No Voice over LTE - Nexus 6 Q&A, Help & Troubleshooting

So, I finally talked my wife out of her LG phone and got her an identical VZW Nexus 6. So we now have identical phones. I have unlocked the bootloaders, installed TWRP, and both are running CarbonROM weeklies.
For some reason, my phone has voice over LTE, and everything works just fine. Hers drops LTE every time she makes or receives a call. I've been searching xda and google for 3 days, checking and double checking that all settings match on the phones, flashing different radios, etc. And the setting for "Enhanced LTE Service" doesn't even show up in her settings.
If I put the preferred network to "LTE", (same as mine) she can't even make a call. It acts like it's going to dial, then drops signal completely.
Any ideas?

I would check and make sure Verizon has it provisioned to use volte

How would I go about checking to see if it is provisioned for VoLTE? It is on straight talk service now. When I contacted StraightTalk support, they told me that their service doesn't support it. And they didn't have an answer after I told them that mine does it just fine. LoL

Actually, they said maybe the phone needs an update...

Clarify the following. Are both N6es on Verizon, both on Straight Talk, or one on Verizon and the other on Straight Talk?
The last time I looked into it, Straight Talk didn't support VOLTE. Has that changed?

They are both on Straight Talk, using verizon sim cards. The tech support told me the same thing. That they didn't support VOLTE. And had no explanation when I told her that my phone was using it just fine.

It doesn't function on the AT&T side of Straight Talk and AT&T definitely has VOLTE. Thus, the fact you have it is an anomaly, and your other device not having it isn't an issue with the device or its firmware. In other words, consider yourself lucky.

Well, I'm not one to give up very easily. So, after some thinking, I may have come up with an idea.
Both phones were purchased from Swappa. My phone was listed as a Verizon phone, while the other was listed as an unlocked phone (no idea what carrier it was previously used with).
I'm thinking that adm1jtg may be correct, My phone would have been provisioned for VolTE, and the other phone may have never been on their network to get provisioned...
So, I think I will switch her to Verizon prepaid which doesn't cost much more and see if that fixes it. Maybe after a month switch back to straight talk. I will update this post afterwards, and let you guys know if that does the trick.
Maybe overthinking it a bit. After I switch her to verizon prepaid, and get her phone all set up and see that VoLTE is working, I'll pop my straight talk sim in it and let you guys know the results...

Soo... I had some time to think about it, and decided to just swap sim cards between the two phones. Turns out, it isn't her phone at all. With my straight talk sim, her phone got Enhanced 4G/Lte.
With her straight talk sim, my phone did not. Put my straight talk sim back in my phone, and Enhanced 4G/Lte came back.
Turns out that Strephon Alkhalikoi is correct.
I wonder how many BYOP sim kits I would have to go through to find another anomaly... LoL

[Q] Pure Edition AT&T Go phone

I recently purchased a Moto X Pure Edition and am trying to use my old gophone sim (previously in a feature flip-phone) in it. I have tested and confirmed that it works correctly on T-mobile, however when I put my gophone sim in it, it shows service for 30-60 seconds and then goes to "No Service" which I know is not true. It is also worth noting that I can't turn on cellular data. As soon as I do it turns itself off.
Other things that might be relevant:
My gophone plan is the 10c/min, no data plan.
This was originally a full size sim which I cut down to nano size. I have put it back in my old feature phone with an adapter and confirmed that it still works.
I have tried a dozen different APN settings, including copying the APN settings from a friend's Moto G that has the same plan, with the same result.
For the short period that I do have service, it usually works correctly. I still can't turn on mobile data, but I can make and receive calls as well as send and receive non-MMS text messages (MSS requires mobile data). Sometimes attempting to text/call seems to trigger me losing service, but that might be a coincidence.
I'm currently on rooted stock 5.0 lollipop with an unlocked bootloader.
Any ideas how can fix this?
I am going to try using my friends gophone sim and see if that works. I will update with the results of that.
Att contracts require data plan for smartphones. Maybe related. Call them and ask.
As I mentioned, my friend has a Moto G with the same plan. I did call and they suggested I get a new SIM. I'm going to do that, but I'm doubtful of the result

Help on getting phone working on straight talk.

Long story short. I was using a Verizon branded note 2 on straight talk when my contract ended with verizon. I grew tired of the phone and purchased the blu vivo xl from amazon a few days ago. Now I know that my sim in my Verizon wouldn't work on the blu phone because it's not compatible.
So I went on chat to switch my Verizon sim to an att sim from the same byop package (which also came with a tmobile sim) They said that it could take anywhere from an hour to 2 days to convert over, and that I'll know when it happens because my note 2 will stop working. Sure enough it stopped and a bit later my blu phone started getting a signal and 4G icon.
However, it was in and out all night and since then I haven't got it back. Frustrated, I then switched it to the tmobile sim. I get the 4G lte icon and arrows move up and down. My signal goes from 2/4 bars to 3/4 bars. Now I'm thinking good that's more than what att was able to do. Wrong. Well not completely.
I can send a text and my wife will get it. Not really slow but not normal. She'll reply and I can receive it. But I can't access the internet, and I can't call or receive calls. Went on chat they gave me apns to input and still nothing. I still get 4G icon and I still get service.
I really like this phone but this transition has been really draining.
Thanks you for your help.
I have no idea, I had a really smooth transition activating it onto metro. Maybe you just have spotty coverage with straight talk in your area? I'll try looking for more info

Correct. The phone is loaded with apns that matched what they gave me. The straight talk for att and tmobile.
So as an update, I bought a tmobile sim, (not straight talk this time) the phone received texts from tmobile for this and that. I have good signal as indicated from the bars. 4G lte icon is on (but no data due to not having a tmobile account, but the sim is allowed 30 texts and 30 minutes of talk time until I get one)
The problem that is persisting is that I cannot make a call. I'll dial any number between my wife's, friends even my own and it just gets stuck on dialing. No operator or anything just blank. It's flashing "dialing..." but it won't actually go and do anything.
I contacted blu, and they gave me the same apns that I used and assured me that it should work on straight talk. But yet still nothing. I contacted blu again after I got the tmobile sim. I'm awaiting an answer on that before I proclaim the phone a dud and exchange with amazon.com.

StraightTalk is owned and operated by Tracfone. I went through more blood pressure pills dealing with them than almost any other corporation. Best bet? Switch to almost any other carrier. I use Airvoice, but there are a BUNCH of others out there with no contract, pay-as-you-go programs. Truly, there are better deals out there than StraightTalk/Tracfone.
You are having issues (I think) because different phones available through Straight Talk work on different networks. They ask for your zip code and then show you phones from different networks that will work in your area. If you use a SIM card you are AT&T or T-Mobile. Sprint and Verizon use CDMA. Check coverage maps. This will explain why your coverage is spotty now. There is a list floating around out there that shows which networks use what phones and so on for Straight Talk. Once you put the SIM card in the phone, it picks up whatever network is available in your area. If it's a network that doesn't have great coverage where you are, service is diminished.

Restore wi-fi calling - carrier unlocked

Hi. I'm new (and old) so apologies in advance for any faux pas. I couldn't find another thread with a problem like this, so I'm posting a new question.
Here's what happened:
I have been using Ting MVNO SIMs on two Galaxy S8 phones for about 18 months. Preparing for an overseas trip, I asked T-Mo to unlock the phones so I could use foreign SIMs.
T-Mo unlocked the phones, but now I can't get wi-fi calling to work on the Ting SIM. Tried a MintMobile and FreedomPop and the same thing, no option in the tools or phone app to activate wi-fi calling although it is activated at the MVNO and the E911 addresses are correct.
T-Mo says it's impossible that unlocking did that. Well, it happened. Ting doesn't have a clue about how/why it happened or how to fix. Samsung says it's the carrier's problem not theirs.
I factory re-set hoping it would restore the lock, but that didn't do anything. I don't get a signal at my home, so wi-fi calling is necessary. My next step is to buy new phones.
Ideas? Thanks!

Unable to get wi-fi calling activated on Straight Talk network

Just got my Pixel 5 today and in reading up on it I discovered it has wi-fi calling capabilities. While this wasn't something I was actively looking for, it would be nice to have as the finished basement of our new house doesn't really get cellular signals, and even the rest of the house doesn't have the greatest cellular connection.
I do have wi-fi all throughout the house though, so if I could enable this feature it would be a bonus. I'm on Straight Talk, using the AT&T towers, and I'm just wondering if anyone has had any luck getting this feature activated with them. I've tried using their automated tool to see if the phone is capable, but it's telling me no. I don't see any options looking through the phone settings, and looking around on the ST site they don't mention the Pixel 5 in their FAQ section.
So is this phone feature only available on certain carriers? Do I need to get an updated SIM from Straight Talk (the one I'm using I've had for about 4-5 years or so)? Any help would be appreciated.
AT&T is very particular about what devices can use VoLTE and VoWIFI. i've found occasional workarounds, but for the most part you need an AT&T branded device for those features. AT&T has a running list of provisioned devices.
I'm afraid you are probably out of luck on this.
Too bad to hear this. Luckily, I've been surprised to find that I'm able to actually make and receive calls, at least in the main living area of the basement, so everything worked out okay in the end.
I can't promise you that it will work but from experience I'm pretty sure ..... If you can get customer support at ATT to provision your account for wifi calling AND put a dummy IMEI in your acct from a device that does wifi calling (one that is whitelisted by ATT) the wifi calling will work ..
I have done this many many times. The dummy IMEI had actually never been needed with pixel devices though, for me

Would that even work in my case though, since I'm not an AT&T customer? I have Straight Talk, which is using the AT&T bands/towers, but I'm not technically with AT&T.

Not sure if calling Straight talk sand using an IMEI from a phone that normally does wifi calling with ATT would work or not. Go to an att and copy the IMEI of a demo phone then call straight talk and switch to that phone

I may have to try that if it really starts becoming a problem. Surprisingly, as I mentioned above, I can actually make and receive calls in the main part of the basement. Maybe because it is the house above us, and not mostly the garage/solid cement like in the other portion where I was having trouble before, I'm not sure. It's pretty much just storage rooms in that section of the basement anyway, although that is where the internet comes in and the modem is located (the house is fully wired for internet, so I have a switch that feeds out from the basement to go throughout the house). Only time it would really become a concern is if I have to be on the phone with our internet provider while simultaneously working on the router or modem. Barring that, the phone seems to work fine throughout the majority of the basement, which wasn't what I was expecting.

Enhanced 4G LTE Mode "in" Mobile Network setting, and CDMA-1xRTT instead of LTE in Mobile voice network type in SIM Status

So, my wife and I have had two of these phones, Moto G6 phones, for about 4 years. And in that time, they've worked great using the Straighttalk (verizon) network. Recently though I switched to the Mint network because they said my phone was compatible ... even though it looked to me that they were a GSM. They also indicated I was in a great 4G coverage area. But, Coverage was terrible. I couldn't place calls in MANY of the neighborhood locations I used to be able to with straighttalk. And, other people said they would call me and they would never hear my phone start to ring. Nor did mine ever show I missed their calls. It was difficult but I finally got my phone switched back to straighttalk. But ever since then I have found that I can't place a call or text out in places I used to be able to. This has been going on for a few months.
Recently I was comparing my phone screens to my wife's and found two items that are different, when I think they should be the same.
In mobile network settings my phone does NOT show Enhanced 4G LTE Mode whereas my wife's does. It's simply not on my screen of information.
Also, in my SIM Status, my phone indicates the Mobile voice network type is "CDMA-1xRTT" whereas my wife's simply says LTE.
Are either of these two settings responsible for my not getting good calling service, and if so, is there a way to change my settings to hers? There is nothing I can see anywhere that I can change in all my settings that seems to effect this.
Do you think doing a factory reset my get me back to Enhanced 4G LTE Mode? I vaguely recall that the Mint sim was making some kind of changes to my phone.
Any other ideas?
Mint is obviously a GSM network since it's based on T-Mobile, and it works quite well on my G6, unlocked and bought from Motorola directly.
If you have a Verizon phone (which that CDMA-whatever talk sounds like), then you're going to need to stick to Verizon most likely. I have no idea if there is a Verizon specific G6, but I bet there is. RedPocket has Verizon options also if you are looking at cheap MVNOs.
And of course, using an MVNO you need to make sure your APN is right.
