I have a Galaxy S9 (SM-960U) purchased from T-Mobile, but unlocked and running with an AT&T SIM (among others, at times). Up until today, the phone was running the stock T-Mobile ROM which received various software updates on a monthly or every two month interval. I've installed them as they were released (while running various non-T-Mo SIM cards) and the latest was October 1, 2018. Today, I clicked the "Software Update" function and saw that a new update was available. When it installed and restarted, I noticed that the phone was running an AT&T branded ROM, along with the typical AT&T bloatware (e.g., CNN, Groupon, Amazon, AT&T-specific apps) that was not previously installed.
The other thing I noticed was that the phone now is only connecting to HSPA and HPSA+ networks, whereas before it would also connect to LTE.
I'm not sure why I suddenly received and installed an AT&T-branded ROM today when my S9 and all of my previous devices were fine running the T-Mo ROM and receiving updates as they were released. Does anyone have any insights as to what caused this change and whether future ROM updates will be carrier-specific based on the inserted SIM? In the past month I've used SIMs in Vietnam and Japan and it seems odd that ROMs would suddenly be based on the carrier of the day.
Also, any ideas about restoring LTE service? I've tried removing the SIM and powering off the device a few times, but no dice. This was a network/account-problem when I initially ported over to AT&T from T-Mo which took a lot of troubleshooting at the store (unsure of actual root cause), but it seems odd that a software update on the device would undo that.
The latest update (3BRJ5) is BYOD firmware. With B firmware, a carrier sim will change the csc of your phone to match the network you are connected on. Good luck getting LTE back, I have no idea on that.
*#*#4636#*#* entered into phone dial. That will allow to select preferred network type in device information.

you have to change APN setting on the menu to reflect AT&T network. let me know if it works by changing APN.. I used to have S9+ tmobile and I was waiting for this BYOD update but i traded in my s9+ already =/ i have note 9 unlocked now..

The issue required a visit to the AT&T store, where they replaced the SIM and reset some of the network features on the back end of my account. This required a call to the retail technical support team and about 45 min. No settings were changed on the phone. The APN settings were already configured correctly (which I had confirmed as a part of initial troubleshooting).
The phone works fine now, though some features like AT&T HD Voice and the AT&T Call Protect app still don't work. I've tried contacting them twice about it and they opened a ticket but it hasn't helped. These aren't features I used before so I don't really care.

Keep in mind though that HD voice only available to postpaid At&t only not prepaid and they do required special sim card for hd voice but since you already changed sim card then the problem is not the sim card. You can try and dial #*#*4636*#*# and see if Volte is provisioned.. I wish i had my s9+ from tmobile but i dont have it anymore i was waiting for that byod software update.. Hd voice should work on BYOD custimization update on at&t

Hello! I have an unlocked Galaxy Nexus on the Bell Mobility Network in Canada, that I have a US T-Mobile prepaid SIM card for traveling in the States, and getting cheap data: yay for $3/day unlimited talk, text, and data! I was away a month ago, and just noticed today, that I was unable to send picture messages. The phone said to check my APN settings, to which I said, "Wtf does that even mean?" and googled it. Upon figuring it out, I checked the settings, and it still had my T-Mobile info in there, not my Bell settings. I changed it, and everything is hunky dory, nbd.
My question is, why didn't it automatically change, when I got back to Canada and put my Bell SIM in? Also, when I got to the States, I had difficulty joining the T-Mobile network. It was stuck roaming on AT&T and I couldn't access data. I had to physically make it join the T-Mobile network, by going into the mobile settings, hitting network operators, and selecting T-Mobile from the list. I happened to figure that out on my own, purely by accident. I didn't have to do that, when I originally got the T-Mobile SIM during black Friday. I just popped it in, and it worked. My Bell APN settings were fine upon returning after Black Friday too. Does anyone know why the issue this time? I was only running the previous version of Jellybean back in November, the phone has since updated to new Jellybean, could that be why? Or is my phone crapping the bed?
Thank you for any input :0)
PS phone is unrooted and running stock Jellybean 4.2.1
I've got my unlocked S9 from Samsung. I have a Redpocket CDMA sim card, which works fine in a Samsung S7E and a Google Pixel. However, when putting this sim card in S9, the S9 could not get on its network. It shows Emergency calls only and "Not registered on network" when making a call.
Sometimes it shows "refreshing sim card data" and no network. When turning to network modes, it says "LTE/3G/2G" etc but redpocket cs seems to believe the right one should be "LTE/CDMA" instead, which is not in the list.
I tried various usual ways such as factory reset etc, which did not change anything.
I tried a project Fi and a verizon sim card in the S9 and they were recognized with no problem. Thus I think the S9 is not defective.
I did some searches and people mentioned S8 had the same issue too: https://forum.xda-developers.com/galaxy-s8/help/unlocked-s8-failed-to-register-red-t3736850
I am wondering whether anyone has this problem or a solution.
Will flashing to verizon firmware help?
Thanks.
I'm having the same issue with PagePlus! I just put the SIM from my VZW S6 into my unlocked S9 and when that didn't work I chatted with support to do an ESN change (I thought perhaps PP needed to do something on their end). I was told if there was no "LTE/CDMA" option that the phone wouldn't work on PP.
I tried using an app to switch between different network modes (including the LTE/CDMA/UMTS auto which my S6 uses) to no avail.
I'm tempted to try flashing the VZW firmware, but the post here makes me wonder if it will accomplish anything.
I tried that APP to force network mode too but it did not seem to work.
As an update, Redpocket customer service is really great that they moved my number from Verizon network to their GSM/ATT network, and everything works fine now. I do not want to try flashing verizon firmware for the same reason...
Too bad Samsung could not get such a simple thing right.

Can we sue them?
I faced the same issue too. Apparently, Samsung does a setting update that prevents the sim from registering for Verizon's MVNOs. I called them and they said they NEVER heard of this issue. Apparently, you all did too. I am tempted to sue Samsung for this since this could be an antitrust issue. They are preventing competition by working with Verizon and feigning ignorance.Can any of you comment on this?
I was going to go with one of Verizon's mvnos. And their SIM card would not work and I did not realize it until I spend the $40. I had to put an actual Verizon sim in my unlocked phone to use the Verizon network. So either Verizon is blocking the S9 on mvns or the mvnos don't have the updated information for the S9. Total wireless told.me it Had to be a Verizon branded phone for it to work. So I think if someone flashed the Verizon firmware on the unlocked version it probably would work.
i dont see anywhere on the post where you contacted the MVNO provider, to register the ESN or IMEI of the device.
Also does this MVNO even allow BYOD?
i remember I had a line from Cricket or Metro that had a sim card, it worked on my Nexus 5x, however inserting it to another nexus 5x, it didnt work, I had to call them to register my IMEI
Hey guys this is an old thread, but maybe this will help someone. My old Red Pocket SIM would not work on the S9, but my renewal came with a new SIM, ending in 8222-15XX (old was 8180-50XX) For ****s and giggles I put it in and it showed LTE/CDMA and verizon. Had RP CS switch my active SIM and now it works with no workaround!
TL;DR Try a new RP SIM if you are using one a year old or older.
I also have similar issue.
Where I used to get lte over voice, but no longer getting after a recent update from samsung. Using Redpocket cdma sim
Now I have lte and voice, but dont get lte over voice even though redpocket said they have enabled Volte on my line
We just added an Unlocked Galaxy S9 (replaced S5) purchased from Amazon (Black Friday sale), ordered new Sim from Pageplus (MVNO using Verizon ), called them to transfer the phone number, popped it in and the S9 configured itself for Pageplus, and everything works perfectly...

That's great news. I switched to GSMA due to CDMA issue. I will switch back to CDMA after my current plan expires.
I heard that RCS (messaging via wifi connection similar to imessage - samsung messages app supports it in pie I believe, not sure about oreo) is active in verizon now including mvnos. Have you tried it?

I tried for my unlocked note 8. For the new sim coming from red pocket, it works great at the first time. But later when I switch the sim to a GSM sim for international travel and then switch the sim back to the red pocket sim, the same problem appeared. I have to use verizon sim to get LTE/CDMA back in the emergency mode.

I think you've found the answer for those who are unable to get their existing RP SIM to work on the S6-7-8-9's running OREO or PIE. I just took a later serial numbered CDMAV SIM (89140000018821472XX), inserted it into another S8+ that I have, booted it and saw the Verizon Wireless scroll across the top. I'll chat with RP today and see if they will switch the ICCID numbers between old and new.
After countless hours looking into this problem, I tip my hat to you for the solution provided.
Try as I may, in the end it didn't work for me.
It worked for me when I flashed the latest un-branded U1 firmware G960U1 UEU6CSI1 via the patched Odin, from:
https://updato.com/firmware-archive-select-model/?record=E68EDDB6DBFB11E99E59FA163EE8F90B
I've also done a full factory reset from recovery after the flash.
I guess they must have fixed it with the latest firmware updates... ymmv
Since the August update, both of my Verizon branded S8+'s work directly upon inserting a RP sim card.
POSSIBLE SOLUTION!! (YMMV)
I had a similar problem when I upgraded to Android 10. I no longer had CDMA as a choice for Network mode. Here is the solution that worked for me:
Step #1:
Go to the phone dialer and dial *#*#4636#*#*
This will bring up a new screen
Select "Phone Information"
You will be greeted with a scary-looking screen with lots of stuff
Scroll down and look for "Set Preferred Network Type"
Select "LTE/CDMA auto (PRL)" from the drop-down
This will give you phone service... but not data.
STEP #2
To get data services, you will need to create an APN.
Go to settings/connections/mobile networks/Access Point Names
Click on add and enter the following:
APN Name: Verizon
APN: VZWINTERNET
MCC: 311
MNC: 480
Authentication Type: None
APN Protocol: IPv4/IPv6
APN Roaming Protocol: IPv4/IPv6
I found that this APN worked for me... (YMMV)
Hope this is helpful...
are you folks still having trouble with this? it doesnt seem like a difficult obstacle to overcome
Thank you sooo much! Creating the APN did the trick.
I've tried everything, so hopefully someone can shine some light into this issue.
I bought a new (unused but from a 3rd party) Samsung Galaxy A50 (A505U) Verizon branded and unlocked. Got a sim card from Visible and went to get it connected. Nothing. WiFi works, everything works, but no cell service.
Here's what I've done (some multiple times)
- reset everything to include network settings, hard reset, etc
- removing the sim, resetting, putting the sim back in. I always get a notification saying the sim card is removed and it goes away when I put the sim back in, so it is recognizing a sim card is in there
- switched sims with another Visible phone/sim and nothing. Both sims worked on other phone but neither worked on this phone
- tried getting into the hidden menus but none of them worked
- talked to Visible tech support which upgraded the issue to the highest level and concluded it's the phone
- Visible believes it's the APN settings but I cannot edit current APNs nor add new ones (grayed out)
- manually add networks, I can see Visible, TMobile, ATT, and some weird numbers, but when I try to connect to Visible it says cannot register on the network, other networks say the sim is not setup for them
- sometimes I get the icon that shows all bars but they're grayed out, sometimes it shows 3-4 bars lit up, sometimes even shows a 4G icon, but mostly the grayed out bars
- sent the phone to Samsung, they tested it and found no faults, guess the hardware is good, ruled that out.
- got into dev options but I'm aware the OEM unlock is not on option on the A505U, not sure if I can change anything else.
I'm out of options. Any other ideas? I think if I can either get into the hidden menus I'll be able to diagnose it better, or if I can somehow change the APN settings I'll be able to set it up. Visible tech support thinks it's the APN, which makes sense to me, but I can't change them.
Any help is greatly appreciated.
I was able to get into the CSC change function, there's not many there, but would changing the CSC help? If so, which should I go to?
I've had a similar issue. Was working fine until the Android 10 update arrived. Since then, it won't work with my total wireless sim card. Tried 3 different sim cards on it, but nothing. Can't add it do anything with the APN, and getting into the phone info hidden menu doesn't help any. I suspect it's a bug in the new firmware or something like that. Works fine with a Verizon SIM though.
Update: Verizon SIM no longer connects to phone. Still works with LTE data. It seems that the CDMA radio quit working with the update to Android 10. Must have been collecting to the Verizon network with VoLTE until it updated the provisioning or something.
So, I finally figured out a workaround for mine that was able to get both data and voice networks to connect while using total wireless, which is an MVNO on the Verizon network. I pretty much narrowed it down to being an issue with the modem not working with CDMA. What I did was download the last Android 9 firmware and flashed just the modem (file starts with CP_) using Odin. After that, I rebooted it and voila! It connected.
Just thought i would give my experience as i just delt with this. i got my 10 update this morning nd let it update and apon a reboot i lost all mobile connection, a signal bar would show for a few seconds looking like it was trying to lock in a signal and it would go back to the ⌀ symbol. i tried flashing the android 9 modem from 2 different updates and neither fixed it. i just decided to order a new phone as i feel its time anyways. my next attempt will be to flash android 9 back using odin then just throw this phone up on craigslist
edit: odin successfully flashed back to android 9 and signal now works again. so if anyone has this issue you can try the method above of just flashing the modem and if that doesnt work you can go back to 9 and restore functionality of verizon mvno's

samsung a50 not connecting to VZW towers (red pocket)
My phone is doing the exact same thing and while I can appreciate how you resolved the issue it doesn't make much sense to me.
I use Red Pocket for my network. (Which uses Verizon towers - I use the CDMA Sim)
Before this major update to 10 my phone worked flawlessly. Now it won't connect to the network much like you guys have stated in this thread. Mine will connect intermittently for like 3 or 4 min tops and then get kicked off the tower and will actually not show any bars (Circle with a line through it) to show no service for about 10 or so minutes then restart the whole process.
I also have a work phone (2nd phone) that is directly tied to the verizon towers on the verizon network. If I take the sim out of that phone and put it in my samsung a50 the samsung a50 is happy and can make phone calls, send texts, and stays on the vzw towers with no disconnects.
If I take my red pocket sim card and place it in my work phone that phone also works just fine - send messages, make phone calls, and stays on the vzw towers with no disconnects. (work phone = iphoneXR - it's free, sue me)
Even though reverting the modem obviously fixes your issue I do not think that is the actual problem. It also doesn't seem that a third party carrier is being randomly booted off the towers, it seems to be a glitch with third party carriers using third party sims utilizing this new android 10 software that VZW towers do not like.
Which obviously points to an issue with Samsung's latest software not being compatible with third party carriers.
I can't seem to contact Samsung in a direct manner to resolve this issue as they want me to take it to a third party store to have it looked at. I spent 2 and half hours with tech support from red pocket and they came to the conclusion that VZW was doing "upgrades/maintenance" to their towers in my area. (whatever that means.
Any ideas on how I can contact Samsung directly to detail this issue to them? I really do not want to have to root my phone in order to use odin to set my modem back to version 9 as I'm hearing that doing so voids all kinds of implied warranties with the phone and it's only 6 months old.
Appreciate any help that you guys might be able to steer me towards.
Thanks.
Before this major update to 10 my phone worked flawlessly- They Told you the answer, Odin # 9 or if its under warranty take it back Good luck.
My phone (SM-A505U) wasn't even working on visible before android 10.
See my post at the end of this thread: https://forum.xda-developers.com/ga...official-firmware-t3955727/page2#post83845605
I have that problem too. Where I can download v9. I got the Odin.
*********UPDATE********** I bought a new sim from straight talk and VOLTE works now! (GSM compatible Straight Talk Sim card) My old sim was from 2014, so it wasn't VOLTE compatible.
I have an ebay zombie LG G710ULM flashed to latest Google Fi Android 9 software, I received an email from Straight Talk (Wal-Mart US cell phone service reseller) telling me that my LG G7 does not support VoLTE and my phone will be unable to receive calls in January 2021.
-Using a network info app, the app is telling me it is connected to T-Mobile towers (so I have a Straight Talk T-Mobile compatible SIM)
-I can't find any options to enable VoLTE in settings, and wifi calling is erroring out
I was wondering if there are ways to get VoLTE and Wifi Calling working (Straight Talk supports it, but not my current ROM/SIM).
I can switch to the following sims supported by Straight Talk.
-AT&T Compatible Sim
-Verizon Compatible Sim? If my phone supports CDMA bands
OTHERWISE MOST OF US WILL HAVE A PAPERWEIGHT IN 2021!!!!!!!!!
Same problem
I'm having the same problem. Any progress on this?
I'd like to know this too. Surprised there is no traffic here with all the knowledgeable people on this forum.
G710EAW here. BTW There was an Android 10 update just two hours ago from Android 9. Someone with an 'EM' phone in another thread said VOWifi is "working now" but how do others know if it's working when January 1st comes around?

If you guys have cross flashed roms, then volte will not work. It doesnt work for any of us who have crossflashed. Whichever model.
You need to be on original software. Looks like some licensing thing that volte requires. They need to provision volte for all the phones. Sounds like they are not interested to provision it for g7. Odd that even EAW model which has original firmware, they sent that mail too....
Sad/Odd to see your carriers are suddenly changing to only Volte.
Is there a way to put it back to original software? I actually don't need it crossflashed to anything because it's a Verizon originally and I would like to use it on that network. Or does it not work that way?

Main issue is that your carriers dont want to provision volte for your G7s. So no guarantee if cross flashing back to original will work.
There is crossflashing guide in guides section with which you can go back to stock firmware. Do this at your own risk.
In our country we have a volte carrier called Jio. They provide an app called jiocall. Using that app you could use their service even if your phone is not volte capable. You will have to see if there are such apps for your carrier. Thats the only non technical, simpler solution.
I have some information that might make all of you guys happy.
I was told by Safelink Wireless that VOTLE is a function of BOTH the phone *AND* the sim card.
Basically, if the phone itself is VOLTE compatible but the sim card is not, then the phone will be reported on their system as not compatible, and will ask you to upgrade your phone.
However if a VOLTE compatible SIM is inserted, if the phone does in fact support VOLTE, it will then work. That's because it's provisioned on the carrier via the sim card itself.
If you purchased a sim via the "Buy your own sim" package, e.g. online or from Best Buy, etc, awhile ago, then that sim is not compatible. You simply need to call Tracphone/Safelink and ask to buy a VOLTE compatible SIM (which costs 99 cents). Then when you get it, call their tech department to have them transfer the phone service and phone number to the new SIM.
You can dial the phone's service menu and go to the VOLTE/GPRI menu and if the options are there, then the phone supports it.
What's the correct service menu number for our phones?

Update, I recently bought a new sim and I have VOLTE right now on ULM android 9 latest security fix LG G7 image, running on Straight Talk.
took a while to understand lgup but my 710 oulm had a type oreo that the guy said couldnt be but i crossed flashed it to 10 i dont see the rom anymore and i hope i put it on another drive it was a canadian rom for android 10 works great otherwise im looking to get volte active in the *#*#4636#*#* phone menu you can see "provision for the setting under the radio on off but its a grey area the buttons dont work could be good could be bad its definately part of 10 but ?? grey areas preferred network could be sketchy to play with the phone initially on transition had incredible link up speed now its giving me a pain because assume i played with the connection preferences tab and its a registration error like dum just use the assigned sim guys and stop trying to mac or identify with every device anyway its the registration of a telephone number robo heads
Just updated this morning, we now have eSIM support (supposedly) with the second IMEI showing up in settings. I haven't tested it yet though, so ill try to later today.
Edit:
So my secondary carrier is GoogleFi, which won't recognize the available eSim. So I had to convert my physical TMo sim to an eSIM (permanently disabled your physical sim card). This allowed me to move my GFi card to the phone.
GFi app recognized the sim card and activated, however it looks like Samsung/TMo baked in a TMo network selection feature for this sim. Instead of recognizing that it's GFi with it's networks, you had to select if this card was a TMo/Metro/Assurance carrier. I selected TMo thinking that GFi uses them mostly around my locale that it'll work. However we now get the X on the signal chart.
My guess is this is the good ol network lock coming into play. So we got eSim and 2 sim cards...we're locked to TMo and Metro still. Hopefully better luck for those with Unlocked US phones
I have a Samsung version (still on TMO but not TMO branded) and got the update today with esim too
So new update: becareful with converting your Physical Sim to an eSim. I can't figure out why, and am on the phone with support, but the eSim for TMo doesn't register on the network. wifi-calling works for the eSim, but nothing else. In the Sim card settings, it detects an "unknown" carrier, whereas the GoogleFi (which doesn't work probably due to network lock) at least detected GoogleFi.
Edit:
So...whatever you do, don't listen to Help desk. They had me removing my eSim so that I can do the "scan qr" method even though I did the proper Convert to eSim method previously. The removal doesn't actually remove anything from the phone, so you can't "start over" hoping to try a different method. Even if it could, you disabled the physical sim, so you have no method of receiving the TMo verification codes needed to add a sim card to the phone. You literally lock yourself out of the network until they send you a new physical sim or reactivate your old sim
To reactivate the old sim, while forgoing the text message, is a 10min processs. Fortunately that's probably the most straight forward aspect. The 10min wait is to let the verification process timeout and it'll just activate.
I gotten it 5 days ago I really like the new features
What is esim?

Esim is where you can ditch the actual sim card and your phone have a built-in sim card manager to keep digital copies
I switched one of my other lines to my fold3 esim today (on TMO network) and been on with support for a while now they have no idea the issue. But it detects it as a T-Mobile network but it won't discover the number. It stays as unknown number. Can't use the data, calls or texts but it activated
Edit: after going back and forth with tech support, the issue has reversed itself. Now the esim has a number but no provider lol will keep this post updated
Edit 2: after more back and forth with some escalated executive support team they found the problem and fixed it. It's supposedly a bug in Samsung's esim that needs manual high level settings changed on TMOs end to fix on a per device basis

I'd like to say that after several days with physical sim and esim, I've zero problems. It just works. My only complaint is how voicemail is handled for the 2nd sim.
