Hello, I recently purchased an S20 ultra. I have 2 questions regarding it if anyone can answer any one of these that would mean a lot to me.
1) What I've noticed is that the phone has Verizon apps installed by default and when I go into download mode it says Carrier = Att. So is it a Verizon carrier phone or Att one?
2)If it is a Verizon phone, How do I know that it's locked? I am currently able to use a non-Verizon sim. I am running Android 12 I haven't updated it to Android 13 is that the reason that the sim is working?
Thanks!
Edit: @Unreal_Hawkz has fixed my issue

Anybody have a S10 series on Verizon answer a couple questions for me?
I would like to confirm if or not bot Mobile Hotspot and MMS message work properly.
and any other quirks and besides the benefits of no belote ware, I'm planning on getting a S20+ but the Verizon version is $300 more than unlocked and I don't need or want Wi-Fi calling.
Thanks in advance
Curious if there is really an advantage to unlocked vs carrier in this case beyond ease of resale?

I've had both an Unlocked S10+ and a Verizon S10 (running Unlocked Firmware) on Verizon. Mobile Hotspot/MMS works on both, along with all other Advanced Features (including Wi-Fi calling/etc).
Thanks that's what I wanted to hear.

Had a similar problem on my S8 with att, flashed the att stock firmware through Odin and volte, and wifi calling worked. I have since changed over to the stock unlocked firmware to send in my phone for trade in and it doesn't work anymore. I order the unlocked 20+ as well do I'm hoping just flashing whatever carrier branded firmware for it works again.
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

Working fine on my S20+
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.
Hello all I have a question for others using the Galaxy s9+ international models in the US. AT&T is telling me that my phone will not be compatible with their network in 2022 once 3G is dropped. My phone is the G965F dual sim model currently rooted, rommed (RRemix), and running Android 10. Is anyone else in the states facing this issue and have any tips for a workaround?
Thanks
I have searched for hours without any luck. I have been with an AT&T MVNO (Unreal mobile) for two years. During the 3g shutdown I was unable to use VOLTE on my S8 (VERIZON FIRMWARE). I found out the only way to use my S8 on UNREAL was to have AT&T firmware. I spent countless hours trying to flash ATT firware onto the Verizon S8, but I was unable to do it by flashing, but I found another way. I put a TMOBILE SIM in my S8 and it automatically loaded the TMOBILE firmware. Once the S8 was booted up I was able to run a USSD code (*#272*IMEI#) through the dialer which allowed me to switch to ATT firmware! Problem solved!!!! But a few months later my S8 was lost and I got a S9 (Verizon Firmware). I tried the same method as I used on the S8, but it doesn't work. When I put a T-mobile sim in the S9 it does not automatically change the firmware like the S8 did. From the Verizon dialer on both the S8 and the S9 it will NOT ALLOW USSD codes. Does anyone know if there is a way to run the USSD code (*#272*IMEI#) on the Verizon S9? Does anyone know why the Verizon S9 doesn't automatically change to T-Mobile after inserting a T-Mobile sim? Are there any other sims I can insert in the S9 to change the Verizon firmware in order to run USSD codes? Flashing my S9 is not an option for me because I must be too stupid. Anyhow thanks for your help!!!!
Seem's you+I have similar problem! I have s9 verizon unlocked,but I am with consumer cellular. They went to 4g recently now no call or recieve call! They gave me new sim, still not working! Told me shorter mobile wavelength from tower's! Last update on this phone was 2018? Won't update normal procedure! Wondering since this is U.S.A version if any way to update to 4 g? I'm fine on micro-soldering but when it come's to tech,a little to old I guess!!Lol Any help appreciated!

In my case I had a Verizon unlocked s9 and it turns out Verizon has bloatware that prevents many MVNO's from using VolTE. After tons of research the only solution I found was using patched ODIN to flash unbranded stock firmware in order to chance my model from a U model to a a U1 model. Now the phone works perfectly. Someone should file a lawsuit against Verizon (and ATT) for circumventing federal law on unlocked phones (technically they are unlocked but you can't use them because of their bloatware). It really is a major scam.
