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.
You can check out which lte carrier aggregation combinations XZ1 G8341 supports here https://docs.google.com/spreadsheets/d/1Itt7bKftWTQtKHs76-pRT5H1KEBYSoI1kdqeGjJpWMU/edit#gid=0
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.

I Purchased the note 20 Ultra 5G in USA and shipped it to Australia.
I later found out that the US Note 20 Ultra 5G variant doesnt have band n78, which is the main band of Asutralias best 5g provider, Telstra.
I am wondering if anyone knows conclusively if the s7 5g or s7+ 5g has the n78 band, some websites denote it does, others say it doesnt, but i feel they might be reffing to the LTE version sometime which of course does not have n78 5G band. This is the US variant from Samsung.com website.
Thanks in advance
Hello,
I am looking to buy an unlocked S21 from Samsung Canada store (SM-G991W) and I checked here :
S21 differences that the following 5G bands: n2, n41, n66, n71 are the ones supported by the Candian model so my question is:
Is it possible to change the supported bands? For example, if I travel to a country where the used 5G band is the n28, will the S21 support this band. If so, how please?
Btw, I have seen some users changing Network bands on Samsung devices without root so I want to make sure that it works with the 5G bands especially from someone who have a S21 please?
Here is the link of the short tutorial: Un/Locking LTE Bands on Samsung I am talking about.
Thanks for your help

The SM-G911W had the following technical specifications for mobile network 5G: 2, 5, 25, 41, 66, 71, 260, 261.
Check here for differences of the S21 5G variants:
Samsung Galaxy S21 5G Model Number SM-G991* Differences - TechWalls
There are a lot of model numbers of the Samsung Galaxy S21 5G on the market but all of them start with SM-G991. To find out all the differences, you can check the comparison table below.
www.techwalls.com
AFAIK this is caused by hardware. So no software related "unlocking".
Does the dual sim s21 sm-g991b get 5g on tmo usa? The icon shows lte+. Is that similar?

Hi mate
the phone is capable but your carrier maybe not lte+ is not 5G
Check here
You'll get the N41 5G band, but you wont get N71, N260 or N261 (the 2 MMwave bands). You're also missing some important LTE bands on it too.
You won't have a good time with that device.
And no, LTE+ is 4G. 5G is 5G.
