[Sony Xperia X Performance Questions & Answers] RockStar2005:
Ok guys....... this time I called T-Mobile's Tech Support Team........ and got to the bottom of this, in 2 parts:

I explained the situation to the tech support rep I spoke with. I told her that I wanted to get the XP, and that the phone did not have VoLTE and I wanted to confirm whether or not I could make or take a call while in an area that was 4G LTE-only. She made the call on her phone with VoLTE off (her work area was 4G LTE-only, which she confirmed herself on their system), and it worked just fine. So I don't know what that article was talking about, but apparently the issue has been fixed.

But then there's the lesser but still important issue regarding making a call with the XP with no VoLTE in an area with Band 12, and would you be able to use it. The answer given here by the tech support expert was that the phone would be able to use 4G LTE for data during a call, but WOULD NOT be able to use Band 12 for the voice part, which means that if I'm indoors I would NOT be able to take advantage of the Band 12 spectrum, which as we all know is much better at penetrating through buildings than the higher bandwidth spectrums are. Right now this doesn't matter as my area (Chicago) does not have Band 12, but again a deal was just finalized where T-Mobile bought a bunch of Band 12 spectrum and within about 6-8 mos, it will be activated for customers to use. But with the XP, I would NOT be able to use it, which f'ing sucks.

So my options are, live with not being able to use Band 12, or else get the HTC 10. I have to think things over.
[Sony Xperia X Performance Questions & Answers] km8j:
Without volte, the phone cannot use LTE while you are on a call. These are not new pieces of information. This is how it has always worked with T-Mobile
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Well they said it can, but only the data, which I could give a flying f*ck about. The voice part requires VoLTE in order to utilize Band 12, but the other (higher bandwidth) bands don't require VoLTE to work for voice. And again, the tech support lady made a call in her area which she verified ONLY had 4G LTE with VoLTE off, and it still worked.

But this issue with not being able to take advantage of Band 12 in my area once it's activated like 6-8 mos from now really p's me off. I HATE when other people's phones get a signal and mine doesn't. Band 12 was going to be the solution to that, but now if I get this f'ing phone I won't be able to enjoy that feature. Or I get the HTC 10 and it has all that but the camera isn't as good as my overrated S7 or the XP's even better camera. I have to think this through some more.
[Sony Xperia X Performance Questions & Answers] km8j:
HTC 10 is awesome but I was really looking for a phone that was, you know, usable with one hand. I don't understand the trend of these huge phones. Makes no sense
[Sony Xperia X Performance Questions & Answers] RockStar2005:
I couldn't agree more. Phablets are lame. I had the S7 Edge like 2 weeks before it's release date (pre-ordered early), and even though it was really cool in a lot of way, I just couldn't get over the size of it. And that's only a 5.5" phone. My cousin has the Note 5 and I don't know how he even fits it in his pocket.

Yeah Sony put their fingerprint sensor on the side so one-handed usage is more possible. But HTC puts there's on the front. One thing I was happy to find out on the HTC 10 while playing with in a store is that even though the front home button looks like a (lame) physical button, it's ACTUALLY doesn't press in. So in reality it's just another virtual home button........like Sony. :good:

I feel like whichever phone I get I won't be fully happy with it. With the XP I have the great camera but reception-wise I'm gonna stuck in 2015 forever cuz can't utilize Band 12. lol I really hate being forced to decide between the two, because I really shouldn't f'ing have to.
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Guys,

So someone in another thread told me that the DUAL-sim version of the XP is very likely to have VoLTE. He's in Hong Kong, and said they will be getting the dual-sim version of the XP sometime this month (vs. the single-sim one that comes out most likely next month here in the U.S.). He said he will try it out in a local store to see if it does in fact have VoLTE or not, and then let me know right away. Apparently I can order it from Expansys' Hong Kong site, which I believe delivers to the U.S.

Let's say that he's ACTUALLY right and that version has VoLTE. Is there any reason to believe it wouldn't work still here?? I read something before about T-Mobile needing to certify VoLTE or whatever stupid BS, so not sure.
[Sony Xperia X Performance Questions & Answers] km8j:
Won't work on T-Mobile unless certified. If you try and ask T-Mobile they will refer you to Sony and vice versa
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Yeah I got it all straightened out. I'd have to be on AT&T for it to work b/c they don't require that certification.

After finding all this out, AND that I can't get phone insurance on it b/c it's unlocked, I've decided to just go ahead and buy the HTC 10 through T-Mobile. Sony Mobile has made a great phone, but they also have made this WAYYYY too much of a hassle for me. HTC cares about their customers (and has made a GREAT phone too, which in some ways is better than the XP), while Sony Mobile CLEARLY doesn't give a F. So F them. lol If they ever decide to get back with T-Mobile, I'll reconsider them. But I'm done with all this nonsense.

Thanks guys for all your input.
[Sony Xperia X Performance Questions & Answers] RockStar2005:
So I got the new INT'L VERSION of the XP TODAY! Love it!! But a few questions guys................

1) When the phone is on a call, instead of going to 4G (since no VoLTE, which we'll discuss in a second lol), it goes to 3G. Why is this happening? I know it's the int'l version and all, but is there a way to alter it is so that it STAYS in 4G?? Any "flashware" that doesn't require unlocking the bootloader or rooting??

2) Also, is there any flashware to put VoLTE on this phone? I know some foreign versions of the XP have VoLTE, but apparently the int'l version does not.

3) I'd downloaded the phone settings automatically using an option in Settings. So that went well. Phone calls and texts are coming through fine now. I notice though that when in LTE, it doesn't say 4G LTE, just LTE. Is that normal? Does that mean 4G LTE???

Thanks everyone!
[Sony Xperia X Performance Questions & Answers] km8j:
LTE is 4g LTE. 4g is all marketing gimmick. You are falling back to hspa or hspa+ which is 3g. It's not really 4g and just depends on the firmware you are using. Don't let that icon confuse you. Nothing you can to fix Sony's huge mistake by not certifying this phone
[Sony Xperia X Performance Questions & Answers] RockStar2005:
hey km8,

Ok that's what I thought it was from what others have said to me recently regarding 4G LTE. So that's fine.

I've seen hspa or hspa+, but 95% of the time during a call it's at 3G. But what does them certifying VoLTE with T-Mobile have to do with it? It doesn't even have VoLTE anyway, which means it SHOULD simply go down to 4G during a call the way my parents' Z1s (no VoLTE either) does. It just doesn't make any sense. The certification was just to have Band 12 in LTE for data during a call. But it should go down to 4G in this case, not 3G.
[Sony Xperia X Performance Questions & Answers] km8j:
That's what I'm saying. 4g and 3g in this case are the exact same thing. Years ago before LTE was prevalent, everyone was calling hspa 4g and it isn't. Depending on the firmware and properties, that drives when the signal shows what. Some phones just say 4g for everything, including LTE. Hspa and hspa+ is the same technology just faster. It's like comparing different speeds on your cable modem whereas LTE is actually a different technology than said cable modem. My point about certifications was just that you cannot get T-Mobile USA VoLTE on this device
[Sony Xperia X Performance Questions & Answers] RockStar2005:
km8j,

So WAIT lol....... are you actually telling me that even though it SAYS 3G during calls on my XP that I'm ACTUALLY getting 4G still??!! Please be VERY clear km8j! lol Also, please explain how you know you're right.

HSPA and HSPA+ are FASTER than 4G, or 4G LTE? Don't know anything about those 2. Is T-Mobile even compatible with HSPA/HSPA+?? Or are those int'l only?

Ok on VoLTE, I guess. lol
[Sony Xperia X Performance Questions & Answers] kms108:
From reading through some of your post, May be you should do some research on these information on mobile data speed and various types on data and their speed, it seems that you are getting mixed up and not understanding what they are.
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Dude, just tell me.......... am I ACTUALLY getting 4G during calls or is it in fact 3G? That's ALL I wanna know right now. Forget HSPA.....that's old news.
[Sony Xperia X Performance Questions & Answers] kms108:
if don't have VoLTE, it's 3G.
[Sony Xperia X Performance Questions & Answers] RockStar2005:
But again, my parents DON'T have VoLTE on their Xperia Z1s phones either, yet they STAY in 4G during calls. So again, I'm not understanding from you why that is.

To be more specific, during calls, it actually switches back and forth from 3G to H+ (aka HSPA+).
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Someone in another forum said this:

H+ it's 3.5G, but AT&T and T-mobile mislead people saying that H+ it's 4G, there seems to be a loophole and they took advantage of it.

I GUESS I can live with that. lol But it's still kinda BS. Apparently there's more to it than just the VoLTE-certification, b/c my phone is no different than the T-Mo Z1s EXCEPT that it's unlocked and int'l.
[Sony Xperia X Performance Questions & Answers] km8j:
There is no more to it than the certifications. Hspa is NOT 4g, it is 3g. Stop worrying about the name. The only significant difference is LTE as it is grossly different technology.
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Well yeah, obviously there's more! lol I realize that now! lol

A few ppl have said it's actually like 3.5G, so I guess that's improvement? lol

3.5G + 3G is a lil better at least than JUST 3G.
[Sony Xperia X Performance Questions & Answers] Bialynia:
I get LTE with Tmobile in Chicago with this phone
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Hey Bialynia,

I do too, but do you get it DURING phone calls?? That's the issue right now. Let me know.

I spoke to T-Mobile's Tech Support ppl a few days ago. They said that once the Band 12/700 MHz spectrum they just purchased (from an AT&T subsidiary) a few weeks ago gets deployed (prob 3-6 mos from now), everyone anywhere near Chicago will see an upgrade, and that during calls the XP does have the right band to get 4G as well (Band 12). Though on this int'l phone I wonder if it will show up as LTE or not? Anyone know??! She said right now the XP can only use the 3G/H+ (H+ = 3.5G) band (Band 2, 1900MHz) during calls b/c it doesn't have the 4G one (Band 2, 2100 MHz), but that once the Band 12/700 MHz gets disbursed, we can start using that too for 4G during calls. So just be patient I guess. lol
[Sony Xperia X Performance Questions & Answers] km8j:
You will not be able to use this phone on VoLTE until Sony certifies it which they won't do
[Sony Xperia X Performance Questions & Answers] RockStar2005:
km8j,

The phone doesn't have VoLTE, but the T-Mobile Tech Support rep said that the only reason I can't get 4G (NOT 4G LTE, which WOULD require VoLTE) right now is because the only phone call band the XP has that's compatible with T-Mobile at this time is the Band 2/1900 MHz one, which is 3G/H+. The Band 2/2100 MHz one is the 4G one for T-Mobile in my area, but the XP doesn't have it. She further explained that once the area in and around Chicago gets Band 12/700 MHz (approx. 3-6 mos from now), that since the XP DOES have this band that I will at that point start seeing phone calls get handled in 4G (finally). I mean, it makes sense to me. If she was wrong, then we'll find out. But once again, my parents' Z1s doesn't have VoLTE but does make calls in 4G, not 3G/H+. And they live not far from me too. I had given her the gsmarena page on the XP so she could check the Bands, and from there she was able to determine all that info.
[Sony Xperia X Performance Questions & Answers] btort1:
So basically the international version of the XP can't get LTE on T-mobile's network in the US. I was thinking about getting this phone because it's the only phone that has flagship specs that's not a stupid phablet AND the US version gets no fingerprint sensor. The S7 and z5c are the only phones that have a 5 inch or below screen.

I guess I'm gonna have to wait till october for the new nexus to comes out, I own a HTC 10 at the moment but the upgrade to 5.2 inches made it just barely bearable to use in one hand. 5 inches is really the sweat spot for me since I use my phone one handed 90%of the time.

I hate phablets because they take so much space in your pockets, and seems easier to break their displays.

F apple for creating this phablet hype, ever since the 6 plus came out, oems chose to make their displays bigger :( before we ACTUALLY HAD choices of 5 inches and 5.7 inches in notes, now EVERYTHING is 5.5 inchs or bigger...
[Sony Xperia X Performance Questions & Answers] RockStar2005:
brort,

No it CAN & DOES get LTE (or 4G LTE), but just not during calls. When not on a call I get 4G LTE all the time in my area. It's just during a call I don't. But I don't know if the US version will have VoLTE or not? Does anyone know?? Even if it does, unless Sony certifies the VoLTE with T-Mobile, it will still stay at 4G (aka H+/HSPA+ on the int'l phone) during a call.

To me, I don't notice a difference and calls sound very clear even on 3G/H+. And if your area has Band 12/700 MHz spectrum already (check here to see, scroll down to map), then your calls will be in 4G/H+. I'm in Chicago which will get it in 3-6 mos, so coming very soon. You may already have it though since most of the country now does per that map.

Yeah phablets suck! lol My max is 5.2" maybe 5.3". Anything above that to me is a phablet. I think you should seriously consider the XP. I LOVE this phone! The camera on it is EVEN BETTER than the HTC 10's and even the S7's. I had both so I know. Its pics are more detailed than the 10's and more color accurate and natural looking than the S7's, which tends to oversaturate certain colors. Just remember to change the resolution from the default 8MP to 23 or 20MP. Plus it's beautiful with the backside brushed aluminum & hairline finish (I have the graphite black one), stereo front speakers (where they belong), super fast UI, really nice screen (looks as sharp as any 2K screen to me), etc. I bought mine from NGP on Amazon (see Other Sellers on right side. They have the best price). Great seller. See my review too. Also got this sweet clear case for it.
[Sony Xperia X Performance Questions & Answers] btort1:
I live in bay area, 30 mins from san francisco and we still don't have band 12. Can you tell me your exact model number so i can look up which bands it supports for tmobile. Can you show me speedtest on what speeds you get on lte?
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Yeah it's F8132, dual-sim int'l version of XP.

Also, you can check here.

Ookla speed test results from my home (4G LTE): Download - 30.01 Mbps, Upload - 27.26 Mbps

As I said, I get 4G LTE when not on calls, but during calls no. But that will change soon, and prob for you too. At the very least on XP you will get 4G once Band 12 is deployed in your area.
[Sony Xperia X Performance Questions & Answers] km8j:
This will NOT change unless Sony certifies the device which won't happen. They don't care about USA. You also are not getting HD voice fyi or evs.

I REALLY want this phone but not sure I can go back 3 years in technology.
[Sony Xperia X Performance Questions & Answers] btort1:
Turns out i might not be on tmobile that much longer, 3 months tops and I don't really care about band 12 or voice lte anyways. Is the dual sim version missing any important tmobile or at&t bands or frequencies?
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Yeah I know all that about HD Voice (what's EVS?). Again, you don't need VoLTE to get a 4G (aka H+) signal during a call. The only signal I get for calls in my area is the 3G/H+ one. But the T-Mobile Tech Rep said if I went somewhere where Band 12/700 MHz was ALREADY disbursed (for me, that's still 3-6 mos away), my calls would STAY in 4G or H+. So I think you're thinking of 4G LTE. You DON'T NEED VoLTE to stay in 4G or H+, it's only for 4G LTE. So the certification issue doesn't apply here. No, I won't get 4G LTE, but I'm fine with that. Calls sound very clear to me anyway and going to H+ will prob improve it even more.

I don't think you should let the call thing stop you from buying this phone, esp if you already live in an area where Band 12/700 MHz has been disbursed (check map). The XP's camera outperforms the S7's and the HTC 10's, it's the best looking of the 3 (though that's more an opinion lol), it doesn't LAG like the S7 does (no garbage TouchWiz), it's has 2 front stereo speakers that sound great, etc etc. I can't imagine having any other phone right now, and I had both the S7 and 10 (S7 for 3-4 mos, 10 for about a week). Other phones like the Nexus 6P are great too but way too huge (unless u like phablets? lol).

So it's up to you............................
[Sony Xperia X Performance Questions & Answers] btort1:
Problem is most, oems abandoned the 5 inch phone besides samsung with the s7, sony xperia z5 compact and now the x performance. The rest have no flagship specs. Motorola basically went from 5 inch to 5.5 inch, Lg went smaller but not small enough, and the htc 10 is barely just right. I hated the how the nexus 5x had low end specs and a somewhat laggy soc.... With a bezel the size of a 5.4 or 5.5 inch. Sony and Samsung are our only options at the moment. Samsung isn't really an option for me because touchwiz is laggy, even though the newer one is much bearable than the past. At least apple has a 4.7 inch and a 5.5 inch. At least they give us the option to choose our perfect size (even though the size of its body can probably hold a 5.7)
[Sony Xperia X Performance Questions & Answers] RockStar2005:
btort,

Yeah the trend has been that "bigger is better", much to my dismay. lol Yeah I also thought it was BS that the Nexus 5X couldn't just have been a smaller version of the 6P. It was like a joke compared to the 6P, not just smaller. I seriously considered the 5X for a moment until I saw its specs. lol If they'd just made it like the 6P, there's a good chance I may have bought the 5X instead..........maybe.
[Sony Xperia X Performance Questions & Answers] km8j:
Evs is enhanced voice services
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Isn't EVS just the title given to both HD Voice and VoLTE? Or is it separate??

Truth be told, when I compare how the call sound quality is on my XP (no HD Voice/VoLTE, or EVS) vs my now former S7 (which HAD all that), I can say without a doubt the calls sound better on my XP. The S7's calls always sounded tinny/compressed, but on my XP they sound just fine. So I dunno.......... of course those features also help keep the call from dropping, so I guess I can't discount that. But so far I haven't had any dropped call issues to talk about.
[Sony Xperia X Performance Questions & Answers] km8j:
EVS is a feature that is network and phone dependent that increases call reliability, reduces connection time and things similar

You will only notice HD quality (from HD voice or VoLTE) when you are t-mobile <> t-mobile

The biggest thing to me is losing LTE when on a call as well as calls not being able to be made over Band 12
[Sony Xperia X Performance Questions & Answers] RockStar2005:
EVS: Ok I C

HD: Ok. That makes sense b/c before I'd only notice it with other T-Mo ppl.

LTE: Yeah I dunno. But I was told yeah no 4G LTE during calls but I'd still get 4G not 3G/H+. So I guess we'd still get Band 12, just not the LTE part. This came from a T-Mo Tech Support rep, not just Customer Service. I know you keep saying that's not so, but I'm gonna just wait and see. Tired of going back and forth on this. I'll just wait and see. If it's not then it's not. To me, the S7 or HTC 10 are simply not up to par with what I'm looking for.
[Sony Xperia X Performance Questions & Answers] btort1:
The 5X was about the same size as a HTC 10 but with horrible specs, the 808 is simply weak. I seen people boast their nexus 5 doesn't lag as much as the nexus 5x. I experienced more lag than it should, so I decided to return the 5x and got the 6p. While the 6p was one of the best in 2015, the size was just too big for me and hated it after 3 months. I think the S7 would be the perfect phone for me if they let me use on screen buttons and customize it to my liking...oh and it would be awesome without touchwiz. All the stuff you mentioned like the no vlte and 3g only when you are on the phone with someone doesn't matter to me. I ended up buying the X performance from the same guy as you, I just hope on AT&T it will be just as good since I might go to AT&T in a few months. Give me a 5 inch phone with a great camera, battery and no lag, that's all I want. I hope this phone doesn't disappoint me. Been through 7 phones in 2015 (2 mid range and basically almost all flagships that came out besides note 5 since I had the S6E) and 3 flagships so far this year and hope to be the last. Also hoping the new nexus won't be so awesome so I won't lose a few hundred bucks because xperia have low resell value :laugh:
[Sony Xperia X Performance Questions & Answers] RockStar2005:
btort,

Ok so sounds like you had tried out the 6P for a while at least. Yeah I just can't do anything over 5.3". lol

Yeah I wouldn't worry about that stuff. I don't think anyone in the US can get VoLTE anyway, regardless of carrier. I'm reading that those who do seem to always live in Hong Kong or some other foreign country. I know MGSBigBoss on here said he has AT&T and also bought from same seller and he doesn't see it either.

AT&T at this time at least still has a better network than T-Mobile, so you should be fine! They just cost more is all.

I don't think it will disappoint, but dahmn, 7 phones!! And I thought I was bad with 4 in 2014! lol The camera is better than the S7's and HTC 10's (trust me, IT'S BETTER! lol). More detail than the 10's and more color accurate and not overly saturated like the S7's. Most reviews on XP's camera are done by idiots who don't change the default 8MP resolution to 20 or 23 MPs, so of course it won't look as good. I dunno how those ppl even have jobs? lol The screen is 1080p but I still think it's as nice or nicer. I saw one article that rated the XP's battery has being like 12 hrs something of web browsing where S7's was only 8 something (before battery dies). Oh and lag LOL................ XP has 3 GBs of RAM and moves smooth and fast. S7 has 4GBs and NOTICEABLY lags more. Headphone listening via MicroUSB (3.5mm port is fine) on S7 is a f'ing joke. Skips like every 3-5 min. The other night I did same setup on XP for 3-4 hours straight.........DIDN'T skip once!

Well I think it's just harder to find ppl to buy Sony Xperia phones b/c most in the US at least don't even know they sell phones (and whose fault is THAT Sony?!!!). But I'm sure if you include int'l shipping you'll get someone to buy it (resale) for a good price. I hope! lol

Lemme know what you think of XP once you get it configured etc.
