Wifi Calling, Verizon Pixel 2XL, using Straight Talk AT&T Sim no option

Hey all, I've been pouring over the forums here and other places trying to find a solution to my issue. I just got a Pixel 2XL the verizon version and I'm using it on Straight Talk with an AT&T sim card. So far so good except I cannot get wifi calling. I'm pure stock, android 9/Pie, no bootloader unlocks/rooting etc. The wifi calling option does not exist in the phone app nor in the settings anywhere. Even when you search for wifi calling, it simply takes you to the network and connections section of settings but wifi calling is no where to be found. I've tried the adb command (the one that apparently used to work on Oreo but not longer does on Pie) and that didn't work (though I didn't expect it to since many people said it no longer works on Pie). I have an Unlocked Note 9 as well and its wifi calling works perfectly fine so does anyone have a way to make this work? Reception at my home is somewhat lacking and I really need wifi calling.
Thanks!

Could you attach a screenshot with the WHOLE section of "Mobile Network", found inside of "Network & Internet" in the Settings -- make sure that you click on the drop down menu next to "Advanced Calling" -- this will help make sure that wifi calling is really missing as well as might point something out that may help with a solution. Moreso, personally, because I can't even imagine what the settings menu looks like missing this...

It might be a long shot but try checking the settings in the Google phone app. There should be a place that says configure IMS calling. I have this setting here and in the network settings. If you have it that's where you can enable wifi calling.

Been there done that. I have no options for setting up IMS calling. I only have SIP options. Also, I have tried the phone dialer trick (where you dial *#*#4636#*#*) and that shows the wifi calling option as a toggle but its greyed out and cannot be enabled. I even tried an adb trick that used to work on the 1st gen pixels, but to no avail.

What happens when you enter your information here?
I'll have to initiate a chat with Straight Talk. Like you I have a Pixel 2 XL with a Straight Talk AT&T SIM. The only difference is that mine is unlocked. I just ran my phone number and the IMEI of the SIM through the linked site and it tells me my device is not compatible. Since I have a BYOP SIM and the IMEI is of the SIM itself, chances are high that the SIM needs replacing with one that includes WiFi calling support.
EDIT: According to the representative I just spoke with, there's no guarantee that changing to a newer AT&T SIM will enable the feature. The only guaranteed method according to tech support is switching to a T-Mobile SIM.

Hey thanks for the help. I tried that link as well (before I posted here; sorry I should have mentioned it) and it said my device is also not compatible. I initiated a chat with them and they told me the same; switch to T-Mobile. I am tempted to do so but the one thing holding me back is my home is already a place I get poor signal and T-mobile's coverage while much improved still isn't as good at AT&T's. I realize that having wifi calling would fix any lingering signal issues but I do manage to get 1-2 bars of 3G at my house with AT&T, I figure I won't even get that with T-Mobile. So I am weary of the switch. I'll have to consider it though. I could also wait for the full rollout of the latest google voice (since it finally is bring VOIP without the need of hangouts) and just use that number instead.

So I contacted Straight Talk and ordered a T-Mobile sim card. It'll be here in a few days. I will post my findings after it arrives. Straight talk support says wifi calling works with all T-Mobile sim cards so we will see.

Hello all,
Okay, so I finally got switched over to a T-Mobile sim card (again still with straight talk). It took a while cause I had to buy a new one (the old one I had expired; who'd have thought?). Anyways, switching to T-Mobile solved all my problems and then some. Not only do I have Wifi calling, but also HD voice, VOLTE, Tethering, and 3-4 bars of LTE (previously on AT&T, I got 1-2 bars of 3G). I realize the signal issues is merely a coverage thing but I can say with certainty that switching to a T-Mobile sim card will give you all the advanced features. I hope this helps others who might experience this problem. I've been using AT&T (in one form or another) for the better part of a decade and can now honestly say, AT&T sucks.

Is your download speed throttled?

VOLTE

So I stumbled on the fact the Note 10+ has this feature out of the box a few days ago. It's not in the usual spot for Samsung for me, but when I flipped it on it worked. I've changed nothing, but it no longer turns on (reboot, airplane mode, PRL and Profile Updates. Switch goes to On, It tells me how amazing VOLTE is, but then I don't get the VOLTE symbol in the status bar and still loose data on a call.
Anyone else experience this?

Well for anyone who cares, I have a Sprint Magic Box. I've seen mixed information on it, some places stating that the older Generation units will support VOLTE and it's been rolling out since nearly a year ago, other sites stating only the Gen 3 support it.
I contacted Sprint and they seem to claim the later, that only the Gen 3 supports it. Since I have a Gen 2 they are setting up to swap me to a Gen 3.
So FYI if you have Sprint and no VOLTE, this might be why. If you have Sprint and have VOLTE on a Gen 1 or Gen 2, definitely congrats on hitting the lottery!
Only other thing I can think of is they started updating older units and had issues and stopped. I've had the Gen 2 exactly a year and a couple days.
Edit: From further reading, the magic box software that supports VOLTE is 15.15.50.514 which mine has and it does not support VOLTE. So *shrug* not sure what happened.

I have Sprint and have VoLTE

odd, the exynos EU/UK version doesn't have a VOLTE symbol but VOLTE works fine on THREE UK out of the box.

I have the unlocked 10+, I have VOLTE on, can place calls and use internet without and issue, but no VOLTE symbol in status bar. Using Xfinity Mobile(Verizon towers).

For my brother's and sisters with an unlocked phone and on AT&T there is hope for us to get VoLTE without wonky work arounds.
I called and called and called and finally got transfered to someone who could do something. Basically AT&T will at first tell you that features like Wifi calling and HD Voice (VoLTE) are only available on AT&T certified devices aka phones you bought from them.
However what they won't tell you is that if you press them hard enough and get the right person they will add your note 10 plus IMEI number to their internal IMEI devices database that allows your phone to get all those sevices.
Now it's not instant they will advise it takes between 24-48 hours and for me it took about 30 but as I was sitting here about 20 min ago I got a notification about a carrier services update and after it applied it I had the VoLTE toggle and wifi calling toggle on my unlocked note 10 plus. I of course turned them on right away and after confirming my e911 address I had wifi calling and shortly after VoLTE started to work.
The difference in call quality between standard cellular and VoLTE blew my damn mind. It's a real shame AT&T plays these games but you can get your IMEI added and get a the features without having to flash the att firmware or do sim swaps.
I haven't tried making a video call as all my contacts have iPhones but supposedly it's enabled now too

With a Gen 1 or Gen 2 magic box? Otherwise you missed the point of the thread entirely.

Now if they could just enable VoLTE on the Galaxy Watch...

The UK version from Samsung does have the symbol, I changed fro EE to 3 over the last couple of days, when I was on EE I got the volte symbol but on 3 I don't, so while the option enables I'm not sure it's actually working. But the same is true with EE I always had 4G+ but on three I only get basic 4G.

I can confirm VOLTE and WiFi calling works perfectly on three. When u place a call the 4g symbol remains as 4g which is basically a VOLTE call.

I've been on the phone with them (AT&T) for the last 4 hours! They had the WIFI Calling working, but when I called back about the video calling and VLOTE they screwed my Wifi Calling back up. They went on to tell me about how my IMEI isn't showing up as a Note 10, but some other device named Nubia or something. I know it can be done, because I had it done with my Note 9. I had enough for today, I'll try again tomorrow!

I had to call in a number of times before I finally got someone who knew what to do. They have a BYOD device program and getting the IMEI added is part of that program.
I am running the unlocked firmware, with AT&T service and I have all advanced features like VoLTE and Wifi calling.

Can ou provide several screenshots of proof you have it On? and what are the steps you have to mention to the customer service or their technician?

Wow! I never realized this. I tested what you said and I can be on a call and the 4G symbol stays active, so I assume I am using VOLTE as well?
Oddly, I do not have an option in the Mobile networks to turn on or off VOLTE. I'm using a Sprint purchased, unlocked Note 10 plus on MetroPCS.

Great so it's working. In the UK they don't have a symbol saying VOLTE the icon remains as 4G on a call same in Japan and Korea. Sometimes it may say HD by the mins and sec call timer

Correct, I get the "HD+" next to mins and sec like you said. Just don't have the option and do not see VOLTE anywhere. I'm perplexed why some have the option to toggle VOLTE under connections, and some do not. But I guess the important thing is it's apparently working

It's an unlocked non carrier device and the USA networks are well known to behave in odd ways such as compelling Samsung to make carrier specific software and bloat on devices. Maybe its to do with that. Most global GSM networks are significantly more 'chilled' that the USA networks. Its quite laughable in some ways

Note 10+ newbie here. I have a MOW N975F which is unlocked, but not the unlocked US version from Samsung.
I came from a Note 8 and on that phone I had called them and given them an IMEI of a real ATT sold phone and upon reboot, I got the Volte toggles, but no WiFi Calling toggle and video calling does not work on the Note 10.
So when I switched the SIM to the Note 10, I too get the 4G icon instead of the 4G-LTE like on the Note 8 previously. Volte seems present, but Video calling does not work on the Note 10. It tires to place a call and quickly terminates with some kind of network error.
I did not yet attempt to call T again and have them change to the Note 10+ IMEI under their BYOD program.
I am wondering if anyone has come up with a method to get the real AT&T CSC? On my Note 8, someone pointed me to CSCSelection_S7_S8_V1.2.5_Note 8.zip and that worked perfectly. Seems there is no more OMC directory on the Note 10 and the above did not do anything.
Might there be a way to flash through ODIN the AT&T CSC stuff from a T ROM?

Can't connect to mobile network.

I have a pixel 3xl, up to date stock non rooted, on straight talk lte/cdma Verizon network. I got a text saying straight talk now has VoLTE so I tried to find it in settings but there's no option for it. When I search it it comes up but when I click it it goes to mobile settings and it's not there I did the *#*#4636#*#* and it's also grayed out there. I changed the network mode in that diag screen to lte/cdma to see if that helped, was on global before i think. Still no VoLTE and for some reason I can't make calls. I have data, can send and receive texts but when I go to call it says no network. Removed Sim card didn't fix it, restarted it. Safe mode doesn't help either. Tired clicking trigger carrier provisioning, updated the smsc. Change mobile network to lte only, back to global, lte/cdma. I have no idea what else to try. Straight talk is basically useless for customer service so I haven't even tried yet lol.

Update!! It works!! Somehow I either damaged my sim card when I switch from my pixel 2xl to this 3xl and it somehow lasted till now. Or when I changed my network settings something wrote to the sim?( And it messed it up?? IDK much about how the phone and sim interact with each other)... But I did have a 2 year old sim card, it did not have VoLTE or wifi calling capabilities I now realize. So I bought a new SIM card at Walmart and activated it though the straight talk app on my account and kept the same number. Works perfectly and I now have VoLTE, no wifi calling yet but the option is now there and lets me click it but it fails. Doesn't matter to me, I'm just happy to have VoLTE. I'm leaving this post because straight has horrible customer service and I could find anyone who ran into this specific issue.

Trying to Configure Note10+ 5G (N976V) with Visible but can not add APNs.

Trying to Configure Note10+ 5G (N976V) with Visible but can not add APNs. The option is Greyed out. I was able to do it with my Verizon S10 that is also not officially supported. Crazy thing is that for about 5 min i was able to use the Visible SIM in my Note and Call and Send Txt until I rebooted the Phone. The Phone is paid off and Im using it on Mint Mobile now but it doesnt Show the T-Mo Boot Logo when I switched SIMs like my S10 Did. Has anyone been able to get this to work. I was told by Samsung that I may need to Reflash the Phone.

i have the regular unlocked note10+ working on visible.

N976V on Visible.
I am having the same issue, the APN settings are disabled. If you get this resolved before I can figure out a work around please let me know. Thank you.

Did you work it out? if yes, can you share how?

As soon as someone has resolved this issue, please update this forum page!

I just upgraded my note 8(on Visible) to the note 10 plus 5g. After i put in the Visible sim card into my note 10 phone, the phone was not working with the Visible sim card. I was connected onto the wifi network at work and I went into the settings to update the APN information, but it was greyed out and could not enter that information into the phone. After a few hours of googling to see if I could fixed the greyed out APN area so that I could actually enter in the programming, I said let me check the phone outside with wifi turned off. I went outside and tried to place a call and the call connected. I was then able to get wifi calling turned on since the phone was not allowing me to do so before. I went back into work and tried to place a call on the wifi network and it worked. I also tried sending text messages and mms messages and they all work. I checked the settings under the APN area and the phone automatically populated the Visible Internet setting but it was also greyed out, but it was working and I was so happy. I am so happy now with my new galaxy note 10 5g phone that is up and fully working with the Visible sim card. So I believe that having the phone connect onto the cell tower signal and not the wifi allowed the phone to pull in the APN information that it needed. I also reset via the setting the network connections while I was outside a few times. Hopes that this helps...

Change CSC with SamFw Tool (don't brick your device!!!)
Don't update beyond U4
Unlock bootloader and root.
Modify everything.
Accuse Samsung of being stupid for ever creating such a product with such limitations.

AT&T VoLTE is possible. Just got it turned on

I was finally able to get AT&T to get my VoLTE turned on. It took two chat sessions but finally I got them to turn it on.
VoWiFi... not so much. They wanted me to go in to a store, because the phone isn't an AT&T sold phone. The chat representative said they would do something to the phone to turn it on even if the VoWiFi switch is already turned on.
Side Note for VoLTE:
My suggestion is tell them you used the dial code "*#*#4636#*#*" and tell them you can see that the VoLTE isn't enabled. And if your phone isn't registering with the IMS info, let them know too.
Good Luck
Anyway here are the screen shots:

You sir are a saint, thank you so much for this helpful information.

That dial code doesn't do anything when I type it in for some reason.

I was able to get VoLTE on both mine and my wife's OP8 Pro by just having the phone agent register the IMEI and rebooting.
I have submitted a ticket with their advanced team for enabling 5G provisioning since we have the 5G bands (or at least one of them) for AT&T. I will follow up if I am successful.

yeah I came from the Note 10 5g on ATT and i didn`t have to do anything, I just put in my sim and turn on VOLTE and it just worked. but Vowifi is another story. lol, I`m going back to Tmobile in couple of months, at least they allow vowifi and 5g to work without the BS from ATT

Will be trying myself and will post if make any progress

I ended up with a MVNO provider Ultra Mobile as a 2nd line on SIM2 (need a 2nd line for work anyway). That gives me 5G+VoLTE+VoWiFi unlike AT&T.
really wish AT&T business practices change. It sucks that AT&T does their customer like that.

I have enabled Volte via PDC method, disabled overseas commercial and activated CU-LTE.
Everything works great.
