Is it possible to get a unlocked s20 and install a Cricket wireless rom on it?
If the device supports the LTE/5G band's that cricket uses then yes, you will have no issues putting a cricket sim in it.
What I meant was could I put the cricket wireless software on a unlocked s20. They claim it has to be the cricket branded s20 to be able to use wifi calling.

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.
Good evening all,
I recently purchased an unlocked snapdragon S20 Ultra 5G and I am unable to get the Network Mode option under Mobile Network. Is there any way I can enable without having to wipe the phone?
I am currently on AT&T and in the LA area where 5G is available (I checked on the map)
Thank you!

Are you currently on ATE4?
In order for me to have wifi calling and 5G I had be running ATE6 U CSC from G988US.
Go to this thread https://forum.xda-developers.com/galaxy-s20/how-to/g988u-g988u1-firmware-links-flashing-t4054133

Thank you for your reply!
I went ahead and followed the tutorial again and no success..
I am getting 5Ge which is not true 5G just a little gimmick AT&T has pulled. Notice in the screen shot how it says LTE still.
And I still don't have the option to select the network mode.. Which leads me to believe that that is what is blocking 5G from happening.
I'm currently in the Modesto area which according to the AT&T website should be one of the few cities to have it here in California..
I'm beginning to think this Snapdragon version I purchased has the band locked for some reason...
I have found out why I wasn't receiving 5G, my AT&T plan had to be set up with AT&T Elite or AT&T Extra plan. Without that I wasn't able to access the 5G network. It's a little mind-boggling that we have to pay extra to access 5G.

Paying extra for 5G is pretty standard. Besides having faster download speeds, what advantage(s) do you have over 4G, receiving a text or email 3 seconds sooner? I'm holding off until networks are built out and Service Provider standards are defined. In the future when more 5G utilities are widely available it makes perfect sense but for now I can't justify spending more for a 5G Device and additional Service Provider fees.
I'm considering the dual sim intl s20. Anyone know if the Samsung firmware (unbranded) has the ability to use wifi calling (att or tmo usa specifically on sim1).

I have the 9810 model running both Google Fi and ATT.
WiFi and HD voice works for Google Fi not for ATT.
I purchased this model of phone through Best Buys online retailer. They misadvertised the phone model and sent me this SM-N976V.
The phone seems to work fine aside from the fact that it doesn't show the 5G network here. I confirmed with Telus that their network is operational.
Does anyone know why it isn't working with this phone or if there's some sort of workaround?
I Googled that model. It came up Verizon. It also came up that a ton of people had issues with it and the 5G network. Something about that phone came out in 2019 and it isn't compatible with the new 5G network. You might want to talk to tech support.

That's the problem, it's a Verizon model. The phone was advertised as just a SM-N976 and they just sent me this Verizon model instead.
I am wondering if there's some way to remove the Verizon software to make it just a plain universal model.

I have yet to find anything to open a Verizon phone to make it universal. Verizon is on the CDMA network and say AT&T is on the GSM network. So I don't know if it's in the phone or sim card that makes the phone universal.

Look into changing the CSC to GCF instead of VZW and (for my n976v with one ui 3.1 &hiddenmenu) it took all of verizons bloat off apon sim change.
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.
