[q] sony xperia z1: C6903 , c6906, c6943 - Xperia Z Q&A, Help & Troubleshooting

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.

I use my C6903 on T-Mobile and get LTE. I live in the States.

It was leaked two days ago that T-Mobile USA will carry the Sony Xperia Z1.

Do you know what version they will be carrying?

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_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.

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?

What bands does the Xperia Z have?

I'm seeing a lot of conflicting information Throughout the internet. Does the Xperia Z have the required bands to operate on T-Mobile 3G/4G, or not?
Not talking about HSPA+42, which is still only in some select areas. Talking about standard T-Mo 4G, using the 1700mHz and 2100mHz bands.
Thanks in advance.
The Z doesn't have the required bands for t-mobile LTE, the c6602 model only has the 1700 and 2100 bands for HSPA. However, the c6506 model of the ZL has both the 1700 and 2100 band required for t-mobile's LTE/HSPA.

I just purchased a unlocked xperia z, which was imported from Singapore. From what I read this phone should work on the T-mobile network, but all I'm getting is 2g. I put in the T-mobile APN and even tried scanning but all it shows is 2g. Any insight as to what's happening? Thanks!
The phone has these bands:
Networks
GSM GPRS/EDGE 850, 900, 1800, 1900
UMTS/HSPA+ 850, 900, 2100
LTE Band I, Band III, Band IV, Band VII and Band XX (800, 850, 1800, 2100, 2600)

Galaxy note 3 aws band mod?

The Note 3 from AT&T is not capable of supporting those bands. It is not a world phone and it's transceiver is hardwired for AT&T 850 and 1900 bands. AWS is 1700.
Att s3 and s4 can be mod I don't see y the note 3 can be mod as well. Can some one help.

Here are the only frequencies that the Note 3 supports.
GSM:
850, 900, 1800, 1900 MHz
UMTS:
850, 900, 1900, 2100 MHz
If your carrier or the carrier you want to use the phone on does not support these frequencies then it is impossible to use this phone on those carriers.
There is no mod or fix that can make the phone receive and transmit frequencies that it's transceiver is not setup to do. This is a Note 3 and and not a phone from the S series. There have been significant changes in both function as well as security of hardware and limiting user control.

Not true. The S4 and Note 2 for AT&T were just the T-Mobile versions (AWS-enabled) with AWS disabled. If you used QPST to make a modem NV memory backup from a T-Mobile variant and then flashed that back to an AT&T variant, AWS would be enabled
I should know, I did it to my AT&T S4 which I'm using on T-Mobile and if I punch in a dialer code, I can see it connecting to HSPA+ Band 4 (AWS -1700/2100 MHz).

Will the Z3C work on T-Mobile US?

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.

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.

[Q] Which model best for Australia LTE networks

Hi,
I was wondering which of the two Z3 Compact models would be provide the most coverage with the current LTE and future ones in Australia?
With the Z1 Compact there was 2 models released one for china only without LTE (M51w) and the other for rest of the world D5503.
With the Z3 Compact there is the D5803 which provides the same support as the D5503 but I also see the D5833 listed. This looks to provide more coverage in Australia with band 28 (Telstra and Optus) and 40 (TD LTE 40 - Optus)? For the best coverage should I try and get the D5833? I have only seen the D5803 listed for pre-order. I guess the D5803 would also provide support in the US (and international travel) where-as D5833 wouldn't but would support China.
I know that the Z4 or Z5 compact will replace this in 6 or 12 months but since I tend to replace my phone every 2 to 3 years so I'm trying to future proof myself as much as possible. Thanks.
