I have a Verizon Samsung Galaxy s3, I have moved it to a straight talk plan, as most of u know there service runs off AT&T and T-moble, Verizon hates AT&T and blocks data use on there network everything but E, What i am trying to find out is can I root my phone and flash a AT&T rom over my Verizon branded phone so it will unlock my 4G? I already have the AT&T sim card in the phone.

I don't think it's going to work. When you signed contract with VZ, they locked your phone to their network. After the contract expired, they will unlock your phone so you can use it on any carrier. If you're not under contract, you can check with Verizon to make sure your network is unlocked, from here on you can use your ATT sim card to register with ATT. Second method, you can search for how to unlock Verizon network and try it. (input a special dial code to access the network unlock hidden menu and unlock from here).Good luck and post back.

The hardware does not support LTE for AT&T. I'd you want LTE on AT&T, buy A GSM phone (or AT&T S3) and live your life. Flashing another carrier rom is not advised by any means on the Verizon S3. Best you'll get with our S3 is edge or 3G. Verizon doesn't hate AT&T, they're incompatible networks because AT&T uses GSM bands and Verizon uses CDMA bands. A small number of phones work across multiple carriers as far as LTE but that's because they have every band included in the phone (for example the iPhone 5S). Other phones on Verizon will only get edge or 3G.

Thats all I really wanted to know i guess, is if the hardware was the same in all samsung galaxy sIII, I am still a noob with smart phones, I thought the hardware was all the same just the firmware was branded to whatever comp. sells them, and with the GSM\CDMA the galaxy sIII runs both.

I am not under a contract anymore and the network is unlocked, I can make calls and get mms, also with the AT&T SIM card the phone says AT&T at the top of the screen all the time, just still boots as a Verizon.

OK, now I understand what you are looking for. It's not recommend to flash rom from one carrier to another, you could hurt your device. I thought you 're looking to move from VZ to ATT, but seems like you already done that (network unlocked), and now you just want to change the boot animation (Verizon logo during boot up). You should search for VERIZON modified rooted stock rom or custom rom with bootanimation kernel support. Once you installed custom rom/kernel you should able to pick and chose from many bootanimation liking to your taste..and change greeting, display etc...

This is very very Dangerous because you can destroy EFS-Partition (IMEI, etc) so you cannot call or surf anymore!!!
Don't do something like that!

I got the sprint version to work with other carriers, even Verizon! I haven't figured out how to make MMS work on Verizon, but I do get LTE most places. I didn't have to activate on Sprint and didn't have to go to the store.
Here are my steps:
1. Activate device on free plan on Ringplus.net
2. Call Sprint at 1-888-211-4727. Go thgrough the prompts until you reach someone. Tell them that you have a Sprint phone that is not active on Sprint and you would like to sim unlock the phone, aka domestic SIM unlock.
3. Restart your phone and give it a few minutes to unlock. It will most likely reset itself.
4. Pop in a new SIM card and see if it works.
Quick question are you rooted?

Did you get at&t working
I am not sure if you have to activate it to Ringplus to get it unlocked from Sprint.
It should be GSM unlocked by Sprint directly, no need to activate it with RingPlus if you don't want to use it with Sprint network.
All carriers will SIM unlock devices that are not activated and paid for or out of contact.
Hardware may limit some 4G functionality with different carriers since each carrier uses different frequency ranges.

The sprint unlock is through a signal they send to the phone. It will not work if it's not on an active line, unless you take it in to the store. That was my experience at least, and I've seem other posts saying the same.
I didn't have an AT&T sim to check
Hello once again. I received 2 sprint s5's from my mom when she upgraded to S6's. I called straightalk asked if I could activate, no, called sprint prepaid, no!! I currently habe straightalk, and am willing to change to sprint amd get a contract, However I have sketchy service at my house, and really wanna test it out first. My question is whoop can activate these phones here in the SE US. Boost? Virgin mobile? I'm fairly granular with flashing and stuff and can read and follow directions. I do see a SIM unlock for non USA mostly, but would try it if all else fails. Right new the phone are factory reset on 5.0 lollipop. I can do what ever needed to get them SIM unlocked so I can activate for another service or just provide me with another provider that will activate. Amy help appreciated.

Youll have to pay for domestic gsm sim unlock,then adjust your apn to new carrier for data. Idoneapps unlocks these phones.
Sooooo
Ok thanks. So if its sim unlocked, and apn adjusted, I just pop sim in and I should be good. Even ifstraightalk tells me I can't use this phone?

Correct.
P.s. you also may have to enable some bands,depending on what carrier also.there are tutorials on that.
You can activate Sprint phones on Ting very inexpensively. Ting uses the Sprint network with CDMA phones.
Ting will check with Sprint to be sure the phones are out of contract and no balance owed.
S5 sm900g wifi popup
Thanks for the replies guys. Ting users CDMA? Mine is GSM, i found the threads about unlocking it. Hopefully i can get it. And one more question, i am constantly getting a pip up saying turning WiFi on will disable Hotspot. Ive done a hard reset, and back on official 5.0 lollipop. Not rooted yet but reading up on it before starting. This S5 lollipop is a bit diff from S3 KK. Thanks for any help or tips.
Sprint has a 14 day trial period. I was running around with 2 phones testing out sprint when I first got it.

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 flashed my S7 (930P) to a 930U following these instructions: https://www.youtube.com/watch?v=y0eye-zDOtQ
When I slap my XM sim in my S7, it tells me none detected. The sim is good, I can put it back in the e5 I snagged and it gets coverage immediately. I've tried flashing the modem with the VZW image and am pulling down the 930VC/CCT image now so I can try the Xfinity modem file in case that is the ticket.
If it's not, I'm not sure what my next step is. Any recommendations?
Turns out I'm not thinking straight. Checking the modem file now.
No luck
The device wasn't unlocked and I had the impression the U firmware would release that lock. Not true, still had to get Sprint to unlock.
@eskaryo
I have a sim unlocked Sprint S7 (g930p) on Android 8.0. And when I put in my active xfinity sim almost everything works. Data works, incoming and outgoing calls and texts work. But it won't switch out of roaming and all MMS including group text won't work. So do I just need to flash the firmware you mentioned to get everything working right? And can you flash it on a locked bootloader (which I believe this sprint s7 has)? If so can you confirm the exact firmware I need? Thank you!
I have the same problems with Xfinity service on my s7. This is most likely due to APN settings though I don't know for sure. Sorry I couldn't be more help.
