I bought an unlocked 10+ for google Fi, the variant I got was Charter Spectrums (blindly). Google Fi services work! However carrier information says Spectrum, I cannot manually select operators (for overseas use) and simcard apps do not show actual roaming network or sim carrier info...always overlaying Spectrum as default even though im on Fi connected to Telekom.
Is there a way to fix this? I need to see real carriers I am roaming on overseas and be able to manually switch when needed its unlocked asides from this seemingly.. I used package disabler on the spectrum configuration services app along with vzwconfigs just incase no dice.
Couldn't you just flash the unlock firmware with Odin?

I have a SM-G955U that's GSM unlocked. It was originally an Xfinity phone, but I'm now using it on mertopcs. Mero supports active data while talking on the phone. But my S8+ disables my data while making a call. I do not have root, is there a way to keep my data while talking on the phone?
Try this settings/ connections/ mobile networks/ VoLTE Calls. I think that's the option you're looking for
That option doesn't appear when I go there...
I've checked through the phone app and the settings menu, nothing like that appears anywhere.

I think this option depends on the carrier itself you're using some carriers doesn't support vollte so this option will not be enabled by default. My carrier supports vollte.
Next to 4G or LTE icon vollte will appear like the picture below

The original carrier for this phone did not support vol LTE by the carrier I'm using now does support it. It was originally Xfinity and now I'm with MetroPCS.

Maybe flash the MetroPCS firmware or unlocked firmware.
You don't need use VoLTE to talk and browse at the same time, if your carrier doesn't support VoLTE your cell phone will perform a CS Fall Back to UMTS and then (if your carrier support MULTI RAB) your cell phone will make MULTI RAB, one RAB CS to voice and one RAB PS to data. The problem is when you are using 2 sim cards, if you make a call from one sim card and the data came from the other sim card, the Galaxy S8+ will block the other sim card in a call.
So to call and use data at the same time you will need VoLTE in LTE or Multi RAB in UMTS but must be the same sim card.
Found out the guy lied. So the US unlocked N20U does work with VZW wifi calling.
It definitely does work with my N20U on Verizon.
The only differences between the Unlocked and VZW version are:
1. Native Verizon video calling doesn't work on unlocked, but the integrated Duo video calling is better anyways.
2. Verizon's model doesn't have the Samsung "Smart Call" feature for Caller ID. Instead, it uses Verizon's app.
3. Verizon's version has the Verizon bootscreen and a ton of bloatware, especially games, news apps, and what not. Fortunately, most can be uninstalled, and the rest can be disabled using ADB.

I can confirm all of the above. I have an unlocked phone, on U1 firmware, with a Verizon SIM. Wifi calling works. There is no "Advanced Calling" menu in Connection Settings, but there's a toggle for VoLTE and it was switched on by default. No 4G icon, but rather a LTE+ icon is shown in status bar. The only thing I haven't found a workaround for is the native video calling. I cannot initiate it (phone app does not show the option when I'm on a call with another Verizon phone) and if another Verizon phone attempts to initiate a native video call, it tells them that I cannot accept video calls. I checked my VZW account settings on a PC, and despite the video call option being on and not blocked, native calling doesn't work, as described above. Duo works fine for video. I was able to get Visual Voicemail by installing the app that I go from another thread. I installed it before checking to see if the U1 firmware added it by default, so I can't say for sure that it wasn't there already.

So I had an interesting observation. I flashed my Verizon Note 10+ to U1 firmware and noticed a drastic reduction in data speeds. After getting the Note 20 Ultra, I noticed the data speeds were nearly doubled. I then disabled a ton of Verizon and Samsung apps, and my data speeds dropped drastically as well. Through the process of elimination, I found that the "My Verizon Services" app seems to have a major impact on data speeds. As long as I keep that enabled on the Verizon firmware, data speeds are blazing fast.
Is it possible that Verizon uses apps to prioritize or de-prioritize data speeds? I'd be curious if one could do a side by side of the Unlocked vs Verizon firmware.

Thanks for sharing your observations regarding wifi calling. How can one tell it is working? I am used to older phones advising that wifi calling was in use via text in the phone app. I'm not seeing this notification on my new unlocked T-Mobile-branded N20U with Verizon SIM.
I also noticed the VoLTE toggle in the phone app, switched on and greyed-out, can't be deselected. Of course they don't want to support anything but VoIP anymore. What is the behavior, if the cell signal is decent it won't use wifi? It can't be forced to prefer wifi, can it? I used the trick of putting it in airplane mode, then turn on wifi to try and force it to wifi call. It said it couldn't make the call in airplane mode, which is not encouraging regarding wifi calling being functional on this phone/provider combo.

From what I've found, if you put another carrier's SIM in a truly unlocked carrier branded phone, it should prompt you to apply your carrier settings upon boot. For example when I put a Spectrum SIM in a Verizon phone, it "converted" the CSC (Carrier settings and boot logo) to Spectrum.
My recommendation is to attempt to get the SIM to switch the CSC automatically. If not, use the patched ODIN to flash the Unlocked U1 firmware, and optionally you can flash Verizon from there if Verizon's Video Calling is a must.

Thanks for the detailed response. I was a little concerned about the T-Mobile branding, and what that truly meant at the software level. I installed the Verizon SIM to this factory-reset phone. If it was going to switch CSC I think it would have happened then. It went through the usual setup steps, but still displays T-Mobile screen at boot. I'm not sure what else I would do to "get the SIM to switch the CSC automatically".
Would you agree with my conclusion that wifi calling isn't working based on the outgoing call failure when in airplane mode with wifi on?
If there is better, more-unlocked firmware I'm not opposed to flashing it. It's been a while since I've played with rooting and custom ROMS, but I'm guessing stock firmware is a lower-risk activity on an expensive phone.
I'll refer to this link to try and flash to unlocked U1 firmware, hopefully that will allow wifi calling compatibility:
OTA and Non-OTA Firmware for N986U and N986U1
Hello, so recently I just got a S21 ultra unlocked (sm-g998u1) and been having some problems. I currently have verizion and the problem being is that unlocked samsung phones cannot connect to verizons 5g network out of the box yet (to my knowledge). Prior with my previous phone (s20+ 5g unlocked), I used the *#*#27663368378#*#* access mode code though "phone by google" to manually turn on the 5g bands to be recieved (plus dss), which it worked.
With my new phone, it seems that none of these codes work, being the one above and the *#272* imei code to change carrier config. When I put the codes in, they just erase themselves. Was the access codes changed on the new android 11 platform? Or maybe im missing something? The s21 ultra states it is in a 5g connection by the notification bar status, but speedtest by ookla states its a lte connection, so just a placeholder. Also, it seems that none of the 4g switcher apps worth either, which I would have to guess are also tied into the access codes.
I have a SM-N985F Note20Ultra, i recenty purchased a GoogleFi subscription and set it up using eSIM, (shows up as eSIM1 on the phone) my phone already has a normal SIM (SIM1) from my standard carrier.
Under Settings|Connections|SIM Card manager i set Mobile Data to SIM1 , after a while or after a phone reboot, it resets to eSIM1, this is driving me mad as i don't want to use GoogleFI for data. Any idea what's going on or how to fix it, short of disabling the eSIM ?

Maybe you can change settings in Google Fi app.
Check Google support:
Activate your Google Fi service - Android - Google Fi Wireless Help
Important: You must activate and use Google Fi in the United States (territories not included). After that, you can use Google Fi service internationally. We grant exceptions to military and State Dep

I have LG velvet 4g dual sim LM-G910EMW, is there any way to enable volte for use on t-mobile?
im having the same problem with my carrier (simple mobile). they are saying my LG Velvet 5g is not compatible with their network upgrade to VOLTE. The specs for my model, do indeed show that it is compatible. They keep trying to get me to "upgrade" to a new phone. Whats going on here?
So I followed the below directions from reddit and it worked great and I now have Volte, however phone still drops to 3g when it makes a call any thoughts on how to fix that?
There is a way to force enable VoLTE on the "LG Velvet 4G Dual Sim" specifically your version which is the "LM-G910EMW".
By default the feature is disabled on this model variant for who knows why.
Follow the steps below: 1. Click on the "Phone" app and dial "##4636##" -If done correctly it'll automatically bring you to the "testing" settings menu.
Click on "Phone Information" -you should see a list of VoLTE settings however by default they are disabled and greyed out but don't worry there's a way to reactivate VoLTE. (You Will Come Back to this Menu later)
Go to your file app and create a file named "enable_ue" -thats all you need to do just create the file, nothing more nothing less.
Go back to the "Phone" App and dial "#*462633*#910#" -This code is specific to the variant and will not work on other non LM-G910EMW Phones. Dialing this should bring up the "Hidden LG Menu"
Select Field Test>Universal Enabler>Create New Config -a menu with check boxes for VoLTE options appearing
Select the boxes as follows "VoLTE" "ViLTE" "VoWifi" "ViWifi" And finally hit "Confirm" -a prompt will appear stating "Vo Services Updated"
Immediately restart your phone to allow the settings to kick in
After your phone has restarted go into your Settings>Network & Internet>Mobile Networks -If done correctly the VoLTE option will now be unlocked and available.
Switch on the "VoLTE"
Now to double check that your phone now truly has VoLTE enabled, repeat steps 1-2. If done correctly the menu should now say "VoLTE Provisioned Video Calling Provisioned Wifi Calling Provisioned " -if these 3 are all switched on then you have successfully force enabled VoLTE on your LG Velvet 4G Dual Sim LM-G910EMW, congratulations!
Sorry I'm not so good, can you help me please regarding this:
Go to your file app and create a file named "enable_ue" -thats all you need to do just create the file, nothing more nothing less.
I would like to know how to create this file, as I think I didn't do the job so I'm block when I enter Unviersal Enabler, it say: not supported
Thanks in advance for your help
In the upper right of your file manager there should ne three dots, click on that and it will show new folder, new file, etc.
Some file managers do not have a new file option so you may have to download a different file manager. I used 3c as my file manager.
Hi,
Can you please share the path where we need to add the file name as "enable_ue" and it will be 0 byte file right?
I just added it to the main storage and yes it was 0 byte
Will this work on the 900TM variant? I used 900 instead of 910 to get the hidden menu and it came up but i can't seem to get the volte button to enable in the menus.
If you have one variant of a Qualcomm LG Velvet can you turn on VOLTE by selecting the stock firmware for a different Velvet variant? Basically I wondere if an lmg900tm can be turned into an lmg900um. [NOTE: upon further investigation, the VOLTE feature may depend more on the SIM card and not on the firmware. There is an explanation here from Quora.com:
Is VoLTE activation dependent on the SIM card or just on the device model and the operator?
The phone has to be VoLTE compatible, that is the hardware itself must be able to handle VoLTE in terms of what it implies: band, frequencies and so on.
Then, the phone has to be provisioned to operate with VoLTE, in simple terms that means that the phone must be enabled or allowed to work with VoLTE, this is done wither by the manufacturer or by the operator. There are phones that even while they are VoLTE capable, the manufacturer of the operator won’t provision them to use VoLTE. One such case are the Google Pixel phones that are perfectly capable of VoLTE. but, if you insert a SIM card of a country where Pixels are not officially sold and supported, then Google has the phone set to disable VoLTE (and 5G as well).
Then, the SIM used in that VoLTE capable phone and VoLTE provisioned phone has to be of the right version. Some operators won’t provide VoLTE service if you don’t have a SIM with a minimum version (and thus SIM firmware and configuration).
Lastly, you have to be physically present on the network that has VoLTE capabilities. You could have all of the above, but, if you are in the middle of a desert or in the middle of the Atlantic Ocean, probably VoLTE is not going to work…and neither 4G or 5G…
Is VoLTE activation dependent on the SIM card or just on the device model and the operator?
Answer: VoLTE activation is controlled by the device depending on the SIM and network operator. Of course the phone has to be VoLTE capable in the first place. Each device has an internal database that uses one or more of the SIM files as key to retrieve various parameters about the operator own...

There you have it, that is pretty much in simple terms, what is needed to enjoy VoLTE with your smartphone.
