[Q] LTE only setting?

Is there a way to force the phone to go LTE only no 3G? I dont see an option for it in the settings. I live in a 4G area and with my thunderbolt it ALWAYS was 4G but my M bounces back and forth, but if I put it in Airplane mode and then take it out it will connect to 4G.

go setting and add 4G to the notification bar, there you can choose the one you prefer.

You can do it without the app....open your dialer type*#*#info#*#*
A menu should come up choose phone options, there you will find the radio options. You can pick lte only.

Well both those get to the right spot, but there is no selection for what I am trying to accomplish. On LTE only it won't make calls or send texts. I assume bc LTE is only data. What I want to eliminate is 3G while having voice service forcing the phone to only connect to LTE for data. Is that even possible?

I think if you go to the phone testing menu(*#*#info#*#* in dialer)you should be able to select lte/CDMA only.

That would work if "LTE/CDMA" was an option. the options are LTE/CDMA/EvDo LTE/GSM/WCDMA LTE/CDMA/EvDo/GSM/WCDM LTE only and LTE/WCDMA,

Sorry I see that now. I was trying to help you off my memory. Should have done my own research. It seems that should be an option to choose. There has to be a way, we will have to find it

[Q] Sprint 4G LTE Connection Issues

I know for a fact that Sprint's LTE works in NYC because I've used it before. Since I've exchanged my S4 I haven't been able to connect to LTE at all. I've even checked ##3282# and it says LTE is enabled and I've gone to settings>more networks > mobile networks>network mode and have CDMA/LTE/EVDO checked off. What could possibly be the issue?

Have you tried updating your PRL and profile yet? Menu/settings/more/system updates
****'ll Buff Out

I'm in the NYC area and lte is spotty at beat. Hell, I usually get it in my house but sometimes it will drop for no reason, than it won't come back up for 5 to 10 minutes.
There are times when I'm riding the train and there is a 4G signal but there's no connection to the 4G network.
Does your show 4g on the screen at all?
Have you checked the Sprint forums for NYC?

Oddly enough I didn't think to do that. I'll sww if it works this weekend. Contacted sprint too and they refreshed the services on my account. They said if it doesn't work then let them know.

I did this and when i check my LTE shows as disabled. Is there anything i can do to turn this bad boy on? I used to get 4G at my job site with my Evo 3D and now i don't even get 4G with my Galaxy 4S. I called Sprint and they told me is not a good service area but i don't bite it cause i used to get full bars on 4g and now nothing.
Any ideas guys??

The Evo 3d used wimax not LTE. This phone is LTE not wimax. Do you even have LTE in your area yet. Most places don't. Go to settings, connections, more networks, mobile networks, network mode should say LTE. Make sure your prl and profile are up to date if you are in a LTE area.

[Q] Cannot get T-Mobile LTE enabled at all

info about my phone:
baseband: .33 right now
ROM: this one at the moment.
also tried this one, this one, and this one
also, its the new white nexus
what I've done so far:
I've tried this on the .33 baseband.
I then found these two zips (1 and 2) to help automate the process a bit, and use those to try baseband .24 and .27 with no change.
then I tried the instructions on this site
and finally, I am now on this rom I mentioned above, which is supposed to have everything done already...
I Know for a fact my area has LTE, as my roommate gets 4G on his S3 every day.
does anyone see anything I might be doing wrong?

Is your roommate using LTE with T-Mobile?
Nexus 4 only supports LTE band 4.

are you sure that your roommate has an lte enabled sgs3? the tmo lte enabled sgs3 only went on sale on june 5th.

removed

did you update the APN to fast.t-mobile.com? I can't tell in specific so ill just give you a quick run down.
On multiple devices i've done:
1) flash broadband
2) clear caches/factor reset
3) flash AOKP (or CM 10.1)/GAPPS and clear caches
4) flash franco kernel (not necessary but i prefer it) and clear caches.
5) update APNs
6) change to LTE/GSM in phone info settings.

I have done all of this. I have the T-Mobile lte APN with IPv4/IPv6. I have also tried just IPv4 or IPv6.
O have also tried creating a new APN with the correct settings
Edit: the settings in the *#*#INFO#*#* menu is LTE/GSM auto (PRL)

Can't get 4G to work.

I have flashed mine and my girls phone and 4G won't work on my phone. Hers works fine. I just reflashed to mdl took the ota mf9 update and then flashed sacs rom and kt kernel.
My phone is used and hers is a week old.

might have ruined something with the modem firmware.....might wanna flash stock and take it in.

Another difference is I don't have a sim in my phone. Would that matter? So I can't check mobile data in the navbar. Not sure why this occurred to me right now as we wait to eat.

You need a SIM in the device to get LTE. The SIM ID is how your phone identifies itself to the network to gain LTE coverage.

Got the last sim card at my local store. No issues with bringing the phone in rooted. When I got home the phone lost sim card access. Chatted with sprint and they had to add the SIM card number into their database. Everything works now.

4.4 and Non-VZW carriers

These issues apply to T-Mobile users installing the current build of 4.4 (and possibly other GSM carriers but I don't have an ATT SIM to test). Motorola is aware of the issue. I read these forums pretty thoroughly and I've been answering these questions all over so I figured I'd just put them all one place. Issues as follows:
- Devices with the LTE radio active cannot send SMS
- Devices with the LTE radio active cannot send MMS (Carrier/Settings dependent)
- Devices with the LTE radio active cannot make phone calls and instantly disconnects on call attempt.
Urban Legends:
- Stock tethering does not work - I have personally tested on TMO and know it does work. Yer doin' it wrong.
Fixes
Easiest fix for now if you're on a device running 4.4 and want to... you know... be able to use your phone... is to use phone information and switch the radio mode over to GSM Only (not the auto one). This fix is a little finicky because if the phone realizes it's not running in the mode selected on your mobile networks screen it will override and turn LTE back on if you haven't selected UMTS only.
Full steps are:
Mobile network settings - Change network mode to LTE/GSM/UMTS
Mobile network settings - Select network UMTS Only
Install app linked below
Open Phone Info and select GSM Only
Phone info apk for sideload - http://www.mediafire.com/download/284l17ry2ok1yuk/Phone_info_1.3.apk
I'll update this thread as I discover more issues or as people post issues that can be replicated below.

Thank you. Finally I got the LTE turn off.
I gotta switch the mobile mode to LTE/UMTS/ gsm and select network as UMTS only. Then use phone info choose gsm only.

It was selecting GSM Only in Phone Info. Switched it to GSM auto (PRL) and I got HSPA+ back.
but Seriously dude. thanks for this info. I was tired of using my Moto G while my MAXX was just collecting Dust.

Edited the OP for a more clear fix. Thank you to vuphongkkk for pointing out the UMTS only.

I'm on T-Mobile and live in an HSPA+ refarmed area (NYC), but there are places I go on a regular basis that aren't refarmed. I set it on "WCDMA preferred" and voila, I have both 2 & 3G connectivity, with preference given to 3G.
I can't post links, but this XDA thread explains it in more detail I think: ... showthread.php?t=688492

Vodafone confirmed for anyone wondering.
H+ for UMTS only,
Edge for global.
No Sim adjusting at all

Just popped a sim in today. Getting LTE but really hating the call fail bug. Gotta place the call twice repeatedly to get it through
Maxx'd out Kit Kat

Update: Having major glitches when running LTE, pretty deal breaking for a full switch to tmo right now. Eagerly awaiting the new OTA to see if it fixes it. Seems to have major issues on the HSPA/LTE handoff. How did it function prior to 4.4?
Maxx'd out Kit Kat

On 4.2.2 was working fine, the phone just switch from LTE to 3g itself when you need to make phone call. But I had problem on 4.2.2 that if I connect to WiFi then it'll take awhile to get the LTE back. Normally an hour after out of WiFi range

Maybe thats the problem I was having? I just ended up with a 4.2.2 phone after my 4.4 got destroyed. LTE wouldnt work for me but I was in the house after switching off wifi...hmmm

Arcanexvi what's the best APN to use for 4.2.2? And do I have to have phone info installed or can I uninstall it? Since I changed all the settings to get hspa+ I forgot what the default settings were. =\ whoops and thanks for all your help so far

You can uninstall it if you want. It's extremely small though so no reason to do so unless you just don't want to see the icon. Uninstalling will NOT reset your settings.

Thanks! I messed myself all up though.
In android mobile network settings should I have network mode as global, LTE/CDMA or LTE/gsm/umts?
If its LTE/gsm/umts do I still use gsm only under select network?
And if I leave phone info installed do I have to change anything on there for LTE to work? Phone info seems to change the network selection in the app on its own so I just stopped messing with it. Thanks and sorry to be a pain

I'm on 4.2.2 and already changed settings. So was curious on what the original settings on 4.2.2 are to get LTE working with APN settings
Sent from my XT1080 using xda app-developers app

4.2.2 rarely get LTE data. Choose network mode as LTE/gsm/UMTS . select network as automatic. Don't use the phone info. If you already use the phone info app in this thread then use it again to switch back to LTE/gsm.. Or the option that has evething.
Remember to add APN fast.t-mobile.com
But as I mentioned, 4.2.2 has some problem with the radio , so it rarely pick up LTE

Just to add another data point, I have a Droid Mini on stock 4.2.2. I'm connecting to t-mobile with the listed apn info, global and auto. I have LTE the vast majority of the time.
