I'm leaving Sprint for T Mobile with my S9+ SM-G965U. Will I need to flash new firmware specific to T Mobile other than swapping SIMs? I'm referring to Wifi Calling, visual voicemail and other useful features. Does T Mobile load up the bloatware like Sprint? Thanks.

TMobiles firmware will download when you install the TMO Sim card.

In order to get the full functionality of my sprint phone on Tmobile I needed to flash the t-mobile firmware. If it was as simple as switching sim cards (after putting the tmobile sim into my phone) I should have had access to all features/services. In order to get video calling (as well as better signal strength and stability) this required me to flash the carrier specific firmware for Tmobile.
Imho it's a bit more then just "the firmware is downloaded onto the phone" by swapping the sim card. From reading on the subject (and from my own experiences) when the sim card is changed the settings/configurations that reside on the sim card are applied to the phone. This may also cause the phone to restart and apply carrier specific configurations that reside within the firmware are applied.
Your can most use the phone just fine with the sprint firmware installed, but certain Tmobile features might not work 100%. Things like the shakn/stir, video calling and perhaps signal configurations will most likely (I know video calling and signal enhancements did on mine) require the Tmobile firmware.
Personally I would suggest flashing the U1 firmware, factory resetting the phone and flashing the Tmobile firmware. That is what I did and I have had nothing but great results on the Tmobile network.
IMHO I noticed less bloatware with the Tmobile firmware then with Sprint's firmware

I have a Verizon branded Samsung galaxy s4 that I am currently using on T Mobile. I put my tmobile sim in it and it works just fine after I changed the APN settings to the T mobile settings so I would get the data, MMS and picture messaging, et cetera et cetera. However I recently noticed that Verizon just released a major firmware update for our phones that will update it from the most current version that we all have: Android version 4.2.2 with firmware/baseband:I545VRUAM(E)7 TO Android 4.3= with firmware/baseband :I545VRUAM(J)7. anyways, book this new firmware... Allegedly, once it is applied not only does it update the android version,..but it is supposed to unlock all of the of the available AWS - LTE bands and data technologies that a lot of other carriers use for their high speed data. So effectively once the update date is applied... instead of getting 3G or H+ (HSPAP), we should effectively be getting 4G and or LTE in a lot of areas using T-mobile on that phone. I have not yet downloaded and applied the update to my phone because I'm a bit hesitant. My phone is working fine now and the maximum data speed I get is the H plus, however I would love to be able to get the other bands on my phone that this update offers in some places. I'm just a bit concerned that I wonder if when the new firmware update is put on the phone will it possibly put a restriction or sim card lock on the phone that was never there before? Effectively not allowing me to use the tmobile sim card in the Verizon Galaxy phone any longer? I just wanted to reach out to other people in the same situation to see what firmware version u guys are using thats allowing use of a tmobile sim card, and anyone who has successfully done the new firmware "MJ7" 4.3 ... update and are still able to use the tmobile (or other carriers sim cards) in the phone with no new negative issues or restrictions or locks. Thanks so much I'd appreciate any feedback. -Rob

I'm on AT&T,but just bought a rooted S4 off someone with a Verizon ROM on it. Would I just need to flash a AT&T ROM for the S4 to be able to get the SIM card to work with AT&T?
Any help appreciated.
Same here. My friend gave me his S4 today and it is Verizon and running on the stock ROM. However, I am on AT&T. From what I hear this phone comes factory unlocked so you just plug in the SIM and it should be okay. Is there anything else that I need to know if I want to use this phone as my main?

After a brief visit with AT&T today, they installed a SIM card from their carrier into my phone, but it would not get speeds grater than EDGE at the time. 3G may have been possible, but it didn't see it right away. Also, they had to update the APN settings in the Settings -> More settings -> Mobile networks -> Access Point Names. Lastly, after searching the internet, Verizon carrier locks the GSM in the states. In other words, they make it so you can use GSM OUTSIDE the US but not allow AT&T or T-Mobile SIMS to be used in their devices. This is a carrier lock, not SIM lock, so they can get around the whole "well, our phones are sold SIM unlocked" bs. After calling a level two tech support, he told me that there is no such thing as a carrier lock or SIM lock, and he could not give me a code. The phone was able to make a voice call and send a normal text, but data sucked.

Sorry to disagree, but my SCH-i545 works on the AT&T network with an AT&T SIM installed.
I only get Edge because that's the only band that VZ and AT&T has in common in this area. Swapping out a SIM isn't going to fix that.
What you're finding about GSM locks applies to pre-LTE phones. The LTE phones are not SIM locked, aren't carrier locked. Period.
Sorry for the noob question, just got the unlocked version of the S9+. I have build G965U1UES2ARF4. Read some stuff on other forums, thought I had it figured out, but got confused as I read more.
I would like to enable Volte/Wi-Fi Calling. I understand I have to flash AT&T firmware via Odin. I am not clear on what files and how to do it on Odin. Any help would be appreciated.
Also, if I flash to AT&T, do I lose whatever comes with my current ARF4 build? For example, I have FM radio enabled. Do I lose that because I am going over to the AT&T firmware where I think it is disabled? Is my phone no longer unlocked? Do I get bloatware?
Last question, when I flash, is it the same as a factory reset?
Any help appreciated. Thanks.

You will not able to use wifi or volte on an unlocked Galaxy s9, even if you install the att firmware, I tried. Some have reported if you have an att branded phone with sim give that IMEI number to att support and then transfer the sim to the Galaxy and it may work, I have not tried it. Wifi and Volte will work with t mobile with no problems, I have not tried Verizon.
I have an unlocked variant on Verizon. With their firmware, VOLTE and Wi-Fi calling will work, but not video calling.
Wifi calling will not work on unlocked version with Verizon VoLTE will work

There is a hack for that which I use: Place your line's SIM in a real Verizon device. Leave it in long enough that the VZW website sees the line as the new IMEI and device model (should only take a couple minutes). Go into Service Blocks and remove the block on Video Calling. Put the SIM back in the original device). Voila. You've got Video Calling.
The system doesn't care to check once the line is activated. But if it's activated with a U1 device, it turns that block on. If you use this hack and turn the block off, they never check.

I went to the AT&T store the other day and they already had the IMEI from my Galaxy. So I wonder if I switch from an AT&T branded phone back to the Galaxy that the IMEI number of the Galaxy will just re-register.

It will. But it's more manual. Verizon will pick up the new IMEI automatically. My understanding is that AT&T will require a call in to support while the SIM is in the real AT&T device. You ask them to associate your line with the new IMEI while it is still in the genuine device. Once that's done, you can move the SIM to the device you really want to use.

Thanks. One concern is that Wifi calling is nowhere located on my unlocked Galaxy. I was hoping it would be disabled somewhere but it's nowhere to be found. Do you know once I pop my SIM back in if a WiFi calling option will just appear somewhere in the settings?

I wish I could help on that. With Verizon, the menu is there in the firmware at all times. As is video calling. Maybe AT&T hides it until the provisioning checks out. I don't know.
Volte not working
I have purchased s9 pluse from canada and now i am in india and volte services r not working can any tell me what do.
Wifi calling is enabled for Verizon (go to phone settings to enable). I am sure there

Yes, and Secure Wi-Fi has now been added. I think it previously existed only on the European firmwares. Now we get it, too.
Any way to see if AT&T Wifi Calling will work as I do not see the option in Settings? I have US Unlocked GS9 on AT&T
If I flash this U1 for my ATT phone (running full Tmobile firmware now),
will I have Wifi calling with Tmobile? Or Wifi calling only works with Verizon with U1

Despite what the websites like to post, there really isn't a VZW U1 and an ATT U1. There's just XAA U1. You'll get Wi-Fi Calling on every carrier with it now, except for ATT.

Reading up on it (short summary) this is because AT&T uses a database of IMEI numbers to provision WiFi calling and VoLTE. Since our IMEI numbers from our phones are not in that database we won't be able to use WiFi calling or VoLTE.
Makes sense but is ridiculous for AT&T to restrict it. Has anyone ever called to ask to have thier Unlocked IMEI added to this "list" so that these features will work? Seems like it is a disadvantage for AT&T if it works for TMo and now Verizon but not AT&T...?
Just curious...

It's odd for sure. Verizon has always had VoLTE on unlocked too. At least since the S7. Probably before that. ATT has never felt the need to change the policy.

Who can say if it's disadvantageous or not, for all we know it might be the technology differences between the networks. Also it does make sense... having specific IMEI numbers known to connect to carrier specific services like wifi calling and VoLTE ensures that everything works. It doesn't make it convenient for us and I will admit it would be nice to have the features.. but for calling via wifi there are options.
Personally I use pbx in a flash and bria softphone. With the right VoIP provider it's a good setup and doesn't break the bank at all. I haven't even spent more then 5 bucks maybe in a month. For me this is better then wifi calling and I don't have any problems.
As for adding our IMEI to that database I tried inquiring about it, but I do recall reading where some people may have had luck in doing this. I suspect it may require a bit of luck and/or perserveriance after my last discussion with AT&T customer service.
I explained the situation and what needed to be done while being placed on hold a few times. As the call continued I tried to be patient with the person I spoke too, but I admit it is not easy when he is saying that just because I see H data speed that it's actually VoLTE. When I mentioned the speed test and how it was H data speed (and that H data speeds are not VoLTE) he was saying that H data speeds were like blazing fast compared to LTE..
I had to politely finish the call before I either started to laugh or feel sorry for that rep.

In my case I tried to be patient with the person I spoke too. After waiting on hold a few times the representative tried to say everything was normal.. and then proceeded but to say that just because I see H+ speed that it's actually VoLTE.

The only thing I've seen some people do successfully to get VoLTE working on an unbranded unlocked device is to have AT&T provision a SIM card to an IMEI of a phone that is AT&T branded and capable of VoLTE. Then use that SIM card on the unbranded unlocked device.

Hd voice always worked on unlocked for Verizon. Wifi calling is found in the phone app's settings.
I flashed G965U1UES3ARI1 for XAA to SM-G965U1 and I can't find settings for Wifi calling. Are they visible or just built in and assumed to be there?

No problem. You're not the first person to look for it in the wrong place. U1 builds always place the setting there. So they stayed consistent doing it this way.
Since the Galaxy S6 Edge days I've been getting AT&T branded Samsung phones. This time around due to initial perks of a trade in were better for the unlocked version of S23U, I went ahead and pre-ordered the unlocked version. Are there any drawbacks anyone has experienced with the unlocked version that would warrant me to cancel the order? Are there any AT&T features such as visual voicemail, personal hotspot or HD voice that isn't compatible with the unlocked, non carrier version? Any help would be appreciated as i believe I can still cancel the order.
Thank you.
With an unlocked phone, you cant call. But if you add a sim card into it you can do anything such as mobile data, call, hotspot, etc. An unlocked phone can work on any carrier. But it is still the same thing as an at&t version unless you add the sim card in it.
So I assumed if i insert my AT&T simcard it'll work just like an AT&T phone?

That's what I have done for every phone I have had since the S7 Edge on T-Mobile. Still using the same simcard since I started out with the (S7 Edge), then Note 8, S20U, S22U and now S23U and has worked fine with T-Mobile but without the carrier bloat. The only downside is Unlocked versions always get the updates last.
You can always flash U (carrier firmware) that is bit different from from U1 (factory unlocked) firmware. This way you'll get exactly the same experience as for the phone of any carrier directly. You can always switch back and forth with data wipe.

First time Sammy user here, so possibly a stupid question but... from my search it appears that other than carrier bloatware you don't loose anything by going to U1 firmware and possibly gain faster updates. Is that a correct? Seems to be the case for WiFi calling but what about ATT wifi hotspots for example?
Unlocked phones were useful for sticking local SIMs in them for international travel but with the new international plans pricing is actually reasonable so it is not worth the hassle.

I was in the same situation as you, and ordered the Unlocked version this time instead of the AT&T version. I am happy to report that everything is working. Visual Voicemail (Samsungs App), Personal Hotspot (aka Mobile Hotspot), HD Voice (VoLTE), and WiFi Calling.
