VoLTE calls cannot connect? Help please. - T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting

If there's any info I would greatly appreciate it. While on LTE only mode I cannot receive or make calls
I have played with the settings and got it to work a few times flashed different roms, and reverted to stock but nothing I have tried works.
When I turn it to auto or lte/GSM I can receive calls but it auto answers?
And It struggles to get LTE back without me setting it back.
Any info would be great.
Debating on weather I should go back to the nexus.

When you say you reverted back to stock, do you mean you did an ODIN back to stock COD6? Have you tried this from different locations as in different cell towers.

First what firmware version are you on?
When you say LTE only mode, how are you getting LTE only mode?
So in Call you have "Use VoLTE when available" ticked off and then in More networks\Mobile networks\Network mode you have LTE/WCDMA/GSM ticked correct?

So if you ODIN to COD6 and don't put in that code and just use the settings I listed above does it work? Is that when you say it Auto Answers?
It has always worked perfectly for me using those settings and not trying to force it with any codes.
Just to make sure you know, it is working if you make a phone call and you continue to see the 4G LTE icon in the status bar. Not being able to make or receive calls may be related to you trying the code instead of letting it work like it does out of the box.

Can you turn LTE off with *#*#4636*#*# menu?

Can someone test to see if this works on the AT&T Note 3? You dial *#*#4636*#*# and then you can change the network mode. I am just curious if it sticks. For example, if you tap on WCDMA/GSM auto, you'll only get 2G/H+.
Would appreciate it if someone can test this out. Thanks

I don't think that dialer menu is available in touchwiz. You should have the option of changing your preferred network type from the settings menu though

It is. It's not available on non tw roms. AT&T takes out the network mode option in the settings.

I think that's backwards. I've always had that accessibility on my nexus devices but I've never seen it mentioned for a TW ROM.

Yea the menu is there here's a pic of the options for the AT&T note 3. I use it frequently while at work and set mine to lte only so I'm not bugged with phone calls but still have internet and text. It stays active until you turn off data, turn on airplane mode, reset the phone, or switch it back via that menu. There is also a wcdma preferred option at the top that wouldn't fit in the picture. Enjoy

Unable to get LTE after Un-rooting
Sorry if this does not appear to belong here, but since I have un-rooted my AT&T Galaxy Note 3 (N900A) using the Root de la Vega One-Click with N900AUCUBMI9 I have note been able to get LTE back. My device defaults to HSPA/HSPA+. After using #*#*4636#*#* in Testing Menu -> Device Information, I cannot even change the preferred network type to anything that contains LTE in it - only GSM or WCDMA preferred is accepted.
I would appreciate any help whatsoever.
Thank you in advance

Try booting the phone without your SIM. Might let you do it. If not your going to have to redo Odin back to stock again.

Sprint Nexus 6 Data Issues

I'm on a Sprint Nexus 6 running 5.1.1 (Euphoria) and have issues with my phone connecting to LTE. I will often leave the house or work where I am on WiFi and then it will connect to 3G where I should have LTE. If I put it in airplane mode and then back it will connect to LTE like it should. Sometimes it will even require a reboot.
I've tried different Roms and even returning to stock and still have the same issue. How do I fix this?
Thanks!

Are you set to Global or LTE (recommended) in cellular networks settings? Also, in developer options, you can set to aggressively hand off to data from WiFi.

Was on Global, will try LTE (Recommended). Also just FYI, it will even occur if I'm out driving around and not connected to WiFi at all. It will switch to 3G and won't switch back until I toggle aiplane mode again or reboot.

It may be hard to believe but it may also be a sprint issue. Try the dialer code if you're on a stock ROM. *#*#72786#*#* select reset.

Unfortunately still having the same issue with Global and aggressive data handover on. And I'm on AOSP so the dialer code and carrier settings under mobile networks will not work. Any other ideas? Thanks!

Honestly, I'd flash a stock backup or a stock ROM. Then go into carrier settings and update PRL and Device config. Then flash AOSP again and see if it's any better.
I've tried AOSP a dozen times while on Sprint with different devices; not once have I been able to get data/mobile to work.. Just gotta stick to stock ROMS.

Have you tried using the data fix zip in the OP? I've flashed a bunch of stuff and only once couldn't get data going. ???

This seemed to have helped so far. Must have reset whenever I flashed a different radio while on AOSP. Thanks!

When you dial *#0011# what does it show you connected as?
Attached a screens hot hopefully it works
I am pretty sure I read that VoLTE and WiFi calling both do not work after flashing the custom kernels. I am not sure if they all break VoLTE but start doing some checking on the kernels and see if you find one that works better for you.
Flash Arter97. Wifi calling and Volte works. You will also need to install xposed. That fixed the issue for a lot of people.

Tried other roms and kernels and still nothing. My girlfriend is sitting next to me and she gets full 4g lte on her tmobile note5 (which is what mine is) yet my signal jumps from full to 2 bars and I'm still only getting 4g. Checked my apn settings used Odin and went back to stock completely and even tried the new baseband.....still nothing.

Pure Nexus 6.0 R1- Signal Works But No Data

[Q] on pure nexus 6.0 r1 I cannot get any data/lte my signal works but no data.?
I flashed the pure nexus ROM 6.0 release coming from benzorom some nightl y build not positive which. I flash the 6.0 bootloader and radio from recovery and then flashed the ROM and gapps. Can't get any data for some reason. Can someone help?
Are you on tmobile?? I had to add the correct APN to get data
Sent from my Nexus 6 using XDA Free mobile app
No I'm on Verizon actually. I always thought Verizon automatically had the APN settings stored? Its kinda odd. But it sucks because I want to use that ROM. Its so nice!
Here's your solution!

Hi all,
I installed the 5.1OTA and could not get Verizon Enhanced LTE (advanced calling, VoLTE, etc....) to work. I tried what everyone else suggested and nothing made it work (never showed the enhanced LTE setting in the cellular menu). Here are the steps I took in case anyone else is having the same problem.
1. Re-Install radio and bootloader from here: https://www.androidfilehost.com/?fid=95916177934540313
2. Enter the hidden menu using *#*#4636#*#*
3. Go in to Phone information
4. Click the TURN ON VOLTE PROVISIONED FLAG button (wont change)
5. Click the TURN OFF RADIO button
6. Wait a few seconds (for radio to turn off) and then click the TURN ON RADIO button.
7. Observe that the TURN ON VOLTE PROVISIONED FLAG button has changed to TURN OFF....
8. Go in to Settings>>...More>>Cellular Networks and make sure that Enhanced 4G LTE Mode is enabled.
I did all this and I still did not have data while making a call. I had to go to VZW site and go into my account and tell it to activate a device on my current line. I entered the IMEI and it gave me a warning about softcard and then went right back to same screen, When I clicked next it gave me a warning that it was unsupoorted device. After this it all worked perfect although the phone is still not recognized on the VZW site.

This and a quick call to Customer Care (*226) for them to provision Advanced Calling took care of it for me.

Go look at your apn settings/more/cellular networks/access point names/ find the one selected then compare it to what Verizon apn should be. I have tmobile and when i installed the ROM there was only two apns neither worked.

OnePlus 7 Pro International Version & TMobile

Has anyone had any problems with using the International Version with TMobile? Did you have any issues? Wifi Calling and whatnot?

I only just made the switch today and I've been using it like the last 5-6 hours, so I can't really attest to signal strength away from home. That being said, my data speeds on LTE are consistent with what I had on the T-Mobile firmware (here at home), and WiFi calling may actually be working better now (not joking here, but again, very early here). VOLTE is working as it should as well. Call waiting is broken on T-Mobile, no matter what firmware you have... So this issue persists and it's known on the OnePlus Community forums.
I should also mention there is no quick setting to turn WiFi calling off (nor anything in the regular settings menu). Seems the only way to turn WiFi calling off would be to turn off WiFi, or use the log kit app (dialer code) to get into engineering settings.
Everything seems really good for me so far. I'll update in a day or so. When I go to work, my LTE download speeds break 100mbps... Let's see if that continues with the international firmware.

May I ask, where in the settings is that? I've done what I thought was a very thorough search, in the settings app and within the dialer app. Maybe I'm an idiot.
Edit: I finally found the WiFi calling settings in the dialer app. Still no quick setting tile for me however.

So I assume the qs tile isnt there after updating to international?

I'm about to switch back to the international version as soon as I make a backup and copy it to my laptop. I don't remember if there was a quick setting tike for it or not. I don't use wifi calling so I didn't pay a lot of attention to see if there was a quick setting tile.

The international firmware does have *working* WiFi calling w/ T-Mobile, though the setting is kinda of hidden within the dialer app's settings menu (3 for button up at the top right, see screenshots). This is also where the VOLTE setting is found. Took me a while to find because there's like two different "SIM" settings menu, and I thought they were the same thing.
There is, however, NO quick settings tile. Perhaps an app like System UI Tuner or something similar could resolve that though.
