Ok. So, I travel extensively for work, and for personal reasons. My 3 bases are: Australia (Vodafone), The Philippines (Smart) and Taiwan (CHT).
My OnePlus 8 Pro, in its current state (Stock, Dec 2020):
1. Will not get VoLTE on Smart in the Philippines, even though Smart has released VOLTE for all users. I do have the toggled enabled with logkit, but since I am on OOS11 now, I CANT get into PDC to try a different VOLTE profile. I am here right now, and this country VOLTE is critical as 3G is so slow - cant even google a phone number when you're on the phone....
2. In Australia (travelling home soon), my current network is Vodafone, where 5G AND VoLTE is working, although, that may be due to coincidence rather than design, as the largest network in AU, Telstra, up until OOS10 was working with 5G and VOLTE, and both are now not working on OOS11. So it could just be another update away for Vodafone to lose these for 8 pro users.
3. In Taiwan, VoLTE less critical as 3G is pretty solid, but, I've never been able to get it to work on recent phones in recent years.
Given that the compatibility of VoLTE / VoWIFI and 5G is seemingly a lottery, is there a ROM or Mod Out, that can:
1. Hide root from key banking apps / netflix widevine certification.
2. Give the user a higher degree of compatibility with international networks (happy if there needs to be a config change, or whatever, and even XML edits).
Back in my HTC days, there were a number of ROMs that had these features baked in by ROM makers. Wondering if same.
If you have root you can use adb shell to enable serial connection for PDC:
adb shell
su
setprop sys.usb.config diag,serial_cdev,rmnet,adb

Thanks for that. I can't run root typically, as banking apps, etc are critical. How are the techniques for hiding root these days?

I have been trying to get wifi calling with AT&T is working on my International S7 edge. I have made headway.
1. First of all I told AT&T I had their branded S7 edge and gave them an IMEI that will show up that phone. So I can activate my phone.
2. I have narrowed down the required apks to the following, but some are obviously for the Wifi Calling, and other's I am not sure. If people know what some of these apks do, please let me know.
3. I have used the Note 7 Port and flashed TTKG CSC selection and chosen the ATT CSC, we are still working on getting it working in the S7 and Edge CSC.
4. The following APK's I feel are related to Wifi Calling are.... If you can help me eliminate some that aren't. They are deodexed, and I have uploaded them, you will need to change the permissions to match the ones in the system folder.

5. I am unsure if I need to make Buildprop changes or I am missing other system files. I was able to activate wifi calling and turn it on, but it doesn't work.

Did you ever get this resolved? So far I can not for the life of me, get WiFi Calling working on my S7 Edge exynos. Basically throws an error stating the activation failed, and never brings up the screen to enter in my emergency contact address like AT&T is supossed to re-direct you to.
The activation fails because AT&T doesn't have an AT&T wifi capable phone on your account which then allows you to activate the wifi. I have two imei's that are linked to AT&T s6 and s7. I can give you the imei. Go to att tech support give them the imei and tell them to update your account to be able to get visual voice mail and wifi calling. After you do this, they will alow you to activate it. However I gave up after a while. If you flash the custom csc, you must do it before your phone boots up after a factory reset and flash a custom rom. I am waiting as I am on Nougat now, so until ATT updates it's apps again.

Thanks, although I'm a bit confused on the steps your outlining here. I assume you're stating that I'll need to somehow modify a ROM (in this case SAC's N7 ROM for S7 Edge Exynos), and inject an IMEI? I'm not entirely sure how to do that to change the IMEI (this would be my first time attempting to do that). Then I would reflash that image, and then re flash the CSC update to AT&T? Maybe I'm not understanding, but my iPhone 6 is on my account and fully capable of wifi calling. In fact we have 2 iPhone 6s on the account. What exactly did you give up on?
Hate to sound like a newb here (although in a way... I am), but can you step me through the process so I can follow your line of thought? Appreciate the help!
So first of all an Android WiFi Calling and IPhone Android WiFi calling are different you will need to tell at&t you have an AT&T branded Android phone that has WiFi calling. This will lead at&t to add the ability to add wifi calling on your account.
Have you rooted your phone and installed a custom rom? If so then you would flash ttkg84's csc package and choose att. Which will flash most if not all the files. I got all the way to confirm my address and enable wifi calling, but it never worked.
Do not insert another phones imei into your phone, you will brick it and will have a expensive paper weight.
I have given up for now and am waiting for a full release of Nougat.
PM my I can give you am imei to give AT&T to enable video calling, visual voice mail and give the ability to activate WiFi Calling, but it's not likely to work. Some things are still missing.
You may never get wifi calling working because at&t uses a slightly different method then everyone else. I think they will standardize with Nougat.

That's what I thought.... So what about the King of Nougat ROM that's lingering out there currently? I realize Nougat is still beta, but have you tried the beta?
I haven't tried King of Nougat. I am currently using Nougat? Are you on telegram?

So... Interestingly enough. I just got WiFi Calling to work this morning...
Basically, I did the following steps:
1. No SIM Inserted into Galaxy S7 Exynos - SD Card only
2. Reboot to Recovery
3. Wipe
4. Download and Install SAC23's Full n7 ROM located here: http://forum.xda-developers.com/s7-edge/development/rom-n7-rom-port-romcontrol-t3430358 - I did the V8 Debloated version
5. When prompted - Wipe Dalik
6. Insert SIM Card from AT&T iPhone (ensured WiFi Calling was turned OFF on the iPhone prior to removing from iPhone)
7. Reboot first time into N7 ROM
8. Go through the setup and connect to a WiFi location that you know WiFi calling works at.
9. Download a browser (Chrome or whatever) at a minimum
10. Eat a Bacon, Lettuce, and Tomato Sandwich :good:
11. Reboot to Recovery
12. Flash CSC for the N7 located here --> http://forum.xda-developers.com/note-7/development/utility-flashable-csc-selection-v1-0-t3450911 - Grab the CSC snapdragon the Exynos zip
13. Reboot
14. Status bar will indicate VoLTE enabled up at top eventually.
15. Try going to the pull down from the top, and clicking WiFi Calling option a couple times.... no dice.
16. Try going to the phone app --> Click Settings --> Note WiFi Calling is off --> Try clicking it on a few times.... you'll get an adroid app stopped working.
17. After sitting on this sceen for a few minutes, note the VoLTE dissapears, and the icons on the phone app screen (The Call Start Button and the Call End button) switch to WiFi magically.... Try making a call with 0 zero cell reception, and indeed, the call is being made through WiFI on AT&T's network.
Now.... I have absolutely zero idea what's going on with the VoLTE icon disappearing.... and the WiFI calling suddenly working. If you reboot the phone, the same thing occurs. It starts in VoLTE.... and then eventually disappears, and eventually after a couple of minutes being connected to a WIFI connection, switches auto-magically to WifFi calling.
I'll take some screenshots.

Followed the method above using Superman 1.16 and CSC selector 1.86.
Haven't been able to test wifi calling since I haven't found an area with wifi and no cell reception, but so far everything looks like it's working.
Important to note that the AT&T account probably does need to be provisioned for a G935A rather than G935F, which is done by reporting a G935A IMEI to AT&T (and not changing it on the device itself) as mentioned previously.

Hmmm, gotcha.... but if you report a G935A they typically want you to power off and power on the phone to check the provisioning while on the phone with them. And what happens if someone calls in and then tries to re-provision the same IMEI on another account? What happens to my SIM in my G935FD? Thanks!

Far as I can tell they don't check IMEIs against different accounts.
I can't say for sure, but I haven't had an issue as my phone has a different IMEI (or IMEIs--G935FD) than the one listed on my account (which reads as a G935A).
In short, asking AT&T to change the IMEI on the account hasn't affected or changed the IMEIs on my phone, or caused any problems.
As far as provisioning, I told them I was on the phone, so they called me back a few minutes later and didn't report any issues or discrepancies to me.
It'd be just as easy to tell the rep the phone isn't available though, so just ask them to change the IMEI and you can call them back later if there are issues if that's a concern.
Looks like great news. I was happy I was able to activate my 935F via AT&T (I gave them the actual IMEI and they activated it). I'm on Superman ROM and flashed ATT CSC. I get visual voicemail and the WiFi calling button, but it doesn't actually work. I'll see if I can get a valid 935A IMEI and ask them to activate again. Hopefully that will do the trick. I get a horrible signal at home, and the 4G/LTE icon is constantly flickering on and off... AT&T Video call option shows up in settings, but won't turn on... no wifi calling setting in the settings menu, just the quick settings button.
Any guidance appreciated!

I just got me new Oneplus 5 and my carrier supports wi-fi calling but only on a very restricted amount of Android devices like Galaxy S6/7/8 so no official support for Oneplus phones but is there any way to force the activation on the 5 with an app or something else if you have a rooted device?

Wow, that sucks if it's true. Do you know if it works on unlocked versions of these phones? If it doesn't, it could be something the carrier added.
Just to rule out the obvious... You need to manually enable WiFi calling on OP5. It's a toggle switch in the "SIM & network" section in the settings menu.
If that doesn't do it you might try editing /system/build.prop and changing ro.product.brand and ro.product.model to a known working model.
No setting option to enable it is there on the OnePlus 5 but same Sim in an S7 has the option to enable!
I will look at the build prop
Let me know if that works.. ?

IMS dictates WiFi calling configuration. Hopefully you can spoof the device into thinking it's an approved one for your network?
I have the same issue on my networks in Canada. It's restricted to just a couple devices and when I did the build.prop edits I got the options but when I turn it on nothing happens as in Canada we need to accept a user agreement for it and that never comes up for me to activate it. So I either need to do that on an approved phone or live without it

What did you edit in the build prop file to get the options to show up?
If you could give the exact entries that you changed and to what then that would be very helpful.

I have EE WiFi calling on me 1+5 and I'm rooted? The device deffo has if because you can get a VOWIFI status bar icon....
I think I enabled it on my sim prior to root though.... Dunno if that makes a difference as maybe registers again IMEI? I don't see why root would make a difference though

It is not root making a difference it is you would probably need root to enable you to activate something on the phone if your carrier is not supporting the OnePlus for wifi calling!

persist.dbg.ims_volte_enable=1

persist.dbg.vt_avail_ovr=1

Then this allowed the VolTE and WiFi Calling setting to show up and I can activate it but when I try to make a call it still seems to go out over Cellular network and no icon in the status bar to say that it is active etc.
This is the details of my carrier and wifi calling instructions etc.:

I suspect there are some firmware files missing which it needs to use wifi calling, you could do an adb log cat to a file whilst making. a call (you have to be tethered to your pc) so you can post the logs here to see if anyone can help.
You could try using Hangouts as it uses wifi for calling etc
I'm on AT&T and I got my phone a few days before I actually switched to it. When I went through the settings without a sim inserted, I know I saw an option for wifi calling and enabled it. Now with the sim card in there, there is no trace of this option. I will be watching this thread now, as I've been pondering paying for a microclimate, but if this gets figured out, then I'm good to go.
Yes I have read many articles including this one before posting.
https://forum.xda-developers.com/v20/help/lg-v20-us996-updates-vs-carrier-models-t3635327
As a prior user of the excellent unlocked only XT1575 Moto X Pure, I was expecting my used US996 to have no issues with Verizon.
Besides the fact you cannot even activate the phone directly without having an activated Verizon SIM already, the phone works excellently apart from Wi-Fi calling being conspicuously absent.
After using the Quick Shortcut app to access the various Wi-Fi calling areas in the deeper part of phone functions, as well as the "WiFi Calling provisioning" (in the hidden info menu that just turned itself back off)
I have grown frustrated enough to look up a deprecated Magisk module that it's originator claimed does not work but some others have supposedly had success with - voenabler.
This finally leads me to calling Verizon & getting to actual tech support where the dude educates me on the manufacturer having to provision from the factory software the specific carrier approved/compatible functions including Wi-Fi calling.
This leads me to the point that if LG has any power whatsoever in this matter, can we petition them for the mythical Android 9 update to include VO Wi-Fi calling with Verizon & carrier compatibility so we can activate this phone normally?
Pie is not that impressive an update on it's own; if some basic functionality could be added back, it would be a boon to everyone that is still holding on to their V20's for as long as possible.
Probably aiming too high & if so, can I just flash the VS995 Verizon V20 firmware with my bootloader unloacked to retain root functionality?
Read a couple threads about successful flashing as the hardware is identical but no mention of unlocked bootloaders/OTA updates or Magisk root.
Cheers
If you were to figure out how to get this working, I'd be interested.
I am looking to by a device specifically for the purpose of modding rooting etc.
1st My biggest need is the ability to disable 5g radio when needed.
2nd Would like to remove any all ability of the carrier to monitor/control/dictate how I use my data. This may not be completely be possible but the goal is to find a viable option to using the buggy pdanet tether app.
3rd specific to this phone I would like to make sure I can re-enable the Infrared Camera. Herd it was disabled in a patch.
How much of this can be done with a OnePlus 8 Pro? Should I look at a different model?

You can disable 5g through the menus. There's also a setting called smart 5g or something which minimizes 5g activity to preserve battery life somehow.
Not sure about using your data how you want. A vpn may be able to help out with that. It's what I use and have had no issues with tmobile stopping me from doing my business.
I don't think there's an infrared camera, bit you can reactivate the monochrome filter dealt by some adb commands and it seems to be a good workaround.
Without the phone being rooted, placing an AT&T sim in my current Fold 2 results in the menu option to disable 5g being grayed out. This does not happened when I put a t mobile sim in the same fold 2. Just want to make sure that does not happen again so I was hoping to get a phone that is easily rooted and supported by the community which is why I am looking at the Oneplus 8 Pro. I also have and use VPN's, but that is not what I am trying to control. Basically ATT monitors all active interfaces on the phones on their network and can tell when I am tethering and how I am tethering. I want to make sure that if I root the device I can disable all this monitoring. I have and use PDAnet but its very buggy and not being supported it seems with windows 10. The 8 Pro does have an infrared camera, but that is really just a reason for me to get the 8 over the 7t...
I have discovered that while I can't disable the 5g radio I can, with an app, set my preferred connection method while on ATT to LTE. This allows me to connect to the faster LTE radios on the towers near me over the slower 5g radios. 5g support in my area is very poor so LTE ends up being considerably faster.
I appreciate the input though. Do you happen to know if you can submit AT commands on a rooted 8 Pro? At commands also called Hayes commands sometimes. This is the sort of low level configuration used to change or mask IMEI's, change lte bands, and most importantly strap or aggregate lte bands.
Hi folks, I would really appreciate some help (sorry for the long-winded post.)
I have an S7 Edge SM-G935W8 that I received as a "hand me down". It was reset to factory and updated to the latest firmware last week.
The phone was locked to Tellus and, as a SIM card is required to enable the mobile hotspot, I had Samsung unlock the phone so that it would recognize my old Bell SIM card in order to enable the mobile hotspot. The SIM card is not provisioned as I don't intend on using this phone as my daily driver and I don't require internet or data. I simply want to use it as a backup camera for my travel trailer by setting it up as a mobile hotspot using the camera to stream to my tablet using IP Webcam Pro.
This setup works relatively well but I only have the 2.4Ghz band available to me on this phone, which leads to a slightly choppy stream. It's not bad, but not great. I would prefer to use the 5Ghz band since it has less interference and thus runs faster, which I believe would yield better video quality. That being said however, the 5Ghz option is not available under the mobile hotspot advanced settings on this phone.
I then decided to root the phone, which I did without issue by enabling USB Debugging and OEM Unlock in developer option. I then successfully installed TWRP and tried both Lineage 17.1 and 18.1 since the 5Ghz does show up under the mobile hotspot advanced settings. Great I thought as the video feed was indeed better! That was until I discovered that there are issues with the video camera with these versions of Lineage whereby it works fine for about 15 or 20 minutes then the screen goes green and you need to reboot the phone in order to get the camera working again. I tried installing Footej to see if that would make a difference but it did not.
Soooo, I returned the phone to stock with ODIN and we're back to where I was before. It's a setup that works but could be better. I read that the 5Ghz band could be enabled with CSC Features Expert but you need root. OK, so I go back into developer options to enable USB debug and OEM Unlock like I did a few days ago and lo and behold, it no longer stays enabled. The option is there, NOT greyed out or anything. I toggle enable, get the message about device protection... and an option to cancel or enable. I click enable and it goes on then quickly goes off again so it now seems I can't root the phone anymore
I've scoured this site high and low, googled everythhing I could think of but I seem to be running around in circles. I can re-install the latest stock version of the firmware from any provider in Canada (I've tried a bunch) but the same always happens. The OEM unlock options gets enabled for a fraction of a second then turns off again. Can this option be forced on using ADB or Fastboot or some other method?
My goal is to root it again in order to install CSC Features Expert so I can enable the 5Ghz band in the mobile hotspot advanced settings. It also appears I can't downgrade to anything because Samsung updated the bootloader in the latest firmware. ODIN fails at installing any stock firmware except for the most recent.
Any help would be greatly appreciated.
