Looking into buying an unlocked s9+ to get activated on the sprint network. I have been doing a lot of reading and was wondering will there be any features I lose if i keep the unlocked firmware. I read that you can flash it to the sprint firmware, will that fix any issues with the features that are locked on the sprint network due to having an unlocked phone. thanks for the help y'all

So based on your post you can flash to carrier firmware and not lose any features for any service. This is good info should be sticky somewhere.

That wasn't really the point of my post I linked. And it isn't entirely true, especially with AT&T. I was describing what features will work on the basic U1/unlocked firmware on phones sold by Samsung directly as "Factory Unlocked".

You keep visual voicemail and Wi-Fi calling. I don't believe they offer any other services (yet) that you would lose on U1. If they do, they've got to be very minor. Given that Sprint has the worst bloat of all the carriers, I'd recommend you keep the device as-is.

Hi guys, anybody here using the unlocked version of LG G6? I preordered mine off BH Photo Video and it arrived yesterday.
Was browing the threads and forums and haven't seen any regarding the unlocked version. My carrier is AT&T but I hate carrier phones since my experience with AT&T LG G5.
I saw lots of threads about how to access the hidden menu and stuff and tried it myself but didn't work so I was hoping some of you here uses the unlocked version and knows how to do that stuff.
Thanks!

Nope. LG did something stupid again like they did with the G4. They made the us cellular version and us unlocked version the exact same model number. I thought they had learned because with the G5 they differentiated the model number for the us unlocked version, but they went back to old habits I guess. So there are two variants of the us997:
US997: US cellular
US997: USA unlocked variant

No sorry, don't have the device so can't test. Maybe try putting a 0 in front of behind the 997 though, not sure. I'm guessing they wanted to differentiate the access code for the two different software versions but not sure. The code should be what was posted just different would be the 997 part.

Not sure then
I have read through many threads and I cannot find a direct answer. As it is stated in the title I have the Galaxy unlocked s9+that I bought from Samsung. I am currently on AT & T network because T-Mobile is terrible here in North Carolina where I am currently living. Can I flash ATT firmware on this unlocked version of the S9 plus and use Wi-Fi calling and volte? If there is a definite yes to this question then I will try to find the ATT firmware the flash on this phone.

The answer is yes.
The firmware can be found pretty easy by looking in the forums or by looking on sammobile.com
Also, make sure you are flashing the same version of firmware. So if your device last digits are ARF4, then you want to flash the ARF4 AT&T firmware.
I have a question for this unlocked version from samsung.com. i I use it with Tmobile is the wifi calling, Volte, will work out of the box? or i have to do the same thing as flashing tmobile firmware? and also if I flash do i have to root? TIA. and also if there is already a thread for this question kindly post the link.

Yes if you use it on T mobile, the wifi, Volte will work out of the box. I was on T Mobile but because of coverage I had to switch to Att.

Since this is an unlocked phone not purchased from ATT, WiFi calling and other features wont work even on a regular post pay account. I had to call ATT and give them my IMEI from my previous ATT branded s8+ before wifi calling and smart caller ID and other features would work. I told them it was an ATT phone that i purchased at Best Buy and i read about WiFi calling problem in a forum and that using a different IMEI worked for others. The tech said it's worth a try and she changed it and ive been good to go ever since. I fumbled around the question of "is this an unlocked phone?" i said no, it has ATT logo (it does at boot, but not on the back lol) and i purchased it for ATT. That was good enough for them.
Many others with unlocked U1 phones have done the same thing and ATT has changed IMEI on their side. It doesnt change your phones physical IMEI, just their end. I saw a post where one operator said they wouldnt or couldnt do that. If they tell you no, call back you'll likely get a different person and they might change it. Main thing is you have to have an IMEI from an ATT branded phone that supports the same features (s8,s7,s6, etc) Luckily for me i have a like new s8+. It's worth much more than what they offer for trade in so i kept it. Glad i did.
Yes, I saw those posts as well but currently I do not have an ATT branded phone. So, I went and put the unlocked firmware back on the phone and I will just keep it the way it is. If the new iPhone that is coming out has the T-Mobile band 71, I probably will jump back to the iPhone. This was my first Android in about 4 years. I am kind of disappointed that it won't work.
Wifi calling is enabled for Verizon (go to phone settings to enable). I am sure there
are other changes. Update G965U1UEU3ARH7.

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. 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..

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.

Carrier is not relevant in this particular matter as the hardware and software is all the same. The only difference is the carrier apps, carrier branding and carrier tweaks/configurations to the OS (band settings, etc).
There is no updates at all. It's a pure waiting game. If they have something they will tell us, if they don't it means they don't. It's a pure game of 100% patience on our part.
