I'm trying to figure out why VoLTE (Voice over LTE) doesn't appear to be working on the Nexus 5X on my carrier (Rogers Wireless in Canada). When I make a call, it drops down to HSPA+. While this still works for voice and data at the same time, it's less than ideal. I know Rogers supports VoLTE since the end of March of this year.
From the hidden *#*#4636#*#* menu, the option "TURN OFF VOLTE PROVISIONED FLAG" appears, but unlike the other options cannot be toggled. Additionally, the "Enhanced 4G LTE Mode" toggle does not appear under Wireless & Networks → More... → Cellular networks. I've attached screenshots of both screens.
Is this something that we will have to wait for a future update to enable? Currently on build MDB08I.

also curious to know about this... Do we know what band is used for VoLTE? I believe T-Mobile uses band 12 - (700MHz? or is 700 band 17?). Rogers rolled out that band a while ago (before VoLTE) presumably as a precursor for it.. maybe the secret lies here?
I cant test at the moment but I will when I get home.. Unless a zip can be made.
edit: 700mhz bands 12(700a),13(700c),17(700b) and 29(700d and 700e).

Band 12 is 700MHz (sometimes refereed to as 700 a, 699–716 UL 729–746 DL), this is used by T-Mobile. Rogers also has a 700MHz band, but it's Band 17 (sometimes referred to as 700 b c, 704–716 UL 734–746 DL). As I understand it, VoLTE is a prerequisite for enabling Band 12 on T-Mobile (along with E911 certification), but VoLTE should work for every LTE band (including Band 4, which is the dominant band used by Rogers/Telus/Bell).
I'm a little hesitant to flash the old radio, so please report back once you get a chance to try it!
I'm pretty sure Rogers on supports VoLTE on the latest apple products. Rogers sucks

From what I've researched, it supports VoLTE on the iPhone 6S/6S+, along with:
Rogers said:
The LG Vigor; the Samsung GS6, GS6 edge, GS6 edge+ and Note 5; and the LG G4 are all currently compatible. To see if your device is VoLTE-compatible, check the device specifications on rogers.com.

If you go to the device specifications on Rogers' website, nothing is written about VoLTE on any of the phones including the G4. However, on the blurb about the G4 when you search Android devices, it lists "Rogers VoLTE" as one of the features. Nothing on the GS6/edge/+/Note5 indicates they are compatible with VoLTE. LG Vigor is no longer offered.

so basically band 12 700a is useless to us on Rogers?

Right, since Rogers doesn't use it, it shouldn't matter to us.
I'm still not sure why the option doesn't exist (even grayed out) under "Cellular network settings" and why "TURN OFF VOLTE PROVISIONED FLAG" cannot be toggled. The option that exists for the Nexus 6 after the update to enable VoLTE was pushed (5.1) under "Cellular network settings" says "Enhanced 4G LTE Mode" as pictured in the attached screenshot.
It would be helpful if people who were on other networks besides Rogers (especially US providers) if they could post a screenshot of their "Cellular network settings" and tell us if "Enhanced 4G LTE Mode" is available. If people on other carriers have the option, then perhaps it is an issue of the device not recognizing that VoLTE is offered by Rogers?

According to other posts, the "TURN OFF VOLTE PROVISIONED FLAG" doesn't toggle but a reboot (or several) enables the Advanced 4G option to be enabled. I think both Verizon and T-Mo users have this option, just greyed out.
I don't get it either... we are all on the same firmware, I personally came from a G4 so VoLTE is active on my account but I think its a case of Rogers not allowing our "non supported" devices to use VoLTE. I'm calling tech support to see if they can help out..
edit: no luck.. they still have my device listed as a G4 and say everything is good on their end.
no amounts of reboots will help rogers.. but thank you..

Yeah downgrading the radio did nothing for us. Since 700a is useless to us I'm flashing the new radio.

Thanks for the update. I'm still curious to find out if anyone has the "Enhanced 4G LTE Mode" option in their settings, and whether it's a matter of the carrier settings or not being enabled in the ROM. The fact that Verizon people are getting HD calls indicates it has to do with our carrier. I'm trying to get in touch with Rogers and see if they could possibly enable it, they're selling the 6P in their stores so maybe there's hope for our lovely device.

I didn't realise they were getting the 6p.. This might help us out a lot. Do you happen to know an eta?
Edit: just saw that Canadian carriers will be getting the 5X "soon". The word is end of October. Also noticed on rogers' page that there is no mention of VoLTE being a "feature" of the 6P. Here's to staying positive that it and the upcoming Rogers 5X will carry this "feature".. :fingers-crossed:

Last news that came out said they would start fulfilling preorders November 4th. It was delayed a couple times so it could be delayed again.
So the device is available now on rogers, but it is not included in the list when searching by VoLTE. Moto Nexus 6 is tho...
Weird thing is my account was set up with the G4, so VoLTE was set up on my account and according to rogers it still is but I am not able to get it to work with my 5x.

Yeah, even with 6.0.1 it still drops to 3G for calls, I'm not exactly stock so it could be an issue with how I flashed it but I doubt that is the case. It is still the case that "TURN OFF VOLTE PROVISIONED FLAG" cannot be toggled in the hidden dialer menu. Also there is still nothing under "Cellular network settings" that says "Enhanced 4G LTE Mode" like on the Nexus 6.
Since Rogers is only offering the 6P, I don't know if we'll ever see VoLTE for the 5X... but if they patch it in for the software for the 6P, they could theoretically add it in for the 5X too. So maybe there's still hope for a future update that will enable this. 6P still is not listed as a VoLTE device on the Rogers website, but now they are allowing you to search for devices that support VoLTE, which shows you all the usual suspects. So perhaps this feature is getting more prominent for Rogers.
Bell and Telus are offering the 5X directly, but neither carrier has launched VoLTE.
I have the same questions/issues with AT&T as well. My 5X will not expose the "Enhanced 4G LTE Mode" either. I have all the IMS based features turned on in the dialer menu. Of course you will need a SIM that is attached to a VoLTE account on the back end systems, and I have several of them. You have to be provisoned in the HSS and TAS as IMS capable. If I look at a registration event from the 5X it says its voice service is "CS Only" while my other VoLTE phones attach as both "LTE Voice" and "CS Voice".
I highly suspect the 5X is coded to not allow IMS/VoLTE for other than T-Mob and VZ, but why I don't know.
Hello, I have a OnePlus 3 and have Sprint. Not realizing the device only supports GSM out of the box i found this thread: http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
Here one person was able to enable band 20 on a OnePlus One. I was wondering if it is at all possible to enable bands 10 or 1 for Sprint 3G. Or better yet bands 25, 26, 41.
I was also wondering, if I were to attempt this is there a risk of ruining the phone?
I recall band 20 was unable to be activated on the OPO as the device simply was not provisioned with a radio for that band.
Modding will not overcome hardware deficiencies.
Is Sprint a CDMA carrier? OnePlus do not support CDMA at all as the US is the only significant country using that outdated technology.

I do not think so.
First, I am assuming you have the international OPO. Go to willmyphonework.net and see for yourself; your phone is totally incompatible with Sprint. Even 2G bands are not available under its standard configuration.
At this stage you have two choices, return the phone for exchange/sell it or try and edit the hardware settings to make more bands available.
If you bought it new I would just return it rather than modifying the hardware setup.
If you want to tinker with it, you need to start here and also here and see will they unlock the bands you need.
Basically, follow the guides exactly and tick every radio band that appears in the programme and hopefully the bands for Sprint is among those available for your hardware.
I think I tried to activate band 20 4G and it did not seem to work. I have the international OPO.
The OP in the first link is a Chinese model, but the steps are the same.
To quote from the 2nd link I posted:
It will theoretically unlock:
GSM: DCS-1800/P-GSM/E-GSM/GSM-850/Railways-900/PCS-1900
WCDMA: Band I to XI
LTE: Band 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 19, 20, 21
PS: Even if they're theoretically enabled, some band cannot be used because of hardware limitation...

Even though all the above seem to be available to activate, some work, and some do not. [band 20 has a strikethrough, for example]

I believe you need the right. Qcn from the model phone with the supported bands you want for this guide. With respect to the oneplus 3.
Just curious because in all my excitement I failed to realize that the Oneplus 3 does not support Verizons band 13 I have the North American version BTW
i join in!
bought the phone while on vacation in the US. where i live, LTE mainly uses band 3 (1800) which is not supported by the US version.
only thought about it after i was home

Both the North American variant and the China variant share model number A3000, there's a high chance those two variants are the same piece of hardware. The China model is said to support LTE band 3.
You could try this out to enable all hardware supported bands. Please let us know the result.

Enabling bands on the OnePlus line of devices requires a patch to the NVRAM, one of which hasn't been made for the OP3 (and older patches cause bootloops). When enabling bands, the NVRAM resets on boot, reverting all changes. I've done some research and testing, and it seems that missing bands aren't the problem. It's provisioning. The OP3 fully supports most of the bands Verizon uses, but doesn't know how to switch between LTE and CDMA. You can force LTE with a few build.prop edits and changing some cellular settings, and it works blazingly fast - but, you can ONLY use LTE and nothing else. I'm still doing some more work, but a few people that know more about RIL than me have said they will begin looking for a solution around October. For now, just enable data roaming (which isn't actually roaming if you're in the US) and use 3G. I'm confident that we can get it working eventually.
Band 13 isn't some magical necessary band, it's just the first and therefore most common band. Yet my area doesn't even use it.

thanks for the reply.
i am actually currently living in Israel (so Verizon are quite far away )
the local networks all have LTE on band 3 (1800) which is not supported on my OP3.
i did manage to get 3g without doing anything, and following your bootloop comment, i will probably wait until October for someone with the know-how to generate a stable working solution.
thanks anyway!
BTW, while i was in the US (Oregon) i used T-Mobile and got LTE all day long with default settings on the same OP3 device.

Well, mine is China version and I mainly live in the US now. It would be a great deal if we exchanged our phones.
Anyway, I feel HSPA+ is fast enough for me, at least better than my wifi at home.

That I had no idea, Thanks for the information.
In fact the only band I need(more like Wind Mobile Canada need) is UMTS band 4, Wind does not have a LTE network yet.
I'm just trying to figure out if the China model supports UMTS band 4. If it does I could simply buy one here in China and bring it to Canada instead of spending 100 CAD more for the Canadian North American model.
Oops. Not used to having an international phone, forgot that not everybody is on Verizon . Anyways. Until someone can make an NVRAM patch, the only thing that might help are some build.prop edits. I'm actually currently searching for them, I'll post them when I find them.
So volte works fine for me but on LTE Discovery I only see my OnePlus 3 connecting to Band 4 and getting mediocre reception, and I'm pretty confident where I live there is band 12 (central Austin, Texas)
Anyone having a similar issue?

will editing the build.prop open up the locked LTE bands? or will it just allow me to force LTE on the currently available LTE bands for my device region?
more specifically, will this enable LTE band 3 even though the OP3 is the US version?
if so, i am willing to play along and if i get good LTE coverage at home and work, i don't mind it being LTE only.
I'm join too to the questions, like to take a part of this too, there is any news? Thanks
Also interested.. have only band 3 coverage and bought the OP3 in the US..
Thanks
As I see it now, I talk with few people and they all said that it can't be done
Yeah interested in knowing this as well since I can only really get the US version easily to New Zealand.
My provider only supports:
LTE (band 3) 1800 MHz
LTE (band 28) 700 MHz

It won't enable bands. Can't. It WILL force a connection to LTE on any supported bands in your area, though. I'm so sorry, but I'm currently in the process of finding the build.prop edits I mentioned, I had them on a thread on a different account that appears to have been deleted. The second I find them I'll post them.

So I'm having a hard time getting edits to actually work. I was on CM13 at the time and I'm currently on RR, but it might just be my location (on vacation). But for those who wanna try, here are the edits:
lteOnCdmaDevice=1
to.telephony.default_network=11
There were a few more concerning GSM and CDMA operator numbers, but those seem to have no effect. You might also have to fiddle around in the cellular data settings and change from Global to LTE.
One thing is for sure - these won't work on Oxygen OS. I can't get a lock on 4G on Oxygen no matter how hard I try.

thanks for your effort!
but that doesn't solve the issue, as the problem is not with connecting to LTE network but the LTE network being on an unsupported band.
forcing LTE will only leave my phone with no signal at all...
is there any way, instead of enabling locked bands, to change the region of the phone?
meaning, i don't mind losing the US bands if i can gain the EU bands.
so is there a way to completely change a OP3 from US version to EU version? so that no band unlocking needs to take place?
Joining the request. I have the same problem: missing band 3 on the US version.
Joining the request as well. I have de A3000 Chinese version and I need to enable Band 4 for Latin America
Joining the request, too. my country is covered by bands 3.
A3000
Yeah well I'm joining in.
Whoever makes a working NV/rmt/whatever patch for 64bit devices get a cookie from me. Or at least, find another way to prevent the device from resetting the NV edits we make. I got the North American OnePlus 3 and it's the one that doesn't support Band 3 (1800MHz) which my country's 4G connection runs at.
Rebooting resets whatever NV edits we make and even on CM it does that as well. I wouldn't mind staying on HSPAP but in a couple of years that might be just obsolete.
To any developer that's interested in doing this, I'm your guinea pig, just PM me and I can test anything for you.
I wanna buy this awesome phone from eBay and use it in my home country - Czech Republic, but there are still two things I don't know, so I'm holding off.
Can anyone, who owns the USA T-Mobile (1789-04) version, check for me, if it supports LTE band 20 (800 DD)? I scour the internet for the answer and some sites says it does, but some it doesn't.
And a lil' bit stupid question: Is there a chance, it will work locked, if I will use it with Czech Republic T-Mobile sim card?
Thank you all in advance for any answer.
as far as i can tell the T-MO variant does in fact support band 20, and the spec sheet from t-mo says the same.
https://support.t-mobile.com/docs/DOC-36016
That's what I thought too, but their normal website (where you can order Moto Z2 Force online) says otherwise (can't post link):
Frequency
LTE: 1, 2, 3, 4, 5, 7, 12, 13
According to this Network signal guru app, it looks like my T-Mobile version of the Z2 Force supports band 20.
Thanks for the info. I found on Reddit, that it should work like this: T-mobile only lists the ones it's network uses. If it's roaming it will use the other bands, or if you flash unlocked firmware it will be able to use those bands as well.
So according to this, the "other bands" should be listed on every phone's tech specs T-Mobile website.
I've been toying with crossflashing a G710PM (Sprint) to various firmwares to find which ones support VoLTE and WiFi calling on T-Mobile USA. I started with the Sprint firmware (didn't seem to support either VoLTE or WiFi calling on TMUSA), then I crossflashed to the European Pie release (didn't seem to support either VoLTE or WiFi calling on TMUSA either), then the Verizon Pie release (this one at least had an option for WiFi calling, but it appeared to be disabled), and finally the G710ULM10j GFI release (VoLTE and WiFi calling working fine so far).
Does anyone know if any other firmwares besides the G710ULM can do VoLTE and WiFi calling on T-Mobile and can be crossflashed?
Does crossflashing actually "enable" certain Hardware related features? Including "enabling" all frequency bands for GSM on a currently CDMA firmware? I didn;t think this was possible. I think I read somewhere that Tmo WiFi Calling feature is disabled even on factory unlocked versions.

I cross flashed a G710PM (Sprint model) to G710ULM (Unlocked Google Fi firmware) and so far VoLTE and WiFi calling work fine. Network Cell Info reported Band 66 for one location I checked (which the G710PM model doesn't support but the ULM model does according to their respective spec sheets), but LTE Discovery reported it as Band 4. I'm not sure which is right, but it seems that a misreport as Band 4 would be more likely than a misreport as Band 66 since Band 66 is a superset of Band 4. So I think possibly it actually enables the other bands, but I can't say with 100% certainty.
Interestingly, the bands listed for enable / disable in the engineering menu don't match either the PM or ULM models.
Edit: Forgot to mention, ULM and PM both support both GSM and CDMA. I think maybe only difference in specs is which LTE bands are supported.
AH! I've been trying to get to the bottom of this whole "what bands enabled/disabled for what firmware/carrier" thing for weeks now. Even LG is vague in their answers. Yes, you are correct, I'm finding alot of discrepency in the actual bands supported for which version all over the place. No one has a difinitive spec sheet. Where is this "engineering menu" you speak of? I'm getting really frustrated finding answers. Ya, i think the reason WiFi Calling/VoLTE are working on the GFI firmware is because TMO is one of the carriers Google Fi uses, so it has to work. Otherwise, Google Fi users would be upset a key feature is disabled. I bet if you were using the USA firmware it would be disabled. The key to my whole frustration is, like you mentioned, "WHICH" bands are supported. I have ULM.BPT firmware and am concerned if I use it with GSM carrier not all bands will be "enabled". Is this correct?

Honestly, when I downloaded the firmware I don't think I even knew enough about the regions to know there was a difference between GFI and USA. In fact, how do I check which one is installed? I looked in the version information in Settings and there's nothing there to tell me the region. It must be tucked in there somewhere? Maybe the BPT, USA, and GFI firmwares are all the same? I just downloaded both the GFI and USA releases from the LG-Firmwares website and the files appear to be identical. Maybe BPT is identical too?
Regarding the bands, I honestly don't know if every model supports every band or what the deal is. I've been happy with my cross-flashed Sprint on T-Mobile thus far, but I certainly can't say for sure if there are hardware differences that make other models not work with every band (or even if mine works with every band it's supposed to or it just happens to work well enough for my area). Most people seem confident the T-Mobile model is different, at least, but I think it's more of a mystery regarding all the others.
You can get to the engineering menu by using the built-in dialer and typing *#546368#*710# Then under Field Test -> Modem Settings -> LTE Band Selection there's a list of selectable LTE bands. I suspect, though, that everyone's has the same list (1,2,3,4,5,7,8,12,13,17,20,25,28,29,30,38,40), because that's the list I got on mine and it doesn't match either the PM or ULM model. I'm curious if yours is any different.

Ha! Thats my point! What IS the difference? Why have 4 versions if there is no difference in the firmware? Notice the updates are same for GFI & USA, so what IS the difference? Only thing I can think of is the Auto Switching software for Fi. But AFAIK when u put Fi SIM in it tells you to download the special software for that feature. Then notice the BPT & BPS have same updates. So, again, what exactly IS the diff? Notice it also specifically lists the "Product Type" as either GSM or CDMA. This is why I'm getting so frustrated trying to get to the bottom of this once and for all. All 4 are listed as ULM versions. Does this mean the 2 CDMA (BPT&BPS) will NOT have all the GSM bands 'enabled'? And vice versa. I'm going by this BTW:

Above in your list of bands: where is Band 66? thought that was a major TMO band? Ya, funny how the list doesn't match PM or ULM, huh? Again, my frustration. I bet you're not accessing all the TMO bands, only the ones shared with Sprint. (or the ones "enabled" by Sprint firmware) Like you said, maybe just lucky to live in area with good TMO coverage, so it never searches for other bands. U live in large populated area? Heard about the PM models being flashed to look like ULM? They seem to be sold on Ebay, Amazon, etc. Breed was company name. In my research, came across alot of buyers who were duped by this. Most saying they were having all sorts of connection/signal issues. Which proves just reflashing firmware doesn't "enable" more bands. I could be wrong. Your saying no problems at all. Also came across alot of VZN users saying problem with activating the ULM on their network. Which doesn't make sense either! Again, so frustrating getting to the bottom of this. I KNOW i read somewhere about the specifically TMO WiFi Calling being disabled almost everywhere except on TMO branded phones. (which would explain why it is working on your Fi firmware)

I'm just as confused as you are. As I mentioned, Network Cell Info says my phone was connected to band 66, which isn't available on the Sprint model. At the same time, B66 isn't listed in that menu. But then, B41 isn't listed in that menu, either, and that's supported to be supported on the Sprint model. So bands listed in that menu don't match any model that I'm aware of. Unfortunately the engineering menu code doesn't work on the Sprint firmware, so I wasn't able to check if the listed bands changed when I flashed over to ULM.
I've previously read the thread about the TM differences. I do know from looking at the FCC filing that the TM model has a different FCC certification number than ULM, so it's plausible that it is physically different from the others. However, PM shares a certification with VM and ULM, so I *think* they're the same hardware. That's why I'm wondering if *every* LG G7 lists the same bands in the engineering menu. Maybe that menu isn't actually listing all the supported bands for the specific phone?
In any case, the PM model supports bands 2, 4, 5, and 12, which is most of T-Mobile. Band 66 is just a superset of band 4, so most any B66 tower will offer B4 (though possibly at a reduced speed). So even if I don't get real B66, and instead just get the Sprint bands, that covers pretty much everything . Only thing missing is B71, which seems to be limited to TM model (which, interestingly, shares FCC certification with the Canadian model).
