Wanted to start a thread to discuss any success or stories about using your XZ1 on T-Mobile USA with VoLTE or WiFi calling? Anyone got a chance to buy the phone and try it out on T-Mobile USA? lets keep the chatter to minimum of facts and real feedback of users experience and not (it should work, or in theory it should work, or even Sony said it will work). I am looking for real user experiences on their personal phones running VoLTE on T-Mobile USA.
[Sony Xperia XZ1  Questions & Answers] spielnicht:
I read on the Verge that only the Compact would come compatible with T-Mobile's VoLTE and Wifi Calling. I don't know why that is nor how it makes any sense (considering they're pretty identical). I can confirm at least that neither VoLTE nor Wifi Calling works on AT&T...not that I ever expected it to be otherwise.

XZ1 Dual is already available to buy at Amazon and it looks like few people already jumped ship according to

https://www.reddit.com/r/SonyXperia/comments/70ac8s/international_xperia_xz1s_have_hit_amazon/

I have asked if anyone can provide status update with tmobile volte once they receive it.
[Sony Xperia XZ1  Questions & Answers] hnt20:
so far, no confirmation from any real user experience that XZ1 actually works with T-Mobile USA VoLTE. I have reviewed the reddit discussion, again, no confirmation there as well.
[Sony Xperia XZ1  Questions & Answers] VeixES:
Have not seen "Customized US" region firmware appear for XZ1 Dual (G8342) in https://xpericheck.com/ so i am a bit skeptic about what version is sold on amazon.

Customized US firmware is needed for sure for VoLTE/VoWIFI to work without root.
[Sony Xperia XZ1  Questions & Answers] GuestK00307:
Can a different region firmware flashed without root?

Can the dual sim variant 8342 be flashed with a single sim 8341 firmware? Of course 2nd sim capability will be lost.
[Sony Xperia XZ1  Questions & Answers] hnt20:
can we please keep this thread to talk about users experience with XZ1 on T-Mobile rather than loading builds.
[Sony Xperia XZ1  Questions & Answers] RockStar2005:
I just spoke to T-Mobile's Tech Dept and they really have no clue if it's VoLTE-certified or not. Since the majority of online publications say it isn't and only the XZ1 Compact is, I'm going to assume it's not. Guess I'm sticking with my HTC 10 a little longer then! lol
[Sony Xperia XZ1  Questions & Answers] hnt20:
Agree, seems Sony did it again by limiting their unlocked phones to work only on handful of networks.
[Sony Xperia XZ1  Questions & Answers] RockStar2005:
Yeah. They're slowly getting back on track again, considering that XZ1 has excellent battery life (82 endurance hours on GSM Arena, "Excellent" rating on Phone Arena), HDR screen, improved audio from what I'm understanding (though I'm still THOROUGHLY researching that lol), metal unibody is awesome (enough with glass backs! lol), and at least certifying VoLTE for the unlocked XZ1 Compact (it's a start, I guess lol)...........it seems they are getting their sh*t together. So hopefully in 2018 we'll see them quit playin' around like dummies and do EVERYTHING right, not just a few things.
[Sony Xperia XZ1  Questions & Answers] 1230m:
Aww, man! You sure? You don't want the iPhone X? Haha, I think it's funny apple is switching back after the monster failure of the 4s's glass back.

This is very much up for debate, as you said your representative wasn't sure, but said maybe the Compact only? I am talking to a rep now (have been for near a half hour or longer), the initial person didn't know (they kept saying "the SIM card will work in an unlocked Sony phone", which is not the full answer to my/our question here). After much discussion, the initial rep basically said they don't know, but in theory (I know we don't want theories here, so this isn't too helpful, but my experience...) it should work, although, it hadn't been tested by t-mobile themselves or something, so they couldn't guarantee it. I found this site "spectrumgateway" ( then navigate to the "Devices compatible with Extended Range LTE") [sorry, I can't post actual links yet]. This webpage lists the XZ1 and XZ1 Compact under the "may work" category. If you notice, the page also says to try to contact t-mobile/the t-mobile community if you happen to test one of the "maybe" phones, as they're "maybe" because t-mobile doesn't know and hasn't tried (but in theory should be compatible). So, I really think those third party articles have no idea what they're talking about and t-mobile seems to have no idea if the new sony phones will actually work, in reality.

After more talking to the initial rep, he goes and grabs someone else (I don't know who? maybe a supervisor?). This person does not seem to know either. They've both claimed wifi calling should work fine on the unlocked/VZW iphone 5s i currently have, which is completely not the case. So, who knows?

I think I thought that to myself 6 months ago with the XZs came out, then a year ago when the XZ came out, and even a year before that too. Not sure I am going to hold my breath anymore.

Edit 1: Okay, after rounding out my conversation with the supervisor... they basically determined that they cannot guarantee the XZ1/XZ1 Compact will even work (although, per the third parties info/specs (Sony), it *should*) and no one has tested it for sure (and it doesn't sound like they plan on it, themselves, so it's up to consumers, I guess). That all said, I still wouldn't be surprised if wifi calling, hd voice, volte, etc. didn't work. The supervisor directed me to t-mobile's support page, where I searched an article called "Wi-Fi Calling" from t-mobile (it was the third result for me, dunno for others) [again, sorry, I can't link]. It's more or less a page on their wi-fi calling policies and how to use it and such, but may be useful.
[Sony Xperia XZ1  Questions & Answers] RockStar2005:
I respect Apple iPhones, but I prefer the freedom of Android. lol

No it's NOT a maybe for the XZ1 Compact being T-Mobile VoLTE-certified. ALL online publications indicate the XZ1 Compact will have it. Only like ONE (Android Headlines) said it was both, but I think they jumped the gun by assuming something that should've been the case anyway but wasn't. A rep with who, Sony? Or T-Mobile? Cuz if it's T-Mo I already went that route with both customer service and their tech dept.

Yeah Spectrum Gateway wasn't sure and it turns out it's only the XZ1 Compact. I wanted to contact them but they didn't put a "Contact Us" page on their site. Dumb. lol I have their page bookmarked, so actually 2 sites say both have it, but if you click on their "source link" for that info, it takes you to...........Android Headlines. lol

At this point I believe the XZ1 Compact got certified, and the XZ1 didn't. Until someone can prove that wrong, I'm not going to dispute it. So that's that.

Sony has made like its best phone yet in the XZ1 IMO, but this is unacceptable. I have faith though that they will come around with their head FULLY out of their a$$ by 2018 though. The XZ1 Compact is a great buy though. If it only had a bigger screen, then it would basically BE the XZ1 since they both have the 835. Not sure on body of XZ1 Compact though, but it p's me off b/c I've been waiting for an all metal-unibody Xperia phone. And now we got one, but it turns out to be a dud in one major way (no VoLTE). I get Band 12 in my area now, so VoLTE is a MUST for me. When I didn't have it before I didn't care, but it just got put up and activated in my area (Chicago) about 2-3 months ago. And you need VoLTE to use it on T-Mo's network since they require certification, so yeah. It's a pass for me, unfortunately. And unfortunately for Sony too.
[Sony Xperia XZ1  Questions & Answers] 1230m:
I feel ya, apple iphones are generally fairly quality. Sorry, I shouldn't have ragged on them. I have just had mine for a while and am ready to switch (back -- its been *years*, so not sure you could even say 'back' anymore lol) to android.

I know, but these are all third party articles. I presented many to both the t-mobile rep and the t-mobile rep's supervisor, to which they both said those articles could be wrong and t-mobile isn't endorsing any of them or anything. That's why I said it should work (but I think people want real tests here?), but t-mobile said they would not guarantee either phone working despite all the articles (to which I said, they needa get out a statement then or something to correct any misinformation before tmo ends up with a lotta upset sony users on their hands, but thats another topic).

T-mobile. They told me the opposite of what you got told, by the end, at least (before the end of our conversation they had opinions and "answers" all over the board, many of which I think were misleading/incorrect, so maybe what they told me about the XZ1/XZ1 compact was incorrect too). I'm not trying to argue or anything, just reporting my experience.

I think it says just post on r/android? Lol

Yeah, I had come across the spectrum page before, but somehow missed the XZ1 stuff (and links) further down, so I was like "OH!? Did it get it added? ...Oh? It's a "maybe"? Well, let's click this link.... Aww! man! full circle!" -- Lol, maybe, it's like a information source loop? The entire internet thinks Sony phones work on tmobile usa because two websites basically quoted each other? xD Just kidding.

Yeah, I think I am siding with you at this point. T-Mobile wouldn't confirm either for me, but I think you're coming to the right conclusion based on what I've seen (if I had to guess).

Maybe. Although, each year, my theory that they consider the U.S. an "already lost to competitors" cell-phone market and just don't care creeps more and more into my mind.

I like "smaller" phones, so I was kind of actually eyeing the compact. Although, I do agree, a metal body would be cool (but, I don't think the compact is as "plasticy" this time around? Idk, Sony says the material is some material hybrid or something (as many manufactures say. I think a lotta times they just make up cool sounding names for their epoxy recipes, lol, maybe next time... = "Mithril! Unibody"! "OOOOhhhh!!!! Ahhhh!!!!!" ? I also like that, despite the XZ1 being larger overall, it is thinner, making it easier and more comfortable to slip into a pant pocket or whatever.
[Sony Xperia XZ1  Questions & Answers] Heinous:
Yes, please.
[Sony Xperia XZ1  Questions & Answers] tlxxxsracer:
I ordered my XZ1 G8342 on ebay. Should be here Monday at latest or saturday (crossing fingers). I'll be sure to upload some videos and keep everyone posted. I had the x compact and experience using flashtool as well.

Tmobile told me that if the phone doesnt have VoLTE, you may not be able to use LTE while on a call and may take a minute to get LTE active after a call.

We shall see
[Sony Xperia XZ1  Questions & Answers] RockStar2005:
The big issue with not having VoLTE on T-Mo (who I also have) is that you can't use Band 12 (aka 700 MHz), which is becoming more and more prominent. It reaches out much farther than their other bands (2 & 4), and is 4 times better at penetrating buildings as well.

Yeah keep us posted man! With pics too. Thanks.
[Sony Xperia XZ1  Questions & Answers] tlxxxsracer:
Trust me, I sure will. Will see if band 12 is being used.

Ordered the blue :good: $609 shipped
[Sony Xperia XZ1  Questions & Answers] ms2398:
Yes, that is the tool. It gets installed onto your PC. The curate firmware files are downloaded directly from Sony using the tool called Xperifirm.
[Sony Xperia XZ1  Questions & Answers] pbarrette:
See the XZP thread starting here.

Note that user [MENTION=3555225]pikeylfc[/MENTION] has his bootloader unlocked. So he copied the files from my post to his OEM partition.

If your bootloader isn't unlocked, and you are using the XZ1 instead of the XZP, you may be able to flash the XZ1c's Customized US OEM sin file directly. Doing that doesn't work for the XZP because the firmware is signed with a different certificate, so the bootloader on the XZP prevents flashing it. The XZ1 and XZ1c may share the same certificate, so you may be able to cross-flash the XZ1c's OEM sin file directly.

If your bootloader is unlocked, and you followed the thread listed above, I put together a TWRP flashable zip file for the XZP, but it should also work for the XZ1.

If you're wondering how it all works, I've got an XZ1c post here, and here that describe what's going on.
[Sony Xperia XZ1  Questions & Answers] ms2398:
Correct, because you essentially use a non US rom (which has fingerprint enabled) and replace 1 file in the foreign rom with a file from the US rom.
[Sony Xperia XZ1  Questions & Answers] RockStar2005:
Ok so there's 2 tools that you have to download to PC then?
[Sony Xperia XZ1  Questions & Answers] ms2398:
Yes. If you saw pbarrette's post above, he has a great write up on this stuff. Major props to his research and contributions. Are you intending to try this on the XZ1?
[Sony Xperia XZ1  Questions & Answers] RockStar2005:
Ok cool.

No, but I know at least one person who may wanna get the XZP or XZ1 now that this has been confirmed. lol

Thanks again ms!!!
[Sony Xperia XZ1  Questions & Answers] pbarrette:
Well.. It's confirmed on the XZP with an unlocked bootloader only and wholly unconfirmed with the XZ1.

The XZ1 should work with an unlocked bootloader and MAY work with a locked one, but both are unconfirmed at the moment.
[Sony Xperia XZ1  Questions & Answers] ms2398:
Right, no one has been brave enough to test the locked bootloader method with the XZ1 Compact US oem file yet.
[Sony Xperia XZ1  Questions & Answers] RockStar2005:
Ok wait, so you DO have unlock the bootloader on the XZP to make all that work? lol Or no?
[Sony Xperia XZ1  Questions & Answers] pbarrette:
Yes.

On the XZP, you have to unlock the bootloader in order to write to the OEM partition.

The XZP firmware is signed with a different key than the XZ1c, so attempting to flash the XZ1c's OEM sin file fails with a signature check error.
[Sony Xperia XZ1  Questions & Answers] RockStar2005:
Ok. Well thanks to you both for kindly sharing all this great info!
[Sony Xperia XZ1  Questions & Answers] RockStar2005:
Hey pbarrette,

Does it make any difference if a person wanting to do all this buys the U.S. version of the XZ Premium vs. the int'l version? I'm thinking no, but just wondering.
[Sony Xperia XZ1  Questions & Answers] pbarrette:
If you're planning to immediately unlock the bootloader, then buy whatever is cheaper.

The difference between the Int'l versions and the US version is:

1] Which firmware the phone ships with, and

2] Where the warranty is valid.

Since unlocking the bootloader immediately voids the warranty, point #2 doesn't matter.
[Sony Xperia XZ1  Questions & Answers] RockStar2005:
Ok thanks!

One thing I just remembered though................all this is great, but with regards to the ability to enable VoLTE, for T-Mobile users like myself and others, it's not gonna be worth doing all this (except for getting the FS back, which still arguably makes all this worth it) because Sony DID NOT certify the XZP with T-Mobile for VoLTE. And since they did not, I don't believe you'd be able to actually USE VoLTE while on T-Mobile even if you do all this. The XZ1..........maybe. Some reports did say both the XZ1 Compact and XZ1 were VoLTE-certified with T-Mobile, but I'm just not sure anymore on the XZ1. It's honestly exhausting following up on all this. I REALLY hope Sony Mobile gets its head out of its A$$ in 2018 and cuts all this no FS and VoLTE crap once and for all. But if you have AT&T or any other GSM-based carrier, then I'm almost certain VoLTE will work based on past experience.

Either way, all this info is MUCH appreciated pbarrette!!
[Sony Xperia XZ1  Questions & Answers] pbarrette:
No. You're wrong.

At this point we have a confirmed XZP user (pikeylfc) who is able to use T-Mobile VoLTE and VoWiFi and 1 XZP user who is having trouble getting it working. (I think the difference at this point is that the working phone is the Dual-SIM G8142 and the non-working one is Single-SIM G8141, but don't have any feedback on that yet.)

We have zero XZ1 users with working T-Mobile VoLTE.

We have zero users with working AT&T (or any other US, non T-Mobile carrier) VoLTE on the XZP, XZ1 or XZ1c.

If you buy any of these phones with the expectation that VoLTE will work on any carrier other than T-Mobile, you will be disappointed.
[Sony Xperia XZ1  Questions & Answers] RockStar2005:
Ok. I guess the rules have changed since last year. I and someone on here bought the Xperia X Performance (both were the int'l models and both were dual-SIM models). I had T-Mobile, he had AT&T. I did not have VoLTE, but he did. Not sure what changed since last year, but apparently something has.

Well that's great news then I guess for T-Mobile people. I've never been happier to be wrong about something! lol :D

So ok, either U.S. or int'l XZP and preferably the dual-SIM version for better results. Got it!

It's so krazy to me that NO XZ1 people can get VoLTE on T-Mobile but the XZP with this special mod flashed on it DOES get it. Krazy with a K!

Well to me it doesn't matter although I do know one person with AT&T that I was telling should consider the XZP b/c I thought he'd have VoLTE for sure. I guess I'm happy he went with the Note 8 instead. lol

Thanks so much once again pbarrette!!!!!!
[Sony Xperia XZ1  Questions & Answers] RockStar2005:
I was looking at some of the user comments for the Int'l Dual-SIM XZP on Amazon, and someone mentioned this in response to a person saying they couldn't get LTE on AT&T:

Gclancer1 month ago (Edited)Report abuse

The problem is with AT&T, not the phone. AT&T requires you to register your new phone's IMEI# to enable LTE or you will never get LTE with AT&T (Especially with unlocked phones). Unlike T-mobile, i can just pop in the sim to get LTE+

I wonder if the reason people aren't getting VoLTE (as well as LTE) on AT&T with the XZP is because they aren't doing this? What do you guys think?? I wonder if someone got the XZP and called AT&T and registered their IMEI# if it would also unlock VoLTE in addition to LTE.
[Sony Xperia XZ1  Questions & Answers] pbarrette:
I think that you haven't actually read the many, many posts which explain what is required for VoLTE to work.
[Sony Xperia XZ1  Questions & Answers] RockStar2005:
If they were in this thread and recent I probably did. I'm saying this would be IN ADDITION to what those posts have to say. Maybe I should've clarified that.
[Sony Xperia XZ1  Questions & Answers] Sliftw:
Just wondering if using the files from the US XZ1C would work to give VoLTE and WiFi calling with T-Mobile on the XZ1 dual SIM like it does with the XZP?
[Sony Xperia XZ1  Questions & Answers] vapors2k:
Sorry to bring up an old thread but I'm in dire need of a new phone, screen cracked on my Z5 rendering it useless. I don't think I can wait for the XZ2 and there's word on whether that will work with T-mobile USA VoLTE and VoWIFI.

So...from reading 20 pages the XZ1c comes out of the box compatible to work with T-mobile USA VoLTE and VoWIFI but the XZ1 needs to be modified? And there's preference on which model to get since both the international and US version can be modified?
[Sony Xperia XZ1  Questions & Answers] krchi:
I would be willing to flash the XZ1C oem.sin file on my G8341, but I am wondering lets say that the flash doesnt work successfully. For those who know or have experience, what happens when you flash another Xperia device's file into anothers? Bootloop? hardbrick?

EDIT: I have the international version of the XZ1 G8341 but I am in the US, using Mint (MVNO of Tmobile) I just flashed the oem_X-FLASH-ALL-C93B.sin from the XZ1c Customized US and I got the VoLTE setting to show up but I have not got it work in actual calls yet. Also I notice that now instead of dropping to 3G/H+ in phone calls my phone just disconnects from data when in phone calls (a factory reset fixed this but volte still did not work) but yea, the file is safe to flash on the international xz1 atleast. My model number also remained as the XZ1 model number.

EDIT 2: Also tried CE1 firmware and it did not work, this is as far as I can experiment without rooting/unlocking bootloader which I do not want to do to my device yet.

TL;DR: flashed oem.sin from xz1c and volte doesn't work.

EDIT 3: I have since got this to work, refer to post 213.
[Sony Xperia XZ1  Questions & Answers] krchi:
If a US xz1 user (G8342) could test it out and see if it's working for them or not that would be great.
[Sony Xperia XZ1  Questions & Answers] Sliftw:
I have a XZ1 G8342 on the way and will test it with USA T-Mobile. Since someone got VoLTE working on an XZP i dont see why it would be impossible to do with the XZ1.
[Sony Xperia XZ1  Questions & Answers] RockStar2005:
Yeah if you apply the XZ1 Compact mod to the XZ1, I think it will work too.
[Sony Xperia XZ1  Questions & Answers] krchi:
Which is why I tried it on my G8341 model and it did not work.. However as far as I am aware there shouldn't be any hardware differences between the 2 other than dual sim.
[Sony Xperia XZ1  Questions & Answers] pbarrette:
I haven't looked at the G8341 firmware, but my guess is that it lacks the modem file for T-Mobile VoLTE.

See the thread here where I mention the

amss_fsg_poplar_dsds_tmobile_us_ims_tar.mbn

file. I was specifically referring to the file on the G8342, which is why you see the "dsds" bit (dual SIM).

The key bit is that the XZ1c's US OEM bits turn on the options, but also use a reference to "tmobile_us_ims" to load the right modem file from the system partition. If you don't have a modem file with "tmobile_us_ims" in the name, you won't get the T-Mobile VoLTE modem firmware loaded.

So you may be able to flash an entire G8342 firmware, then flash the US XZ1c's OEM SIN file and have it work.
[Sony Xperia XZ1  Questions & Answers] krchi:
Any idea what would happen if I flashed a dual sim firmware into my single sim device?
[Sony Xperia XZ1  Questions & Answers] pbarrette:
I haven't got the foggiest clue.

I do know that the bootloader handles fastboot. So if you don't flash it, you should still be able to get into fastboot mode, which means that it is unlikely (but still possible) that you would hard-brick the phone.

So it may work just fine, or may not work at all.

I seem to recall another thread where someone cross-flashed a dual-sim to a single-sim, but I don't recall if that was a XZ1, XZ1c or XZP, and I don't recall which direction the flash/hardware combination was.
[Sony Xperia XZ1  Questions & Answers] krchi:
Any idea which file in the firmware contains the amss_fsg_poplar_dsds_tmobile_us_ims_tar.mbn file so I could flash that instead of the whole?
[Sony Xperia XZ1  Questions & Answers] pbarrette:
It's in the system SIN image. Which means you'd have to flash everything except partition and boot because otherwise the other firmware files will expect the single-sim variants of the system partition, but you'd have the dual-sim variant installed instead.

The partition and bootloaders are, so far as I can tell, all the same.

Specifically, all the modem files are found at

/system/etc/customization/modem/

.
