Disable LTE without custom ROM?

I have the ATT HOX and want to disable LTE due to the known issues with missed calls etc. Would it be possible to disable it through root access WITHOUT installing a custom ROM?

I'm not sure what AT&T do to their phones but can you not change it via Settings > Mobile Network > Network mode.

That's how it's done on my Rogers device.. should be the same on all.

Same on Telstra
Phone: HTC One XL
ROM: AOKP 4.2.1 MR1 preview w/ alloy blue theme
Launcher: Apex w/glaskart icons

Att one x doesn't have that function. Try to do it in service menu trying typing in *#*#4636#*#*
Go to phone info and scroll down. It works for me on clean Rom but not sure about stock rom

What known missed calls issue? What would LTE have to do with missed calls? LTE on AT&T is data only. It doesn't do anything with calls. You can dial *#*#4636#*#* and try to set it to gsm only or something.

Believe me I have tried. It's not possible. But ik you said you didn't want to, but you really should look into custom ROMs. There's some that are basically stock with just better battery

Except for ATT. Its a well documented fact that they have it disabled. Any changes you make revert back to default.

Its a fairly well known issue with ATT and LTE phones.
As far as I can tell since LTE IS data only it has a hard time receiving calls when its connected to the LTE network. I think it has something to do with only having 1 antenna and it cant communicate on voice and data at the same time. Or, maybe not.:silly: All I know is that when my phone is connected to LTE I will not receive phone calls. All calls will ring a few times and then go to voice mail. I eventually get voice message notifications when the phone switches out of LTE.
Any changes made in the field test mode do not stick. Thank you very much ATT.

I've had 3 different LTE phones on AT&T and never had issues with missed calls and I'm constantly on a LTE connection. My phone kicks to hspa+ right before I receive a call and then it rings. Goes back to LTE about 30 seconds after I hang up. The only thing I can think of is that you are on LTE only in the field test mode thing. That will definitely give you call problems. What does it say that you are connected to when you go into the phone information menu?

I've had a few LTE phones too but I can confirm that this is an issue with AT&T and the HOX. (At least in certain areas.) The phone is *supposed* to do what you said and switch off LTE when a call comes in but that doesn't always happen. I've noticed it the most at my office where I usually have 4 bars of "4G LTE" or one or two bars of "4G". I'll have a long period of time with no incoming calls or texts and then when I make a call (and the phone switches to "4G") I get the backlog of voicemails and text messages. Hard resets haven't helped and AT&T refuses to admit that it's a problem.

Heres a summary of what I have found:
1 Being in field test mode does not affect incoming calls.
2. When making outgoing phone calls with LTE or HSPA displayed in field test mode, the connection will switch to UMTS and then revert back to LTE or HSPA after hanging up. I dont know what that means, just throwing it out there.
3. On a few occasions during my testing I have noticed that I could not receive calls when HSPA is displayed in field test mode. I think that the phone had just switched from LTE, although I havent been able to 100% verify that.
4. My connection at my house varies between LTE, HSPA,EDGE.
5. EDGE is great. My phone makes and receives calls all day long when I have a EDGE connection.
6. Most of my testing has been at home where I have crappy reception to begin with. On a few occasions when I had my wife with me I had her call my phone(connected to LTE). Same as when at home, my pone never rings.

Exactly!

I have Samsung Galaxy S3 on AT&T and I have same issue when connected to LTE. I have been working with AT&T CSR for over a week and no resolution yet. I have talked them into switching my data plan from 300MB LTE to Unlimited Standard Phone data plan. (Unlimited standard phone data plan uses HSPA+ and not LTE, which would resolve the issue)
From what I have understood so far, its not the phone, its the AT&T LTE network.

Wouldnt people with the same phone have more answers for you?

No, because this issue is not related to the phone but its related to AT&T LTE network. So everyone on AT&T LTE network has same issue and not only people with HTC one X.

I was on phone with them last night. They have created a case number for me so their "technical team" can look into it. They promised me to get back to me before friday on this.
For changing the data plan, the CSR tried to change it but it didnt work yesterday. I blame it on the CSR because I know some people on XDA has done that before. I am gonna call them again and have a different CSR try it or me.
And plus, with this change, you get unlimited HSPA+ for just $10.

Thanks for the link. Those settings actually worked for me. I had already tried a couple different APN configs but none of them seemed to stick.
So, now I have successfully disabled LTE.
Unfortunately, I'm still having intermittent missed calls with the phone connected to HSPA. Also, At work in certain areas, we have rock solid LTE reception and guess what...no missed calls. WTFrack?
At home the only time I can get regular calls is when the phone is connected to EDGE.
I seriously think that there must some relationship between 4G/LTE and signal strength. Does anyone know If EDGE and 4G/LTE use the same towers or same power outputs?

LTE not working?! Manual Programming codez (updated)11-7

I got my Nexus 5 yesterday and finally got it working. I live right next to a LTE tower and I can't seem to get LTE.
1. Checked PRL
2 Checked Sim
3 Checked Profile
4. Called sprint
5. Checked network settings.
When i put the phone in airplane mode, and back off. It jumps to LTE for 2 seconds then 3g
Anyone having these issues ???

*manual re-fresh*
*#*#72786#*#*
after that, phone will reboot and "re-fresh network"
Also, my phone wen't into global mode, which you will need to change that back to LTE mode.
- Still isn't fixed ...
will report back ..

Manual Programming Code
*#*#675#*#*
edit: MDN = phone number
MSID: split

UPDATE
doing *#*#4636#*#* and selecting LTE only does indeed make LTE work both visually and functionally, with a loss of voice of course, but as soon as you go back to LTE/CDMA auto it'll require a reboot to take effect and LTE is once again not working.
(from sprint forums) - confirmed

I'm having these issues with Sprint as well. Thanks for your updates. I'll let you know if I learn anything.

You're Welcome,
Yes, this is very aggravating. My friends have LTE sprint phones and get LTE standing right next to me.
There is something wrong here! :/

On phone with sprint now, I hope they have an update.

Here is how I fixed it for myself on Sprint.
Settings > More > Mobile Networks > Network Mode
Change Network Mode from Global to LTE.
It will still connect to Evdo, ehrpd and Lte and switches between them as needed.
Luckily I haven't got hit with 1x since trying this out. My area has maybe one or two spots where I'd get 1x instead of ehrpd.
Settings hold after a reboot. I was driving to work today with my phone playing my music and it seemlessly switched between 3g and lte on it's own.

I guess so because I was having that same initial problem you were where LTE would connect for a few seconds then when I tried to do anything with data it stalled out and went to 3g.

Mine does that too.
BUT, nothing in the settings has been able to fix this.

How long since you activated? Mine would not connect to lte at all until last night... about 30 hours after activation.
Now it connects fine. I tried everything including flashing the modems posted in dev, swapping sims, trying every different network config and nothing worked except lte only mode which then kills 3g and voice.

I too am having the exact same problem as the OP. I can change the setting from Global to LTE and the phone will connect to LTE for a few seconds before switching back to 3g.
I am coming from the Note 3 on Sprint that got great LTE here at home, about 16mb down and 4mb up but I am hoping this gets resolved quick.

I'm on T-Mobile and it favors sticking on HSPA+ instead of LTE. If LTE gets down to one bar, the phone decides it's time to switch back. Compare this behavior to my Nexus 4 and it would stick on LTE come hell or high water. I would stay on LTE while in the office and this phone refuses to even get on LTE in the office. I don't get it.
Some have suggested this is a "power saving" feature, but I call BS on this because my Nexus 4 wasn't even intended to have its LTE radio used and LTE really didn't impact my battery. It felt like it lasted the same as it did before I enabled LTE on it.

Possible Sprint Fix
Customer: Is the SIM device specific? I reused the one from my Note 3. I have seen other information that the SIM's for the Nexus 5 are device specific.
Mitchell C.: Yes, you can get a SIM for the Nexus from a nearest Sprint store. I can fix an appointment for you.
Customer: so they are device specific?
Mitchell C.: Yes, they are.
Mitchell C.: We've come across a lot of these issues today.
Customer: SO just to be clear, I need to ask for a SIM for the Nexus 5?
Mitchell C.: Absolutely.
Customer: ok
Customer: that should correct my connectivity problem?
Mitchell C.: Yes, every service will work fine after you get it.

Well, I got my sim card from a sprint store 2 days ago and I am still having issues. I have been emailing sprint care but no luck.
I hope they fix this soon! Maybe they gave me the wrong SIM? Idk

Doubtful Mitchell knows what he is talking about. People have used HTC One SIMS and GS4 sims and have LTE. But, today is the big day the Sprint phones go on sale. Will be interesting to see if any of those people have the issue.

Still stuck on 3G after activating around 72 hours ago.
To follow up on the Nexus 5's "special" SIM card. I'm also skeptical about this. I'm using a SIM from a GS4 (part #: SIMGLW206R) which is the same SIM mentioned in this post about activating the Nexus 5 on Sprint: http://qbking77.com/google-nexus-5/activate-nexus-5-sprint/.
However, I called a nearby Sprint store to ask if they had any SIM cards available. They said yes but when I mentioned the Nexus 5 the representative seemed to think there was some additional procedure for coupling the phone and the SIM. I don't know any more about this. Could be misinformation of course.

No more LTE connection after upgrading to cm12.

As the title suggests, I no longer have connection to LTE services, beforehand I could get full signals.
I downgraded back to cm11s, and installed the previous XNPH44 modem, still no luck.
I have also tried XNPH33, 30 and 25. I have even tried the ColorOS modem as well as the M9.
Furthermore, I have tried the *#*# secret settings, currently it is on LTE/WCDMA. I can reach H+ connectivity but still not LTE.
I live in Australia, and am with Vodafone. Meaning Band 4 is the one I need to connect to, (1850mhz I think.)
Please advise on what I should try next.
Thanks.

Haha, you're not much help are you.
As written above I used to get full LTE coverage in my area. I even included the LTE band that the LTE broadcasts on.
It is also confirmed on Vodafone's website if you want to have a look.

Is your issue similar to this thread or do you simple just not have LTE, only and never get it on CM12?

Thank you!!! I have had my OnePlus One on cm 12s for about a week and the LTE has never worked since I upgraded. Just H+ works. And more than that - it keeps turning the H+ (3G) on and off which I think it's really killing my battery life!!! I have been trying loads of things to get my battery life back to what it used to, huhuhu. Turns out my APN got set to T-mobile somehow! I have Red Pocket mobile GSMT which runs on T-mobile and I always got LTE with it till the upgrade. (I'm in USA.) Just had to switch the APN from T-mobile back to Red Pocket 4G. The LTE works again and never cuts in and out!
:good: :good: Thank you! :good: :good:

[Q] F350S on AT&T in Ohio No 3g/LTE

I've been scouring the internet trying to find a solution. I've been wanting this for a while. I did my research to figure out which model of the G pro2 worked with AT&T. It arrives and now nothing. I'm only getting G not 3g or LTE. I am a bit new to smart phones. I've tried everything I can think of. Am I using the wrong apn settings? Is there something in the band selection menu I'm missing. I'm at a complete loss what am I doing wrong?

In Dialer 5754#*350# and activate your Bands or 5457#*350#

Still no dice
I've gone into the menu and specifically selected the required bands but still not dice. I went into the lte band selection menu. Is there another menu I should go into?

I have yet to root my phone I am a bit of a newb when it comes to things like this. I do plan on rooting it and giving it a Skin that has a lot more english. I have done this I selected bands 17 and 5 for lte and 850, 1900 for wcdma and gsm. In the Band Selection Menu. Should I be doing anything with WCDMA Channel, LTE Channel, WCDMA Security, RAT mode, RRC Version, SMS MO Domain, Service Domain, any specific APN setting what is it on your wife's phone, EF file edit, HSPDA category, HSUPA category, GCF Test, OEM RAD Settings, SKT Auto Test, IRS Setting, CA Setting, LTE 3GPP Rel. VER. or anything else I am missing?

I've determined that my phone is a very good fake
IDK if this is real issue but if some does have this problem and comes up with a solution. Please post it here I was beyond frustrated and hope this problem can be solved for someone.

Try going back to 4.4 and using LTE

Try taking your phone to an AT&T store and explain it to them. They will install a new SIM card and associate it with your IMEI #. Then you will have LTE!

I'm sitting in front of a Tmo store waiting for them to open and see where that goes. Hey guys how's battery life with this device. For what ever reason when I did put a Tmo sim in this phone it got only 3g now the chip was a nano from my nexus 6 using a quality adapter but holy crap I've never seen a phone eat a better like Godzilla. Hell it killed the device in like 3hrs. Although when removing the sim it seems to go normal using just WiFi connection. Very strange device behavior. Does this phone have bad battery life in its normal state? Since I am a huge "Big Screen" fanatic I would probably just get the extended battery from the Japan guys on amazon. Your thoughts?

You can also increase RRC Version, HSDPA Category, HSUPA Category and LTE 3GPP Rel. Ver. if your carrier supports you can get higher speeds.

No data during calls?

Hi Guys,
I'm using the US Mate 9 with AT&T, a GSM provider. I noticed when I'm on a call either there is no data (Internet) available or very patchy with the screen on...
Wanted to ask you guys if this is normal and expected behavior?
Thanks!

I dont think is normal, I've seen icon change from 4g to 3g to H+ when I'm on calls but still able to open facebook,whatsapp or firefox while calling. I'm with Tmo tho.

It's because At&t doesn't allow VoLTE on the Mate 9 so when you make a call you get dropped to 4g or 3g speeds. T-Mobile allows VoLTE so data doesn't change due to a call. I run both sims in mine and it's why I keep my personal line on T-Mobile and use it's data. My At&t line is strictly for work calls.

Thanks for your responses guys... In all my years of using all these different phones on AT&T, I've never ever noticed this since the Verizon days. I'll take the degraded 3G or H+, but yesterday it went straight to no data. Do you guys think I need an adjustment in my APN or is it a buried setting somewhere to fix it?
Thanks!

I didn't adjust anything with my At&t sim so I don't think you should need to either. Also this is a brand new sim and number so it was never in a different phone. I know on my Axon I had to put it in my iPhone first to get it working properly but not this phone. Are you in a good coverage area?

Are you sure about this device not doing VoLTE.

The device does VoLTE, At&t however isnt allowing it on the device. I can switch my data to my At&t sim and take a screen shot and back to T-Mobile and take one if need be.

I notice after the update today the "HD" icon next to the call timer is gone. That sucks.

Is the 4GLTE icon for Tmobile? I dont get to show the LTE letters but only 4G in mine, probably because is the Chinese version.

Both At&t and T-Mobile show 4gLTE icons but At&t's drops to 4g only while in a call, T-Mobiles stays 4gLTE which verifies VoLTE only works on T-Mobile.
I believe you're correct and the Chinese variant doesnt show LTE.

[SOLVED]
Guys, thanks for all your helpful responses! Just to close the loop on the issue of *NO DATA* during calls was fixed with the check box, checked in the attachment.
Although, as shared here, it's possible that it's H+ or 3G only service, not true LTE.
Thanks!

Alternative Solution
I had the same problem, I found out that this box was already checked on my phone, What fixed it for me was checking Mobile Network -> Access Point Names> selecting "ATT Phone"
I had initially selected "ATT Nextgenphone."
