Question Unlocked samsung s21 ultra ATT, - Samsung Galaxy S21 Ultra

Hello everyone, I have a question, I own a s21 ultra att, wich is unlocked, I can use it with any carrier , even eSim ( here in Mex ) but , when i look forward the IMEI at the ATT unlock service, it appears as: lost or stolen, also i check IMEI in other pages and it is CLEAN, anyone have experience something like that?
Also, in developer options OEM unlock doesnt appear ( currently in android 13 ui 5 ), I have factory reset, and even network reset it, and still have service, it never drops...
Anyone have an Idea if that is ok or not?

[Q] SKT SHV-E160 Admin Code Problem...

Ok I'm wondering if someone could help me out here. I picked up a Korean SKT Galaxy Note today, however the LTE isn't compatible with docomo's network. I did some searching online and found that there is a code you can put into the dialer to access a STK hidden menu, which ultimately let's you alter the phone to accept WCDMA frequencies and such. The code is:
319712358
However the phone then requires a password. I found 774632 as the password but when I put in the sequence, nothing happens.
I bought this phone used for 65,000 yen (about $720) and it is apparently unlocked, as I can use my docomo number without a problem. I desperately want to keep the phone (the store said I could return it) but have no use for it without the data, and thus would be incredibly grateful if someone could help me out...
May be try to use 996412 instead of 774632

Unlocked AT&T Galaxy S5 not working with Metro Pcs

Hey, I'm really new to unlocking phones and this is my first unlocked phone. I unlocked the phone using GSM UNLOCK labs and it unlocked fine, but I'm not able to call, text, or use data. I have already changed the apn settings to metro's but it still doesn't work. Aldo I get a phone not allowed mm#6 when I start up my phone. When I try to call someone it says not registered on network. I don't think it's an imei # problem cause I can still check it and see that's it's the same since before I unlocked it.
Thanks any help is appreciated.

Enable Volte and VOWIFI on unlocked note 8

Hi,
I've an Galaxy Note 8 (canadian, SM-N950W), buyed directly from samsung, so it's factory unlock and not in any carrier database.
My carrier offer Volte and Vowifi on S7, S7 Edge, and iPhone. I've an Volte capable sim card, and the volte component is activated in my account whit my carrier (i've an S7 edge in my carrier database).
Now, i want to get it to work whit my note 8. I've done many search on the web, and found nothing that work. I've try to get a shortcut for the ims settings, but it said "not found any csc feature", and the apps won't open.
After that, i've thinked about many other alternative, but i'm not sure if it will work, that the reason i'm asking before doing anything wrong and brick my phone. I know all the samsung carrier-specific function is on the CSC. I can just root and edit the config file, but i don't want to void my warranty, and get limited to 80% of charge.
So, another thing i'm thinking, is to flash the s7 edge CSC on my note 8, that already have the volte function enabled on it. Will it work, because it's not the same model?
I've tried too opening my firmware (downloaded from the web for my carrier), extract it, but when it's time to access the csc img.ext4 file, i get a "corrupted archive" from winrar, that let me doing anything.
Any ideas? Thank!

My logic says, surely the easiest way would be to
flash your carriers Note 8 stock Rom with Odin
If this is possible. This way you most likely to keep
everything official. (Knox etc)
I was in a similar situation.
In my case i had a branded Note 8 and
unintentionally flashed unbranded Samsung firmware.
I did not also have volte and wifi calling etc.
No shortcuts work
So i flash my correct branded carrier firmware
All was working again.
I have no carrier branded bloat, as i uninstalled
them.
This for me was the easiest option
Good luck.
Thank for replying willcor
In your case, can you access the ims settings shortcut? And then, enable Volte and get it to work?
Are you rooted? And does the note 8 is officialy supported by your carrier?
FInaly, can i just flash the csc whit odin so i will keep my file, or i need to flash the complete rom, and loosing my data?
Thank!

Firstly, i am not rooted. Stock branded carrier firmware.
As i already had my sim enabled for volte, wifi calling
etc with carrier i re flashed the carrier firmware
Volte appeared "automatic" after flashing. (Short while later ) For me the easiest way.
It was unintentionally that i had flash unbranded
Samsung firmware.
I was originally on branded firmware.
(Vodacom /Vodafone.)
I soft bricked my device while
beta testing.
When i was on this unbranded Samsung firmware
i noticed that there was no volte, wifi calling
and no stock Hiya spam software. etc.
I used QuickShortcutMaker to try and enable
shortcut to wifi calling. No luck.
I'm only suggesting you check this option out
... if possible, then surely it the best way to go.?
Further just flashing to change CSC gave me all sorts of
issues.
I landed up having XEF (France) and my device showing 32 gig storage.! Instead of 64 gig.
then flashing again i landed up on XFE (SAMSUNG)
Sorted storage out to 64 gig.
Then again i Flashed carrier firmware
4 x files ( did not flash home CSC but the other CSC
which resetted device and all is well and knox 0 x0
Bottom line is that
all my previous devices are rooted. So i knew what i was doing.
When i soft bricked my device etc.
so i did not panic.
So i suggest make sure or
look for a relevant video etc on YouTube
if not sure
Yes you are going to lose your data. So do a backup.
Flashing the "home CSC" basically is a dirty
flash.. You don't loose anything.
Which i think is not going to help you.?
Good luck.
Hi,
I've flashed the firmware of an operator that support the note 8, but still not any settings for it in the phone app setting. Can't still access ims setting too.

for me the ,the best option /scenario would be .....
1) Your service provider that you enabled volte ,wifi calling etc with .
2) Further your sim requirements ,for me i had to have sim 64 or higher ( with correct CSC of carrier .)
3) Then obviously that same service provider ( above ) stock Note 8 firmware ,if compatible with your Note 8 model /device etc .
According to what i experience surely , above should be enough to get it enabled .?
Plse note.....
i would not use another carrier firmware etc ,
(as in this case) just because it should have similar firmware .
Try to align your options ,to make it easier .!
This for me should be an key option ,not another provider that has similar functions etc .
Remember you got no root ,would prefer to keep knox 0 x 0 etc .
so your options are limited .?
good luck
Hi,
Still not getting it to work. But today, i've noticed LTE+ icon appear intermittent. It's switch to 3G when i place call.
No any settings of VOLTE.
Can't find any solution to root my phone (snapdragon), because i've the new update. I'm pretty sure it's a way to get it to work, but don't know how. It's just software issues because my operator was activated it in my account.
Hi,
Finaly, after 3 !!! factory reset, gessing whit 3 different carrier, i've activated it, i've it in the settings.
Now, when i make a call, it switch to 4G. I think it's the APN. I know my carrier need 3 apn for the VOLTE, and still have only one. I will try to find the 3 apn setting today.
For the vowifi, i see it in the notification center, a toggle to activate it, but it's do nothing.
I've successfully found the ims, there are 4 for my operator. But i can't find the IMS APN type in the option given in the phone.... How i can enable it?

If you want it to be easier call your carrier and have them add the imei # to their database then the imei will be whitelist and reprovisioned...then you can just use the unlocked firmware or the full carrier Firmware...

Try this video. I literally JUST did this after WEEKS of looking for an answer.

I have posted many times with the same info...Several others have as well..
Thanks for sharing though...just search IMS BlueFox721 in XDA search and you will get more info than the video explains as there are other settings to do as well..
Thanks again for sharing
that video and related info is only to add the missing features if you are not on the right csc.
but it wont fix the issue where the carrier is only allowing imei from phones they sell to use these enhanced voice features. In the case of Rogers and others, you can try calling them all you want but in the end they wont do squat to white list your imei. maybe some other providers will yeild to your requests but Rogers is know to not white list non carrier phones.
I successfully got HD Voice turned on and working. But no sign of Wi-Fi calling. I was searching through shortcutmaster and came across a menu where I can turn on wifi calling. It isnt grayed out, however it wont actually toggle over. The screenshot posted is from tapping the menu dots in the top right part of the screen. I assume I need these filled in to enable it. Any ideas on how to populate the right info. Im on verizon, but got the Note 8 from Samsung, carrier unlocked. SM-N950U1

How you turn on Volt?

Emergency calls only

Trying to get my Note 8 working on Total wireless. It's supposedly and unlocked phone, but it does have AT&T boot screen. I activated my service, but now it will not work at all. When I try to call, it says "emegency calls only". Does anyone have any idea why it might be doing this? I'm attempting a factory reset right now, in hopes of that working.
Do you have baseband & IMEI? Is knox tripped / rooted? If so, do you have EFS backup?
You may need to contact your carrier, perhaps some sort of activation in the network is needed
Bought second hand? Check with ATT, whether phone is actually unlocked.
I agree, sounds like you bought second hand. If you bought a brand new unlocked model you would not have any carrier boot screen.
You'd have to check if it actually is sim unlocked & if it is it could be as simple as wrong AP settings.

Question Samsung Galaxy S21 Ultra won't work on Visible or Verizon

Hello, I'm having an issue getting my Visible service working on my Galaxy S21 Ultra SM-G998U1.
I purchased the phone on Swappa to replace my OP7 Pro, so I'm not sure exactly what carrier or model its from. But it should be factory unlocked and I can't call, text, or get data.
I tried installing a Verizon sim but still no service. T-Mobile sim works perfectly though. And I've tried all the troubleshooting steps like network reset, adding APNs, even factory reset.
When I boot the phone or cycle airplane mode, occasionally 5G will turn on for a few seconds and immediately disconnect again.
The APNs all install automatically when I put the SIM in but i just don't get any service, even though it's showing full bars.
go to your sim settings and deactivate it then reactivate it. What version of android are you running? is it rooted? Need more info on your phone. You're sure it's U1 and not an exynos model?

I have done that many times. I've also tried all different firmwares and SIMs from various carriers. Visible and Verizon are the only ones that don't work.
It's running Android 12 latest firmware. I believe it was originally purchased from Verizon but it's now on U1.
What does it say under service provider software version under software information? Vzw/vzw, vzw/vzw?

Yes, four VZW codes.
It's strange because when I reboot the phone it will briefly connect to 5G then immediately disconnect and say "Emergency Calls Only". My SIM is activated and works perfectly in my OP7 Pro.
I can also use T-Mobile and ATT Sims in the Samsung.
Ok, so if I lock it to 5G or LTE then the data works. But calls and texts don't work no matter what.
So I figured it out. It seems to have been a hardware issue with the phone itself. I ordered a different S21 Ultra just to see if it would work and it accepted my SIM immediately. For whatever reason it wouldn't accept Visible or Verizon SIMs even though it was unlocked.
Bit frustrating I wasted several days trying to figure out the problem but at least I figured it out. Posting this here in case anyone has a similar issue with a second hand used S21 Ultra.
I had a s8 plus that wouldn't connect to visible and I went through all kinds of heck. I finally figured out that because the firmware was u1 that it was not compatible. When I flashed to a u firmware I was able to connect to visible. I also heard the nines and tens had the same issue. It may be that Verizon puts a block on u1 firmwares
Also I think I had to manually change a few settings for my APN after I change to a firmware ending in u.

It's funny how Visible will not accept The s21 Ultra when I have net10 5G on Verizon towers. Been that way since I bought the phone new last year.
