hi i have a samsung galaxy s3 from sprint, rooted. My question is where/how do i find the "network & mobile network state" folder or file? the reason is cuz i would like to connect the phone to a prepaid or other carrier and i think deleting those files will allow me to do so, (PLEASE correct me if wrong)....
OR better question is how can i get the phone connected on a different carrier?
Can i or do i have to erase, change or clear any of the following; MEID, DEC, HEX#'s or IMEI & ICCID to do so? I Rooted the phone with a custom ROM (CM). Some say sprint will give me a certain number but my service was cut yrs ago so i doubt they would help being that i owe them $.. and is rooting same as unlocking?
THANK YOU

im not going to be of much help with most of that but,
you defiantly dont want to remove the imei or related items, or the phone wont work on any carrier.
if this is the phone you were using when you stopped paying them, it may be blacklisted, and wont work on any carrier.
best option would be to browse the s3 forums and see how others are switching carriers.
some phones its as simple as changing the sim, others require more steps such as carrier unlocking and possibly more depending on the situation. and in some instances you cant change to the carrier you want because the phone doesnt support the necessary bands.
Hello, I just bought a verizon Samsung Galaxy s7. I am a net10 customer, so to use the phone i purchased the byop kit and inserted the verizon compatible chip and then i go to register the phone with net10, and it says it cant do it, to contact customer service. So I called them and they said that for some reason the imei wont register manually, and that i have to call verizon and see if it was locked. So i called verizon and they said according to the imei i gave them it isnt locked, and that verizon doesnt even lock 4g lte devices. but no matter what i do i cannot get the phone to register with imei. I have even tried strait talk. Another thing to note is that on the verizon website, the s7 isnt listed as compatible device for a byop plan.
So theres no one i can call to have anything unlocked, i cant get my money back from net10, after i called net10 customer service back and told them that verizon said it wasnt locked, net10 CS then stated that the phone wasnt compatible on their network.
A verizon tech said he sometimes has problems registering phone imei's. He said sometimes it goes through, and sometimes you have to keep trying. I really have no clue of what type of process is happening here...
So, i took out the verizon compatible sim, and put in the att/unlocked gsm device sim and then registered that through net10. it actually went through, I now have a phone number and i have basic data, but i cannot send or receive mms. I used the APN settings i found somewhere on the internet for ATT network as they are the only ones that work so far..
The other problem i have is that my phone says the sim isnt from verizon, which im assuming i can just flash the "u" version of the rom to take care of? But am i hoping there is a way to make my phone work in their network so that i can use the intended sim card.
So with all that said I have a couple questions.
1. Why wont my phones imei register on the carrier networks?
2. If i cant get it to register on their networks, is there any way to at least get my mms working?
I find it very strange that no one else has had this problem. I cant find any information as to why the s7's arent part of the byop yet.
Thanks in Advance!
Does anyone have a definite solution to this problem? I've read many opinions but haven't run across a solution. I have a Samsung unlocked S9+ running official AT&T firmware and userdata but the carrier specific apps and features still don't work. The best infomation I've found is that the IMEI numbers of the unlocked devices are not in AT&T system so the features/apps won't work.
If this is the case, has anyone had any luck getting AT&T to register their IMEI and get the features working?
What worked for me and others (see the at&t fw thread) is to call or chat with AT&T and give them a imei from a carrier branded phone(with your sim in, though this might not be required). Tell them you are trying to get wifi calling to activate and it is failing at the provisioning step and they will input your imei and it will reprovision. Then pull your sim and put it into your s9/+ running at&t fw and it will allow volte, wifi calling and call protect to work (these are the only ones I use).
Good luck
I talked with someone in AT&T technical support and they remoted directly into my phone, reset all app defaults and network settings.. This of course didn't fix anything so they opened a trouble ticket. They told me my IMEI was in their system and was OK. Haven't heard back yet.
why not just flash ATT U firmware?
I'm running AT&T official U firmware G965USQS2ARF4. What just occurred to me was that I didn't do a factory reset before or after applying it via ODIN.

Yes your IMEI is in their system. But it's not an IMEI from a branded ATT phone. You have to have the IMEI from an ATT phone like others have said, and like i had to do or you will not get the features, no matter what firmware you flash. This has been discussed in many threads. You have to have ATT change your IMEI in their system.

Wont help unless you have a 965U or the IMEI from an ATT phone . ATT Features will not work on 965U1 IMEI. AT&T told me theses features wouldn't work on an unlocked phone and asked if i had the unlocked version. I told them no, it was an ATT phone i bought from Best Buy and it has an ATT logo (not the truth, got it from Samsung) and that i read in the forums that there were some issues with the S9 and that changing the IMEI fixed everyone's problems. I said i had my s8 here that everything works on and she said it's worth a shot to try and she changed mine in their system to the IMEI from my AT&T Branded S8 that i provided them. 965U1 has worked flawless ever since. All features work.

sounds about right.. i mean you can switch csc while on U1 depending on the sim card inserted but U1 isnt meznt to have all the carrier crap they need for the special features to work so u get the bare minimum..
while on U firmware, it seems the csc doesnt fully switch like they did on the S8 devices.. i tested this on my sim unlocked vzw s9+ with an att sim and a sprint sim and although data and calls worked,it stsyed on verizon bootani and bloat etc etc no matter what i did.. before on s8 devices after a reset it would have changed the boot ani,bloat and woulda had all the carrier features..
im also surprised they changed your imei lol.. i thought that was illegal lol.. i guess if the carrier does it then its fine haha

Hard to believe that they would just accept another IMEI and register it to your phone. I thought these were all unique numbers that couldn't be used on more than one device. How did that change affect the phone that originally had the branded IMEI?

Didnt affect original s8 i used at all. or the s9. I replaced the s8 with the s9 when it came out so i just used the sim out of the s8 when the s9 arrived. s8 is just a spare phone now. I asked the operator if this would disable the other phone that the IMEI came from and she said no. I put sim from s9 in s8 afterwards just to test and it worked fine. They arent changing the IMEI of your actual s9, it still shows your original IMEI in your phone settings. They are just using the IMEI you provided on their end. What is actually going on behind the scenes i dont know. Maybe somebody that works in carrier support or may just have knowledge on how this actually works could chime in. I'm guessing they just use the IMEI to activate the features, since the unlocked one isn't eligible. I saw a better explanation in one of the firmware threads, if i run across it i'll post the link.

I will reiterate what is said above and clarify my post. You aren't asking the support team to change your phones imei. I think as stated previously that is a forbidden/illegal maneuver. The support request is to change the imei which is active in the at&t system as only carrier branded phones are able to use certain at&t features.
If you have an old AT&T phone its imei can be used to "trick" at&t into activation/provisioning. Then you can put your sim into a U1 phone using at&t firmware and use carrier specific features.
Hopefully, this is easier to understand and clears up some of the confusion I may have introduced in my original reply.

I presume I can use the IMEI from another brand of working AT&T phone such as an iPhone 6S (in this case, my wife's)?

Another thought... Say I get an old Galaxy S6 which uses the same size Nano SIM as my S9+. I move my S9+ SIM to the S6, update it to the latest AT&T firmware and enable WIFI calling. If I then move my SIM back to my S9+, will the carrier features now work?

This is exactly what I'm doing. I use an older LG phone and the sim/IMEI then swap it to my u1 with AT&T fw after the device is provisioned.

I previously had an AT&T branded S8+ with the same SIM that I'm using in the unbranded S9+ but I guess I never provisioned (enabled) WIFI calling. Dunno.
The "trick" of giving them an IMEI from an ATT branded phone doesn't usually work any more, maybe it used to, years ago.
This is why I won't buy OnePlus phones any more. I love their devices, best bang for the buck on the market, but no amount of my fiddling would get ATT to recognize it and provision VoLTE... so no wifi calling, no HD calling... when you make a call, your data drops to 3G, etc...
My Essential, somehow was on their "BYOD" plan and so it would give me VoLTE and HD calling, but no wifi calling. No wifi calling is stupid, because you aren't using their network at that point, so why should they even care?

"maybe it used to, years ago"... That doesn't apply in this context does it as carrier features VOLTE and Wi-Fi calling weren't even in existence years ago. And I'm not sure you have to give them anything. The claim by some is that just provisioning the features with your SIM on a branded device is enough.

And as someone who has repeatedly tried it, it doesn't seem to work. You can give them an IMEI from another phone, but it usually doesn't work. Either the IMEI is "on their list", or from a phone that is on the BYOD list, or it isn't. It's not the phone's fault, it is that AT&T is kinda being dicks about this... They want you to buy their phones, because most people sign a contract to get the cheaper price, or use their NEXT financing to spread the costs out. That creates a barrier to exit for most customers and protects AT&T's revenue stream from monthly invoices.
While bringing your own device makes them just as much money from the monthly bill, it doesn't help them "retain customers by locking them into a contract", so they usually don't give you full functionality...
I have had a working SIM from an ATT branded phone that was properly provisioned, popped it into my other device, and VoLTE went away. I would call them up and give them the IMEI from the phone, or one that I know worked, and still no go. The one exception was the Essential, and that was because for whatever reason, Essential went to the effort to get it on their BYOD list.
Trust me, if it was easy, I would be doing it and buying OnePlus phones exclusively every 6 months and that would be the end of it. LOL
I recently purchased an open box Galaxy S10+ G975U. Phone was in excellent condition. Was told it was an unlocked phone from Verizon. Upon receiving it, it had ATT Splash Screen and Apps. Was trying to get it working on Page Plus, and MVNO of Verizon. After much effort between seller and Page Plus, we finally got just about everything right.
We switched it back to Verizon Splash and Apps. We got everything working or so we thought finally with some APN changes. However, after using it a day or two, I noticed that during a phone call, LTE would always drop to 1X, thus making MMS and Data usage unavailable. Page Plus Customer Service is not good, some are better than others, but I cannot seem to get the issue resolved.
I recently got rid of the Verizon from CSC just to see if it would help and switched to XAA/XAA/VZW. Thinking it would help and it has not. My Galaxy S8 that still works with the same Sim Card with LTE that works correctly as well during calls, has a CSC with TFN/TFN/XAA.
I do not have the ability to switch to Tracfone (TFN/TFN/XAA) but don't really think that is the issue as Page Plus uses VZW devices.
Does anyone have suggestions or an answer as to what could be the issue? I have collectively spent at least three full days of my life between customer support and reading through all the forums and posts.
Thank you in advance to anyone who replies or has knowledge that may help.

I have a Galaxy S20+ 5G and I recently ported my number over to ATT from Verizon and everything seemed to working fine with the exception of VM and few other things.

I've used different versions of the ATT user data file and no matter what I do the carrier software version on my phone still reads VZM. I know the flashing process worked as I now boot to a Samsung screen as opposed to the Verizon one. I'm sure I'm missing something but after 12 straight hours of trying to fix this I'm running out of things to try. Any help you can provide will be much appreciated.
PS I read something about the carrier info. being locked to the phone but the phone is definitely unlocked as it works for calls and texts using my ATT sim.
You can request the carrier not send you updates to that device. Disable on their end.
This is what I've been using for 2 years.

My bad... skim reading badly again
The AT&T update app is just as bad as the Verizon one.
AT&T bloatware sucks. I use their texting app, the rest is package blocked.
If your phone's running fast, stable and fulfilling its mission... let it be. AT&T updates can break your phone.
Yeah the factory reset just wasted time more than likely.
Not sure your variant's hardware is compatible with AT&T firmware. Carrier phones can have different hardware as speced by that carrier as the major carriers and Samsung are partnered to the bone.

So that's the problem I still don't have VM and the ATT tech support claims that it's because it's a Verizon provided phone and that they can't guarantee that all features will work which just seems like a cop out on their part. My wife has a iPhone 12 and everything works just fine for her and the rep claimed that Apple phones are easily interchangeable between carriers and that Androids always have problems which again seems like a BS explanation.

There's a way if that doesn't work. Anytime a tech tells you to do a factory reset for a settings or usage issue they are either inept, blowing you off or both.
