kms,

Yeah I've already confirmed the XP has Band 12/700 MHz capability, so don't worry about that. But getting a version of the XP that HAS VoLTE would be VERY important to me! I HATE it when other people around me can get reception indoors but I can't (it doesn't happen often, but it does happen). Having VoLTE would most likely eliminate this from happening the majority (if not ALL) the time.

That's fine. The one from the store will be the same as the dual-sim one from Expansys HK anyway.

So THIS month?!! :D:good::victory: That's f'ing awesome!!! Yeah we won't get the the single-sim XP here in the U.S. 'til I dunno, early to mid July? So even if I have to pay more for dual-sim, to have it extra early and WITH VoLTE would be extraordinary!! Man I REALLY HOPE the dual-SIM version of the XP has VoLTE!

Ok so say it does have it...........is there any reason to think it might not work here in the U.S. kms??!
[Sony Xperia X Performance Questions & Answers] kms108:
HK expansys is likely to get the Hong Kong version, it's also a 64GB version, the only reason for not working in the US is the band, the band is 700, but there are various version of the 700 band, so not sure if this is the band 12.
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Ughh you're right about the dual-sim one having 64 GBs! I don't need the 64GB version, like I don't need the extra SIM slot lol, but F it, whatever. IF this f'ing phone ACTUALLY has VoLTE on it, then I'll buy it. FML lol

Well wait a minute. There's a Hong Kong version? I don't think so kms..........the single-sim one I pre-ordered from Expansys US is the INTERNATIONAL version. Expansys US' own customer service people told me that they ONLY sell the international versions (unless otherwise noted). So I think the one you guys are getting will be the INTERNATIONAL version kms, but it'll be sold there in HK. Both the single and dual SIM versions of the XP (F8131 & F8132) have Band 12/700 MHz. So I don't see why it would be any different here vs. in Hong Kong to be honest with you.
[Sony Xperia X Performance Questions & Answers] kms108:
If you can confirm the information is correct, then it's ok, extra internal memory is bettery, even 32Gb is getting slightly small these days, so the more the better.
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Yeah but I already HAVE a 64 GB MicroSD card in my phone now, so I don't need the extra room, and won't be using it either.

Confirm what information kms??
[Sony Xperia X Performance Questions & Answers] kms108:
If the information about the version you are about to get is correct, thats what matters.
[Sony Xperia X Performance Questions & Answers] RockStar2005:
You mean the single-sim one I pre-ordered, that it IS in fact the international version?? If so, I've already confirmed that with Expansys US. They told me they only sell the int'l version of phones UNLESS otherwise noted. Here is a copy & paste of their e-mailed response to me on that topic:

This would be the international version, please let us know if you have any other questions.

Regards,

Dulce

So kms, if that's what they sell, then the dual-SIM (F8132) model YOU'RE getting will also be int'l, so it will come with Band 12/700 MHz capability on it as well, which that page I linked you earlier confirmed. What I don't get is why the F8132 would have VoLTE on it but the single-sim F8131 wouldn't? But if your prediction is true, then I don't give a sh*t. lol I just want that f'ing phone!! lol
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
Volte won't work unless sony actually certifies the process with the carriers they intend to have it with. Volte will not work like the z5 didn't.
[Sony Xperia X Performance Questions & Answers] RockStar2005:
F. Ughh......... lol.

So the unlocked Z5 had VoLTE on it but it still didn't work here in the U.S.??
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
Correct. Anything that has LTE bands and Android 5.0 and up has volte capabilities
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Ok.

So what do you think MGS? Get the XP with the best camera but can't utilize Band 12 for voice on a call (so can't benefit from its improved indoor reception advantage) & no HD Voice, or get the HTC 10 which still has a very good camera and has the Band 12/VoLTE/HD Voice advantage? Tough choice, for me anyway.
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
Ethically I'd say htc 10 as htc wants your money as they listen to their fans for the most part and go the extra mile supporting all carrier features. On the other hand I'm a big sony fan and enjoy the value of their hardware but let's be honest sony really doesn't care about us. They force us to buy international versions to get full features and gimp us phones without giving us legitimate reasoning. Have you ever talked to sony mobile support they are as clueless as we are.
[Sony Xperia X Performance Questions & Answers] RockStar2005:
You make some valid points MGS.

The fact that HTC STILL sells their phones through all the major carriers is an advantage all its own. I can go onto T-Mobile's website and buy the HTC 10 RIGHT NOW if I wanted to.

Yeah I mean, I can't lie, I love Sony's Xperia phones the most. But I am at wit's end here with all this hassle I have to go through to buy the d*mn thing, and then in dealing with the BS that comes with the actual phone. The int'l version is cheaper (yet better) and is coming out sooner than the U.S. version, so I don't really care about that. But this VoLTE thing really p's me off cuz I won't get the BEST reception with it even though I really should. Plus having to buy it unlocked is dumb too.

Oh dude, JUST the other day I spoke to them. They LITERALLY know nothing more about why the supreme morons that run that company do what they do than we do. Is it really THAT hard to get the phone certified? I mean, if you're not gonna offer people the chance to pay for it on a monthly basis (like carriers do) interest-free, and not release it on time (f'ing July??!), the LEAST you could do is go that extra mile and get the d*mn thing certified for VoLTE and HD Voice too.

So your answer is HTC 10 or XP? lol
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
I really don't know yet. I'm tempted to just stay with my z3v which has volte and hdvoice on verizon lol
[Sony Xperia X Performance Questions & Answers] RockStar2005:
lol yeah. I hear that. If I had my Z3 still I'd prob just keep it.

Well if you were me, and keeping the S7 IS NOT an option lol, 10 or XP? lol
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
Well you seem to upgrade phones quick, and is a sin you traded your xperia z3v in for an Samsung. Value wise the htc is worth the money. If it was hardware value only then I'd say the xp. Wiry htc still being almost on part in that department to

---------- Post added at 03:28 PM ---------- Previous post was at 03:26 PM ----------

People with the same tmobile service you have are going to laugh at you when they are making calls volte no problem and your Xperia performance is stuck on band 12 with no calling ability and then they're going to say why did you spend that much money on a phone that can't make phone calls in all the right places. Your phone won't get better as t mobile gets better
[Sony Xperia X Performance Questions & Answers] RockStar2005:
I don't know about "quick". lol I mean, I went a year and a half with the Z3 (not Z3V) with T-Mobile before changing to the S7. I tried out Samsung only b/c Sony had announced the end of the Z series around that time (late Jan/early Feb), so I thought they were done with making flagships. Initially they made the X series sound like a bunch of mid-rangers, but then I took a closer look at the XP's specs and decided it was still good enough to be called a flagship. But that was

after

I bought the S7. I wanted to give Samsung another chance after being unhappy with the S5 (which I only kept for 4 days lol) for these reasons: the S7 was very highly rated (now I would call it highly OVER rated lol)..........it came with a bunch of sweet promos like free Netflix for a year, etc..............and I found an app that would make the lame physical home button into a virtual button. Problem is, it only works like 60-70% of the time, which is unacceptable. But I didn't know that b/c initial testing made it seem more solid than it actually is. So my decision to JUMP my Z3 for the S7 came from misinformation really.

---------------------------------------------------------------------------------------------------------------------------------

Yes I know. lol That is the part that bugs me........ that I won't be able to do what I've been waiting for and take advantage of Band 12, esp now that it's FINALLY being prepared for implementation in Chicago. I mean, you're so right about HTC going the extra mile for the customer where Sony won't......... this article confirms that HTC even got its unlocked version of the 10 certified for VoLTE with T-Mobile, which means users can take advantage of Band 12 AND HD Voice as well. Now THAT'S customer commitment! lol

Now wait, wouldn't I still get the other bands while indoors with the XP that don't need VoLTE?? I know they're not as good as Band 12 in that situation, but I mean, I make indoor calls now and my area doesn't have Band 12.

I could go back on like Amazon and buy the T-Mobile Z3 once again, but I feel like that's taking a step back, esp after having the S7 for 3-4 months now. And I don't know that the Z3's camera would be any better than new HTC 10's either.

Thanks for your input. I'm going to go check out the HTC 10 again (did at Verizon, but will this time at T-Mobile in case there are any small differences), and then decide.
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
Htc is almost on par in the hardware value department. So on paper htc wins everytime. I mean why make a us model and not get some certifications.
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Exactly. If the U.S. XP had VoLTE-certification with T-Mobile, I MIGHT be ok with no fingerprint scanner or IP65/68. But we both know it doesn't. lol

Do you think since the unlocked version of the 10 is VoLTE-certified by T-Mobile too that there's any advantages to getting it over the T-Mobile version?? I know the unlocked one will get updates faster, but then what if those updates don't fully take advantage of T-Mobile's network the way an update on the T-Mobile HTC 10 would?
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
Na the unlocked version is the way to go. Once certified volte won't be messed with. Now you got me thinking of it lol
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Haha nice!

Well give me some reasons why the unlocked version is better than the T-Mobile one, besides the ones I've just mentioned, if any?

I meant like if a future update comes to the HTC 10 would T-Mobile's "version" of the update work better on T-Mobile's network than the original HTC version?

Looking at this pretty recent camera comparison and review, for the most part, I feel like the camera on the HTC 10 (this being the newly updated version) is actually better overall vs. the S7. THAT makes me happy. LOL And future updates will make it even better I'm sure.
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
Unlocked means updates quicker and no carrier bloat. If t mobile has something to improve connectivity then it's up to htc to include that in their updates which it will be easy to do small updates on unlocked devices.
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Yeah ok. I did know all that. Nice.

Here's the one thing though......... I really want the silver 10 with the front bezels to be black not white, but Amazon only has the white-bezelled ones. T-Mobile has the black one too, but that's the T-Mobile one. lol Hmm.............. ok when I go onto HTC's site, they have the black-bezeled silver one. So I guess I may get it from there. Gonna go in a bit to T-Mo and check it out first.
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
Or we can wait until the xp releases and see if sony makes some announcement if getting certifications
[Sony Xperia X Performance Questions & Answers] RockStar2005:
LOL.........ughh. More waiting?!

I dunno man........... it's f'ing June already. Do you really think there's any chance they'll ACTUALLY do it??

I don't think I could buy the phone and then sit around HOPING they will do that. Could you?
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
Slim to none but I thought they would learn after the z5. Htc 10 isn't waterproof which is a downer
[Sony Xperia X Performance Questions & Answers] RockStar2005:
I don't think I could buy the phone and then sit around HOPING they will do that. Could you?

Yeah 10 isn't waterpoof. That does suck you're right.
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
I'm curious, if I buy the xp dual and have one t mobile sim for phone and the 2nd for data. Would I then technically have volte? Do dual sim phones use both Sims simultaneously?

I'm talking 2 sim cards in one phone. One handles calls and the other volte.
[Sony Xperia X Performance Questions & Answers] RockStar2005:
I guess? But you're still dealing with two phones. lol And the simple phone may not have some features that the XP dual or other smartphones would have.

Oh yeah, the HTC 10 isn't waterproof, but I had read before that it IS splash-proof at least.

I got sidetracked and couldn't make it to my T-Mobile Store in time to check out the 10 again. So I'll have to try this week sometime.
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
I'm talking the dual sim variant. Having 1 sim for voice and the other for data LTE. In the same single xperia performance
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Ok I reread what you said and I think I understand.........but I have no idea if that would work. What do the SIM cards on the phone have to do with the phone being able to utilize VoLTE in a 4G LTE-only Band 12 area?
[Sony Xperia X Performance Questions & Answers] RockStar2005:
If you by chance confirm that your idea would work, let me know via this thread ASAP please. lol
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
Just this moment I found info confirming the X performance dual is a dual standby and NOT a dual active. So when one sim is in use the other is deactivated. So it wouldn't work. Inky way to get volte is to set up a Google voice number and have ppl call that lol and forward your number to that lol
[Sony Xperia X Performance Questions & Answers] RockStar2005:
I see. Ok. Thanks for explaining.

F that. lol I'm not changing my phone # because Sony is run by first-class idiots. lol

I'm reading more and more official reviews on the HTC 10, and right now I am SLOWLY leaning towards it. Amongst many things, the fact that HTC certified VoLTE with T-Mobile on its UNLOCKED 10 (and Sony didn't) really scored them a lot of points with me. The dumb idea of putting the fingerprint sensor on the front instead of the side or even back though doesn't help them much with me, even if it still is a virtual button. It still makes the phone look like a Samsung or iPhone to me. But I'm getting to the point where I really believe there is no perfect new flagship phone in 2016.
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
Att might be best place to use an xperia performance. No Compromised bands or anything
[Sony Xperia X Performance Questions & Answers] RockStar2005:
What do you mean? If Sony's idiotic execs (I love ripping on them SO much lol) didn't get VoLTE certified with T-Mobile, then why would it work on AT&T if they didn't certify it with them either??
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
I'm saying that calls will always work with att where there's service as for t mobile it'll work only 90% of the time lol. No volte regardless. Lol.
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Ok but why would they work better on AT&T? I don't understand.
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
All of att bands are supported for calling. So it works 100% of time but you won't have LTE while on call.

T mobile needs carriers to certify to use band 12 to call. So xp won't work for calls in band 12 areas but will work for other bands hence the works 90% of time.
[Sony Xperia X Performance Questions & Answers] RockStar2005:
So you're saying I'd get to use Band 12 FOR PHONE CALLS w/o needing VoLTE on the AT&T network for the XP?
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
Yes
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Ughh.............YET ANOTHER HASSLE. It's nice to know that AT&T isn't as stingy about this topic as T-Mobile is, but man I LOVE T-Mobile. But I guess it comes down to who do I love more, (stupid idiotic) Sony with very NOT stupid or idiotic phones, or T-Mobile.

You're 100% sure about this?? How did you find this out?
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
https://m.reddit.com/r/SonyXperia/comments/3nzcvu/does_the_xperia_z5_work_on_tmobile/

Same bands as the z5
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Hmm ok.

I don't get this part: The Z5 does support band 12, but it does not support VoLTE. Not really a huge deal, except in the hypothetical situation where you are on band 12 with no other bands available, and you need to make a call. The call will fail because there are no other bands to fall back on.

I guess that situation is when you're not getting a signal b/c the other bands can't penetrate through the wall (for indoor calls) the way Band 12 can?

I can't believe it's come down to this........... leave T-Mo for more pricey AT&T but get to use XP "fully", or stay with T-Mo and get the HTC 10. lol I really HATE Sony for making me have to choose. REALLYYY.
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
Band 12 on t mobile is only volte there is nothing lower than LTE in that band for the phone to fall back too. Hence no calls
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Yeah I FINALLY get what u guys mean........... you're talking about being in a situation where ONLY Band 12 is getting through and the other (higher) bandwidths are not. Ok.

So what's crazier? Using the HTC 10 on T-Mobile or the XP on AT&T and having to pay more for less (which I'm SURE will be the case)? lol
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
Lol that's the dilemma. It is entirely possible for Sony to patch in the support other phones have done it. The question is would they. They could get the z5 and xp in the same patch to support t mobile features.
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Yes it is a dilemma, and it's drivin' me NUTS MGS!! lol

Here's the thing.......... the Z5 came out HOW many months ago? Like 8-9? And as far as you or I know, they STILL haven't thought to release a patch with regards to the VoLTE certification with T-Mobile? Doesn't give me much confidence with regards to holding my breath for those schmucks at Sony Mobile. lol

2 things that make me further want to get the 10 are:

1) I noticed on the HTC site I linked you earlier to buy the 10 that if you scroll down a little that HTC actually DOES give you the option to buy the UNLOCKED 10 in monthly installments via PayPal (not sure if there's a fee though or not?).

2) Instead of being lame like most phones (even Sony) and relying on the 820 chip for the audio, HTC decided to go the LG V10 route and also use a SEPARATE PREMIUM AMP/DAC chipset for the 10! This separate chipset is being highly praised from what I've read. I even just got word from a friend on Head-Fi (forum for audio experts and music lovers) who had the V10 that to him, even though he loved his former V10, he felt strongly that the 10 sounded EVEN better and so he now has replaced his V10 with the HTC 10! I'm an audio guy myself, so for me, this is a BIG + for HTC vs. Sony. I use my $300 Oppo HA-2 amp/DAC right now in b/t my smartphone and my AKG K550 MK II headphones, but with what I read and was just told by my Head-Fi friend, there's a VERY strong chance that if I got the 10, I could sell my HA-2 and not have to use an in-between device anymore. (Of course, I would need to compare the 10 vs the HA-2 myself first, but still, VERY promising. lol)

But still, this is a hard choice. lol Having to use the HA-2 is not a big deal to me anymore as I'm used to it.
[Sony Xperia X Performance Questions & Answers] RockStar2005:
GSM,

Someone on the gsmarena site suggested I contact T-Mobile and see if they can somehow send the VoLTE-certification to my phone. Is that something that can even be done?? He said the XP has the support for VoLTE built in ("So I believe its up to network providers to provide it, and manufacturers to put support for it into the phone, as in support of needed codecs, which Sony has (as stated so in X Performance white paper)))". Should I even bother asking T-Mobile about this? Or does the phone need to have VoLTE activated by Sony themselves??
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
You can call them and they and ask but I doubt they will certify phones on a individual basis. If it was that easy people with Z5s would of already done it
[Sony Xperia X Performance Questions & Answers] RockStar2005:
Yeah that's what I was thinking too. lol I guess I can a chat with them.

So you know for certain that the Z5 (or any version of it, including Z5P & Z5C) never got that "VoLTE-certification" update/patch then?
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
Yes because I would of gotten one already if it did. I'm curious does the xp have band 4 and 13 LTE support (Verizon)
[Sony Xperia X Performance Questions & Answers] RockStar2005:
You would've gotten one? I thought you said you have the Z3V? Do you also have a Z5?? lol

Yes it does have both, but the XP is a GSM-only phone, so it's ONLY gonna work on like T-Mobile & AT&T's networks.
[Sony Xperia X Performance Questions & Answers] MGSBigBoss:
Well if it has those bands it'll work on verizon LTE but still no volte.

No I don't have a z5 but I would have upgraded to it if it supported and went through certification as any serious unlocked phone should do.
