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.

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?

Verizon Galaxy S6 jumps from 4G to 1X when making a call.

Got in a new Verizon Galaxy S6 and the second you make a call it goes from a strong 4G signal to a 1X with little to no signal at all.
Anyone else have this problem.
Is there a fix besides returning the phone?

Mine does that too. I imagine it is due to it not being possible to use data while on a non-VoLTE call. There are many threads about that aspect.

What's the fix?
Turn on HD calling and you loose your caller ID / Name / Number

I just went to settings, clicked advanced calling and hit activate then HD voice and video calling, wait a while then restart. Works just fine for me. Tested it before posting this just to be sure.

Mine was doing this but is has stopped. Enable Advanced Calling on the phone, then go to the Verizon website and make sure the feature is shown as active.
Reboot the phone. Wait 24-36 hours. Reboot again and the issue should be gone.
There seems to be a lag between when Advanced Calling is activated on the device and when Verizon actually begins using it. Not sure of the duration. It was about a full day for me. Since doing that, I have not had the warning message appear again.

Just be minded that in order for VoLTE to work, you need to be connected to a tower that supports it. If you're not, you'll drop off LTE since you're making the call over CDMA and new VZW phones have only 1 radio. Not possible for SVDO on any new Verizon phone now that they're moving to VoLTE.

Is the only benefit of Advanced Calling when you are talking to someone that also has Advanced calling activated on their phone?
Otherwise, what are the benefits of Advanced Calling?
Is there anyway to loose the video camera icon on the dial pad screen after you activate advanced calling? That thing would drive me nuts.

It lets you use data while on a call, since the call goes out over VoIP.

So does that mean all calls (coverage permitting) are being routed over VoLTE? even calls to non-Verizon HD capable phones?
Verizon implies that HD Advanced calling is only if both parties are using capable phones (VZW only) and are in VoLTE coverage area (and of course have enabled HD AC).
Is there any change to the way calls are handled for the majority of the time, when the above mentioned conditions aren't met?

I'm pretty sure what they mean is if you call someone else who isn't using advanced calling, the quality will be the same as they aren't on VoLTE, but you are. The quality is determined by the lowest quality of the two.

I'm not asking about the quality, I'm asking if regular calls to non VZW HDAC enabled phones are also placed over VoLTE and not over traditional CDMA

Verizon apps on unlocked model

Anyone else seeing a bunch of Verizon apps when browsing their app list via settings on the unlocked model? I'm on T-Mobile and yet have Verizon Login, vzw_api, VZW_multicast_mw, vzwapn, vzw oma trigger (cannot be disabled). What gives?

My guess is that Google put these in there since the Pixel was built to work with Verizon as the "exclusive" carrier. But it still doesn't make sense since Verizon dabbles with the software on their version anyway.

The ones that come pre-installed are for WiFi calling, VVM, and Video Calling.
Both models will install extra apps from the Play Store if setup with a VZW sim-card.

I've read that the answer is yes, WiFi calling should work for both Verizon and T-Mobile on the unlocked Pixels. I don't know how to tell if it's working on mine. I have an unlocked Pixel on Verizon. If someone knows how to tell, please let me know and I'll check.

Put it in airplane mode, then turn wifi back on and try to make a call.
On my Galaxy S7 I first had to enable wifi calling. Verizon does wifi calling differently from everyone else, it is part of advanced calling, and that is why I am dubious that it works on the unlocked version.

I enabled WiFi calling, put it in airplane mode, turned on WiFi, and attempted to make a call. The phone told me to come out of airplane mode. I checked the settings and saw that WiFi calling was set to prefer cellular network. I saw no way to change the preference to WiFi. Seems it will only do WiFi calling if there is no cellular coverage available.

Other carriers let you change the preference to WiFi, but not Verizon. I've had that message before and had to reboot and try again on my S7. If you are on a poor cell signal, the phone will switch to WiFi, and you will get a small WiFi icon on the call screen. If I answer a call in my house with the cell radio on, it takes about 3 seconds to switch over. During those 3 seconds the person I'm talking to is saying "hello," "hello." So, I try to leave my phone in airplane mode with WiFi on when at home.

This is all it takes for me. I don't know about receiving calls via WiFi yet though. I doubt that it made a difference, but I'll mention that I partially set up my Google Store purchased device over WiFi before turning it off and inserting my Verizon SIM. I didn't log into any accounts while on WiFi, only after putting in the SIM. It also updated from build NDE63L to NDE63P, and I have some VZW specific apps as mentioned, but they're not in the app drawer.

Would someone confirm 7Pro works on Verizon with working HD and WiFi ?

I am considering buying a 7Pro but i need to KNOW HD and WIFI calling work on the VZW network before I plunk down $$$

By default HD must be on to make and receive calls.
I don't know about WiFi calling. Never had a desire to use it or a need.

I do alot of work in a deep basement that has wifi but cannot get a signal from outdoors.

No VoWifi
I can confirm no vowifi. I'm on VZW. HD voice does work tho.

Yeah, VoLTE works but not VoWifi. Even when manually adding the option to turn VoWifi on, it doesn't work. I get crap service in my house but great service outside my house. I asked tech support about Wifi Calling and if it was provisioned on my account, but I was told if the phone can do it, the option will appear. I told them it can and it was working for another carrier. They said they don't know why it's not working. I didn't have time to stay and troubleshoot the issue though. Luckily the tech support person offered me an LTE Network Extender 2 for free. I have to wait until 10/16 for them to get more in stock though.

Verizon does not allow Wifi calling on devices it does not sell. So a Note 10 from Verizon has Wifi calling but an Unlocked Note 10 does not.

Wifi Calling in pixel 3xl

Hi,
I have pixel 3XL and i want to enable Wifi calling.
I have searched in my phone setting ( system settings>network and internet>mobile network), as well as in the phone app, and this option does not appear to me.
My carrier has this feature and i want to use this feature, but i don`t have this option.
I also looked in the secret menu(*#*#46...) of phone info and i see the VoLTE provisioned and wifi calling provisioned are on grey.
Can anyone help me how to enable this feature ?

There appears to be known issues with Pixel phones not able to use WiFi calling with AT&T out it's MVNOs.
For example red pocket AT&T service and cricket wireless both don't seem to allow WiFi calling unless you do some tricks like updating IMEI in their records.
Hope to hear from other members since I'm experiencing same issue.

I have spoken with the carrier.
They support only Samsung and Iphone, but he said he enabled this option for me, but he said he does not believe it will work.
Does anyone have an idea if there is an option to enable it via the phone with some kind of bypass ?
