N9600 on AT&T, NO network/signal - Samsung Galaxy Note 9 Questions & Answers

I'm still using my N9600 device on AT&T (since the last year) and woke up today to realize the device is NOT registering on AT&T's network. I spoke to customer service & they're NOT sure what happened...
After speaking with the "advanced technical team" at 866-344-6217, guy mentioned it is the end of the road & the device cannot be re-activated on the network. Anyone else facing this issue?
Although I didn't swap/remove the SIM from this device, the customer representative said AT&T's system kicked the device OUT & replacing the SIM won't resolve this issue. Is AT&T trying to force people to move onto a 5G device deliberately?
I popped the (same) SIM into an A71 (T-Mobile version) that I had, everything started working... FYI

They started doing this months ago. And you can't whitelist imei either.

Just Google Phones that will work on At&t network. They have a list of devices they support

So its pretty much if its International devices and model number ends in F or G they will suspend your account if you put sim in phone and you have to call to have it activated again. You can't just put it back in device and your sim provisions...trust me I spent $400 on a Note 10 lite had it for 2months and this happened. Still have several International phones that no longer work. Most United States carriers will probably do this in the future

Sucks that they're doing this since a few months, sounds like I got lucky for more time than others have.
Is there any dual-sim 5G phone (Note-20 Ultra N9860 perhaps?) that is still expected to work with AT&T? I need to maintain 2 phone numbers (1 international number) due to work/business & hate carrying 2 different devices to accomplish this, this was the whole reason behind holding on to my N9600 for such a long time... Don't like iPhones, have been using Samsung for almost a decade now.
Any suggestions? Help appreciated...
Thanks

Problems with Unlocked Kaiser on AT&T

I've had my unlocked HTC Kaiser for 2 months now on the AT&T Network no problems. On Thanksgiving Day, my phone decided not to turn on after I left the phone to charge overnight. I figured it did not get a good charge so I tried recharging it. It was flashing red lights near the the top of the phone. So I go into AT&T on Friday to see if its the battery or the european charger that may be at fault. I played around a few combinations in the store and it suddenly/magically turned on. (I decided to buy the charger and extra battery anyways). The employee decides that for some reason or another, the phone needs a SIM Card. Well here is where everything went downhill.
After the new SIM card, I was unable to make or receive any calls, and no access to my data plan. Sometimes, I would have full signal bars but still was unable to make/receive phone calls. I've been able to make calls on very rare occasions; especially in this room in our school. What to give? So I went into another AT&T store and noticed that they had the incorrect IMEI number down in their system,. I asked for them to fix it but they said they couldn't change it for some reason and that the IMEI wouldn't be causing the problems I'm experiencing. So I finally called Customer Service Support on the phone and supposedly they were able to change it to the correct IMEI #. But still the same issues. I've done soft, hard, master resets, take out the battery + SIM card, you name it and still the same problem! When I took the SIM Card out of my phone and put it in a Blackberry, it did work! But when I took the Blackberry SIM Card into my phone, it did not. The support team told me that indicates that it is my phone; but I clearly told them that it could also be due to the fact that the towers just aren't recognizing my device no longer.
So I spoke to HTC about this and they said its the SIM card and they wanted me to go in and get another SIM card. So I went into AT&T today and got a new SIM card but same problem. Again, same issue. So I called AT&T Customer Support today and asked them to bump me up to Level II or III support. She says she cannot do that because my phone is unlocked (from HTC) and no support for that. I gave her the rundown on how my phone was working for 2 months until they put in the new SIM card and my cell phone activity clearly show that. Then she goes on to mention that other technical service reps that have helped me in the past few days clearly have pointed the culprit to be my device and not AT&T as they have exhausted all tests. And I told her, it's like taking a brand new car to a mechanic and then get the car back not running. If you ask the mechanic what did you do to my car, he's not going to admit to anything. She says that my device isn't being recognized by the towers. So then I brought up the point of "So is it my tower or is it really my phone?". I told her it's no problem getting a new phone but if I get a new phone, will it be unrecognized by the towers again. She said yes because it is unlocked. I said what about the thousands of other people who use unlocked Kaisers or any phone for that matter as they seem to have NO problems. They basically want you to buy the phone directly from them.
In all, I've spent nearly 10 hours on trying to get this thing to rework and be able to place/receive phone calls. Whether this is due to the events which ensued after the red light indicator on Thanksgiving Day OR the fact that AT&T switched my SIM Card and caused my device to be undetected by towers (whether it was due to the fact they put in the wrong IMEI in the first place or any adjustment they made to my account) remains to be determined.
The only options that remain is: 1) Go to TMobile and try out their SIM card on my phone and see if it works. I highly doubt they too will let me do that as they consider phone unlocked and don't want to help 2) Get a new phone through HTC and hope it'll work on AT&T again.
Any ideas or support??? heheh. your help is truly appreciated
I feel you pain Brother.......
I don't have a clue how IMEI and towers can just not register your device...though....but anyhow, did you check if you have the Phone in the Dialing screen-Menu-Options, then the tab BAND on the bottom and both of them selected as AUTO? if not, then try changing bands.......
If you know that then, I'm thinking only of AT&T could have blacklisted you or some sort.......but that is highly unlikely......
I had some problem like that when i'm out of the country using Foreign Chips, and it seems the Kaiser needs a bit of time to adjust to new sims, and that can take minutes, hours...or even days......who knows what is happening as the phone is "learning"....... hope this helped you a bit....
I've been using my Kaiser for several months now and I did not register my IMEI, I just popped the sim out of my 8525 and took off running. It sounds to me like your phone has failed in some way, especially if your new sim works fine in another phone. The question now really is, where can you get a Kaiser fixed in the US? I spoke with HTC on another subject and I get the feeling that it may be difficult. I got mine from a shop in Canada, guess I'd have to go thru them.
In any case, good luck, it will be interesting to see what it turns out to be.
I second RemE -- like him, I bought a Tytn II & plugged in the SIM from an older phone (in my case a Qtek 9100 not bought through AT&T/Cingular), and have had no problems.
i had a similar problem with my 8525. I bought a Tilt to replace it, and about a week later I gave the 8525 to my son to use. neither his SIM card or mine would work in the 8525, but they worked in other phones. I brought the phone to the AT&T store and the guy there did something on his computer, then the phone was able to work. I'm not saying that AT&T blacklisted it, because I don't really know. But it took a change by the AT&T rep at the store to get the phone working again.
I have been using Kaiser with ATT for three months now with no problem. I just used the sim card from my Blackberry and so far, no problems.

[Q] Need Help: Using In Japan

Hello. I posted this yesterday in the Nexus S forum (I have an S, not a One) but no one seems to know the answer so I was wondering if perhaps someone here could help out, as the Nexus One has been out for some time now.
In a nutshell, I would like to know how in the world I can get my unlocked Nexus S to work in Japan with respect to data transmission.
Early this year I developed an interest in foreign smartphones as all we had here in Japan was the (IMHO) horrid Xperia X10 and the wonderful HTC Desire. I have purchased a number of phones from overseas (either Hong Kong or the UK) including:
HTC Mini (HK)
HTC Desire (HK)
Xperia X2 (UK)
Galaxy S (UK)
Galaxy Tab (UK)
Nexus S (USA)
Now here's the thing: ALL of these phones were unlocked yet NONE of them allowed any data transmission except the HTC Mini. To this day I fail to understand why.
When I got the HTC Mini, I was using the Mopera U APN/service. I put my Docomo SIM card into the Mini and without doing anything at all, it had data connectivity from the start. To this day I question if it was something related to Windows Mobile, as all of the other phones I listed above are Android (except for the X2).
I had Mopera U with all of these other phones and yet NONE of them work, even after I have tried multiple APN services and have manually typed in the APN settings (i.e. mpr2.bizho.net, spmode.ne.jp, mopera.flat.foma.ne.jp, etc).
Just yesterday I received my unlocked Nexus S from the USA and while it hardly came as a surprise, I am nonetheless infuriated once again that the phone refuses to connect to the wireless network.
It should be noted however that the very first time I attempted to connect the Nexus S to the mpr2.bizho.net APN, for a scant one second, the 3G data transmission icon appeared in the taskbar at the top of the screen, but then immediately disappeared. Since that initial setting, it has never reappeared when I toggle the APN.
Can anyone please offer some advice here? I fail to believe that there is absolutely no way to use this phone in Japan. With all the different network bands and whatnot supported by this phone, surely it has to work. I am still at a loss as to why the Galaxy S and Galaxy Tab failed to connect to the network here when both are in fact, available for purchase domestically. Are the manufacturers actually creating modified band phones for each country despite making the same exact product?
Docomo is absolutely no help whatsoever, claiming that the ONLY band supported here is "3G" and denying any understanding of the other band spectrums (i.e. Quad Band GSM, Tri-Band HSPA, etc).
Some of the IT-related people I know have suggested that my phone is in fact, NOT unlocked and thus the problem stems from that, however considering that the phone will instantly register the NTT DOCOMO network and I can make calls and receive SMS messages, I fail to believe the phone is locked.
I will bring up a point that a friend passed onto me: They suggested that perhaps my problem is that the phone won't work because the previous carrier settings are still on it. The seller on eBay however stated that this was a factory unlocked phone and thus I don't think this applies, though I was a bit confused as to why there was a T-Mobile SIM card inside the Nexus S box, which led me to believe that perhaps the phone is unlocked but it is "defaulted" to T-Mobile network values?
Anyway if anyone could be of some assistance here I would greatly appreciate it.
You seem to know your stuff -- so I'm baffled as to why this isn't working for you.
You're armed with the Docomo APN and authentication, as well as compatible hardware. NTT Docomo (as well as SoftBank) operate 3G/UMTS/HSDPA on 2100Mhz, which your Nexus S supports.
Each year I visit family, I get a rental SIM, get the spiel that loaner SIMs aren't allowed to be used in smartphones (might have changed now). So they give me a phone instead, which I just rip the SIM out of and place in my phone.
I doubt your previous carriers' info would be interfering, since I'm guessing the only entry you have under operators is Docomo (and removed every other carrier), and you have your FOMA SIM inserted.
The only thing I can think of are: your HTC Mini's passing some authentication type handshake (or maybe it's a parameter or setting its' flipping), or the network has some strange blanket ban on IMEI numbers.
Both scenarios are pretty unlikely -- which brings me back to me being baffled. I was able to rip out a SIM and use in a Nokia E51 and an HP iPaq 910 (a handset not sold in Japan). I just entered in some APN settings and it was happy as pigs in ****.
I'm sorry I don't have anything more to offer -- but from what you said, and you are correct -- this should work.
This might sound obvious : Sometimes, Android will have a database built in with APN settings and will use those. Sometimes, It'll read the settings off of the SIM, and use those. Some cases, the auto-selected values might be incorrect if the carrier changed something on their end. Or sometimes, it might not do anything at all. You might have already tried this -- find a working handset (HTC Mini, friend, demo unit in a store, etc), write the settings down and enter them in by hand on your Nexus S. If you've already tried this, I apologize.

[Q] Nexus 6 Verizon Network problem

I've had a T-mobile Nexus 6 on Verizon network since Thanksgiving. I've had no problems at all UNTIL today. Woke up and my network symbol has an exclamation point next to it and when I try and make calls it sends me to Verizon's customer account services. Also, a dropdown bar with the words "sign into network" appear. After clicking on it it sends me to the Verizon's broadband page.
Anybody else have this problem and no what to do? Wanna run this by before I call and navigate customer service.
Edit: My account is fully paid and up to date
Try reinserting the sim card and reboot with WiFi off. Otherwise you might need a new activated nano sim.
Its weird that it'd suddenly become deactivated though. That would suggest they cut you off intentionally.

Yeeup. I've tried a factory reset and exchanging the sim. I put my wife's micro sim in and it deactivated her whole account. Verizon did this on purpose and I'm not happy. I've been using this phone for 3 months with NO problems
So any sim inserted to your N6 has the associated account deactivated? What did Verizon support say when you called them?

Okay, so I called Verizon and the tech could not get my phone activated. She said the phone number on that account wasn't working. While this was going on I randomly checked my EMEI number on Swappa and my phone was just reported Stolen/blacklisted! Although I bought on CL unopened in box with triple-checked clean ESN. I've used it for almost 3 months with no issues and a clean ESN. I even registered it through Motorola's website. I am beside myself. I didn't say anything to the tech because she was determined to get it working and I didn't want to be like "oh hey, yeah by the way I just realized this phone is reported stolen".
Well, it is still not working and tech pretty much gave up. So I'm gonna go down to Verizon and see if there is another workaround. I don't know if this is the reason it isn't working, but all evidence says so.
Anybody have any ideas on if this phone can be used again? Am I screwed?
That's sucks how that can happen. I to bought my nexus from someone and I sure hope he doesn't do the same thing. They should see one you activate it and use it for a period of time. Then all of a sudden reported stolen, that is a scam.
Sent from my Nexus 6 using Tapatalk
Haha! Figured it out.... Finally got to a tech who knew what was up. I'm on a family plan and unbeknownst to me my inlaw had an ipad stolen and reported it to Verizon, which in turn deactivated and reported device stolen. BUT, instead of reporting just the ipad, they reported the phone too. Doesn't make a whole lot of sense. But the tech fixed it.
I told him it up front it wasn't a verizon "branded" device, that I cut my micro sim card down to fit it and he said no problem he would get it working....AND he did.
Similar issue
I'm having exactly the same symptoms as you mentioned, but on Swappa my IMEI comes up clean. I've talked with Google, Motorola (source for my N6), and Verizon. This happened right after a *611 call related to a billing issue. The sim in the phone is a microsim cut from my S3. Worked for about a month, then boom. Finally talked to someone last night that "fixed" my issue, but it's flaky and temporary at best. The tech support person activated my phone as my old S3 somehow, but it does seem to work. One of the other Verizon techs put in a service request to add my IMEI to the Verizon database, but it was denied because of differences between the firmware/software on the Verizon N6's making mine "not safe" to be on their network. I'm looking for a long term solution. Every time I jump off WiFi I get the aforementioned network exclamation point and then it comes back. I'm wondering if the phone had Verizon's firmware version if they'd activate it? I think my IMEI is blacklisted?
I didn't want to start a new thread since this is similar.
Hoping I didn't break any other rules. Any help would be greatly appreciated.

SM-G973U VoLTE

I recently bought an unlocked Galaxy S10 SM-G973U on Amazon. Got new SIM card from a Verizon MVNO and activated phone. The phone downloaded Android 12, One UI version 4.0. Firmware Build number SP1A210812.016.G973USQS6HVA1. Service provide Software version SAOMC_SM-G973U_OYN_SPR_12_0007 SPR/XAA/VZW. The problem is there is no menu option to activate/switch on VoLTE which means when I'm on a call there is no internet. I've talked to the MVNO tech support multiple times and was told they couldn't see any problems on their side, or that the SM-G973U does not support VoLTE which is not true. I found on one of AT&T's sites that the SM-G973U needs a software patch to enable VoLTE. I also found a couple of USSD codes but they either didn't work or didn't get me to the right setup screen to turn on VoLTE. I even stopped by a Samsung store and they weren't any help either. They said they could re-flash a stock firmware but it would revert to being locked to a carrier which is apparently also not true based on what I've read on this forum. Anyone know how I can turn on VoLTE or know of an apk file or software patch to enable VoLTE?? Does one of the firmware versions posted online have the patch to turn on VoLTE??
I think the issue is that your phone is showing SPR/XAA/VZW. You say you're on a verizon MVNO (who, by the way?)... but your phone isn't seeing that. It's actually saying it's active for SPRint. The second one, XAA, means it's not able to detect the SIM type... and the third was that it was originally VZW, which you can't change and isn't really relevant. (That's just what the phone was "born" as).
Bottom line, your phone isn't seeing VZW or an MVNO as the active CSC nor the SIM card. In the past, the easy thing was to change the CSC to what you need, but I haven't found a way to do that actively. What's supposed to happen is that the CSC should update based on the SIM card and cell signal you're getting... but this doesn't always happen. I bought two phones - one switched with no issues, the other I could not get it to change no matter what I tried.
That said, the easiest thing is to clean flash the phone with ODIN to a VZW or your MVNO's ROM, so that (hopefully) the CSC updates automatically. You could also consider flashing a U1 (unlocked) ROM, as yours is not technically an unlocked ROM (U means it's a carrier ROM... which may be why it's not switching over?)
Again, I tried all of these on the second phone I bought, and nothing would switch it (my carrier is Total Wireless, which is a VZ MVNO, and actually shows up as Tracfone (TFN). I had to return that second phone and get another with TFN already activated, and that worked fine... so be sure you do this before you drop out of your return period.
Bottom line, you should be able to get this all working... my VOLTE/VOWIFI works fine... just a matter of getting you there.
Thanks. My carrier is Straight Talk which is now VZ. The SIM card they sent me has the wording "Verizon Compatible" written on it. I finally found a document that explains how to interpret the CSC codes and your explanation clarifies my understanding of it. Sound like I'll have to re-flash it. Since it was originally a VZW phone I'm thinking I should flash it back to VZW to see if that works before trying U1.
Dumb question as this is my first time flashing a phone. (I've flashed quite a few other things but never had to worry about CSC codes and bootloader versions, etc.) I don't see VZW firmware on samfirms or sammobile. I see Sprint, T-Mobile, and one listed as USA without carrier info but I don't see one for VZW. Can someone point me to the correct location to download SM-g973U and U1 firmware for VZW? Greatly appreciated and thanks for putting up with my lack of knowledge!
Edited: Found the files on sammobile. Will try the U1 (VZW) first. I'll keep my fingers crossed.

Success! Was able to flash U1. VoLTE is now working. The CSC now shows TFN/TFN/VZW. Much appreciated!!!
Awesome, glad to hear that fixed it easily!
And TFN... I'm a fan there, too!
Hi! I'm having a similar issue with the same model and happy to see someone was able to enable VoLTE. However, most of what you said above is a foreign language to me. Would one of you be willing to give me a crash course in what you did?
Here's my specific situation. Last week (~1/4/23) Tracfone shutdown 3G. My Samsung Galaxy S10 (SM-G973U) says my network is set to LTE/3G/2G. I've read LTE is 4G, but still can't make or receive calls/texts, but data and 911 calls still work. Their tech support is no help.
From reading online it sounds like I may need VoLTE, not just LTE. Hence finding this thread. If one of you would be willing to spare some time to walk me through what you did I'd really appreciate it. In the mean time I'll try to figure out what "flashing" mean in a context that doesn't involve showing body parts
Thank you in advance!!
I'm on Tracfone (they were bought out by Verizon, BTW) - I was on Total Wireless before, which is now Total by Verizon. You might try contacting support again, as they are now VZ, and may have more help to offer.
My S10+ is running 975U1 now, and it works for VOLTE/VOWIFI properly. You may consider getting a U1 ROM installed, and maybe even the VZW (or TFN) version if available - that may get you working.
Did VOLTE ever work for you before on this or any other carrier? What is your CSC right now?

Thanks for replying! I'm not entirely sure if VoLTE has worked previously. I bought this phone 6/2021 and have only haver had tracfone service for it. I did find in my setting that VoLTE calling is set to on so it seems like it should work. Of note, the 4Glte in my status bar has always been grayed out (I went back and looked at some old screenshots).
My current CSC is VZW/XAA/ATT.
I spoke with tracfone customer service yesterday and they had me reset my network setting and now I don't even have data and the 4Glte in my status bar that was previously gray has now completely disappeared.
Their customer service refuses to talk to me now (literally no one answers when it transfers to an agent) or they hang up on me, and no I haven't been rude, but I have told them I'm recording the call.
I bought a mint mobile package last night because I'm beyond frustrated with Tracfone. I'm worried I'll have the same problems with Mint. I'm not sure if my settings are screwed up or if it's just Tracfone. In any case things are worse now after talking to customer service yesterday.
I also notice there was no APN setting on my phone so I updated it today and restarted but no difference.
Thanks for any input!! Much appreciated. Sorry for the novel.
Ok, so based on your CSC, the phone is not seeing the SIM's carrier - it's showing XAA which means it's using the default settings, which is probably why your not getting VOLTE. The active CSC of "VZW" may be ok... depends on which carrier you're on with Tracfone. I think they're VZW only, but I'm not completely sure.
You may want to just get a new SIM card and get that activated. HOWEVER, the problem you'll likely face is that the phone was born ATT (last CSC). This means the IMEI won't match a "compatible" phone to Verizon, and they will flat out refuse to activate it (even though WE al know it will work fine). If you still want to do that, you will have to activate the new SIM on a VZ "compatible" phone, then you can swap it to the S10. Note that VZ complains about this when you talk to them... so don't tell them you're doing this... but I've done it many times and it works fine.
If your actual behind-the-scenes carrier is ATT, then you can do the activation with your phone without issue.
If none of this works for you, you can switch carriers to an ATT MVNO and you should be good to go.

OK some of that was still over my head. I'll see what happens with the Mint Sim... one f/u question now though. You said the ATT means my phone was "born" ATT. I bought my phone off backmarket and it was sold as "unlocked". Was that not true? How can I be sure in the future if I buy a used phone that's not from my carrier that it will actually be compatible?
Unlocked just means it's not locked to a carrier. That is true in your case, otherwise you wouldn't have been able to install ANY non-ATT SIM. So, you did the right thing to get an unlocked phone, and that is what you got.
The issue with compatibility is just the asshole carriers spreading lies. They do this to try to get people to buy THEIR phones, for no reason other than to make money and confuse consumers. The "born" CSC has no bearing on anything, really... neither does the carrier-specified IMEI. In your case, the XAA is good, which means it's a multi-carrier ROM, which works with all USA carriers.
Mint is a good idea - being an ATT carrier (IIRC), that should work and they should help you get it up and running even if they have to activate it. Good luck!
Awesome! Fingers crossed!! Thank you for your time and all the info❣
I'll try to remember to give an update in a few weeks for future readers

UPDATE: Switching to Mint worked like a charm! Once my number ported and I put the new SIM card in, service was instantaneous! I've had Mint for 3 weeks now and the service is so much better than with Tracfone! My calls go through nearly as soon as I hit call, the internet is faster.
I didn't need to do a thing either. No making APN settings, etc. I'm betting it has to do with what you said about my phone being born ATT. So funny because the software(?) is Verizon - shows the Verizon when I restart/power up. I still love my bastard phone
So thankful I didn't buy a different phone!!! Again thanks for all your help @schwinn8
Thanks for reporting back and letting us all know, and I'm glad it worked out well!
Yeah, the carriers pull this nonsense all the time... it's BS. The phones are all the same, only the ROM changes. If we can change ROMs (which we can) then there should be no reason to force users to specific IMEIs. But we know why they do this - follow the money. I encourage people to write to the FTC and FCC about this (I have).

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.
