Fake phone device model to network carrier - OnePlus 7T Questions & Answers

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...

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?

There's an xposed module which looks like it does what you want

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 ...

VoLTE on AT&T

Does this work? Does anyone know how to enable it?
Great thread. I wonder if we can enable it because it does not work with any custom roms
It's been confirmed working on the pure nexus ROM. Check the development thread
It has not been confirmed working on att. I follow that thread closely. It's is working on Verizon and Tmobile.
I am running pure nexus with att and no volte

My apologies. I must've read it wrong then
Stu, do you have a VoLTE enabled SIM in your 5X? You have to have an account in the HSS and TAS to get an IMS registration...
I really don't know. Is volte working for you on att and the nexus 5? I don't think it can work but I hope I am wrong
Did you just pull the SIM from an existing phone? If so, was it a VoLTE phone? AT&T will only provision the SIM/Account for VoLTE if you have an approved device.
And no, I have not gotten my 5X to do VoLTE yet....working on it.
My friend just got Nexus 6P + new AT&T sim card. We made couple of calls and there is no VoLTE option in the cellular settings, as I have with my 5X on T-Mobile.
Remember that any VoLTE network is *completely* different than the existing CDMA/GSM/UMTS networks that the providers have. VoLTE utilizes an IMS or USP core that the phone has to register on to get VoLTE calls to work. The SIM information has to be defined within this IMS core, otherwise you will only get legacy services.
AT&T will currently only define a SIM for VoLTE is you have a certified device that they sell. But I already have VoLTE phones and am trying to use their SIMs without success. I think the 5X software may not be allowing the IMS registration. If you are on T-Mob I would call them up and see if they will provision your SIM for IMS....they don't seem to care about what phone you use.

How does pixel family manage VoLTE and VoWIFI?

Hi Guys,
Have a P3XL and it works with VoLTE fine with my main carrier - Vodafone Australia.
However, in the coming 12 months, I will be working extensively throughout the Asia Pacific.
I know previously with some Android OEMs, it was basically baked in for that phone/carrier combo, and even if your phone and network potentially supported the service, if you were on the wrong region firmware, you were SOL.
How does the pixel family manage this? Would it detect the sim card that I have and automatically configure the VoLTE if it were supported by that carrier? I know recently, via a tweet from @LlabTooFeR that some people are modifying to gain this, but dont want to resort to this if I dont need to. (Phone is rooted already though haha).

EVR-L29 Enable VoLTE

Is it possible to enable VoLTE when it's not enabled by default. I just bought this phone and I don't see the setting.
Thank you
Settings-Cellular Network-Mobile Data.
However, it must be supported by your Provider, otherwise it will not be displayed.
It's not there...that's strange 20 Pro is supported but 20X isn't

It worked on OnePlus 8 which I previously had. So I think sim card is not a problem
I have a Mate 20 with the same issue. VoLTE doesn't works on T-Mobile and is a software issue related to Huawei. Lots of people are having the same issue:
I Just made a post on Huawei Forums for see if we can report the issue. The more the people reports that increases the chances that this can be fixed:
​
https://consumer.huawei.com/en/community/details/topicId_120349/
Anyone get any clarity on this issue? I have AT&T in the United States and my IEMI was targeted for shut off today. After going a few rounds, they turned it back on but told me there was no way to prevent future pre-emptive shut offs because me EVR-L29 does calling over 3G which sends an automatic kill message. Further, as many have described, there is no switch to enable VoLTE in my settings. Are there other larger (7" plus) Chinese phones that are 4G LTE calling? Is there a way to address this issue with the EVR-L29? Thanks.

LG G710ULM UNSUPPORTED VoLTE ?!? (Straight-Talk US - T-Mobile network)

*********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?

Question Realme Gt Master Edition VoWifi dont work?

it depend on your sim card carrier
I have been looking for that information, thinking about getting this phone to use T-Mobile USA GSM voLTE? is this phone compatible?
@ryantek No, it's not. I have been using Gt Master in Mint Mobile (which is T-Mobile MVNO) for 6 month and no VoLTE, no VoWifi. I could use mobile data, but even this was not very good, often gets stuck to 3g network, though GT Master supports most of the LTE bands used by T-Mobile (except for B71 600Mhz).
I had two long chats with Mint Mobile customer service, no resolution.
I believe it's gonna be even harder to activate it after July 1st, when T-Mobile will shutdown it's 3G network. Mint Mobile didn't make me any problems to buy and activate service, but now constantly bugs me to replace phone for compatible with their network.
I've also tried it with US Mobile (T-Mobile network), Boost Mobile (ATT) and couple others. The same effect.
Save yourself some trouble and buy phone that's on compatibility list: Oneplus, iPhone, Samsung or Motorola.
I bought Galaxy S22 and now use it as my main device in Google FI. GT Master still have active Mint Mobile simcard until 3rd of June, but after that it will be over.
Hi,
Thank you for sharing all of this information. It is sad to see the carriers in the USA do not support this phone. Sadly I will stay away until anyone can confirm a phone of this brand that works with VoLTE (Tmobile).
Once again Thank you.

Set up VoLTE and VoWiFi via QPST and the ( advaced pdc tool PDC ) Root is required. This option works in stock. You need to try several "choose" profiles, one will definitely go
In custom rom, if it doesn't work, just back up the EFS partition (after editing in stock rom) and restore it later in custom rom
I see. Wondering is there is a signed ROM with VolLTE enable out of the box.
Today I tried Google Fi simcard with my Realme GT Master (normal not modified ROM) and it worked!! VoLTE is working and so is VoWiFI (I think). I'm not 100% sure about VoWifi. I have icon of VoWifi during call but I can't make call just on WiFi while on Airplane Mode, I have to turn off Airplane Mode or it doesn't allow me to make a call.
Google Fi was activated with Galaxy S22 few months ago.
I'm not gonna test it for long, because I use Galaxy S22 as my main device now and in few days I'll move to US Mobile/Verizon, but Google Fi is usable. I still can't recommend buying GT Master for US: too much hassle, too many unknowns.

so basically you don't know which network you were on while VoLTE started to work? Google FI uses all three networks and switches them dynamically
As far as I know Google Fi uses two networks: Tmobile and Us Cellular. As I'm in western Massachusetts and US Cellular doesn't have coverage here, I'm pretty sure I got connected to T-Mobile. But I can't confirm it with 100% certainty.
