In my town ATT upgraded its cell service to 5G VOLTE HD. About that time my phone and others could not send or receive calls.
ATT also turned off 3G. Some phones cannot then work at all. ATT has a list of phones that would work, and this one was on that list.
However mine was not working, but I could send and receive texts. I heard from some others that perhaps I would need a new simm.
I went to the phone store and got one. That did not fix it. I brought it home and decided that perhaps I needed to upgrade the phone.
I had not upgraded the phone much since the bootloader is locked, and I was waiting for an exploit so that I could get root.
But not being able to use my phone convinced me to try upgrades. I just began upgrading. After each upgrade I checked to see if I could place a voice call.
Eventually I succeeded. I did another upgrade to a newer android version and then stopped. My phone now has android version 10, one UI version 2.5, baseband version a505u1ueu9ctl4, and kernel version 4.14.62-19996794. Now I don't have to buy a new phone, and this one was not that old anyways.
My phone is a samsung A50 us version with a bootloader that can't be unlocked.
My AT&T N10+ N975U is running on Pie. It transitioned seamlessly with no changes made on my end. It was already using 4G VoLTE though.

we have 3 Note 10+ my son ordered his the day of the preorder release. he has the 256 version and my wife and i got the 512 version.
Upon my wife and I getting the phones we replaced the sim chips with new ones from AT&T instead of removing the ones in our Pixel 3xl. I noticed that AT&T Visual voice mail wasn't there but after loging into our voice mail account it downloaded a different visual voice mail program.
however we are having signal problems, I noticed that we didn't Get Voice over WIFI, Advanced Messaging, Volte etc. I called into support 611 and explained and they said that they would re-register our phones to turn them off for a few min and back on and should be ok.
That didn't' accomplish anything. I talked with an engineer that I know that works for AT&T and he said that my son's phone is provisioned for VOLTE with torch i think but not in the account screen. My wife and my devices are not provisioned for VOLTE HOWEVER NONE of our phones are connecting for voice or data to 4G LTE only 3G. He didn't know why but would check further.
after complaining to OOP with Samsung and being within the return window they said that we could order from them the branded AT&T phones and return our unlocked phones.
I realize that we will get stuck with the bloatware, but if we are getting 4G LTE VOLTE etc. maybe that is what should be done.
If we do that can we still get them unlocked and what do we loose by doing this? I appreciate the work everyone is doing here and I think hopefully I can get an honest answer vs everyone pointing the finger at everyone else.
My big concerns are:
If I keep these what do we loose?
How bad is the bloat ware?
If we change to T Mobile or others later can we, or if we travel, get AT&T to unlock the phones
If I keep these phones and flash the AT&T files will we:
Then get access to the programs and services we don't have now?
Get over the air updates as they are released?
I would highly appreciate any advice
Thank you for everyone's help in advance
I was getting horrible battery usage on my At&t branded Note 10+. What I did was flash the U1 unlocked firmware, set things up, made a few calls, sent a few text so things provisioned to At&t. I then flashed At&t csc with odin and this gave me 4GLte..wifi calling..video calling..advanced messaging..and volte

but your phone was branded AT&T right so theIMEI number is active in their system
I had the same issue - thankfully, I was able to test a friend's SIM card from AT&T and his worked! I saw an obscure reference (see below) to it being an issue with older SIM cards. I'm heading to AT&T store to replace mine tonight.

Hey guys. I just got a new S20 plus and it was Sprint branded phone. After tmobile bought sprint, they rolled out an update to download all the carrier stuff to the phone to make it work on Tmobile as soon as a SIM gets inserted. That being said, every time I reboot the phone, it's still running sprints ODADM or whatever software to check the network and make sure everything is fine, so it is definetly still running some sprint stuff.
Is there a way to nuke this thing and make it think it's a tmobile phone from the get go? Like it even has a tmobile boot screen now, but it's still running all the Spring network stuff.
I made a call and got a message that my phone would no longer work on their network since they are upgrading things. This phone isn't that old. I wonder if their system doesn't recognize it. The lady said their system was showing it was a 2g phone so I told her it handles 4g. She said on Cricket it's only able to use 3g. Does anyone know if this is true. I don't trust some operator in another country reading off a script. It sounded like they want everyone to buy phones from their website. I can't imagine a relatively new phone not having the right band. Maybe there is a setting I need to tweak or flash onto my phone if I'm only using 3g on Cricket. I'm sure I've seen my antenna say LTE. Or maybe Cricket is screening out non Cricket phones.
Check it's specs.
If it supports the needed 4G bands it may need to be reconfigured. I haven't a clue how to do that.
Maybe Access point names but it may go deeper than that.
I'm going to google and see exactly what specs Cricket will require. I think you're right and maybe something to reconfigure. I can't imagine Cricket shutting off tons of new ish phones just because they aren't bought from Cricket. Ran a speed test now and got 2.77mbps download and 8.49mbps upload. I am showing LTE now which means I'm not on 3g as she was saying now. I bet it's a sales gimmick to scare less savy folks. What mean loose phone signal in Feb hehehe.
Edit: I was on wifi when I got the message so maybe when I phone is on wifi and not using their LTE network it doesn't detect anything which is why they told me I have a 2g phone. When I shut off wifi LTE popped right up so it's probably a glitch in their way of informing us.
Edit2: Spoke to a tech at Cricket and he said my phone currently isn't compatible with them aaahahahhaha dumb. I told him I'm currently using it on LTE just fine no issues. He didn't have anything to say when I asked him since I'm not using 3g then it shouldn't affect me. He just said he wants me to have great service so buy another phone from Cricket. BS

Yes I was able to download that list when I googled. Judging by what it said these are phones that are tested and will work, not so much that other phones won't work. My phone was originally branded for Tmobile so I'm sure they wouldn't have tested it but it would have only had a different OS with Tmobile bloatware which I took off. The cricket people said their LTE isn't changing so I shouldn't have an issue but it will be interesting to find out. They must have just been looking at this list which is why they said my phone currently isn't compatible.
Funny this was asked but no answer given from ATT. I'll keep googling

I read a discussion here from 2019 someone else asked and the different variants are by region as they usually are for the different LTE frequencies. 1905 is North American, 1907 is Tmobile in North America so I would imagine my LTE frequency is still going to be fine. Those that bought Chinese phones etc probably not.
This is weird. The current ad for it on Amazon says it's currently not compatible with ATT and Cricket. I wonder if me flashing another OS for North America or USA I forget is why it works fine? Maybe I'm screwed hehe
*** NOTE: Due to changes with AT&T and Cricket, this phone currently cannot be used on AT&T/Cricket.

I work at a prepaid carrier store (not Cricket) and am having to tell customers the same thing. It's not just about if your phone has the radios necessary, they have to have the IMEI approved in their system and if it's not then you can possibly escalate to someone who can help get it approved but you probably won't get very far. I can't activate my own OnePlus device with my company either, even though it's currently running on our parent network. I have spoken with internal support folks about it multiple times and have gotten nowhere so I gave up.

Believe it. It sucks and it sounds insane but it's really happening. For me? I have to tell everyone with a Samsung Galaxy S5-S10 that they have to buy a new phone to be compatible with our new network changes. And I can tell you here that it's (probably) not the sales rep lying to you to make a commission sale, our tools are indeed forcing us to do that.

I'm just wondering why they are saying my phone currently isn't compatible when it obviously is. It works great. Even streams HD in an instant on Crickets network. Corporations aren't super efficient at checking all things under the sun. They are just checking phones they approve. They told me the same thing that my imei currently doesn't work but it does. Unless they are trying to be like Verizon and only allow specific phones in the future I'm still thinking once they shut off 3g then when someone wants to switch from Tmobile to Cricket with their unlocked working fine non 3g phone they still can or are they saying no they are going to be like Verizon and it has to be a Cricket branded phone. I don't think it's the later. I think they are just saying what will work, but not saying what won't work. Let's find out =( hehe
Read a discussion from 8 months ago. Seems like most are fine, one guy with a 1905 had issues on ATT. One guy did what I did so maybe that's why mine is fine for now. I haven't had issues like dropped calls etc but maybe the real issue I will have if Cricket adds wifi calling and VoLTE is if they use a specific frequency and the 1907 is missing it then I won't be able to use those. If Cricket only uses VoLTE then yes I am screwed in February =/

"I am currently using a 7t that was advertised as factory unlocked on ebay, when it showed up and I turned it on the big bright pink Tmobile boot logo came by. I did some research and found the convert to international/global thread on xda, I got rid of the crap hydrogen OS that came with the "unlocked" Tmobile phone. Using ADB I was able to flash the international firmware Oxygen OS and haven't had any problems with at&t now."
If it's an IMEI issue, flashing with the hd1905 fw probably won't help matters. I have a hd1905 on cricket since 2019, everything but wifi calling works. The same cricket sim in a samdung s9+ yields working wifi calling.
So while the hd1905 and 1907 are essentially the same hardware devices, the serial #/imei may determine what happens come 2022.

Yup, I'm wondering if the hardware or the IMEI will determine things. I didn't even know Cricket had wifi calling. Did Cricket even let you download the wifi calling app but it didn't work or did they not allow you to download it?
Edit: I looked it up. Looks like wifi calling will work on phones that have it built in to their OS settings. I probably won't use it if I end up buying another OnePlus phone. I wonder if there are any phones where wifi calling is working on Cricket that isn't on the list but is in the OS settings.
Wifi calling app? The s9+ was hybrid flashed. Everything but the main OS came from the U firmware (carrier), while the rom came from U1 fw. Result was working carrier features (volte/wifi calling) without the bloat.

The s9+ is probably the same as the s9 as far as the wifi calling since "+" isn't mentioned on their list.
Huh? It's right under the s9.
Dear Experts,
The cell phone I've been using
here in the USA is a Motorola G7 Plus,
with the Lineage 17.1 OS.
Yesterday, March 2, 2022, I couldn't
make a phone call. Immediately, the
call would end, and a message displayed:
"Call ended".
The folks at the ATT store in the mall
immediately suggested that I get a new phone.
My question was, why was I not warned about this?
It's been planned for a while now.
T-Mobile, Verizon, AT&T, and Sprint 2G/3G/4G LTE network shutdown dates: the sunset!
T-Mobile, Verizon, AT&T, and Sprint 2G/3G/4G LTE network shutdown dates: the sunset!
When are the carriers retiring their legacy 2G/3G/4G LTE networks? Here are the dates...

However, ATT docs says that the G7 Plus will work.
Mysterious.

After swapping my SIM card with various
phones, turns out the issue is the Lineage OS.
Results:
...
Motorola G7 Plus, Lineage 17.1
- call ended
Motorola G7 Plus, Lineage 18.1
- call ended
Samsung Galaxy A32, out of the box Android
- calls work
Motorola G7, out of the box Android
- calls work
...
This is disappointing, as I like to use Lineage.
I've been looking at the Lineage compatible devices:
Devices | LineageOS Wiki
wiki.lineageos.org
Of the 165 phones there, many look to be a
number of years old, and would not be a
candidate to work with ATT 5G.
q1:
Is there a setting that I need to tweak to
make Lineage work with ATT 5G?
q2:
What current phones can be converted to Lineage, and
are now compatible with ATT 5G?
Is there a list/link?
Or does anyone speak from experience?
Thanks a lot
I found out that it wasn't necessarily my phone. Over the past 5 -7 days in my area and maybe everywhere, ATT was doing switching to eliminate all 3G. I had been warned last June that this was going to happen and even tho my phone was VoLTE and 4G, consumer cellular was adamant about making me get a new phone, so I bought their samsung A01for $100 just to shut them up. Consumer Cellular actually shut my service off, forcing my hand and that was when I was living down in Alto Texas. However, I didn't like their phone because it was all googled up and I went back to using my Moto G7 plus with LineageOS. It has been the phone I depend on and I like it best. When my phone stopped working a couple days ago, it was right after an update, so I assumed the update was the problem or my phone was haywire. Then, I found out thousands of people were having the same problem from https://downdetector.com/status/att/ and they do consumer cellular, too.
Now, the new minimum requirement is to be 4G LTE compliant.
After giving up on Moto G7 plus, I put my sim card into my old Galaxy S9+ and it worked. I made a phone call and talked for more than an hour. After I hung up, I tried to make another call and as soon as I dialed, I was returned the message, "call ended" and I couldn't get it working again. So I moved the sim card over to the phone that Consumer Cellular sold me last summer, the samsung A01 and no mojo. I messed around with it for an hour or so. Also, I forgot to mention that whenever I put the sim into a different phone, I would get a text message from Consumer Cellular letting me know that they have somehow configured my phone to work on their network and I have no idea how that works because when tried to show someone the messages they sent me, they were gone as if someone had deleted them and I had no idea that the sender of a text could delete the sent message on the recipient's phone, nor push a configuration. Long story short, nothing worked.
I stopped in at the local ATT store, today. The guy looked at my phone and changed 1 thing (my APN) and it started working. He changed it from Pure Talk USA (att.mvno) to ATT Nextgenphone (nxtgenphone). So now I can make phone calls and check my voice mail etc.... however, I am NOT able to use data from the tower. My wifi works, but I should be able to get data from the darn tower. no luck. I just wanted to let everyone know that I dont think it's my phone. I think it's consumer cellular and ATT or maybe just ATT because consumer cellular uses ATT towers.
I have a Samsung S21FE (Snapdragon) model SM-G990U bought from Samsung and originally configured for Verizon. I've used it on the Verizon network since I got it, but just recently switched to T-Mobile. The phone is still using the Verizon firmware however data IS working, as well as calling, texting, and voicemail. But there are still a few things that don't seem quite right and I'm wondering if a firmware update would solve it (also, what is the best to update the firmware?).
For instance, I used to see "5G UW" when I was on Verizon, and now on T-Mobile it should display "5GUC" but I'm just seeing "5G". Also, when it boots up I still see the Verizon logo. Also, even when it's displaying "5G" I am not getting true 5G speeds --> more in the range of 70-100 Mbps. I use the OpenSignal app and it tells me other T-Mobile users in my area are getting way faster speeds. I thought the S21FE had all the necessary bands to get full 5G but either it doesn't, or maybe the firmware is blocking it?
For comparison, we also just switched my daughter's Galaxy S21 at the same time from Verizon to T-Mobile. On her phone, the first time she booted up with the T-Mobile SIM card, she started seeing the T-Mobile logo on bootup and now she sees "5GUC" next to her signal (I do not).
In the Software information section under Service provider software version, my phone has: SAOMC_SM-G990U_OYN_VZW_13_0017 VZW/VZW/VZW.
My daughter's S21 now says "TMB" in her software version.
It seems like her phone automatically updated the firmware over to T-Mobile but mine did not.
Again, not sure if a manual firmware update would solve any of the above issues, and what is the best way to change the firmware. Anyone have any experience with switching carriers on a S21FE? Did you update firmware?
