Will the Z3C work on T-Mobile US? - Xperia Z3 Compact Q&A, Help & Troubleshooting

Just curious if buying it unlocked and using it on T-Mobile would be an option? Wanting to know if it'll work with the proper bands here?

Xperia Z3 (D6616) is supposedly headed to T-Mobile US as per reports. Not sure of Z3C though. I'm almost certain that you will be able to use its 2G if you bought it unlocked. It is better to check with T-mobile what 3G bands they use and then you can look up the spec sheet of Z3C to see if that band is supported.
I had once bought the Samsung Wave unlocked from abroad and used with T-mobile. Only 2G worked flawlessly. 3G was not supported.

Z3C is shown as coming soon on their US website. I believe all T-Mobile bands are supported except for band 12 which is only on D6616.

I have an exact answer for your question, hope you like unboxing videos Tmobile Z3 Unboxing​

so pretty much like the Z1 (C6903 variant that did all USA 4G/LTE and 3G)!

That's not true, the D6616 which is the T-Mobile version of the Z3 was customized for T-Mobile and has additional memory. It also supports different LTE bands than the other Z3 models.
The international Z3 Compact should work with T-Mobile but it will not have Band 12 LTE, and probably not work with WiFi calling or VoLTE.

Well, if you have a better answer than by all means you can answer his question. I was just taking a stab at it based off of good assumptions.

I don't believe T-Mobile is getting the compact version, check this http://developer.sonymobile.com/tag/d5833/ and notice the tags at the bottom, no mention of a D5816 which should be the model of the compact TMO version, if there was one, based on D6616 being the standard size version.

It looks like this phone will be compatible up to HSPA 21Mbit, GSM and Edge on T-Mobile. It seems to be missing the 1700/2100 AWS required for T-Mobile's 42Mbit "4G"
From T-Mobile: http://support.t-mobile.com/docs/DOC-6991
In order to work on T-Mobile's network, the device must support one of the following frequencies:
850 MHz (2G)
1900 MHz (2G or 3G / 4G depending on location)
1700/2100 MHz (3G / 4G or LTE depending on location)

So you'd end up with EDGE, GSM, and HSPA 21Mbit. Wikipedia does list Band 2 LTE on 1900MHz and the D5803 variant does support Band 2 LTE but I'm not sure if that make it compatible

I think you may be mistaken. It supports the T-Mobile AWS bands, which are 1700/2100, at least on the D5803 model, which is what the UK retailers are supposedly selling. It shouldn't have a problem getting full 42mbps HSPA+ on T-Mobile's network.
Additionally, LTE Band 4 is the T-Mobile AWS LTE, so it supports that as well.
The only T-Moble frequency it doesn't support is the new 700Mhz stuff they bought from ATT (LTE Band 12), but they haven't done anything with that frequency, and likely won't for another year or so.

Yea I completely glossed over LTE Band 4, whoops. I thought to support 1700/2100 AWS UMTS the phone would have to support both 1700 Band 4 and 2100 Band 4 (which it only supports band 1 at this frequency), but I may be mistaken. And I appreciate you setting the record straight if I'm mistaken in that regard. :good:

I can understand the confusion.
Sony, and possibly other phone manufacturers, don't generally seem to list 2100MHz(IV) seperately, likely since it's "bundled" with 1700MHz(IV) for the purposes of the AWS compatibility. One without the other is largely pointless (I believe).
So by listing 1700MHz (IV), they're indicating that it also supports 2100MHz(IV). As an example of what I mean, look at the official frequency listing for the Xperia Z2, which is my current phone.
D6503
UMTS HSPA+ 850 (Band V), 900 (Band VIII), 1700 (Band IV), 1900 (Band II), 2100 (Band I) MHz
GSM GPRS/EDGE 850, 900, 1800, 1900 MHz
LTE (Bands 1, 2, 3, 4, 5, 7, 8, 13, 17, 20)
Notice how it also omits 2100MHz(IV) frequency, but it definitely supports T-Mobile AWS.
Anyway, The Z3 Compact is absolutely going to support AWS.

Thank you for not only the answer but explanation, have a :good:

Thank you all for this info. Guys. I am really tempted to purchase the z3t over the z3 but I was really worried about using LTE connectivity. I have never owned a sony phone, just my galaxy s3 so this is definitely something new for me and I am ready to try something new. I was tempted to purchase from handtech but I think I will wait a week or 2 to make sure. It is said to be available in 2 days. I want LTE, this would be my first LTE experience.

No need to be concerned.
The Z3C definitely supports T-Mobile's LTE bands, except for the newly purchased 700Mhz stuff from ATT (LTE Band 12), but I wouldn't expect to see that rolled out anywhere sooner than 8 months to a year, and then it's probably going to be present only in very few areas.
Honestly, I don't think Band 12 will be a concern for another couple of years, based on the speed at which T-Mobile initially rolled out LTE.

I have a Z3C coming for use on T-Mo in the states (going from GS3 as well). I almost didn't get it because of the lack of compatibility with LTE Band 12, but then I saw where the Band 12 coverage will actually be. Frankly, it doesn't cover my area, so I decided since it is compatible with all the other LTE Bands to go for it.
There is a great map at TMoNews that shows you just where the Band 12 coverage will be, but I can't post links yet.

I cant wait. My z3c will be here tomorrow... thanks for all the info.

HTC One have T-Mobile hspa+?

Does the HTC One have hspa+ on T-Mobile? It doesn't have the 1700 band. I live in an area that doesn't have LTE but has hspa+ and hasn't refarmed the 1900 band so I would be stuck on 2g in this case?
Yes, you would be stuck with edge (2g) until the reframed network is live. Purchase the device from T-Mobile, it will have the 1700 band

Yes, that's what I was asking. So the T-Mobile version of HTC One has the 1700 band and will work with hspa+? I can't find the specs for the t-mo version anywhere. I guess we'll know for sure when it actually comes out.

of course the tmobile version will have the 1700 band. why wouldnt they? they dont want people be on 2g speeds now...
You probably looked at the dev edition (which is a att version).
Problem with TMobile phone is the 32gb ;/
I would love to get my hands on 64gb HTC One but it doesn't have the hspa+ aka 1700 band
Now I have been told you might be able to flash a radio but it has yet to be confirmed whether this is really possible or not.
Sadly I will be force to buy a S4 because of this issue. Unless someone can confirm hspa+ radio can be flashed on Dev Edition

I really hope someone creates a mod to Enable the Tmobile AWS band on the Unlocked HTC One, similiar to what they did for the ATT Galaxy Note 2. These high end phones have the hardware to work on the the various gsm frequencies, but they come disabled. Someone was able to figure it out on the galaxy note 2, but I have been searching and I don't see anyone working on a similiar solution for the HTC One. I guess time will tell. I've ordered an unlocked HTC One, and will test to see if I get 4g LTE in Chicago which is listed as a 1900 refarmed area. The consensus seems to be that if i'm in an area that does not have 4g lte i'll be reduced to 2g Edge speeds. This my friends...would suck donkey balls.

Same here. I ordered the unlocked ONE. I live in Houston which is refarmed 1900 also with lte. Had I known my dam phone would be delayed again I would have just waited for the tmobile version.

Your last statement about 4G LTE and 2G Edge speeds isn't necessarily true. I live in LA and we don't have LTE for T-mobile yet, however T-mobile has refarmed many of their towers around here to use the 1900MHz band so that you can get HSPA+ on phones that don't have 1700MHz support (like many AT&T phones and unlocked phones, like the HTC One Developer Edition). I received my HTC One Developer Edition today and drove around a bit here. While my phone doesn't have 1700MHz support, the screen still showed "H" for HSPA+ everywhere I went, and I tested speeds as high as around 9000kbps download. So being able to get 1900MHz HSPA+ is not tied directly to if an area has LTE or not.

[q] sony xperia z1: C6903 , c6906, c6943

Hi everyone,
I'm thinking of purchasing a SONY XPERIA Z1 but I'm confused on the versions: does anyone know what would be the difference between C6903, C6906 and C6943 ?
I'm using 4G on TMobile U.S.A., so, which model will be best fit for that network and, again, what is the difference between those versions?
Thank you.
http://forum.xda-developers.com/forumdisplay.php?f=2509
Answering my own question, it seems that the only difference between the versions are the Bands and Frequencies, as follows:
Supported networks Xperia™ Z1 C6902/L39h: UMTS HSPA+ 850 (Band V), 900 (Band VIII), 1700 (Band IV), 1900 (Band II), 2100 (Band I) MHz; GSM GPRS/EDGE 850, 900, 1800, 1900 MHz.
Supported networks Xperia™ Z1 C6903: UMTS HSPA+ 850 (Band V), 900 (Band VIII), 1700 (Band IV), 1900 (Band II), 2100 (Band I) MHz; GSM GPRS/EDGE 850, 900, 1800, 1900 MHz; LTE (Bands 1, 2, 3, 4, 5, 7, 8, 20).
Supported networks Xperia™ Z1 C6906: UMTS HSPA+ 850 (Band V), 900 (Band VIII), 1700 (Band IV), 1900 (Band II), 2100 (Band I) MHz; GSM GPRS/EDGE 850, 900, 1800, 1900 MHz; LTE (Bands 1, 2, 4, 5, 7, 8, 17).
Supported networks Xperia™ Z1 C6943: UMTS HSPA+ 850 (Band V), 900 (Band VIII), 1700 (Band IV), 1900 (Band II), 2100 (Band I) MHz; GSM GPRS/EDGE 850, 900, 1800, 1900 MHz LTE (Bands 1, 2, 3, 4, 5, 7, 8, 20).
U.S.A TMobile's 4G LTE uses Band IV (4), 1700/2100 Mhz Frequencies.
So can someone tell me the difference between the C6903 and the C6943? They appear to be identical.
C6906 or C6903?
I am still uncertain as to which model would be best to use in the U.S. running 4G?

Trying to work this out too, from a couple of posts up it looks like if you're on tmobile either the 6903 or 6906 you're good but I only started looking at these the other day so it would be nice to hear from others who have already gone through this. Where I am tmobile are offering LTE service..
I think the C6903 is good if you're using T-Mobile, that's what I heard from a different post I commented on.

No, there is only a photo of the back of a Z1 with "T-Mobile" printed on it.
Here's what I've gathered regarding the differences between the C6902, C6903, C6906 and C6943 versions.
All versions only differ by the LTE frequencies they support from what I can see. Can anyone find any other differences because I sure can't?
C6902
No LTE support. Who wants that?
C6903 and C6943
These two have the same LTE frequency support (LTE (Bands 1, 2, 3, 4, 5, 7, 8, 20)). Although band 4 is used by T-Mobile and AT&T, 3 and 20 are used in other countries, so these models appear to be "international" versions.
I cannot find any difference between these two versions. Here's the white papers - can you find any difference?
http://dl-developer.sonymobile.com/documentation/whitepapers/Xperia_Z1_LTE_C6903_WP_3.pdf
http://dl-developer.sonymobile.com/documentation/whitepapers/Xperia_Z1_LTE_C6943_WP_3.pdf
C6906
This is what us USA folks want it seems. This model excludes two LTE frequencies supported by the other two (bands 3 and 20) and adds one: 17. From what I've gathered from Wiki, band 4 is used exclusively for T-Mobile's LTE, and AT&T uses bands 4 and 17.
Please correct me if I'm wrong about any of this. :fingers-crossed:
I read on another thread that the C6943 is "the Brazil version with digital television".
So I've gotten the C6903 and it is working perfectly fine on T-Mobile. I am getting LTE.

Yep, that's expected. Nice choice!
The differences between the c6943 and the c6903 are the bands and the c6943 has TV.

All versions only differ by the LTE frequencies they support from what I can see. Can anyone find any other differences because I sure can't?
C6902
No LTE support. Who wants that?
C6903 and C6943
These two have the same LTE frequency support (LTE (Bands 1, 2, 3, 4, 5, 7, 8, 20)). Although band 4 is used by T-Mobile and AT&T, 3 and 20 are used in other countries, so these models appear to be "international" versions.
I cannot find any difference between these two versions. Here's the white papers - can you find any difference?

http://dl-developer.sonymobile.com/documentation/whitepapers/Xperia_Z1_LTE_C6943_WP_3.pdf
C6906
This is what us USA folks want it seems. This model excludes two LTE frequencies supported by the other two (bands 3 and 20) and adds one: 17. From what I've gathered from Wiki, band 4 is used exclusively for T-Mobile's LTE, and AT&T uses bands 4 and 17.
Please correct me if I'm wrong about any of this. :fingers-crossed:

Yes, the C6943 Model has Digital Signal for TV this is the only difference between C6903
I'm running a c6906 on at&t, amazing lte service. Not sure about toile though, you need to check the band's.
So this may be the wrong place to ask this but I'll risk it anyway.
Even tho I think I have a C6906 may I flash C6903 FTF files onto it?

[Q] UMTS/HSPA 900 + LTE Band 20 Flash ATT S5

I was hoping the ATT S5 would get UMTS 900 and LTE Band 20 (Europe Digital Dividend 800 Mhz), I was disappointed to see that it does not.
I live 45 min. North, Northwest of Philly and AT&T is the best carrier in PA - HANDS DOWN! I also travel every week, all over the US for work - and I'm very happy with AT&T in general. One thing I noticed on my S4 is that I could not get LTE in Burlington, VT on it - but I had full bars of LTE on my iPad Air. Side question; What band does ATT use for LTE there that the S4 don't support?
Anyways,
on the S4 I was able to activate AWS freq. for UMTS by flashing it. I need to do this for UMTS 900 and/or (pref. AND LTE Band 20, since I travel to Northern Norway all the time - and there is only UMTS 900 and LTE 20 some places there.... If I cannot have the phone flashed to have the current bands AND the wanted bands - would there be a way to flashing it back and forth from ATT to "Euro/International" mode?

AT&T uses bands 2, 4, 5, & 17 for LTE. Band 17 (700mhz) is what most of their LTE is on. That's why the signal is always good. I am starting to see Band 2 (1900mhz) in some areas. I saw Band 4 (AWS) in Chicago in a few areas (probably were capacity is weak).
Yes, with the S4 you could unlock the AWS frequencies. I do not know if you could flash UMTS 900 with an S4. You will not be able to flash anything with frequencies on the S5 as AT&T has locked down the phone entirely. It will follow in the Note 3's footsteps.
I think they discourage people unlocking their devices and using them on other networks. AT&T is forgetting what GSM is all about IMO. If AT&T LTE is not that important to you, you may want to consider the international variant which will support your European frequencies. It will NOT work on AT&T LTE though.
Hope I helped.

AT&T is most important, as I am in the US 95% of the time. At least the S5 will have LTE 1800 and 2600. My hometown in Norway should get LTE 1800 later this year. So at least I will have GSM 900, UMTS 2100 and LTE 1800.
Do you, or anyone else know if AT&T will unlock Phones on the Next plan? I got the S4 full price, but I'm using the Next plan for the S5.

They'll unlock it if its paid off entirely. But that doesn't mean you can't unlock it yourself.

[Q] URGENT - Compatibility of Moto X 2014 with O2 in the UK

Hi, guys!
I am flying to the States for work and I am thinking about getting a 64gb Moto X 2014 and I was wondering if it´s a good idea.
I am living in the UK and I´m an O2 user, and according to this website, O2 has only 800 band right here:
"O2 spent £550,000,000 to secure 2 x 10MHz of 800MHz spectrum, but didn’t come away with any 2.6GHz and has no 1.8GHz either."
Moto X, according to the website, is compatible only with this LTE networks:
"Moto X - Pure Edition (GSM Unlocked with T-Mo SIM - XT1095):
GSM/GPRS/EDGE (850, 900, 1800, 1900 MHz)
UMTS/HSPA+ (850, 900, 1700 (AWS), 1900, 2100 MHz)
4G LTE (2, 3, 4, 5, 7, 17)
So, my question is... Will I be able to use this mobile here in the UK? Will I find issues with the calls, the 3g or the 4g? Any problem with the bands, at last?
I swear I have been reading this morning a lot of articles but I'm a NERD in telecommunications
I would really appreciate if you guys could give me a hand here because I´m departing quite soon
Thanks in advance!
As far as I can 4g will not work because the phone does not support O2 bands but 3g should work fine.

It is a physical limitation rather than a software one. So most likely, there is no way to change/fix it.
EDIT: It seems that 3's and EE's 4g have compatible bands so if you are willing to switch to one of them it might work.
3 supports band 3 (1800 Mhz) same with EE.

NOTE: haven't 3 proposed a buyout of O2?

Correct! I heard that 2 weeks ago and it's going to be great for O2 customers... 3 is now a HUGE company here in the UK.
It looks like I will end up getting it because it will work... And I don´t want to stay with O2 anyway
Thanks, guys!
Hey! Let´s go for the next level...
What about the Droid Turbo?
Bands
LTE Cat 4 (Bands 2, 3, 4, 7, 13)
CDMA/EVDO Rev A (850, 1900 MHz)
UMTS/HSPA+ (850, 900, 1900, 2100 MHz)
GSM/GPRS/EDGE (850, 900, 1800, 1900 MHz)
Carrier Aggregation (B4+13)
Any idea? I already decided to leave O2 and go to EE or 3, will I be able to use it with 1800 band?
Thanks again!
The Turbo have band 3, which should be compatible with 3 and EE, BUT I think it is carrier locked to Verizon and I am not sure if you can unlock it or not.

[Q] Xperia Z3+ Dual - US - T-Mobile Compatibility

All -
I have been eagerly awaiting the release of this phone in the US and was surprised that Expansys USA listed it on their site on Monday 23rd June as a DUAL SIMM model.
I called them to verify that they did in fact have the phone in stock. In that conversation I realized the one they have seems to be the European Model and does not support T-Mobile LTE in the US. To clarify the maximum speed you can get on the E6533 is 3G on T-Mobile's network.
This brings me to my question and please indulge me if it has already been answered elsewhere: Will there be a US version of the (Xperia Z3+ -E6533)that is slated to be released and if so does anyone know if if it will fully support US T-Mobile 4G LTE.?
Any information would be greatly appreciated. Thanks Much.
What gave you the impression that the E6533 won't get more than 3G on T-Mobile? According to GSM Arena, that specific model has B4(1700/2100) and B12(700), which is what T-Mobile primarily uses for LTE. If the information is correct, you should have no problem connecting to T-Mobile's network.

T-Mobile is phasing out their 1700Mhz 3G band soon so it won't really matter.
I should be receiving my Z3+ by Wednesday. I'll let you guys know how T-Mobile performs on it. I ordered the single sim, E6553 version.
Sent from my Nexus 9 using Tapatalk
Please do! Also check the 3G compatibilty beside LTE. Since Culex316 said 1700 MHz 3G being phased out, it should be fine. Like OP, I was also initially planning to get the E6533 (Dual) as I have a tmobile sim too (micro). I ended up getting the E6553 to use on my ATT line as the white paper says dual sim version LTE DL is limited to 150 Mbps (vs 300 Mbps on the E6553) & the dual sim also doesn't support quick charge 2.0 just yet.

I should be able to report my findings on Thursday. Have a date with the lady friend on Wednesday so I probably won't do anything with the phone until Thursday. First few charge cycles suck and i don't want to end up with a dead phone in the middle of a date.
But I didn't know that there dual sim version didn't have quick charge yet, that's interesting. I'm not too bothered by LTE speeds honestly, but connectivity is always a concern.

No, they are refarming the 1900Mhz spectrum from their 2G EDGE network to LTE.
Band 12 is a different frequency altogether (700Mhz A block).
I came to the sad realization that if you're on T-Mobile, you can't quite have your cake and eat it too with this latest Z3+ situation. I was so excited and almost ordered the E6533 dual SIM version off eBay and the seller "NeverMSRP" where I have bought from many times listed the dual SIM version as having both band 12 and AWS HSPA+ compatibility. I know the latter isn't widely deployed still, but I wanted the dual SIM option and that was icing on the cake. Then I saw conflicting reports and noticed Sony's own whitepapers did not have band 12 listed on the E6533. Sure enough, I think the eBay seller was reporting the incorrect frequencies. Total bummer. I don't want to buy anymore T-Mobile phones without band 12 as I think late 2015 is really when it's going to shine. Anyway, be careful of eBay.

Honestly, I've never been too fused about LTE speeds, as long as I have HSPA+ I'm happy.
But a preliminary report on the E6553 - it connects to T-Mobile just fine for now. I started this phone up a few hours ago and have it set up now. My home is a horrible spot for T-Mobile, but I'll be out and about tomorrow so we'll see the connectivity.

Been out and connectivity to T-Mobile's network everywhere has been great!
No issues with voice calls or anything. The E6553 is definitely a great choice for me. I've also been getting great battery life too. I'll report what I've got in the battery thread

Refarming 1900mhz doesnt mean the LTE spectrum will end up at this spectrum. The converted spectrum will be at band 12 700mhz from EVERYTHING I've read.
E6533 - Didnt work with T-Mobile LTE?
Colin -
If I am reading your post correctly, the DUAL SIMM version you got from "NeverMSRP" did not work with 4G LTE on T-Mobile? Ironically that is the same dude I been emialing and he swears it works. Kindly advise.

Its very simple just search google for "Sony Xperia Z3+ E6553 white paper" for Single sim version and "Sony Xperia Z3+ E6533 White Paper" for dual sim version. Check if LTE band is there in company's product datasheet... don't believe on sellers from ebay ...they copy stuff same for all mobiles...

yes it's also very simple to see that it was provided earlier, but this guy's experience seems to be a bad one, and we're trying to confirm his personal experience instead of some sheet nobody has confirmed working on t-mobile yet. So unless you don't have your own personal confirmation why don't you google something else for yourself.
