Does anyone know how the new unlocked devices handle carriers like ATT for calling features, like WiFi Calling? The Pixel works as long as your account is activated for WFC
If not, will you be able to flash carrier former on an unlocked device to get features working?
I don't know how that works with ATT - I know that my G975F does not get those calling features - but considering the unlocked Pixel Does get Wifi Calling and and Enhanced LTE on ATT, it is possible that an Unlocked Samsung Phone will too. (if it were a tmobile phone, it would not get WIfi Calling on ATT - but I honestly think the Unlocked Samsung Might) Good Luck.

Wasn't sure ..... It was strange in that ordering the unlocked from Samsung have 600 credit for a Note 9 , but only 300 for an ATT ???
I have accounts with ATT and TMO ..... So I thought I know unlocked might be best
But I don't want to end up with no calling features on either
Worst case i would assume you could Odin the att files on the unlocked version to enable it. That's how it's been the last few years anyway with Samsung devices(snapdragons). I know that those features work on the unlocked with t mobile.
On T-Mobile I get WiFi calling and volte with my old Note 9 and current S10+. Never had an issue. The only thing you do t get is that aggregate LTE capability. But I don't really notice a difference in speeds. Not sure how it works with ATT.

I can tell you that the Unlocked S10+ does NOT get WiFi Calling or VoLTE on AT&T.
S10+ here on T-Mobile all is solid with unlocked.. I expect the same on N10+

Did you try any of the "tricks"? Like Odin flashing carrier firmware or making sure that ATT had your IMEI in their database or even putting an ATT device IMEI in your account settings?
Because if you do nothing and expect WiFi calling on a non ATT device it will never work
I have the unlocked Note 10+ on T-Mobile and have all of my carrier features except native video calling/rcs.

Odin flash carrier firmware. I'd rather just buy the AT&T version and not have to go through the trouble.
Yes, AT&T has my IMEI in their database. I even gave them one from my AT&T branded S9+, but that trick doesn't work anymore. They read the IMEI directly out of the device at some point when it connects to their network.
I called support and asked them to verify that I had WiFi calling and VoLTE provisioned, but then when they saw the IMEI was from an unlocked S10+, they told me it wasn't supported.
I did everything I could short of flashing the carrier firmware, which I didn't want to do because I was considering switching back to Verizon. BTW, WiFi calling and VoLTE works fine on Verizon with an unlocked Samsung S9 or S10 without having to flash anything! It's AT&T that's being difficult.
What Guyd said. I called At&t to see if they coould provision a device. The young lady I spoke with gave a list of like 5 devices they can provision. I then asked about the unlocked firmware and they do not support unlocked firmware for advanced messaging..wifi calling..or volte

For sure, with some of my prior devices unlocked firmware or even custom ROMs would not allow for ATT to be successful with WFC. It takes an IMEI ,(that's from an ATT branded device that does WiFi calling in your billing account) ..... AND ..... The correct CSC stuff ...... AND ...... a couple of files that are used by the system with ATT WFC.
The Pixel 3 and Pixel 3a had all that was needed, even though unlocked, to work with ATT and obtain WFC as long as you had correct info on ATTs end with an IMEI that allowed for WFC on their Network.
Btw in my experience I never had any issues with another IMEI being maintained in my billing account but admittedly it was easier for me to change IMEI because I could do it myself with my business account portal.
But some prior devices like the Note 9 and S9 and 10 required other stuff including files to make things to work.
My original question was a hopeful one that the newer device Note 10 (unlocked) possibly had everything it needed ( at least on the phone's end to make things work, like the Pixels do).
Btw. In my experience, asking level 1 or even 2 ATT tech support is utterly useless with things like this.
They don't " support" anything that isn't in their cookbooks that they read from during a tech support call!!!!!
All that said, my guess is that we may have to flash carrier firmware with Odin to get calling features with ATT but I also guess that TMobile will work out of the box, as I believe some have confirmed already

Has there ever been an attempt to sue AT&T since they force you to buy from them...and disable phone's features that you pay for but can't use due to having an unlocked phone?

No
1. They DON'T force you to buy from them. You can buy just about any unlocked device and use it on ATT. For example the Google Pixel or any of the Samsung Galaxy phones.
2. They haven't disabled anything on your phone. But they have a right to determine which phone features will work on their Network. Unless you are paying a separate fee for WiFi calling or VoLTE, then they aren't disabling anything that your paying for. They simply require you to use an ATT branded device to access certain free features.
Does it suck that you have to have an ATT branded device? Sure. Is it illegal. Absolutely not.
By the way, ALL the carriers do this to an extent. Sprint won't hardly activate a phone on their Network that isn't a Sprint branded device. I think they've eased those restrictions, but just a couple years ago with the Note 8, they had a very strict list of BYOD devices.
WiFi calling and VoLTE works on T-Mobile with an unlocked device, but RCA messaging and video calling from the stock dialer does not.
I'm not sure about Verizon, but I believe not all of their features work with the unbranded firmware either.
I flashed my unlocked Note 10 Plus to the ATT U firmware. I am using ATT prepaid. Right now ATT wifi calling doesn't work with Note 10 Plus but it does work for S10 Plus (and previous models). I am pretty sure this is because the Note 10 is still very new and their system needs some update. I will wait a couple weeks and see what happens.

I am 99.9% positive this will not work. Every Nexus 6 sold was identical in terms of carrier compatibility, the only difference between devices was color and storage capacity, same thing for the most part with iPhones. Samsung has historically never done one model for all carriers, instead they choose to make each version specific to that carriers frequencies/technology. The Tmobile S6 would only ever connect to Verizons Band 4/2/5 LTE in a perfect situation but most likely it will just reject the sim all together. A Tmobile S6 will work on ATT when unlocked since they share a significant amount of frequencies and are both GSM and vice versa. If you want a phone that works on Verizon and Tmobile 100% your only 2 options are the Nexus 6 and the iPhone.

Here is what I've found out. I am in NYC, so the radio bands availability may differ depending on your location. I was able to receive a stable 20mhz bandwidth band 4 LTE data service. Text messaging works perfectly fine, but the call doesn't. When I made a call, the phone dropped the signal completely (the signal came back on when I pressed "end call" button).
You can by an unlocked S6 on Mobicity. They said it will work on Verizon...don't believe them! I called and chatted with Verizon and they said that they do NOT allow other phones on their network...period. You can use their Verizon branded phones on other networks such as AT&T or T-Mobile, but not the other way around.

i spoke to a vzw rep and it is possible. the catch is it must be an unlocked phone. if it belong to a carrier vzw will not activate it. this sort of explains why the LTE data was working but the voice wasn't. I wonder if I can get an international version and activate it on vzw now.
I don't think the TMO variant has the right CDMA bands to operate properly on VZW. That would explain why you had LTE data but no voice as voice calls would be routed over CDMA. I'm honestly surprised you got the device running on VZW at all as it is SIM locked to T-Mobile.
No VoLTE Yet....

Because the S6 and S6 Edge do not ship with VoLTE out of the box (later update at some point)... this means the Verizon variant will need the CDMA radio's in order to do voice calls for now.... however once the VoLTE update for the phone (whether by T-Mobile OTA or Samsung OTA Update) then you should be able to successfully place calls on Verizon via the T-Mobile phone since it utilizes the LTE radios to send voice as data... so the short answer is no it won't work on verizon unless you install something like hangouts and make wifi calls/ data calls with the Verizon SIM in or maybe even Google Voice to place calls... might be worth a try using your buddy's SIM in your phone :good:

VoLTE is enabled out of the box however VZW won't provision the device for these services as it is an unrecognized device. You might be able to force it on with the web portal but no promises. That's how it's done with the nexus. If it doesn't work that way it won't work at all as the fallback CDMA won't be available to the device. Consequently you'll be prone to dropping calls as the device won't be able to transition to CDMA in low coverage areas even if you can get VoLTE up and running.
If you don't believe me that VoLTE is enabled:

Verizon reps have heads up their behinds.... basically you need to get someone that understands what you are wanting to do instead of reading the "flip book" answers that they have "canned" for not-so-intelligent reps. that do not take their jobs seriously.
Here is what actual facts with VZW with non-supported VZW devices:
1. VZW Features such as enhanced voicemail, VZW messaging, etc. will not work
2. It is somewhat a "trick" to activate a new SIM card for a non-supported device... because VZW requires a IMEI number for a phone to activate that must match the size of SIM card being activated... for example for a nano-sim it must activate to a nano-sim phone IMEI & not to a micro-sim phone IMEI... VZW has "dummy" IMEI's setup to support non-supported device activation... they just activate the SIM to the "dummy" IMEI for the correct size SIM then once activated, as soon as it is placed into a phone, the IMEI updates to Verizon....
3. It does for most part "lock out" changes to your plan... however, if you don't call into them to have them "look" into something on your account then they will not revoke any discounts....
I have sold a number of non-supported VZW devices to people that are on VZW.... and this is compiled from their experiences and my own... basically nowadays... nanosim is going to in everything until something smaller comes out, so once you have a nanosim that is activated you are set, especially with Verizon.....
I am curious though with whomever placed the Verizon SIM into a TMO phone since the phone's from TMO are suppose to be SIM-Locked....

It's unlocked. I do not wish to have Device Installment Plan where I have to pay certain amount each month. I just paid the total cost of the phone up front, so I don't have to make additional payments. Since I was a T-Mobile subscriber for 7 years and I paid the total cost of the device up front, the customer representative provided me with the Unlock code for the device.

You're lucky if that's what happened. Their policy states they won't unlock the device unless you've had service for a month and a half. Business users are 14 days.
The customer service rep did mention this policy but the rep said that he has the ability to waive the policy under special circumstances: 7 years subscriber, device paid up front, and account in good standing.

For those of you that have the Verizon S9/S9+ .. have you flashed the U1 unlocked firmware? Any bugs?
Do any of you still have the grandfathered unlimited data plan? Wondering if I can get the VZW S9, flash unlocked firmware, and have native hotspot work.
I have successfully flashed U1 and Tmobile Firmware on my g960 (verizon version)
So far, I have not noticed "bugs"
From my understanding U1 is what you get from Samsung Directly. With that said, you wouldnt have any incompatibilities as the barebone hardware is the same in the US variants.
One thing that I dont know though is software updates, if they are pulled OTA or if I have to flash every time.
Advanced Calling works as well as Wifi Calling and visual voicemail.
video calling doesnt work unless you flash a carrier firmware
If you have the grandfathered account with verizon, and you flash the U1 firmware. You can wirelessly hotspot or USB tether "natively"
Thank you for the information! Bummer about video calling, I use that more than visual voicemail.
Definitely sounds like this is the way to go.
Hi there,
I have a verizon phone and I am trying to use the hotspot with my unlimited old fashioned plan. I don't want to root. Unfortunately I brought the Verizon s9 not the Samsung S9 unlocked. Is there a way to bypass the company prompt for the feature and turn the hotspot on yet? I tried the one that works for sprint and it did not work for me with Shortcut Master Lite. Any advice would greatly be appreciated?

yeah you can flash your verizon s9 to the U1 firmware. this will remove that message, but not all things are guaranteed. also its not like youd be able to root your s9 as you got the US variant.
While I have a verizon hotspot plan, I tend to use USB tethering more than the Hotspot(wifi) option.
Checking on my dashboard online, shows that Im constantly within my Hotspot Plan.
I also noticed that on USB tethering, data doesn't count against my Wireless Hotspot plan.

Hi Eastsidebiz
Thank you for your reply. I apologize about not understanding all the lingo. When you say flash is that different than root? If you can flash and not loose your warranty or anything. My question is where do I go to have that done? Or is it something I can do myself? Also what will I loose as far as stock features if any? I appreciate any feedback and really truly thank you.

Flashing the firmware is different from rooting
Flashing the firmware is like installing a new OS on the computer.
Rooting is flashed preboot of the OS, and then executed when the OS is up.
Warranty / Knox by flashing an OEM firmware, this should not trip warranty/knox
rooting a US variant, if you can even do it, will trip your knox, thus tripping warranty.
If you have a US variant, come back to this thread 2 years from now, as i dont think developers are able to do so as of yet.
this thread is very informational if you need to flash your U version to U1.
Which s9 do you have again?
I thought I'd update this thread. I bought the VZW S9 and successfully flashed it to the U1 firmware to get rid of the verizon bloatware. Nice side effect is that the hotspot seems to work.

hey just a FYI.
If you flash another carrier firmware on that s9, you maybe stuck there.

Hi There,
So you are saying if I flash to U1 software I can use my hotspot. That is without being prompted by Verizon to add feature. What have you lost in the software from the U1 Flash compared to Verizon Software. If I do it and it voids the warranty so be it. I just want to see what I would lose before I do anything.

ALSO! have you updated your VZW S9's software from verizon in the last 3 months? If so, flashing a U1 may not work, I think the newest Update from VZW has v2 of the bootloader

I bought the unlocked S9+ directly from Samsung website to use with Verizon. I got advance calling (VoLTE) to work but I don't see any option for WiFi calling/WiFi texting. How did you enable it?

What is your carrier?
I noticed that TMOBILE is the only one that allows all features to work when it comes to unbranded phones.
On my VZW s9, I flashed the U1 firmware. (using Tmobile) Then Wifi Calling was under the SAMSUNG DIALER option not in CONNECTIONS.
Then on my Unlocked S9, Wifi Calling was under the SAMSUNG DIALER settings (on tmobile), on Verizon SIM, this service is not available.
It looks like VZW/ATT both use their firmware to block outside access. Tmo on the other hand, allows you to fully use your Unbranded phone, but such terrible and outdated technology.
*for those who are getting 20Mbps on Tmobile and happy about that... why??!!?!?*

Unfortunately my phone seemed to have the latest firmware out of the box (February security update) so I might be out of luck then.
My carrier right now is Telcel Mexico (and we don't have fancy features like WiFi calling or VoLTE). I'm planning on switching to T-mobile soon.
What's that of the 20Mbps on Tmobile? Should I pick another carrier?

Wait Feb 2018 may still be V1 bootloader....
So what I noticed with Tmobile (im sure this doesnt apply to everyone) is after 1.2 to 2 years. Your phone line is no longer "new" and data speeds are dropped to least prioritization. Newer plans or line activation obviously gets higher prioritization. Mind you, im not a prepaid user. The only way to fully take advantage of TMOBILE is to switch your device or renew your plan every 2 years, which makes sense and average to some.
on the other hand, I have been having Verizon for the past 4 years, and used 3 different phones then (no line modifications, upgrade.. etc) and my prioritization has been constant. and averaging 70Mbps real time, about 7-9 MB/s (i download torrents on my phone) and its always constant (even if i go over 65GBs a month)... just my 2 cents...

Hi There,
So you are saying if I flash to U1 software I can use my hotspot. That is without being prompted by Verizon to add feature. What have you lost in the software from the U1 Flash compared to Verizon Software. If I do it and it voids the warranty so be it. I just want to see what I would lose before I do anything.

Here's my take: I bought bought an S9 U1 direct from Samsung, did a Smart Switch backup of my damaged S7 to my pc, swapped the SIM and SD cards to the new phone, powered it up, did the Smart Switch restore and was good to go in under an hour, hot spot without prompt etc.
Based on this, if you can flash the U1 firmware you should get the results. The kicker to that is the bootloader version. My wife's s9 from Verizon took the August update and is now on build ... S3ARG9 - the 3 indicating v3 of the bootloader. The latest U! firmware available is S2ARF4 - bootloader v2 and you cannot downgrade the bootloader. BUT if you happen to be on the ARF4 or earlier build then go ahead and flash. Samsungs Voicemail app works with Verizon's VVM (basic), Messenge+ also worked, though I switched to Mood so that I can assign specific notification sounds to certain people.
Att to Verizon.
I bought a in Att s9 g960u phone and I want to use it on Verizon. I got a sim unlock code from a 3rd party so it is sim unlocked but I put in a Verizon sim and it doenlsnt connect to verizon. Is this because of the Att phone uses GSM and Verizon uses cdma? How do I get around this

Phone hardware should be the same. Possibly flash the U1 firmware. Or you may have to enter in carrier APN settings - I've never had to do anything like that but I have heard about it before.
Does anybody know if I can use Odin to put stock Sprint A505U firmware into my Verizon A505U? There's no OEM unlock option on the A505U (US version) phone so the bootloader is locked. I prefer not to root so I can use google-pay without any masking shenanigans.
The sprint firmware has a different set of enabled FDD-LTE bands that makes it more useful. Thanks.
Edit:
I've just learned that some carrier unlocked galaxies s8, s9, s10, etc. running pie will auto rebrand and adjust available bands to adapt to whatever Sim is installed. Does the A505U do this? This would be far easier than flashing if it works for the A505U.
The Samsung BYOD rebranding feature for U models based on sim insertion is always released about 10 months after the phone's initial release.
This has been the case for S8, Note 8, S9, and Note 9. It is not even released yet for S10.
So it will probably be getting close to mid-2020 before it is released for A505U, if even then.
Thanks for the response. I am still trying to wrap my head around how Samsung does their "BYOD Experience" rebranding. It appears that Samsung has gone the route of common hardware for US phones while supporting all the major carrier CSC's (multi-CSC?) within a given branded firmware .
Since only the CDMA carriers Xfinity, Sprint, and Verizon have the A505U, I'll try to find somebody with an ATT or TMO sim to see how my supposedly unlocked Verizon A505U reacts. I haven't seen any reports of what happens posted yet as it relates to the A505U.
I have a Galaxy A505U through Sprint. As you've said it is bootloader locked by the carrier. The 7 day trick does not work to show/enable Oem Unlock. I forget the reason now but I have reflashed stock firmware in Odin before which would modify system partion despite a locked bootloader. So I believe that you could in theory flash the sprint firmware in odion but I don't know how this will affect coverage. I do know sprint has roaming agreement in place with vzw so it should work.... But you're coverage may be degraded as I believe it's not going to support all of vzw lte bands... On a slightly separate note I am curious if there's some way to get around the lock using Odin. I am rusty on my Samsung modding(not eisnce sgs4) and terminology but I'm wondering if we could flash just the bootloader itself from another variant.

this is not accurate.. the devices contain multi csc in the omc partition so once the device is sim unlocked all the firmwares for usa variants have the csc for all the carriers.. you can use an app like phoneinfo and see the available csc's.. it has been this way as you stated since the S8 and up...
now if you are talking about U1 devices then thats a different story.. U1 devices typically have the same csc's but are just unbranded meaning little to no carrier bloat for example.
this is typically why all the firmwares are interchangeable because they are all containing the same csc. The only difference sometimes will be the userdata which might b labeled specific to a carrier but ultimately this doesnt matter either as they typically would contain only a few extra carrier bloat apps that shouldnt impact overall function at all..
heck, if you know what ur doing you can even change the csc code without even flashing any other firmware or putting another sim in.. i typically for example use sprint sales code with vzw network code bcuz i have verizon but sprint has more dialer codes..
as an example my g975u was purchased from verizon but i currently set the csc to GCF for research purposes and all my vzw services work great and to start I used a U firmware that had userdata labeled for SPR lol I also removed the last bit in the carrier code for research purposes.. when i toss a tmo sim in it automatically loads the apns and carrier mode for tmo and it just works without even rebooting

you are correct.. the usa variants are multi csc so they should work anywhere.. international devices also contain multi csc for w.e region it is purchased in. once sim unlocked if u say try to take ur phone to china or something ur device wont contain that csc but you should be able to get it to work with apn edits for example and might not have all the bells and whistles since couldnt flash their specific csc if that makes sense..
These phones nowadays are all world capable for the most part and contain the hardware to work on the differet networks (cdma gsm etc)
Samsungs "byod" experience just means its carrier unbranded so its sim unlocked out the box and can b used on any usa network without all the carrier bloat.. this is sort of pointless in my opinion since usually these firmwares can also b flashed to carrier branded variants..
on a side note, i have a tmo sim but mainly i use verizon and am getting an A50 from big red tomorrow so I will test this out for u and let u kno how tmo is in a vzw a50.
i have a tmo purchased a10e and my vzw sim works great in it.. in fact, vzw works better in the tmo phone than tmo haha but thats bcuz tmo isnt as good service wise in my area

Thanks for the great info! Please let us know how the TMO sim works out. I'm most curious about whether TMO features like their VoLTE and VoWIFI are enabled.

Hello..
Your comment sparked my interest.. as I'm a new owner of the Xfinity variant of the Galaxy A50.
Although I have no plans to leave Xfinity for the remainder of 2019.. as I'm waiting for my $250.00 Promo Rebate which comes around the 4th Month of service to cover just under 65% of my investment in the A50... leaving me with a $135.00 balance.. But, if what you state is indeed the case.. and these devices have the guts to run on traditional GSM Carrier's.. this add much more intrigue into the equation..:angel:
I'm not one to pry.. but, did you follow through with your purchase? and if so... what were your findings?

That is correct but as someone who works in the industry and works with 3 out of 4 nationwide carriers I can say Att typically has there iphones manufacturered without a cdma attena making it gsm only.
I just checked my sprint A505U and it does have csc codes for many carriers including att, spt, vzw and t-mob among others. So generally another firmware should work fine then?
I had purchased a used SM a505u from dubai market. 1 YEAR IT WORKS FINE and after that I understand phone is not getting updates and there was issue with fingerprint sensor. And I decided to flah march2020 update from samfrew . But after that I am not getting network .it says networ error. Sim card crash.contact carrier etc...
Will the unlocked S20 Ultra work with Tmobile Wifi calling?
Hi,
Not sure but here's my history:
Bought an unlocked S9Plus from Samsung, had issues with WiFi calling on tmobile, never got it working.
So when S10 Plus came out I bought the Tmobile version from Samsung, everything works great.
So I just ordered the s20Plus from Samsung but the Tmobile version to make sure all is well with WiFi
and Tmobile's 5G systems. After a month or so I call Tmobile and get it unlocked, so no problem there.
Just safer to get all the Tmobile crap on there to be safe, also no issues with voicemail to text app either.

WIFI calling may not work I've been told. I just ordered a S20 + unlocked that I plan to use on Verizon. I would have gotten the carrier specific except I am buying it out right and would only get $300 trade in on my S10+ unless I used Verizon financing.
I refuse to do that so I went with the unlocked and got my $600 trade in. If I have bad problems I can always send it back and get the branded one.
My concern wasn't WIFI calling or VoLTE I had to make sure Mobile hotspot and MMS will work and I have been told they will.
I don't use the other features, so they don't matter to me.
So I have the unlocked S10 I use on TMobile work's beautiful and the s20 should as well I can even use wifi calling like you questioned which I hope carries over as well but I'm assuming it should I'll know in about 4-5 days
yeah every unlocked phone I have used on Tmobile wifi Volte has always worked, that`s why I stick with Tmobile, ATT sucked for unlocked phones....... except for the pixels, anything else wifi calling and VOLTE would`nt work.
As soon as I put my t-mobile sim in my U1 it re-starts and installs wifi calling feature. Just confirming it does work

Wi-Fi calling usually works on the unlocked Samsung phones, it's the in-dialer video calling that doesn't. Also, T-Mobile's implementation of RCS in the messages app doesn't work with the unlocked phones. It's usually very easy to flash the T-Mobile firmware using Odin on the unlocked model. That way you get all the carrier specific features. Make sure to boot your phone on the unlocked firmware (with the TMO SIM inserted) before you flash over to the carrier specific firmware. It's known to cause issues if you don't.

Do you know if the same thing works for Verizon? In other words, can an unlocked Galaxy S20 be flashed with Verizon firmware in order to enjoy any Verizon specific features, but still enjoy being bootloader unlocked and rooted?

You can't be bootloader unlocked and rooted since Samsung does not allow you to unlock the bootloader in the US for any carrier. If you're referring to Exynos phones, you can't flash those with the US (unlocked or carrier) firmware. For US phones, you can only flash the US unlocked to any of the US carrier firmware or the carrier phones to the US unlocked firmware.
You can find the firmware here: https://forum.xda-developers.com/ga...g986u-g986u1-firmware-links-flashing-t4054629

I heard about this was thinking if I could flash T-Mobile on the unlocked version will it remain unlocked? Or should I just use Google messages RCS

It's a very easy process and it will not "lock" your phone. You can flash back and forth with no issues.
T-Mobile RCS shows users who are on with a blue dot next to the contact name. It is also different than the Google RCS. If you want to use Google RCS, then everyone you message also needs to use Google Messages in order to take advantage of it. It's up to you if you choose to do it, but if you use T-Mobile and your friends and family do too, it might be worth it.
EDIT: Also if your phone is carrier SIM locked, flashing an unlocked firmware will not unlock it for use on other carriers.
I purchased a Verizon Galaxy Note 10+ 5g from ebay last year to use for Total Wireless. Well the phone wasnt compatible with Total Wireless at the time and I had to switch to Verizon prepaid. Now the phone is compatible but I cant add APN's to the device because Verizon has greyed out the option. I bought a US Mobile Sim card so I can switch all of our phones over since it is cheaper and is a Verizon MVNO, but I cant get everything to work on my note 10+ 5g. I was able to download an app that let me add APN's and the LTE comes up but now I cant get VoLTE to work. Its turned on but when I make a phone call, it switches to 1x. This is a problem since Verizon is doing away with their CDMA Network. I have spoken to Verizon, US Mobile, and Samsung with no help. My other Note 8 will work just fine when I put the US Mobile Sim card in and my Samsung a71 5g wont work at all and wont let me add APN's even with the app.
I have been doing research and found out about SamKEY and bought some credits to change the CSC from VZW to XAA. I was in the process and it gave a warning about locking the SEC so I decided to do more research before I screwed something up.
The phone is unlocked but for some reason, Verizon phones have these issues with a Verizon MVNO. I can add the TMO sim card from US Mobile and it will allow me to edit the APN's without an issue but I get zero coverage here so I cant use it. So how can I change the CSC to get VoLTE working on a Verizon MVNO? Or can I even change the CSC on this phone? I am so sick of Verizon phones but Im afraid to buy an unlocked phone since It doesnt support all of Verizon's bands.

IDK about unlocking an US device. I prefer unlocked devices.
US unlocked versions of Samsung devices are called "U1". It's part of the model number/name.
E.g. SM-G981U is the US locked Samsung Galaxy S20 5g (like for Verizon), and the SM-G981U1 is the US unlocked version of the same device.

Thanks for the reply. I ended up selling the phone and buying a Google Pixel 4 XL. Saved some money and its unlocked. Ill never buy another Verizon Edition of the phone again.
