Anyone using a SM-G930F on T-Mobile US?

I contacted T-MO support and they say the SM-G930F is 100% compatible, but not sure I trust them. Are there any issues with HSPA support or has the network re-work been completed?
Thanks.

No wifi calling no volte other than that it should work fine

the biggest thing to think about is that the g930f and g935f are suppose to be region locked. Meaning you have to make a 5 minute call using a european sim before the phone will sim unlock to allow the use of a US sim. Im waiting for someone who has purchased a g930f or g935f to verify this

I have read that as well. I'm asking because there's a sale on eBay, and they're shipping from the US. Haven't contacted the seller re: the region lock, but it would be very odd if they're selling unlocked phones in the US that can't be used. Certainly something to clarify. Without full T-MO support I'm not a buyer anyway, so that was my first concern.

yep, i just bought the g935f, on ebay as well...i did send a message to the seller asking to clarify if these phones will work in the US due to the supposed region lock.
I agree, it wouldnt make any sense for them to be selling these phones in the US, if they cant be used due to the region lock, everyone would be returning them.
Either way we will know for certain next week, as i think a bunch of us have jumped on the crazy deals, ie G930 for 599, g935f for 699 (no tax)

Hes talking about bringing an international device (g930f) to tmobile (hence the tiltle), in which case a person with a g930f (like in the title ) got wifi calling working...what are you talking about???
As far as region lock is concerned, i would assume like you that it will come region locked...but if youve been keeping up with some of the threads here, im sure your aware of all the assumptions regarding bootloaders...id prefer to have someone in the US actually confirm the region lock on the g930/5.

Every unlocked device I have used on tmobile doesn't have wifi calling or volte even if the phone is capable Google byod tmobile and wifi calling and show me someone with it working and if u purchase from amazon and the phone is locked just send it back

I'd much rather find out if the G930F will work before ordering it than go through the hassle of sending it back. Just doesn't make sense that a company would sell phones that don't work, but stranger things have happened. Thus my original post. I have no interest in rooting or alternate ROMs. Right now seems like I need to wait for the TMO version.

With the 930T you will get T-Mobile VoLTE, WiFi calling, and Band 4 3G in areas that have not been refarmed (is there still any left?), and T-Mobile support (and update, if they ever come out, LOL). I included support in one the pluses despite not ever relying on the provider for device support as I always root and custom ROM all phones.
If you don't care for any of the above, then the 930F would work and you could get it cheaper (even more so if you happen to have eBay Bucks), though if you factor the promotional offers, the 930T may end up cheaper.

I have ordered the G930F from eBay as well and that seller has sold a ton of them. I can't imagine that he wouldn't know about the region lock thing. Otherwise that would be so many returns lol

Just 930T cannot be rooted due to the locked bootloader... In this aspect 930F should be better. If it works with TMO.

Has anyone gotten one of these yet and can comment on VoLTE? I'm more concerned with that than Wi-Fi calling.

Only phones that have VoLTE are tmobile branded phones

I'm extremely interested in this possibility. Not keen on losing VoLTE & especially WiFi Calling, but if that's what it takes to get a rooted S7, I would happily settle for this.

Hi! I got my Samsung Galaxy s7 930f today, so I was testing. Everything working fine, hsdpa, lte, I do not use VoLTE or Wifi calling, so I can't tell anything about it.
The price was $599 on the ebay. I use it in Clearwater, Fl, so looks like here the hsdpa working 1900mhz not 1700.
I have only one problem, the signal is little bit weaker than my another phone " Sony Xperia Z3 Compact ".

I started looking into the framework for the G935F and G935T and from what I see, there are a lot of changes that Samsung made to get VoLTE to work with T-Mobile's servers. They did not go with the AOSP implementations of VoLTE and Wifi Calling that Google introduced in Marshmallow. They're still using the same custom implementation that they used on the Note 4. It's not easy, but I think it's possible to make VoLTE work with a custom ROM. If T-Mobile/Samsung won't unlock the bootloader of the G935T by the end of my return period, I'll probably buy the G935F and take a stab at making VoLTE work.
@Python_69: Was your device SIM and region unlocked when you got it? Did it work with a T-Mobile SIM right out of the box? Also, if you wouldn't mind, could you test if your phone can receive a band 12 LTE signal (for data only of course, since we don't have VoLTE yet)? Thanks!

If it becomes possible to run a rooted Exynos S7 on Tmobile & enact wifi calling & volte, it could basically become a work around for the locked bootloader of the 820 for those looking for TW based ROMs. I'm one, & from what I've read, the exynos sounds better for my needs anyway.

AT&T or T-Mobile for unlocked S8+ ?

The backstory.... Preordered an ATT Note 7 and had many headaches with delivery / billing. I am now living with my old Note3 using Goggle Voice/Hangouts because of my weak signal (all carriers) at home. I'm using a pre-paid Straight Talk plan when away from home.
I've been waiting patiently for the S8+ and now need to decide between AT&T and T-Mobile for a GSM phone. I plan on paying full cash price and having it unlocked to use a 3rd part prepaid plan (Straight Talk or ?).
I considered a factory unlocked phone (Best Buy, May 9th??) but I am told that those will also have a locked bootloader. Up until the Note 7 I always ran rooted with custom ROMS. I became a big fan of Samsung Pay which I think also means a locked bootloader with no root is needed. Of coarse, bloatware sucks. I had good luck with Package Disabler Pro on my Note 7. I will be using my Google number, if only for forwarding to another number. WiFi calling is a must one way or another.
My Note 7 from ATT let me run Mobile Hotspot at the same time WiFi was enabled. This made it easy for giving my Android head unit in my car Internet access. The T-mobile version at the time needed to be turned on and off.
I'm leaning toward T-mobile only because of my bad blood with ATT. ATT coverage is marginally better in my area.

Either and flash the OS on it with ODIN. It is the same hardware so it doesnt matter.

Yes and also if the T-Mobile version is going to have an unlocked bootloader, flashing T-Mobile firmware should allow you to unlock it through the OS.
But it's highly unlikely it will have an unlocked bootloader, although T-Mobile have supported it, I don't think it's happening.

I get that if you buy a carrier phone and then unlock it. But what about the factory unlocked phones sold in the US?
I've heard that the bootloader on those phones is also locked, but not from a real good source of info. I've also heard international versions do not have a locked bootloader and do not support Samsung Pay. They also do not support CDMA (which doesn't bother me at all).

If I flash via ODIN does that kill Samsung Pay? What about Knox?

I'm in a similar situation and my first concern is what bands both phones support. Online it seems AT&T covers both GSM providers perfectly. The info on T-Mobile and its bands is extremely lacking. My second concern is the process of unlocking either fully paid off phone for use on the other. I think I can have TMobile unlock it for me but I'm not sure how it works with AT&T. The easiest solution is the unlocked version but thats not even got a release date set in writing anywhere.

As long you are flashing official firmware from Samsung nothing will break. Knox will not be tripped and Samsung Pay will work.

It is my understanding that all US (Snapdragon) phones cover all bands, including CDMA. That means you could even take an unlocked AT&T phone to Verizon. I'm not used to that! It even has LTE-U which TMo is supposed to be soon supporting.
I am an ex AT&T customer. They unlocked my Note 7, and again with the replacement, without issue. I seem to remember there was a wait period at first. 7 or 14 days?
The thing I'm considering is also the VR incentives for pre-ordering. I can tell you AT&T messed up my Note 7 pre-order. They shipped it on the release day by a slow method. I ended up going to a store and buying one outright and returning the unopened one once it arrived. That caused a billing nightmare that I had to call them every months until I finally turned it in and closed my account.

Can you recall where you read the carrier versions support all the bands just like the unlocked versions? All the info I found from the carriers shows different bands on each model.

You're missing what I'm saying... There will be no unlocked bootloaders on any Samsung S8 phones for the USA. You cannot get one from carrier or factory.
I think you may be mixing up Bootloader unlock and Sim unlock....

I do remember that it was a story about FCC approval of the factory unlocked (SIM) phone. Keep that in mind that it may be the unbranded, factory unlocked phone only, but the article did say they were all the same. The locked carrier phones may not be so flexible.
Other things I've found.. Best Buy SIM unlocked does not get the incentives. Best Buy, and their cheaper price, does not seem to offer a T-Mo phone.
The VR incentive is attractive to me, but is not a must have. At this moment, until I can find out for sure if Samsung Pay will work on an international version, I am leaning towards a T-Mo pre-order. But that is me and my preferences YMMV. I have a major dislike for AT&T.
Looking for where I read it. In the mean time this may be interesting to you.

It appears that going by this information the factory unlocked and the AT&T are NOT the same https://www.frequencycheck.com/compare-devices/6MQWs05y/samsung-sm-g950a-galaxy-s8-td-lte-samsung-dream/samsung-sm-g950f-galaxy-s8-td-lte-samsung-dream
You're correct that it seems T-mo info is evasive.

Hello,
I would like to know, if it posible to buy the Galaxy S8 from the samsung web page (att version), then unlock it and after that flash the unlocked rom flashing it with odin.
Can someone help me?
thanks.

Just ordered the 955F from Clove...
I'm hoping that missing bands won't hurt my AT&T usage much. Or any prepaid sims I may throw in there.
Will see if the 955U info comes out before my phone, and will decide if I want to cancel.

Unlocked S8+ on AT&T?

Hello all,
A friend of mine is on AT&T and thinking of getting an US unlocked S8+ to use. He asked me what he might miss out on by not getting the AT&T version. I'm thinking VOLTE, maybe wifi calling. Idk. Can anyone enlighten us?
Thanks.
-evilhunter101
P.S. I swear this is really for a friend, I'm using a Verizon S8+ on Verizon :good:

I had bought an AT&T version of the S8 plus and unlocked it, then i switched the fw to the unlocked version and now i am able to use it on any carrier i want. The only problem is that i have to activate my service on one of my older phone that used the carrier i wanted.
Honestly, won't be missing out on much

So basically nothing missing. That's good to hear. He's already on AT&T but I don't know the sim card size of his current phone. We'll deal with that when we get there.
Thanks, appreciate the information.

I think you're right about WiFi calling unless there is some other way to add it. I'm looking for a solution for that. I just switched my AT&T S8+ to an unlocked ROM and that is the thing I miss the most. Not sure about volte.

Unlocked Note 10 + - Unable to flash T-Mobile Firmware

I wish I would have known that WiFi calling wasn't supported on unlocked Note 10 + before purchase. I need WiFi calling and so I am trying to flash the T-Mobile firmware onto my Unlocked Note 10 +. The problem is that I am not getting any of the T-Mobile branding or features after flashing. I think this is because it doesn't recognize my SIM as being a T-Mobile SIM. I use Mint Mobile which is a MVNO running off the T-Mobile network. If I would have just kept my Google Pixel I would have all the features that I need that T-Mobile offers such as the WiFi calling and HD voice.
Is there any way for force the device to enable the T-Mobile specific features available in the firmware? I am thinking about going and pickup a prepaid T-Mobile SIM to see if it will activate the features with that. I am beyond frustrated at this point as I have an expensive phone that I can't get any of the features on that I had on my Pixel 2 XL.
Any help is greatly appreciated.

I have an unlocked Note10+ (N975U1) with T-Mobile (standard unlimited-everything plan), and WiFi calling works fine for me with the default unlocked firmware.
You may be right about the sim card. If T-Mobile is your carrier, can you get a regular sim card from them?

I don't know the answer to your question, but can tell you of a similar experience I had buying an unlocked Note 8 from Samsung and trying to use it on Verizon network. No WiFi calling, visual voicemail and other notification features, in spite of hours spent on phone with Samsung and Verizon. I ended up returning it and buying the Verizon branded one. Lesson learned! There are cons as well as pros with unlocked phones.

It depends on the carrier. T-Mobile is good about supporting its features on unlocked Notes, definitely including WiFi calling. Verizon is not.

Need to switch stock AT&T f/w over to T-Mobile

I was part of my sisters AT&T family plan and I had recently traded my S8+ in for the AT&T version of the Galaxy Note 20 Ultra SM-N986U. Well sis got fed up with AT&T pricing and wanted to switch. So I was forced into paying off my phone & the 4 of us switched to T-Mobile . Me & my wife have our own plan and no longer part of my sisters. So after unlocking the phone the port went fine but I want to switch my f/w to T-mobiles. Will there be any problem in doing so?

If the phone is unlocked, you should be fine. Both use the same base firmware.
You may or may not get all the T-Mobile features. There is a fix for that if you don't get all the T-Mobile features, but it typically involves wiping/resetting your phone.

Did you have the T-Mobile SIM card in it?
If not, it will revert to it's initial build CSC. AT&T in this case.
The other option is to manually change your CSC from ATT to TMB. There are threads here on how to do it.

I guess since its a USA based Snapdragon I cant even root it. Yes I did have the T-Mobile SIM card in it. I have tried 2x with stock T-Mobile fw & it still thinks its AT&T. The working network does show T-Mobile, but I would like to get the AT&T f/w off of it. So I will research how to manually change your CSC.
