Xperia Tablet Z Variants

Hi,
I just wanted to create a place where all the Variants are listed for a better overview:
WLAN (Wi-Fi) only
SGP311 (16GB)
SGP312 (32GB)
GSM/HSPA+/LTE
SGP321 (16GB)
GSM: 850, 900. 1800, 1900
UMTS: 1, 5, 8
LTE: 1, 3, 5, 7, 8, 20
SGP331 ?
SGP341 (16GB)
GSM: 850, 900. 1800, 1900
UMTS: 2, 4, 5
SGP351 (16GB)
GSM: 850, 900. 1800, 1900
UMTS: 2, 4, 5
LTE: 4
SO-03E (32 GB)
GSM: 850, 900. 1800, 1900
UMTS: 1, 5, 6, 19
LTE: 1, 19 ,21
Additional information:
SGP341 and SGP351 are identical in hardware!!
So with a SGP351 FW on the SGP341 you can enable LTE band 4
SO-03E can be debranded with SGP321 Firmware - but the 32GB Memory will be formated as 16GB
Greetings
UserX10
If there is a mistake or you have additional information - please let me know.
Thanks to all users below for providing additional information.

SGP341 is HSPA+ only (no LTE) 16GB.
Bands:
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
I'm looking for a white global LTE model (SGP321), but as far as I can see anywhere, only the 32GB wifi only comes in white (not interested in Docomo branded hardware.
If anyone has any links or reliable purchasing sources with worldwide shipping for this, please post.

Sony Tablet Z
The "SGP351" model number is for an HSPA/LTE variant that appears to be for T-Mobile USA. I am too new to post links but you can find a link to the FCC filing for the device, as well as SGP341, via TmoNews or Wireless Goodness.
Yes, I am keeping a close eye on this one.

Does any of the variants comes with a charger in the box ?
Mine was Docomo version - comes with Headphones & Charging Dock !!

The SO-03E (docomo version) only supports LTE bands 1/19/21
Currently with stock firmware at least anyway, maybe when developers get their hands on a modem files from the SGP321 the other bands might get unlocked, unless its a hardware restriction

Band support is hardware-limited. The only thing you can hope for in some cases is unlocking additional modes in already-supported bands (like Nexus 4 LTE support for 1700 MHz.)
Qualcomm's WTR RF frontends support nearly all bands in existence *but not simultaneously in a single device* - bandswitching and filters are unique to each device.
Take a look at the first diagram at http://www.anandtech.com/show/6541/the-state-of-qualcomms-modems-wtr1605-and-mdm9x25 - the RFFE portion of that diagram differs between each device.

Well I knew that it was likely going to be hardware limited, but staying hopeful that unlocking of additional bands is possible later when more developers get their hands on the TZ.
Being able to use 4G would be a big plus, although I am still perfectly happy with my HSPA+

Wait a minute aint LTE suppose to be backward compatible? I.E should do 3g and HSPA+ ?? I mean I dont have to buy 4G sim just to use with SGP321...

I think you should also clarify which GSM and HSPA+ bands each device supports
SO-03E supports:
GSM: 850, 900. 1800, 1900
UMTS: 1, 5, 6, 19
LTE: 1, 19 ,21
this is from the service menu.

The SIM is the same. The enduser can turn the capability on and off depending which contract he has.
So from this case it is backward compatible.
But seen from the technical side it is not backward compatible, a handover is done between 3G and 4G.
3G/HSPA+ is WCDMA also known as UMTS
LTE is a OFDM modulation
So the technology is completely different

No what I meant was the simslot in the z should accept both 3g and 4g simcards. which you mentioned in the first line.

They may have understandably missed that because the first post confusingly says "WLAN only" instead of "Wi-Fi only". UserX10 should consider correcting that.

I can confirm that my SO-03E (32 GB) DoCoMo branded works in Australia using Telstra 3G but no 4G due to the band differences.

I can confirm that it is possible to flash the SO-03E with an unbranded SGP321 firmware image BUT the LTE working bands remain the same as those that come enabled with the SO-03E: LTE_BC1, LTE_BC19, LTE_BC21. The flashing maintains a locked Boot Loader and hence the bravia 2 engine is retained. I also have an SGP321 which is now running the same firmware as the SO-03E (which is now an SGP321 with 16gig internal flash) but they both have different LTE working bands! The modem/radio software is identical on both tablets but the working bands are different as viewed via the system menu.
Does anyone know where the bands are configured/set as the Qualcomm modem chipset supports all LTE bands..... or is it flashed with the working bands on the chip when produced cannot be reprogrammed/enabled via the Android OS?

Expansys Korea (I cant post the link) has the 16Gb LTE white you want. They have sites for other countries too, but stock varies.
Wish I would of seen this a known the DoCoMo verison I have only supports one of the two LTE bands for my carrier. Signal is weak .... for now.

US 4g Xperia Tablet Z
A T-Mobile USA compatible Xperia Tablet Z (SGP351) is now available directly from the Sony website.

Galaxy S 4 Google Edition GT-I9505G no LTE network (Europe) - any workarounds?

So got my new baby, and I love the stock Android UI.
But I got issue connecting to LTE networks here in Germany. A friend of mine bought it in the US store and sent it over to Germany. 3G no problem, but LTE isn't working.
I checked the tech specs, and it says 4G LTE (700, 850, AWS, 1900 MHz). Here in Germany T-Mobile is using Band 3 (1800 Mhz) and Band 20 (800 Mhz) So there is the culprit.
Is this a hardware restriction, or could be solved via software? Maybe flashing a different baseband?
Unfortunatly on the Phone Info screen, you cannot change the GSM/UMTS band. The list is empty. It worked on my Nexus 4 though...

Maybe its possible with a modified modem/radio, dunno it thats correct though and how to do it. There is a radio thread on this forum http://forum.xda-developers.com/showthread.php?t=2192025, check it there.

It might be possible to change the bands using QPST (you won't be able to flash the international modem) there is already a thread on the I337 forums http://forum.xda-developers.com/showthread.php?t=2291589 that has a tutorial for enable AWS bands on the device. The process should be roughly similar assuming the device's hardware can operate at those frequencies.
If it works you will lose north American bands until you rehash the I9505G configuration back.

If your on Tmobile USA - Buy the Japanese SO-01D Model

In case I am mistaken, currently I own an unlocked ATT model on Tmobile. Recently my area was refarmed to take advantage of the HSPA+ so I get full high speed data on my phone with Tmobile. I was looking at the Japanese Xperia PLAY SO-01D model and it supports all frequencies that US Tmobile uses. So perhaps if you want full support you should look into buying the Japanese Model:
See here for Japanese model Specs, notate the Frequencies:
http://www.umnet.com/phone/6637-Sony_Ericsson_SO01D_Xperia_PLAY
Japanese Model Specs:
Sony Ericsson SO-01D Xperia PLAY Specifications
Networks GSM | UMTS
850 | 900 | 1700 | 1800 | 1900 / 2100
Wireless Data GPRS | EDGE | FOMA
Tmobile USA:
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
Just thought I would share my findings.
Edit: Nothing on Ebay in the US however there is a Amazon.com link to buy them.

I have been watching for a Japanese model for sometime. I figure I have a prototype model and thought it nthrope be cool to have the JPN model as well. It seems to me tis model could be used worldwide. It has more frequencies then other model.
Either way I found it interesting

Please stop. Developer/Prototype is not what the OP meant by "Japanese version." You act like it was never available normally from a Japanese carrier when it was. See the NTT DoCoMo package linked in this thread? Yeah. Also, this was developed by Ericsson, which was not owned by Sony back then and not in Japan.

HDMI had only the model for a fairs. There weren't on sale. Only to use by SE (for example when the showed Minecraft PE).

I bought an R800at ("Sony Ericsson Xperia PLAY 4G") and have been using it on T-Mobile - I do have HSPA+.
Sony Ericsson Xperia PLAY 4G (R800at)
850/900/1800/1900
GSM | GPRS | EDGE | UMTS | HSPA (HSUPA/HSDPA) | 4G HSPA+
According to the Sony specs, there is no difference between the R800a and R800at radio hardware. So really, the only difference may be the kernel's radio that was stock flashed on the device.
I haven't found any solid specs on the SO-01D frequencies - some sites list 1700, some list 2100, some list both. But the old T-Mobile frequencies required both 1700 and 2100 to get 3G. Since T-Mobile started refarming the 1900, it can work with the 1800 to achieve the same results - so as long as you're in a refarmed area you wouldn't really get anything more out of SO-01D than R800a/R800at.
EDIT:
But I'm willing to go get a model SO-01D and do a speed test comparison.

modem hack for Chinese OPO to enable 3G

I thought I might post this in its own thread as it might save people time when they get their Chinese OPOs and notice WCDMA doesn't work..
For all those who don't know, the Chinese OPO does not support WCDMA/FDDLTE in its stock software configuration. You need to swap out the modem to a hacked modem in order to get the feature to work.
I believe the modem attached was pulled from a Find 7, I've tested it, it works. It has been running pretty well for the last week or so but I'll have to test it over the coming weeks to see how reliable it is. They claim 2G/3G but no 4G. 3G/2G works.

can you please explain step by step procedure for same?

so your saying that the chinese and world versions of the opo are the same hardware wise and its just a software modem difference?

I have chinese OPO using on T-Mobile in Hungary. 2G/3G/4G are working out of the box, just for you information.

So for three in the UK the Chinese opo might not work at it's best?
Edit: did some research for myself and it will work fine.

As I saw in one of threads on OPO forums it was explained that chinese version do not support only WCDMA band 4.
According to the wiki (UMTS_frequency_bands) this band is used only by following operators:
North America: USA(T-Mobile US, Cincinnati Bell, i wireless), Canada (Eastlink, Mobilicity, Vidéotron, Wind Mobile)
Latin America: Chile(VTR, Nextel), Colombia(TIGO, Movistar), Uruguay(Ancel), Perú(Movistar, Nextel)

The question is can the modem be flashed to support missing WCDMA band 4?

I just flashed the modem on my Chinese OPO and it works flawlessly with China Unicom's 4G service.

Has anyone tried to flash the CM11S factory image and see if that radio activated the bands? The CM11S factory image includes radio images, and I believe is flashed together as a whole.

Yes. Would like to know if the 1700 and 2100 frequency are activated after flashing the modem.

All-
This is the hacked modem for China OPO that supports China Unicom networks.
I have made cwm zip for easiler install as CM would override the modem during OTA upgrades.
This modem comes from the chinese oneplus forum. See link: http://www.oneplusbbs.com/thread-429139-1-1.html

I have tried other networks with the modem from the ColorOS or CM rom, seems there is no restriction on WCDMA for other networks.

A few things,..
1. I've been lead to believe from various sources that the Intl. and Chinese versions of the OPO are in fact almost identical hardware wise.
see: http://www.gizchina.com/2014/06/12/differences-international-chinese-oneplus-one/
2. I don't have a 4G subscription in China so I cannot confirm whether or not it works with this modem hack.
3. I bought my Chinese OPO from a reseller here in China on Taobao. When I received it I immediately flashed it over to CM11s and subsequently had no 3g (I use WCDMA network China Unicom FYI) for a few days until I found the hacked modem on the Chinese OPO forums. As for those of you who are not in China, I've heard that many Int. resellers will complete this process for you so you won't need to do any flashing yourself, but I can't generalise for all of the sellers out there.
4. I cannot confirm is whether or not this is only some kind of restriction for Chinese wcdma networks (China unicom). I haven't as yet taken my OPO out of this country and tried an international sim card so that is yet to be determined.
ThExSenatoR> I'm curious about your phone configuration perhaps you could post which modem version you use printed from the about screen??
sasalove> are you saying that the Chinese OPO will work outside of China on other wcdma networks but will not work inside China on China Unicom with the stock modems from coloros and CM?
can anybody who uses China unicom on 4g confirm which modem you use and if you also had to flash a different modem in order to access the service?

With some testing, I'm quite confident to conclude the restriction for 3G is on China Unicom only. I got my CMHK and one2free sim to confirm it. I can use 3G and 4G without issue in HK.
I occasionally travel to mainland and I got both China Mobile and China Unicom 3G sim. Only the hacked modem got China Unicom 3G and meanwhile the CM modem cannot connect to the TD-SCDMA for China Mobile.
I'm still waiting for my 4G China Mobile to test TD-LTE...
So in any case, I decide to flash this hacked modem, as it seem to work for all to date...

The modem that come with CM11 should have WCDMA band 4 (1700 MHz) and should also have LTE band 4 (1700 MHz) and band 17 (700b MHz). According to the spec, the difference is supporting TD-SCDMA band 34 (2010-2025 MHz) / TD-LTE for band 39 (1900 MHz) for China. Other than that the spec matches both side.
Therefore, if anyone need band 4 and band 17, they should use the modem that come with CM11 which lack in the Chinese modems.

Thanks mate for clearing that up for me! So it seems that this restriction is only for China Unicom, why might that be I wonder? to my knowledge, It's not like the Chinese OPO's are being sold by China mobile directly...
I'd still like to test out 4G for China Unicom but I would like to find a cheap deal to do it. I can never seem to fully understand the mobile plans in China anybody got any suggestions as to how I might find a plan with a decent amount of data (at least 300mb) for less than 100yuan a month ??

Are we certain that the Chinese OPO has the EXACT SAME hardware as the international OPO sold by One plus?
I remember reading people claiming either side.
Just want to make sure that they indeed have the exact same hardware ie. Radio/modem and just need to have different ROM/modem firmware flashed to enable different bands ie. Band 4 (1700) in my case.

There is a newer hacked modem available. The author states the modem is based on CM12S while supporting all 3G/4G in China. Another user claims to test all of the network modes.

4. I cannot confirm is whether or not this is only some kind of restriction for Chinese wcdma networks (China unicom). I haven't as yet taken my OPO out of this country and tried an international sim card so that is yet to be determined.
ThExSenatoR> I'm curious about your phone configuration perhaps you could post which modem version you use printed from the about screen??
sasalove> are you saying that the Chinese OPO will work outside of China on other wcdma networks but will not work inside China on China Unicom with the stock modems from coloros and CM?
can anybody who uses China unicom on 4g confirm which modem you use and if you also had to flash a different modem in order to access the service?

I can confirm China Unicom 4g is working with the hacked modem.

There is a newer hacked modem available. The author states the modem is based on CM12S while supporting all 3G/4G in China. Another user claims to test all of the network modes.

Cheers mate! On another note, can anyone confirm what their wifi/cellular peformance is like with either the original or hacked modems? Since I've pretty much only used the hacked modem (the one I posted at the start of the thread), I can add that performance wise, it's significantly worse than my computer and old iPhone 5 when using the wifi from my bedroom. Where I sit in my bedroom I get consistent full reception on my computer and used to get the same on my iPhone 5, on my OPO I get 1 or 2 bars at most irrespective of whether or not I use 2.4ghz or 5ghz...
Anyone else experience similar?

i downloaded that before, but i had no idea it was able to change bands i thought it only monitors and tells you what bands your on.

LTE bands depends on your phone hardware
you just can't add any bands
it's hardware dependant i believe

That app doesn't add bands to your device but lets you choose which band do you want to lock among available bands.

Lol, pardon me for misreading the OP
This guide published here should be useful.
It’s not an easy process and there is rooting required, but it will take you through and work for you. You will also need to have your phone rooted before doing it.
All in all, it’s a complex and scary process, and if you’re not used to meddling in your smartphone’s innards, I would recommend staying away from it.
You might end up bricking your phone and losing it altogether.
Also, depending on why you are doing it, some applications of this solution are illegal and might get you in trouble with your carrier.
So just be careful
One more, according to this site, our phone did not even support those frequency which he wanted to work on his phone.
