifically my home location) the LTE mode gets me about 1-2 bars of signal (about 8-12Mbps) whereas the WCDMA Preferred setting pulls in 5 bars rock solid and 25-35Mbps.
Can't do screenshots or I'd add them, I'm running the pre-release MI2 ROM presently and that aspect is borked.

That would be because you're on the i537 from ATT, rather than the i9295 that this discussion is about. I checked google and vodafone holland does indeed use LTE on the right bands in its brand new rollout, so it isn't that - most likely it's his sim that needs replacing or it's just not activated on his account yet.
Hey,
Has anyone figured out how to set the band priorities on the phone, ##DATA# used to take you to LTE settings where you can choose the enable the LTE bands and set the scanning priority.
Also has anyone figured out how to shut off Band 25 but still use the other LTE bands?
Thanks
I wouldn't mind setting mine. I notice band 26 lit up yesterday it must have been from a further away tower. My phone wouldn't hold an LTE signal kept jumping on & off. Band 25 didn't have this issue with. My home tower they have been working on since last July but until everything is working correctly (it seems like it will be never) would be nice to have control of this.
I have looked in all the EPST screens I could think of and can't find it. I was actually hoping for the opposite, to disable 800 and 2600 since they don't exist here yet.

Yes that is weird, because they existed in both the LG G2, Samsung S5, S4, Note 3, Nexus 5, maybe it is hidden somewhere else.
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!

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?

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.

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
Is there anyway to force LTE band change between bands 13 and 4? At home, I have one bar on band 4, but get 60 dl, and 30 up. However, on band 13 I'll get full bars and get 30 dl, 15 up. I don't use my data at home as I am always on wifi, so this cell standby battery drain is murder. If I reset my data connection it will connect to band 13 initially, but it will then change to band 4. Switching my carrier is not an option as T-Mobile, Sprint, and AT&T get equally crap reception and I'm still under contract with Verizon which ends in October. Maybe then I might think about switching to project fi.
I've seen other threads on disabling certain bands, but those bands are only used by T-Mobile and Sprint, so they are of no use to me. Any ideas?

Maybe you can find an older radio that doesn't have the bands you don't want.

I have the same because here in the Netherlands we have the so called 4G. But when I am home (inside) there is bad connection. Phone calls are disconnected frequently.
With 2G very good reception at home.
On the road I switch to 4G when I need internet.
I use an app to quickly switch 2G-4G.
It's a rather old app of CurveFish and is in the play store - 2G 3G -
I have exact same problem but problem of speed.
There are 3 lte bands 850mhz,1800mhz and 2300 mhz.
2300 mhz has highest speed which i want my redmi note 3 to run on only but in my home it only switches between 850 mhz and 1800 mhz.
Searched a lot but not able to find any guide which allows to lock the frequency to 2300 mhz band only. The signal bar is also 3-4 on 2300 mhz still it connects to 850 and 1800 mhz most of the time unless i am in open area outside house then it switches to 2300mhz band.
Use QXDM

I've seen other threads on disabling certain bands, but those bands are only used by T-Mobile and Sprint, so they are of no use to me. Any ideas?

Hi - not sure if this is still a topic of interest, but you can use QXDM software to achieve this - you just need to change NV line 6828 to be "4096" decimal value. On the Nexus 6, this is a fairly easy process as you just need to boot to bootloader and select "BP Tools" as your boot-up option and then the phone will be in diagnostic mode to connect to a PC. There's info out there on XDA with more detail, but as long as you can successfully install the Motorola/Qualcomm drivers you can fairly easily restrict LTE bands to whatever combination you'd like.
Be aware - some say this is a risky operation but I've not found that to be the case. But there is a chance of messing up your device if you're not careful.
Take a look at the "NV Calculator" app in the Play Store for additional info on determining decimal values for the LTE bands (you might want to keep band 2, for instance, as Verizon uses that sometimes as well).
Here's more info on this on XDA:

Good luck!
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.

You have to select "Apply band configuration" after you selected the ones you want or they wont take effect.

got cha. gotta hit back to previous screen where i previous selected lte band, but press option 7 to apply setting. lol. still new at this but it works. although band 12 is just as slow as band 4 at home. i get faster speed with band 2, however, lte discover still shows band 4 even though im actually on band 2.
tks again

No prob!
I used LTE discovery before and it always told me i was on band 4 when it wasn't in my area, only 2/12.

never got to try the service modes since i been using verizon brand phones on tmobile , lol. it makes so much sense to use tmobile brand samsung phone on tmobile network.
anyway now i can wait patiently on the root. no need to get network signal guru now to change lte bands since that app requires root
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.
