So, I've recently rooted and unlocked my device and I wanted to know if I can bring it to another carrier and still get data.? I'm using the LS991 Sprint version. I also wanted to know if there are any good CDMA Workshop alternatives; it's really expensive and I'm only gonna be using on a few devices.

So you rooted (doesn't really matter with respect to carrier support) and you unlocked it (that's what matters with respect to carrier support) - so you put in a SIM card for the carrier you want, set the APN data (use Shortcut Master if needed, there's a version specifically modded for the LS991 directly available in my post HERE - might be a good idea to read that post as well since that's what I did myself.
Worse comes to worse if you have no luck because you unlocked your LS991, consider installing the global LS991 ROM (whether it's Lollipop ZV6 or Marshmallow ZV9 or ZVA - if you install ZVB you can never go back to anything prior so be aware of that) which will work much better for other carriers than using the unlock mod so many of us have done in the past.
Hindsight being what it is, if I knew about the global ROM when I got this G4 recently I wouldn't have mucked around with all the unlocking crap and the carrier partition at all for any reason because just installing the global ROM (or modifying build.prop to allow for global unlocked operation) is way more useful and less damaging to the phone. Modifying the build.prop isn't necessarily a cakewalk but, since someone else has already done it for others and posted the global ROM(s) for Lollipop and Marshmallow (as .img files you flash using the Send_Command.exe/dd method) it's really not a big thing anymore.
If you muck up flashing an .img file you can typically just use LGUP and a TOT file to get things working again so it's relatively safe overall, but if you muck up the unlock and trash the carrier partition content the phone will end up being pretty much useless unless you have that information safely backed up someplace (I'd say multiple backups in multiple locations, to be honest).
Anyway, if you truly want the phone to be capable of working on other carriers, my suggestion is go for the global ROM but that's just my own personal opinion on the matter. I'm using tabp0le's MellowMallow ZVB global ROM on my LS991 and T-Mobile LTE works just fine for me, for the record. It did take a little work - I wrote about how I got the full phone/data working in that post with Shortcut Master - but it does work.
Thanks for the help!
One last question, how did you get other carriers to let you activate the phone? Everytime I try they ask me imei then tell me my phone won't work on their network.
Well I've had service with T-Mobile in the past (not currently but will again soon), I have a bunch of T-Mobile microSIM cards because whenever they put the SIM card activation kits on sale for $.99 or sometimes even free (rare but it happens) I usually grab 3 at a time so I have 'em around for testing purposes. T-Mobile doesn't require me to provide any info to them, and even if I go to their website right now and input my IMEI number it'll say it's not recognized, etc but it's not relevant: it works, and that's what matters.
Most carriers don't actually require you to provide the IMEI for any reason as long as you can get one of their microSIM cards (or nanoSIM with adapter) and then get service without having to contact them. T-Mobile is somewhat unique in that process I suppose. With this SIM card I have (it's never been activated) I can go to their website and sign up for service right now and it'll be active in 10 minutes or less, sometimes when I've activated service (it's prepaid so I don't necessarily keep it month to month, sometimes I choose some other service for testing) it's done before I even sign out of their website, like 30 seconds or less and wham, the phone beeps telling me service is working.
So, the advice is: get a SIM card for the phone from the carrier you're interested in and go from there, not sure what else to suggest honestly.

You good sir are a god among men, phone and data are working like a charm. Now I can tell sprint to go **** themselves!
glad it worked for you. MY experiences with ls991, i am using it nvmode. zv6 rooted works for me with cdma data. but data doesnt work with zv9 or zva. global rom doesnt work unless, I edit build.prop target carrier to SPR . it is open to use it as global mode. I am using it in cdma nv mode.. not with any sim..

so in my case i use att on ls991. my build prop is ruim,sim i believe. now does that sound rite for gsm?
also another cdma workshop alt if qpst i used that one to rebuild my g2 a few years back

Ruim is basically used when it comes to cdma sim card.
"Removable User Identity Module (R-UIM) is a card developed for cdmaOne/CDMA2000 ("CDMA") handsets that extends the GSM SIM card to CDMA phones and networks. To work in CDMA networks, the R-UIM contains an early version of the CSIM application."
Your is at&t 4g gsm card. [emoji4]
Check your build.prop and search for
ro.build.target_operator: OPEN
Most probably for global mode open works
For making it work on cdma nv, i have set it to SPR
You can tweak with it by changing to options, it will also change signal bar and 4g symbol like at&t
These will show a Standered international 4G data icon for 3G/HSPA+ and LTE for LTE.
ro.build.target_county: CA
ro.build.target_operator: TLS
These will show a standered international 3G data Icon for 3G/HSPA+ and 4G for LTE (Messes up settings menu pretty bad)
ro.build.target_county: SK
ro.build.target_operator: SKT
If you want the AT&T 4G and 4G LTE Icons.
ro.build.target_county: US
ro.build.target_operator: ATT

My fav cdma tools are qpst, cdma workshop, dfs, revskill and bit advance is qxdm All are freely available. I cant say which one is best hahah. Trust me for me, all of them worked at some instance when i was stuck. Revskill is great with htc finding spc. Though i used dfs mostly.

Hi guys, I bought a used Note 9. The seller assured me it was gotten through TMobile and when I look at the package it came with, it has T-Mobile items in it
However apparently he inserted an ATT sim in it which apparently wiped the OS and made it AT&T. I have never heard about this sim profiling before. Right now, I cannot recieve SMS despite using the correct APN settings
What I want to do now, because I have no access to a TMobile sim is to try and install over this ROM with a TMobile ROM. How can I do this?
I was able to use ODIN in conjuction with N960USQU4ETF3_N960UOYN4ETF3_TMB which I got from Sammobile but the phone still has AT&T software instead of defaulting to TMobile. Why is this? It still acts like an AT&T phone despite me flashing over the OS
Try to look in here
https://forum.xda-developers.com/ga...-firmware-att-vzw-tmo-spr-usc-t3837086/page11
I apologize if this has been addressed elsewhere already, but I've been hopping all around the forums the last few days without any luck of finding something that addresses my particular situation (and I apologize if this' the wrong place for this too)...
Phone info:
Unlocked Samsung Galaxy Note 9, 512gb, bought off Amazon.
Model # is SM-N960U
Android 8.1.0
Verizon Branded
It came with a Verizon SIM card, but I already have a Sprint SIM card.
My situation: I have a Sprint branded Samsung Galaxy Note 9, it got damaged, but I didn't want to upgrade to a newer model (for reasons not relevant to this) and for $200 more than the repair costs, I was able to buy the same phone, but the 512gb version...
...So I did.
However, after activating it, which means putting my Sprint SIM card in it, and following all the steps with Sprint, I could receive calls and text-only SMS messages, but I could not get my mobile data to work on the phone and decided to blame the fact that it is Verizon branded* for this
*Sprint Customer Service kept saying I need to reset the PRL, among other things, like I would on a Sprint branded Note 9, but you can't do any of that on one that's Verizon branded; the options/menu in the settings is different
...So, this led me to downloading:
Odin3 v3.14
Sprint Branded Firmware from Updato: https://updato.com/download-samsung-galaxy-note9-firmware/spr/
...Specifically, I downloaded the one dated October 29, 2018 on Updato since it seemed like the closest to what was on the phone...
...I then turned on USB debugging through the Developer Options (could not find or gain access to the OEM Unlock option though, no matter what I tried, on my phone), rebooted my phone into Download Mode, but did not "proceed" as it were, plugged my phone into my laptop, Open Odin as an Administrator, put the firmware files (i.e., BL, AP, CP, and CSC) in their respective places...
...I picked the CSC, not the Home CSC, for the CSC spot in Odin, in case you were wondering...
...and finally pressed Vol Up to "Proceed," as it were, into Download Mode and clicked start on Odin, which did its thing...
...And, after a bit, I got a green "Pass" in Odin and my phone was now in Recovery Mode, since I left the "Auto Reboot" checked in Odin...
So, I selected "Reboot Now" and... I got the Verizon Splash screen and it was like nothing had happened to the phone... Except... My Sprint Mobile Data now works on the phone...
Now, I could technically live with this and begin transferring my data from my old Sprint branded Note 9 to this new Verizon branded one, now that the mobile data works, but there are WAY to many smaller annoyances with the new phone (like how one updates the PRL) that I was hoping to fix by rebranding it as a Sprint Note 9 via Odin
...So, any advice on what I should do?
Also, I'm not married to Oreo either, I just went with that because it is what the new phone has on it as my old phone is running Android 10 with One UI 2.5... And I figured I'd update the new phone to that, via OTA, once it was rebranded too...
Just clarify:
-Is "rebranding" possible with my Note 9?
-What can I do to make it happen or what have I done that I could do differently to make it happen?
I appear to be in one of those samsung lock horror stories. I purchased a paid off verizon s21 ultra that was suppose to be unlocked but after i put my tmobile sim into it works for 5 minutes perfectly then an error pops up saying unable to change carrier call verizon customer support. So i did long story short i got no where. So i filed an FCC complaint and got in contact with a verizon executive and he got in contact with who i bought the phone from and they provided all the paperwork proving it was paid off and he reprocessed the unlock request and said it will now for sure be unlocked and it didnt unlock so i contacted samsung like he said for me to do if it didnt so i did and they told me to wait 48 hours for it to process. 48 hours later guess what its still not unlocked so i call samsung back and they said verizon still hasnt released it supposedly and there is nothing they can do and i need to go back to verizon. Im stuck in an endless loop of verizon executives telling me to call samsung and samsung telling me to call verizon.
What is there left for me to do now? This is stupid why is it not unlocking... The only thing that i can think is left is that the phone is flashed with stock firmware and not verizon firmware to remove the bloatware. But that seems like it shouldnt matter. Also the phone never asks for an unlock code it just says call verizon customer service.
It's more a Verizon lock horror, not Samsung.
Flashing other FW won't solve your issue.

First, did you verify that the unit is paid off?
Second, do you know anyone that has verizon?
Don't know if it will work, but I would try flashing the unit back to stock Verizon firmware and finding someone who has a verizon sim card.
Verizon units kind of unlock on their own. It is troubleshooting I would try because I do not believe the unit will unlock on U1 software on its own. Once it can get unlocked then flash back.
I suggest someone who has a verizon active SIM as it may help in it unlocking even though you can connect through WIFI

The verizon executative said it was guaranteed paid off and he unlocked it remotely again. But it does have u1 firmware on it im guessing i need to use frija and download the vzw firmware? And will another unlock request need to be processed again? And none of my friends have verizon due to how much of a ripoff they are lmao but i can have another verizon demo sim put in at another verizon store. I feel like i would have to file anpther fcc complaint just to talk to another verizon executive.

I believe for it to be unlocked or at least go through the process, the verizon U package is what I would flash, but you may be in a little bit of a issue if you don't have a verizon SIM on hand, even if not activated.
There are multiple ways to get it to flash back to U. I would use a patched ODIN and just flash the appropriate files from somewhere like samfw.com
If he sent out the remote unlock, it is very possible that once you flash back to U verizon package and connect to WIFI and go through the setup process etc. It may just unlock on its own. If you do not have a Verizon SIM card, leave your SIM out of the phone while going through the initial setup. You will need WIFI.
I would start with a clean flash just to be safe.

You literally quoted the answer
Verizon firmware has an app called "Network Unlock". Perhaps at the 60 day mark, the phone automatically unlocks. However, if on the unlocked U1 firmware, there is no framework to remove the lock. It'd be interesting to see exactly how the Verizon unlock process works.

It is somehow tied into their U package software and I am assuming unlocks it at the modem level in background processes. It's like the "signal" they send out can only be detected on their U package. I've seen it many times where Verizon phones automatically unlock themselves when restored to original package from U1.

I can confirm this works on my s21+ that was on verizon network, and was supposedly networked unlocked. Service carrier software said vzw/vzw, vzw/vzw. Tried to switch to tmobile with no luck with sim card swap. 5 minutes, error message about cannot which carriers, please call Verizon. Was on SM-996U1. So I tried to flash to SM-996U1 TMB, then SM-996U1 VZW, then, SM-996U1 XAA. No luck. Then I flashed, hesitantly, with SM-996U VZW . I thought that would put all verizons bloatware on it. Reseted phone and it did put all verizon bloatware on it. Then the magic! I installed my new tmobile sim, and a message appeared and asked if I wished to switch carriers. YES!!! phone rebooted to tmobiles network with no verizon errors. I checked service carrier software and it was TMB/TMB, VZW/VZW. I flashed phone again to SM-996U1 XAA. I rebooted and service carrier software was TMB/TMB, TMB/VZW! I then checked for software update, took update, and all it good! Thanks for all the information here. Took me days to find it and understand it and try it!!
Hi, folks. I am facing the same issue with my S21 5G (SM-G991U). I am also told that the phone paid off and clean. I am not sure what version I am on currently. I have tried SamKey, but that didn't work. Any help would be appreciated. Thank you in advance.

From my experience, Verizon phones will not unlock unless on the U package, the U1 never allows the unlock to be processed.

It does not boot up with Verizon but it does have a few Verizon apps included (it has Call Filter and Digital Secure) installed. The current version of the software is G991USQS6EWD5. Service provider version is SQOMC_SM-G991U_OYN_SPR_13_0020 SPR/SPR,SPR/VZW.

Are you using this phone with Verizon service? From info you provided, your phone thinks you are using Sprint. It's a SPR CSC. You need to change the CSC to VZW. You need to bring the phone back to it's original state for any attempt of the unlock "processing".
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).
