[Q] Does anyone know if an Unlocked Note 4 can do Wifi Calling on T-Mobile?

Title says it all. I'm looking to buy a Note 4 but I need wifi calling. Do I need a locked T-mobile one or can I get any unlocked phone?

It would need a TMOBILE ROM. Also unlocked bootloader

In order to have wifi calling you need the following:
1: Tmobile branded phone N910T model or any other tmobile smartphone.
2: You need to be on the Tmobile network using a tmobile sim card.
3: You need to use Tmobile stock firmwares or Tmobile custom roms.
You don't need to have an unlocked phone, wifi calling will work whether
your phone is locked to Tmobile or sim unlocked for other carriers.
Wifi calling WON'T work on international Note 4 unlocked or locked phones
regardless of the network, carrier or sim card you might be using.
Good luck!

Thanks for the quick responses!

Why cant the international note 4 with tmobile custom rom use wifi caling? I had the international note 3 and it worked.

I've been searching for a thread to talk about this on.
I just recently purchased an SM-N910T from rent a center. It's a t-mobile phone with a wacky RAC rom. Can I put a stock t-mobile rom on it to enable wifi calling with my t-mobile sim card?

Got my new phone factory unlocked 5.1.1 and native tethering works!

OK so this is kind of weird. I just took ownership of my factory unlocked AT&T Samsung galaxy S5. I was dismayed to find when i opened the box and booted it up that it actually had the latest version of lollipop 5.1.1. What is very interesting however is I am in Canada it once I realized that I will not be able to root this device, I decided for fun to turn on the Wi-Fi hotspot and see if it would work and to my surprise and excitement the Wi-Fi hotspot worked with my Sim card for my Canadian carrier. So I don't know if this was a special version that was put out because this came factory sealed in the box it was a factory unlocked model the tethering was unlocked as well. It does have the AT&T bloatware on it but otherwise I am quite pleasantly surprised and happy as my primary reason for choosing to root the device was to enable hotspot. Does anybody suggest that I try to root this phone given that the hotspot is working.? Maybe this is a special version does not have the same locked boot loader as before? How should I proceed if I want to try?

Unlocked to accept another carrier Sim and unlocked bootloader are not the same thing. If it's AT&T, the bootloader is locked and you will most certainly brick your new phone if you try to root.

Thanks for the heads up.
I wonder why my tethering isn't blocked. It is working natively.

Unlocked firmware to Verizon S8

Has anyone tested yet the SM-G950U1 firmware from Updato.com in your Verizon S8 yet? prior to the S8 i had the 7 Edge with unlocked firmware and worked just fine, just wondering if this is official build on the net.

It is and it works. I'm using it now. Gear VR supposed to work also but I don't have one to say for sure.

Honestly I can't remember but I'm pretty sure it was either modified .12 or the unmodified version. I did update to the Canadian firmware first though because the U1 want available at the time.

I thought all the US variants of SM-G950U were bootloader-locked and hence we couldn't root. Are you guys saying that with this U1 firmware, it's unlocked and hence we can root? Link? I'm very skeptical this works.

Nobody said it was bootloader unlocked. It's carrier unlocked without any carrier bloat.

No, the firmware comes from the unlocked S8, which means is bloat free, has nothing to do with root.

I've had the U firmware for a couple of weeks and it works great. Just that there's no video calling. Haven't tried wifi calling yet. Those are two features I've barely used. Battery life is great. I think sprint forums are close to root so I might root after they get everything worked out.

Does Verizon's visual voice mail and HD Calling work?
Verion Video calling is no big deal for me, but I have used Wifi calling once or twice from a store that had no Verizon coverage, but had free wifi. I could live without it, but it would be a nice to have. Then again, no bloat, and some of the Samsung features like Cloud Backup would be cool.
Can this be flashed without tripping Knox/Safe flags? And/or is it easy to flash back to stock Verizon without tripping?

Yes, the HD calling works. Calls are extremely crisp. It's as if you were making a Messenger call over Wi-Fi. It's night and day.
I have the Verizon G950U variant and I'm looking for root, sadly this model doesn't have the "OEM Unlock" option under Developer Settings so I can't flash it without tripping Knox or my phone locking up.

Does anyone know if it's possible to use the Tracfone S8, and flash the Verizon S8 firmware to it? I followed steps from another site and it gave me a firmware with Cricket, Metro pcs, and T-Mobile bloat on it and it was most definitely not Verizon. Anyone have any ideas what might have went wrong? Downloaded Verizon firmware direct from SamMobile but that was what I got. Any ideas or help will be greatly appreciated, hope I'm putting this in the right place rather than start a new thread. Any help, tips, guides, download links, etc. will be greatly appreciated. Thanks guys!

I'm pretty sure that if you were to flash any rom or recovery other than the stock (and maybe even that, I'm not sure), it will trip Knox. Your phone might give you the whole "SEAndroid is not Enforcing" boot screen. This happened to me on my Galaxy Note 5, I even tried reflashing it's sitting in my drawer, lol.
I wouldn't take the risk unless you have been given a spare Galaxy S8 by Samsung to expirement with. It's a little too risky for me
I may be an idiot, but I do know that OEM unlocking isn't available in Dev options. I got my Galaxy S8 a few weeks ago and not quite ready to tamper with it.

I don't see any indication of HD calling anywhere, visual voice-mail is missing, but I use Google voice anyway.

People have been flashing all kinds of different carrier firmware as well as the unlocked firmware and nobody reported Knox bring tripped at all. Is fine to flash as much as you like.

Wasn't aware of that, I haven't seen anything on xda about it. Will other carrier's SIM cards still work on different roms?

You're kidding right? Those threads were one of the earliest ones posted since the phone was released. If you have an sim unlocked device, it'll work fine, its the same limitation as every other sim locked device. I converted my Vzw S8 to the US unlocked version since Vzw LTE phones come sim unlocked already. Using it on MintSim (Tmo) and it works perfectly fine. Have Wifi calling and VoLTE. If you have any other carrier phones, you'll need to have it sim unlocked to be able to use other providers even if you flash that carrier's rom.

Unlocked on AT&T

Ok so I have read some stuff that claims if I buy the unlocked Note 9 on best buy's website that my service with at&t will be inferior compared to a note I would have bought through their payment plan BS. Despite both having identical hardware and both being on the same service plan.
Is this true? Is there a easy way around it?
If not, what carriers do not do this?
Because for the past 2 years I have been using an unlocked axon 7, and lately I have noticed the service quality severely drop, and if this is the game AT&T wants to play then I will just move to another carrier and get a better promotion.

Going by the unlocked note 8 series on t mobile. I think most functionality works with their Network out of the box.
I'm currently using a unlocked N9 on Sprint, out of the box Rich communication text doesn't work nor does HD calling. Also the damn camera shutter sound cannot be muted lol.

I read something similar about using an unlocked version on on T-Mobile but I have had no issues so far. Some people were saying that the carrier versions will fully support all bands but the unlocked ones may not. If worst comes to worst you can just flash carrier firmware on your unlocked version and you'll be good to go.

It's not about the model, it's about the firmware. Regardless of reflashing or outright buying an unlocked firmware, the network detects this.
The result is loss of all network-propriety functions, including: WiFi calling, VoLTE, and other features.
If you don't care about them, power to ya.

Not sure about AT&T but on TMO, WIFI calling works on my Unlocked N9.
Carriers probably hate when you use unlocked phones because that's money lost for them. So they may make it seem like you're losing something.

TMo sends their HD voice protocol/implementation to Google so it's "baked" into the phone. ATT chooses to be private.

ATT sucks for unlocked devices.
not only do the mentioned services not work, the reception also sucks compared to att branded phones. i have multiple iphones and last gen galaxy phones such as the S8, they all perform very well compared to my unlocked note 9.
i think i'm going to return my note 9 to bestbuy and get it exchanged for ATT branded one.
i can then carrier unlock from att.
unless i switch to Tmobile, no more unlocked devices for me.
it's 2018 and i gotta dial my voicemail on my note 9, what a piece of crap

I haven't had that issue on AT&T out west . HD calling and stuff doesn't work, but download speed is just the same as it was a carrier branded phone.
Also why not flash the AT&T firmware, instead of returning the phone?

Keep in mind that if you DO buy the unlocked version, you can flash AT&T's firmware on there for the full experience. You just won't have to deal with AT&T's incompetant SIM Unlock team if you ever leave (or sell it).

i've been trying to flash ATT firmware with this:
https://forum.xda-developers.com/galaxy-note-9/how-to/stock-official-attodinn960usqu1arg9-t3828691
no luck, seems the file is corrupt.
i know i can download official ATT stock firmware from sammobile.com.
but here;s the question:
every single usa version of the phone has the bootloader locked and safestrap does not work in oreo 8.1 as far as i'm concerned.
how do i flash this into my note9?

No flashing isn't hard. I have not done it for a while. Just make sure to read a few threads on it. Make sure you're using the latest method as some details can change and of course RTFM more than once and all the details. And if you're uncertain don't be a guinea pig and wait until some veterans verify the process. Soft bricking is possible and unbricking can be impossible for the technologically inclined. I forgot what phone, I think it was actually Galaxy Tab S2 I thought I hard bricked. Took me a couple days to get it back to functioning. There are many stories this some worse than mine.

Thanks, will check into it. Still on the fence with getting unlocked ATT phone. Someone in another forum said he has bought two unlocked Samsung's for ATT and both had issues staying on LTE. But he hadn't flashed ATT firmware .. He was in low signal area so don't know if he was just unlucky or what...

I also have a US unlocked n9, which i got directly from Samsung.
Here, there's a guide in
https://www.sammobile.com/firmwares/SM-N960U1/ATT/download/N960U1UEU1ARH2/231817/
You can either download the firmware from the link above, or from Venom's ATT thread. Either way, if you want the latest , just flash either, then trigger OTA. That's what I did. Now I'm on latest official ATT fw in my US unlocked n9.
And no, you don't need an unlocked bootloader for this. Will NOT trip know since these are OFFICIAL firmwares.

Wifi calling with an unbranded Note 8

I bought an unbranded Note 8 directly from Samsung. I find that this version does not have native Wifi calling. I am aware of some services that provide free Wifi calls as long as both are using the same service (Skype, whatsapp, and so on). My current provider is AT&T, FWIW.
Has anyone found any app or workaround that provides me with Wifi calling? Is there any way to get this for general phone work?

You will need to flash the ATT firmware with ODIN. Just be aware that it will also add ATT bloatware apps.

If you're on ATT, you'll need to use ODIN to flash the carrier firmware. This will bring back WiFi calling and VoLTE. But it will also bring with it all the carrier bloatware apps.

He just said he has the N950U1 which is the Snapdragon model, so detanator doesn't apply here.
