dualsim 8342 LTE - Sony Xperia XZ1 Questions & Answers
Will the dualsim model also have LTE cat.16 (1gbps) modem suitable for European networks? Or it will only be suitable for Asian networks who mainly use intraband aggregation (4g+)?
Europe and Asia use same methods for carrier aggregation, just a bit different LTE bands are used.
Bands and Carrier aggregation support is same for dual sim and single sim version. Difference comes from that the Single sim version has 4x4MIMO antenna support, while Dual sim version has only 2x2MIMO support.
4x4MIMO antenna is needed to achieve that LTE Cat16 1Gbps speeds.
4x4MIMO antenna support from the telekom side in Europe is actually quite poor, as the population density is low to drive that 4x Antenna adoption.
4x4MIMO usage in Asian telecoms networks is actually quite high, due to higher population density.
So in summary, i would recommend definitely to get the Single sim version of XZ1 if you life in Asia as you would get much better LTE speeds out of it.
While the Single sim version would be preferred device for Europe also, you would be still okay to keep using Dual sim version for couple of years.

Let me know if your country is missing(check country code from Lists sheet).
Network code is 202-01.
I m between to choose xz1 or xzp (single versions both), I definately need 4x4mimo, my carrier will launch it within few months.
Ca combinations for both devices are almost identical for my network but in total +102 combinations more for xz1.
Will xzp offer same ca combinations in the future (maybe with baseband update)? Or 3gpp release version of each device is one-off?
Xzp dual is also 2x2mimo?
I don't think that XZ Premium will get any more bands support or extra CA combinations that are in XZ1 via baseband update. The new bands and CA in XZ1 are more useful in North American and Asian markets anyway.
You will be in a good situation in Greece Cosmote network with both phones. VoLTE/VoWIFI support for both and decent CA support when in home and traveling abroad.
Personally i would go with XZ1 as it fits in hand much better than XZ Premium. I have "old" XZ and XZ Premium myself, XZ is still the main phone for me.
At the moment single xzp is sold cheaper than xz1.
Also I have a doubt about xz1 battery because I mainly use cellular data network rather than WiFi.
Can my network in the future be upgraded in Sony's ca combination list? Offer more ca combinations/change category? For e.g. they say (network) they may support 7+7+3 60mhz in the near future.
Has xz1 activated 256-Qam for EU region? xzp has.
*I'm a fanatic cellmapper user.
XZ1 and XZ Premium batteries will balance out i think. XZ Premium has bigger battery, but much bigger screen to feed.
The spectrum in Greece for B7,B3,B20 is already pretty well divided, all B7 and B3 and B20 is allocated to providers.
I have made small comparison table just for you. Cosmote Greece and XZ1 vs XZp https://docs.google.com/spreadsheets/d/1g5KRgOimFopK3dpBd-ajJs6QyA5LH8WDrlqrDSEgqeY/edit?usp=sharing
If operators want more CA combination support in Sony phones, then they need request/pay Sony to do that. Depends if operator plans to use those CA combinations in their network.
XZ1 and XZP both have exact same operator specific configuration file. If you say that XZp has 256QAM then i am pretty sure XZ1 will have that also.
Looking at the hardware capability of both phones and current LTE spectrum holdings of Cosmote Greece, i would see following currently missing CA combinations possible in their network.
38A-7A-3AA-0 (60Mhz total)
38A-20A-3AA-0
38A-20AA-7A-0 (XZ1 only)
38A-20AA-0
B38 20mhz is bought but not used as of today.
Also cosmote has bought a second 10mhz b7 spectrum, but is also not used as of today. Today 10mhz b20, 20mhz b3 and 20mhz b7 is used for 500mbps max using 256qam.When 4x4mimo is launched will possibly upgrade to 900mbps max. using 4x4 on b3 and b7.
Has any network worldwide done 4x4 mimo on b20 (800mhz)?
*this year cosmote is allocating some b8 900mhz from gsm to umts.
4x4 MIMO on 800Mhz(or any other low band) is not possibly on device side, due to physical limitations.
You are welcome to discuss networks and cellmapper in the Telegram chat https://t.me/cellmapper
4x4mimo on b1 2100mhz is supported on xzp and xz1?
My network may allocated it in the far future from umts to LTE.
38A-20AA-7A-0 is supported by xz1 but not from xzp?
Personally i have confirmed 4x4MIMO on "old" XZ B3 B7 B38 - no B1. XZ Premium has been indirectly confirmed to have 4x4MIMO support on B1,B3,B7(no info on B38 or others). I am confident that XZ1 willl match 4x4MIMO support on those bands and probably add support for US bands as well.
Is it sure that dual xz1 g8342 is only 2x2mimo?
Why new ca combinations (for eg those supported from xz1) cant be added to xpz? Its still a flagship.
I am not 100% sure that G8342 is not 4x4MIMO and only 2x2MIMO, but the 2nd sim capability is not "free" and has to come from expense of some cellular(antenna) capability.
Thats why dual sim op3(x12 modem) was only 2CA, Op5(x16 modem) is only 3CA. Also all the Gigabit LTE demos are done using single sim XZp.
Based on these previous information, i have no confidence to recommend dual sim version as 4x4MIMO device.
Anyway you get much better firmware support for single sim version.
It's possible that XZ Premium may get additional CA combinations support, but as it probably requires some kind of certification(money) then i would not hold my breath for that to happen.
No guarantees.
Ok but g8342 dual is advertised as cat.16 only in one sim, so i suppose its 4x4mimo capable. But we need to clarify this.
Has Sony done it before in another device? (To add some ca combinations at a later time).
Kirin 970 soc with 4x4mimo on 3carriers (cat.18) is already out.
Sony added CA combinations using B32(first available to XZs) to XZ, but the band support itself was already there. So a pretty minor addition.
We need root with DRM fix on XZ Premium / XZ1 / XZ1 Compact then we can confirm 4x4MIMO/256QAM support with app Network Signal Guru.
Come and discuss Kirin soc and other stuff in Telegram chat https://t.me/cellmapper Easier than posting here
Sony just started supporting dual versions of both xpz and xz1 for the 1st European country, France.
Thailand 3CA support
Does this line means Thailand will have 40-40-40 support? Does it also mean it will have 256QAM/4X4 MIMO when doing 3CA on band 40 as well?
40C-3AA-0
I will be very interested if it can also do 1-3-8 + 256QAM/4X4 MIMO.

XZ1 Dual G8342 and XZ1 (G8341) both have most CA combinations(136 variations) available in Thailand compared to any country.
Thailand has support for 40C-1 and 40C-1, which are contigious B40 (20+20Mhz). 40D would be the 20+20+20 possibility which it does not have enabled.
It does have support for 40C-3AA and 40C-28AA, both 3CA when B3 and B28 are primary band(second A denotes the primary band).
You can check CA definitions here http://niviuk.free.fr/lte_ca_band.php
While the single sim and dual sim model share exact same CA combinations capability, there are some differences between the 2 devices.
XZ1 Dual G8342 has Customized TH firmware available, meaning that you get 256QAM and VoLTE etc stuff for dtac,ais and truemove. 4x4 MIMO support unconfirmed.
XZ1 (G8341) has no Customized TH firmware, meaning that you will not get any VoLTE(ordinary 3g calling instead), no 256QAM. But 4x4 MIMO is known to be available.
4x4 MIMO on XZ1 (G8341) is supported on bands B1,B3,B7,B38 (North American B2,B4,B66 yet to confirm).
XZ1 Dual G8342 will get you 1-3-8 + 256QAM, but 4x4MIMO on bands B1 and B3 is unknown because have not seen anyone confirm 4x4MIMO on dualsim version yet.
Thanks!!
I'm looking for phones with 40-40-40. However, there doesn't seem to be any of them around.

What is Le Max 2's LTE A category?
Anandtech mentions it is LTE-A Category 12 (600 Mbps) Some sites mention it is Category 6 (300 Mbps) So what is it exactly?
With the new Non-HLOS.bin shipped with 17 S, there ist no cat 6 LTE , only 150 Mbit cat 4. The + sign at 4G sign doesnt appear
So should I go back to Indian 16S ? I am aware Indian 17S or 18S is on the verge of getting officially released. I prefer the Chinese 17S because battery is absolutely brilliant after removing the bloat. Indian 16S has horrible battery and standby time.
How to check the LTE-A ? I'm on CN 16s, in Malaysia (CA Band_3_7). Whenever my phone show 4G+, then phone signal will drop for total no signal, can't call or data (Searching mode)

Snapdragon 820 has X12 modem (category 12 LTE up to 600 Mbps). I have had 4G+ for ages (in Japan on OCN Mobile One, an MNVO on the docomo network). However, as it is an oversubscribed MNVO my speeds are never great and even when getting a CA (4G+) signal they don't really change. My current firmware baseband version is as per this screenshot:

Click to collapse Unfortunately even on the same base chipset some of the radio params are up to the OEM, depending on what band combinations LE have programmed CA may work with some networks and not with others (eg OCN might be using 20Mhz x2 in 800Mhz while ThreeUK might be using 1x 15Mhz on 1800Mhz and 1x 15Mhz in 800Mhz).

Not all bands are turned on for our device so some people some places are going to be SOL. In the case of OCN the carrier aggregation is probably working with bands 1 & 3 I guess (the other bands OCN use are 19 & 21, which are not available on the LeMax 2).

His Z Play has the same available OCN LTE bands as my LeMax 2 (B1 & B3) and Motorola say it is CA compatible, but while I get 4G+, he doesn't. And another friend has a Japanese version ASUS Zenfone 3 and he gets 4G+ on another MNVO using same docomo network with B1 & B3. So it seems to be a bit of a lottery depending on your device & your region & carrier.

Click to collapse Compatibility isnt straightforward as its also dependent on resource blocks or RBs. Some radios can handle CA 2x 2x20Mhz and some might only manage 2x 2x10Mhz. Thats why reading the RRC messages between tower and handset is useful as OEMs dont release the full config that their UEs broadcast.
Snapdragon 820 aggregates 3 frequencies (3CC). I never managed to force him to do it, but 2 can (2ca).
Does the Sony Xperia XZ1 get VoLTE on T-Mobile??
If you're answering this thread, you should have 1) The Sony Xperia XZ1 (please mention also if it's the int'l model or U.S. one) 2) T-Mobile as your network carrier. Some online publications state the XZ1 will be VoLTE-certified with T-Mobile, while others don't. T-Mobile REQUIRES VoLTE-certification in order utilize the newer Band 12 on their network, so this is pretty important as this band is becoming more and more prominent. It has a much farther range than their other bands (2 & 4), and also is 4 times better at penetrating buildings. Thanks!

To see them, use Network Signal Guru: https://play.google.com/store/apps/details?id=com.qtrun.QuickTest Root required, you don't need to pay for Ultimate Service but the app for free is of no use with dual SIM - disable SIM 1 or SIM 2 Screenshots below show three Aggregated Carriers: the so-called combo 20A2-3A2A-1A2 (Primary b3, Secondary b1 and b20), aggregating non-contiguous intra-band 20+20+15 MHz , on Mi 9T, stock QFJEUXM 11.0.5 (no QPST modding needed to get it working) I have used SIM 2, and it was with the provider who supports exactly those three 4g bands: b1, b3 and b20. For the test I disabled WiFi and SIM 1 (provider supporting only b3 and b20 - will test later), and for download started to play an HD movie by YouTube Vanced (to be able to push it to the background) I don't know how would Aggregated Carriers work with CN or IN firmwares if used e.g., also here in Europe. Also, if and how custom ROMs support LTE+ Aggregated Carriers - but one could test himself Of course, it also depends on your 4g provider, potentially your Mobile Internet subscription and the available 4g bands at the given time and location
Another example with my SIM 1, different Mobile provider, providing only two 4g bands, b3 and b20 Here I got CA combo 20A2A-3A2-3A2 (Primary cell on b20, two Secondary cells on b3), aggregating non-contiguous intra-band 15+20+10 MHz
S10 Lite & SIM Band frequencies in Japan
Hello, I have a fairly difficult technicaly question regarding the Samsung S10 Lite. I recently purchased the S10 Lite (SM-G770U1 )and I am currently residing in Japan. To my surprise, I have learned that almost all carriers do not support the model that I have (listed above). I have managed to find one carrier that I think might support the phone, but I am unsure whether the Frequency bands of my model are the ones listed by the carrier. The bands that are supported in Japan are the 3G Band 1 (2100MHz) or 4G Band 1 (2100MHz) frequency. Please let me know if these are supported by SM-G770U1 Model. Thank you so much in advance! Name of the Japanese Carrier with the SIM information (thought it is very limited) https://www.mobal.com/japan-sim-card/
Question European S23U in US
Now when European S23 Ultra is using Snapdragon - will it provide better 5G connection capabilities in US - especially on TMobile network? Or is it still locked to the same (limited) bands as Exynos S22? thanks
It's SM-S918B or SM-S918B/DS right? It would partially get 5G specifically for TMo where areas have n41 (2500) Only the SM-S918U or U1 has the mmWave antennas These are what T-Mobile uses for 5G n260 mmWave (39GHz) n258 (24 GHz) n261 mmWave (28GHz) n71 (600) n41 (2500)
SM-S918B/DS. Ok - so it looks like it will not be better in US than S22 Ultra Exynos.
