Enable voLTE on Galaxy Note 4?

Hello,
I am currently with T-Mobile and own a Galaxy Note 4 SM-N910U model, the exynos variant. Is there a way to enable voLTE on this device through some menu? My carrier supports this feature and I know my phone does as well, but it is disabled because the data drops to 3g whenever I make a call.

Anyone?

On mine is in the menu

Hmmn.. Mine isn't in the call menu. It must be in some hidden menu.

Have you used the search function in settings?

Yes I have, but it is no where could be found. I am going to contact Samsung later.

Don't see it on my sm-n910c either.

I confirmed with Samsung that the device indeed has support for voLTE if your carrier supports it. They informed me that it should be turned on by default, which is a lie because my carrier has voLTE and whenever I make a call, the data drops to 3g.

In Japan......if we bring a self acquired device and use it on their network.......certain feature will not work.
Like VOLTE....as I just discovered. They have a separate APN for other devices and it does not support VOLTE.
The other APN that their carrier branded phones use....recognizes the phones based off of their IMEI number.
So.....it might not be a phone issue. Could be your carrier skimming on certain features for phones purchased elsewhere.

Don't see it on my sm-n910f either

hi all, i don't see the menu in my SM-N910F
In your opinion, Is it possible that VOLTE works only on Note4 Exynos? and doesn't works on Snapdragon based Note4 ?

thanks but i don't want to invalidate the guarantee.

Guys I also have a N910C Exynos Variant and its quite frustrating to know that a flagship device doesn't support VoLTE !

You won't find it in system settings

Just go to 'Phone' & then tap on 3 vertical dots and then select 'settings' and then select 'call' and after that enable VOLTE

can someone explain me what is the purpose of Volte? for what you use this?

volte is Voice Over LTE. It is basically what it says on the tin. You can make voice calls over LTE internet connections.

VoLTE (HD voice) and Wifi Calling WORKS with the SM-N910T.
I am currently using this device, with "MetroPCS by T-Mobile". As of 01-29-2021, T-Mobile will only allow the SM-N910T to work on their network. The "T" variant only, because it is T-Mobile's own device. VoLTE (HD voice) will work if you use OEM stock Android 6.0.1.
Here's how I enabled VoLTE (HD voice) and Wifi Calling:
Backed up ALL my files.
Removed SIM and SD cards.
Made sure battery had at least 80% !!
(If using a generic battery, it must be 100%. They drain faster!)
Used Odin (v3.13.1) to flash/install lastest Stock Android 6.0.1. (This wiped everything, even storage, pics, etc.) First boot took over 20 mins!
After reboot, connected to WIFI.
Went to phone's Settings, About Device, Software Updates, and tapped Download Updates Manually. This caused it to find a modem (baseband) update. I chose to install it NOW. It did just that, and rebooted.
Powered off phone.
Reinstalled SIM and SD cards.
Turned phone on, and VoLTE (HD voice) was fixed. Whenever I speak with another HD caller, "HD" appears next to their name.
To enable Wifi Calling, go to Settings, More Networks, Wi-Fi Calling, and enable it.
CAUTION / Extra Info:
A few days ago, I broke the screen on my primary SM-N910T. The screen would not light up, and it did not respond to any touches. I went to a MetroPCS store, to move my account to another SM-N910T. The sales rep said he could not move my account to the other device, showed me his computer screen as "proof", and said it needed to be HD voice compatible. I told him both phones are identical, and both had VoLTE working perfectly. Then he offered to try it anyway for $29 (non-refundable). I politely declined, went home, and swapped the motherboards. All is fine again. I shared this story in case you encounter similar resistance, and need to tell the sales rep you are willing to take a (non-refundable) chance. And to warn you that T-Mobile might have made some changes, that I am not aware of. However, I am currently using the SM-N910T.

flashed my g930vl to g930v cant activate adv. calling?

i flashed my straight talk version s7 (factory unlocked) from g930vl(stock) to g930v(verizon) using latest update of odin. everything works perfect except i cant activate advanced calling features. i know other have flashed and activated advanced calling. can anyone help me figure out how to activate or provide a firmware that has it activated? i used the nougat rom from samsung.

As far as I'm aware, verizon doesn't allow mvno carriers to use their advanced calling through ST or Tracfone

Yes it does. It also says searching for signal whenever I reset my phone. It has internet but I can't receive text or calls until I make an outgoing call then it switches from searching for service to Verizon service. I wonder if it had anything to do with ims registration? (Says it's off )

But using straight talk i was already on Verizon service (that's who they use in this area) of I flashed Verizon firmware I'm showing official device shouldn't I be able to activate the features? I swear I saw a post a month or two ago a guy flashed to Verizon from unlocked device and was able to do ota updates (which I can't i have to plug into laptop) and had activated Wi-Fi and video calling. I'm not sure if he rooted or not but I've been trying find post for about two weeks can't find it anymore. But any help or recommendations are appreciated. I haven't rooted but been thinking about it. If you could recommend a link would be greatly appreciated.

Straight Talk /Tracfone does not block the service provided by Verizon. My new Galaxy S8 G950U Settings/ Advanced Calling /Activate, is a Verizon app that controls access. Without vzw service you can't activate.
Has anyone found a fix to enable activation? Hoping root comes through on this.
Note: ST after 4 calls to customer service said there is nothing they can do.

Is there any setting to turn on mobile data usage during calls? Samsung Galaxy S8 G950U. This worked in S5 w/ST but S8 is not.

AT&T & Verizon VoLTE and VoWiFi calling/texting thread

Hi all. Posting this for users looking for answers on VoLTE and WoWifi on the 6T on AT&T & Verizon. If users with access to the OP6T could please test and report, that would be very helpful. Since the pixel 3 now supports both VoLTE & VoWiFi (on AT&T) there is perhaps some hope that OnePlus will also support it.
1: On AT&T, is there an option for Voice over LTE and Wifi calling and does it work?
2: On Verizon, I know Voice over LTE will work, but what about Wifi Calling?
Screen shots welcome I will have my hands on the device as soon as its available and will report since I have all the carriers, but thought maybe someone might get their hands on one early and could report. It might make a big difference on whether or now some users buy the device.! Thanks guys!

Yeah, whether or not I get the OP6T depends entirely on whether VoLTE and VoWiFi work on AT&T.
Eagerly waiting for updates!

AT&T & Verizon VoLTE and VoWiFi calling/texting thread
Same here. I’ve got a spot in SC where I got for holidays annually where, without Wi-Fi calling, my phone is a paperweight. I’ve always wanted to try a OnePlus but if there’s no Wi-Fi calling I’ll have to pass and stick with my XS Max.
I’ve already ordered but it’ll be a quick turnaround if that doesn’t work.

This question came up in the AMA with the OP team in their community forums last week, and Pei himself said VoWifi isn't supported at the moment.

Just got my device today so update time..
1: VoLTE works on Verizon by default as soon as you pop in the SIM. All the Verizon LTE bands seem to work fine.. in this area, 2,4,13, & 66. no option in the menu for wiFi calling, even though it works fine in my pixel 3 where my verizon SIM just was.
2: Neither VoLTE or VoWiFI work on AT&T by default. No option for either in the settings at all. So no change there from OP5/5T/6 ETC. However, if you go do the dialer, dial *#800# and hit enter, select oneplus logkit, scroll down to function switch and select it, and check the box for VoLTE switch and Vowifi switch and then reboot, it puts the VOLTE setting and VoWiFI setting in for both the Verizon and AT&T SIM. and while you can enable VoWIFI on both Verizon and AT&T, it DOES NOT work on either. On AT&T however, as long as you have a VOLTE capable/recognized IMEI on your AT&T account for your line, VoLTE/HD voice work just fine.
So, while it is amazing to have, for the first time ever a DUAL SIM phone that supports both VZW & AT&T at the same time, it is a too bad that VoWiFI does not work on either, Especially now that the Pixel 3 Supports it on both carriers.

Has anyone used the dialer code *#*#4636#*#* & try to toggle VoLTE &/OR VoWI-FI ?

Thanks for the info. I'm looking to get the 6T to use on AT&T. I've never used an unlocked/non-AT&T branded phone on my line. Are there any other limitations that AT&T implements on non-AT&T branded devices? Do they throttle data speeds? Any issues with SMS/MMS working like some Verizon users are experiencing? Would I need to contact AT&T to have any special provisioning just to get it to work? I appreciate any insight on this.

I'm not on AT&T so,I'm not gonna speculate.
Perhaps someone will chime-in soon for more definitive information.

My OnePlus 6t came in today. Took sim out of my Pixel 3 XL and popped it in. Everything is working except I can't SEND text messages. I can receive them and make calls, data is fine (actually amazing 44.5 mbps d/l, which is good for around here.)
I've tried chatting with Verizon, but after I told them what device, there was a long pause and then she asked if it was an iPhone
Here are my troubleshooting steps I've followed.
-deleted app cache and storage
-reset device
-factory reset device
-cleared cache partition in recovery
Any suggestions? I put the sim back in my Pixel and all the messages came through. I've tried both slots.
Mobile network state-Connected
Service state-In service
Mobile voice network type-4g
Mobile data network types-4g
EID-unknown (??)

There is another thread discussing why a lot of people using 6T on Verizon having problem receiving SMS and MMS. Something the phone being LTE only on Verizon. Maybe you are having the same problem? Worth reading that thread.

Yes. that would be best. I didn't need to do anything with mine, it just worked. However, I do have the latest version the the Verizon SIM card. Not sure if that matters. I was using a Pixel 3 before.

I have used AT&T for years on unlocked devices. I have tested everything Data speeds are just fine. no issues there. the OP6T supports all the bands on AT&T so coverage should be just fine for you. The limits are as follows:
1: built in visual voicemail will not work, you will need to use the AT&T visual Voicemail app from the store.
2: Wifi calling/texting will not work
3: VoLTE/HD Voice will only work with the above mentioned trickery. Root is NOT needed. just the *#800# thing
the only provisioning you may need is the AT&T imei for VoLTE (Easiest to do online) after installing your AT&T SIM in the OP6T, if VoLTE doesn't work after following the instruction in this thread, log into your AT&T account and update your IMEI to one of your past AT&T phones that support VoLTE and update, reboot you OP6T and bingo, it will work. No other provisioning or limitations that I know of. And if VoLTE/HD Voice isn't important to you, you can ignore all this. Your existing AT&T SIM just needs installed in your OP6T and your good to go!

The *#800# enables all those options. But it doesn't help anything on Verizon, and on AT&T it does work for VoLTE if a VOLTE enabled IMEI is on your AT&T account, but it doesn't work for wifi calling. I wish it was just illegal for the carriers to block services just because its a non branded phone

So glad that I found this post. I am coming from an AT&T branded Galaxy S8 to my new OnePlus 6T. The above instructions worked like a charm for AT&T. I ran some tests. The OnePlus displays "HD" when I call my wife on her phone on AT&T and VoLTE shows in the status bar. When I toggle it back off I lose "HD" on the phone call screen. Also, LTE stays on during calls with VoLTE turned on and I ran a speedtest with it on and off and I definitely get 4G speed with it on and it downgrades to HSPA+ with VoLTE off and speed goes way down. Hopefully VoWIFI will be supported soon but that's not a deal breaker for me as I get great reception most of the time where I live, work and travel.

I am on att had it all working on my unlocked NOTE 8. Now I can't even get volte cause it's all grayed out.

The service providers don't want you to buy unlocked phones. They make zero on them!! So that's why they block stuff. It's an antitrust lawsuit waiting to happen!! A$$h0!€$

I've got AT&T as my primary and Verizon as #2. I just got off the phone with Verizon, told them I needed to add the CDMA Less feature to fix my texting. He checked a box on his end and I got a flood of texts in...what was even better, it was a work phone on a business account. I didn't even have to provide any real information to him and he was able to fix me up. He was aware of the issue though, he'd asked if it was a 6T from T-Mobile...so someone sent out a bulletin somewhere that he had read.
Anyway, I left Verizon to go to AT&T specifically for this plan of having one phone to cover 2 lines while one being fully functional (AT&T), so far it's been working well switching between SIMs for texting and making phone calls.
What were you specifically looking to find out?
Edit: found what you're looking for...however I'm not sure where those settings are even at.

Yes it does, however, as of Android 9 (Pie), you will no longer see the Enhanced LTE Services tab under Mobile Connections as they are enabled by default. I confirmed this with Att. I am also able to enable WIFI Calling and can confirm it works.

Wifi calling not available

I have a S10+ that was bought from US Cellular that I am now using on Straight Talk with a TMobile sim. I had Wifi calling working just fine before I switched to the new Beta update. After switching back to Android 9 it now says "This is currently unavailable under the call settings for Wifi calling. I am at a loss. I live in an area were the cellular signal is spotty at best and need Wifi calling to work.
Anyone have any ideas?
Thanks

AT&T doesn't like unlocked phones so it's possible the option isn't showing up because of that. Many AT&T customers with unlocked phones have reported that they needed to contact AT&T customer service to get WiFi Calling or Volte working.
