Hi,
I opened another thread regarding safest method to change from unlocked stock os to the T-Mobile release for Wi-Fi calling, possibly in wrong area as somewhat related to T-Mobile, however my main worry is ensuring I will have full 4g/LTE support, I am awaiting a sim card of a T-Mobile mvno, but I've seen several places I'd likely not be able to even use 3g without enabling the bands required, I've come across various guides .
Several said to use ##3424# or something alike(I'm out right now so can't confirm) to get into diagnostics, this does not work, I can however use the *#*#3424#*#*(again might be incorrect code) however this is self check options and to calibrate vibration etc, unable to connect with qpst with this.
Any help would be helpful, I purchased the phone second hand unlocked to use when I visit the US, I know it's unlocked and works in UK, just require it for use in US as I use an m9 as my main phone.
Would be nice to get the Wi-Fi calling function but not important.
Any help on how to go about this would be great.
Regards,

Well I Have A T-Mobile RUU Thread I Made That You Could Use, It's Not Set For The US Or UK, Just For The T-Mobile Carrier
You Would Need A Windows Computer To Do This Tho. Reply Back If You Want The Link
Is or has anyone else been able to get VoLTE working on T-Mobile US on this model specifically? LTE and WiFi Calling work in general, but the "Enhanced 4G LTE Mode" toggle isn't there to allow VoLTE. The model has the same number of bands as the XT1710-01 model, but is on the RETLA channel, by the way.
Hi, actually I was having similar issues. VoLTE, seems to be different but is based on your Carrier mostly. If you call someone from a different carrier it may not be enabled. I'm with AT&T, whenever I call someone with AT&T and we are both with good 4g LTE, in the call, changes the status to HD. But, just with AT&T. At least that's how it Works for me. We should wait someone to confirm is this is how other carries behave.

Apologies for the late reply. Definitely no VoLTE or HD voice between me and other T-Mobile users. No matter what I tried it just never came up. If anyone's considering using this specific variant of the phone in the US, I'd be aware of the limits beforehand.

-06 is a North American dual sim variant, correct?
Are both SIM cards on t-mobile?
Could one use SIMS from different carriers?

-06 is a North American dual sim variant, correct. Updates should go through ATT Mex, I believe. And yes, you can use sims from other carriers. I used one sim card when I tried it and only utilized one of the sim slots as a result. T-Mo VoLTE just doesn't seem to have been certified for that variant.
So T-Mobile WIFI calling works on this variant of the Z2 Play? If so that is good to know especially when traveling overseas even if some other advanced features don't work.
I have an XT1710-06 retla device and I can confirm that wifi calling with T-mobile does *NOT* work on my device. There is a setting to enable wifi calling, but it never seems to connect and all calls still go over mobile. This is 100% testable if I for instance go into a deep basement that has wifi but no cellular signal -- I can browse the internet but cannot make phone calls or SMS, even though I have wifi calling turned on.
This is probably related to why VoLTE doesn't work either.
Also (as mentioned in another thread) still no updates for it past February 7.1.1 update. No later security updates and no Oreo updates.

Hi,
I'm super curious how did you get your Z2 Play to have VoLTE. I 've tried everything - new sim, IMEI of ATT branded phone, activated SIM on ATT phone, etc. , to no avail. I'm so frustrated and about to get another phone, because my HSPA signal is much weaker than LTE where I'm at and constantly have missed (straight to voicemail) or dropped calls. Please, let me know how did you get it to work.
Thanks
Maybe the problem is VolTE itself. As I tested. Unless both phones are with the same carrier and working good over 4G (good signal area) you can't get it working. At least in where I live that was true for a friend's phone and mine. So VolTE was good, until signal dropped hard. But impossible to work with other carriers.
Even it was good under Lineage OS and tested with Toxyc OS, but I saw the main thing is that 4G LTE should be firstly working fine. And same for anyone you call. Otherwise call will be normal. And for 4G LTE it depends on area support too.
Sorry for late reply

Same phone (XT1710-06 retla, rooted stock ROM on Oreo), and wifi calling on Tmobile also doesn't work for me. I can enable it in Settings, but I cannot send SMS or make calls over wifi with no cell service. After a while (a few hours) I get a Moto Settings notification that it can't enable Wifi calling, with a message underneath that says "Enabling." I can't dismiss the notification, only snooze it for up to 2 hours, and after I disable wifi calling it does eventually go away after a couple days.
Your problem is because none of the XT1710 variations have the 600MHz Band 71. It is the most recently added band and very few phones currently out there support it yet. As far as the HD voice issues mentioned...both people on the call have to be using a Volte supported phone and then HD automatically activates.
I have a Galaxy S9 (SM-960U) purchased from T-Mobile, but unlocked and running with an AT&T SIM (among others, at times). Up until today, the phone was running the stock T-Mobile ROM which received various software updates on a monthly or every two month interval. I've installed them as they were released (while running various non-T-Mo SIM cards) and the latest was October 1, 2018. Today, I clicked the "Software Update" function and saw that a new update was available. When it installed and restarted, I noticed that the phone was running an AT&T branded ROM, along with the typical AT&T bloatware (e.g., CNN, Groupon, Amazon, AT&T-specific apps) that was not previously installed.
The other thing I noticed was that the phone now is only connecting to HSPA and HPSA+ networks, whereas before it would also connect to LTE.
I'm not sure why I suddenly received and installed an AT&T-branded ROM today when my S9 and all of my previous devices were fine running the T-Mo ROM and receiving updates as they were released. Does anyone have any insights as to what caused this change and whether future ROM updates will be carrier-specific based on the inserted SIM? In the past month I've used SIMs in Vietnam and Japan and it seems odd that ROMs would suddenly be based on the carrier of the day.
Also, any ideas about restoring LTE service? I've tried removing the SIM and powering off the device a few times, but no dice. This was a network/account-problem when I initially ported over to AT&T from T-Mo which took a lot of troubleshooting at the store (unsure of actual root cause), but it seems odd that a software update on the device would undo that.
The latest update (3BRJ5) is BYOD firmware. With B firmware, a carrier sim will change the csc of your phone to match the network you are connected on. Good luck getting LTE back, I have no idea on that.
*#*#4636#*#* entered into phone dial. That will allow to select preferred network type in device information.

you have to change APN setting on the menu to reflect AT&T network. let me know if it works by changing APN.. I used to have S9+ tmobile and I was waiting for this BYOD update but i traded in my s9+ already =/ i have note 9 unlocked now..

The issue required a visit to the AT&T store, where they replaced the SIM and reset some of the network features on the back end of my account. This required a call to the retail technical support team and about 45 min. No settings were changed on the phone. The APN settings were already configured correctly (which I had confirmed as a part of initial troubleshooting).
The phone works fine now, though some features like AT&T HD Voice and the AT&T Call Protect app still don't work. I've tried contacting them twice about it and they opened a ticket but it hasn't helped. These aren't features I used before so I don't really care.

Keep in mind though that HD voice only available to postpaid At&t only not prepaid and they do required special sim card for hd voice but since you already changed sim card then the problem is not the sim card. You can try and dial #*#*4636*#*# and see if Volte is provisioned.. I wish i had my s9+ from tmobile but i dont have it anymore i was waiting for that byod software update.. Hd voice should work on BYOD custimization update on at&t
*********UPDATE********** I bought a new sim from straight talk and VOLTE works now! (GSM compatible Straight Talk Sim card) My old sim was from 2014, so it wasn't VOLTE compatible.
I have an ebay zombie LG G710ULM flashed to latest Google Fi Android 9 software, I received an email from Straight Talk (Wal-Mart US cell phone service reseller) telling me that my LG G7 does not support VoLTE and my phone will be unable to receive calls in January 2021.
-Using a network info app, the app is telling me it is connected to T-Mobile towers (so I have a Straight Talk T-Mobile compatible SIM)
-I can't find any options to enable VoLTE in settings, and wifi calling is erroring out
I was wondering if there are ways to get VoLTE and Wifi Calling working (Straight Talk supports it, but not my current ROM/SIM).
I can switch to the following sims supported by Straight Talk.
-AT&T Compatible Sim
-Verizon Compatible Sim? If my phone supports CDMA bands
OTHERWISE MOST OF US WILL HAVE A PAPERWEIGHT IN 2021!!!!!!!!!
Same problem
I'm having the same problem. Any progress on this?
I'd like to know this too. Surprised there is no traffic here with all the knowledgeable people on this forum.
G710EAW here. BTW There was an Android 10 update just two hours ago from Android 9. Someone with an 'EM' phone in another thread said VOWifi is "working now" but how do others know if it's working when January 1st comes around?

If you guys have cross flashed roms, then volte will not work. It doesnt work for any of us who have crossflashed. Whichever model.
You need to be on original software. Looks like some licensing thing that volte requires. They need to provision volte for all the phones. Sounds like they are not interested to provision it for g7. Odd that even EAW model which has original firmware, they sent that mail too....
Sad/Odd to see your carriers are suddenly changing to only Volte.
Is there a way to put it back to original software? I actually don't need it crossflashed to anything because it's a Verizon originally and I would like to use it on that network. Or does it not work that way?

Main issue is that your carriers dont want to provision volte for your G7s. So no guarantee if cross flashing back to original will work.
There is crossflashing guide in guides section with which you can go back to stock firmware. Do this at your own risk.
In our country we have a volte carrier called Jio. They provide an app called jiocall. Using that app you could use their service even if your phone is not volte capable. You will have to see if there are such apps for your carrier. Thats the only non technical, simpler solution.
I have some information that might make all of you guys happy.
I was told by Safelink Wireless that VOTLE is a function of BOTH the phone *AND* the sim card.
Basically, if the phone itself is VOLTE compatible but the sim card is not, then the phone will be reported on their system as not compatible, and will ask you to upgrade your phone.
However if a VOLTE compatible SIM is inserted, if the phone does in fact support VOLTE, it will then work. That's because it's provisioned on the carrier via the sim card itself.
If you purchased a sim via the "Buy your own sim" package, e.g. online or from Best Buy, etc, awhile ago, then that sim is not compatible. You simply need to call Tracphone/Safelink and ask to buy a VOLTE compatible SIM (which costs 99 cents). Then when you get it, call their tech department to have them transfer the phone service and phone number to the new SIM.
You can dial the phone's service menu and go to the VOLTE/GPRI menu and if the options are there, then the phone supports it.
What's the correct service menu number for our phones?

Update, I recently bought a new sim and I have VOLTE right now on ULM android 9 latest security fix LG G7 image, running on Straight Talk.
took a while to understand lgup but my 710 oulm had a type oreo that the guy said couldnt be but i crossed flashed it to 10 i dont see the rom anymore and i hope i put it on another drive it was a canadian rom for android 10 works great otherwise im looking to get volte active in the *#*#4636#*#* phone menu you can see "provision for the setting under the radio on off but its a grey area the buttons dont work could be good could be bad its definately part of 10 but ?? grey areas preferred network could be sketchy to play with the phone initially on transition had incredible link up speed now its giving me a pain because assume i played with the connection preferences tab and its a registration error like dum just use the assigned sim guys and stop trying to mac or identify with every device anyway its the registration of a telephone number robo heads
Hi,
I own an Oneplus 7T, which is VoLTE and VoWiFi enabled. Is it possible to make my network carrier believe I'm connecting with another phone model? Like a Xiaomi Redmi 10 for instance. I need my network carrier to stop disabling VoLTE and VoWifi from my subscription. It does so because I own a OP7T.
Here's the whole story...
The OP7T has two SIM slots and they are populated as so:
SIM 1: Orange Telecom (french)
SIM 2: Bouygues Telecom (french)
Orange won't recognize my phone as VoLTE or VoWifi compatible, whereas Bouygues does. I finally got in touch with a skilled employee there who told me that this is Orange's stupid politic to enable VoLTE only on phones they sell at their store! Gosh... There are some Xiaomi, Huawei, and fo course Samsung, Sony... but no Oneplus.
When I put my Orange SIM in a Samsung compatible phone, VoLTE and VoWifi work and remain ON, forever (I tried 3 weeks). If I switch to my OP7T, the VoLTE will work for 2 to 24 hours (very random) and then it turns OFF (only for the Orange SIM).
Ok, but why do I need this VoLTE and VoWifi so bad? Because I bought a Samsung Watch LTE, whose LTE option won't work if my carrier disables the VoLTE option!
=> I configure the Watch on my crappy Samsung phone, in which I've inserted the Orange SIM, and everythings works fine.
=> I put the Orange SIM in my OP7T and the Watch's LTE keeps working some hours (also the VoLTE sign is ON for SIM 1 & 2)
=> When the VoLTE sign disappears on my OP7T, for SIM 1, the Watch's LTE stops working too.
That turns me crazy... and Orange is the only carrier to provide a LTE option for my Watch so... I'm stuck. Of course, I don't want to buy another phone, this one is new
So, any way to fake my device for my carrier? Please...
Thank you!
Edit: my thread has been moved to the OP7T forum, but it does not belong here at all. That's a general Android phone question about chaing the model presented to the carrier. So I guess I'm not going to get any answer here...
nice

volte and wifi calling only work for the sim you have as primary data. just making sure that's not your issue

Hi, thank you for the answer, however both work for both SIMs on my mobile. Also I can have LTE activated on obth SIMs at the same time, and for example keep the LTE data on on SIM2 while having a phone call on SIM1.
My issue is absolutely the one I described, which is that my carrier disable VOLTE when it recognize my mobile as being "incompatible" (so they say)
Something like this?

Hello! I realize it's been quite some time since you posted this originally. Did you ever find a solution? I have a similar need for this
Following. I have the exact same problem. Don't have network at home and my carrier doesn't allow wifi calling for my device.
Same here . Trying to find a way around it ...
