Anyone else have issues with Carrier Aggregation not working on the Z5C?
My Nexus 5X will bond Band 4 and Band 12 LTE and I'll see ~25 Mbps speeds at home.
On my Z5C, it will connect to Band 12, but appears to not be aggregating with Band 4 and I only see speeds of ~4 Mbps.
This is in the same location, same SIM card, etc.
I only get band 2 here, so I can't say for much but have you tried other firmwares?
E5803 has no CA support; only E5823 has it.

If it's a real E5823 HW, there would be no problem for CA.
The only difference between E5823 and E5803 is the main board, one with CA; one without.
The antenna design is the same and simple, so there should be no performance issue.
There is one tiny possibility: your HW is E5803 with E5823 SW. Just a wild guess.
MiscTA 2555 contains the HW RF config.
E5823's MiscTA 2555 is much longer than E5803's.
You live in the USA? As far as I know, only E5803 is in US market.
So maybe E5823 CA is not compatible with US operator under US RF rules.
But once again the E5823 HW has CA support.
All the information for your reference.
ps:
You probably should complain to your operator.
In Beijing, China, under CMCC TDD-LTE no CA I can get 33Mbps with a local provider's HW.
Good day.

I bought E5823 from UK, it says that on the paper as well inside the unit. Not sure why it is not working.
I am going to correct my first post saying I only get band 2, I've been watching which one I'm on while traveling to and from work and I cycle through all three 2, 4, and 12. Is there any app that shows if I'm on multiple? I was using LTE discovey

It seems the Z5c lacks 1700MHz band 4, which should mean Telus and Bell (same for T-Mobile?) are **** out of luck for LTE. Can anyone with the device or more knowledge confirm?
That's strange that they dropped it, though according to this, it shouldn't be a big deal either:
http://www.xperiablog.net/2015/10/07/usa-buyers-guide-sony-xperia-z5/
Just got my Z5c, and did a Speedtest.net
The results are 28Mbps/11Mbps, which is as good as I got using LTE on my Nexus 5, though my antenna bar reads "4g" not "LTE".
So I don't know what to tell you!
No, no AWS, but speed as good as AWS anyway.

Indeed, however all promo screenshots of the Z5 show "LTE".
Here's an /r/android post I just did with some more info:
Disclaimer: I'm not educated in the technical aspects of mobile radios, and the following info rests on the shoulders of forum reading and a small amount of real world testing.
This should be the same across all Z5 phones - Compact, Regular, and Premium.
Telus, Bell, and to some degree T-Mobile and AT&T use band 4 LTE. Telus/Bell specifically use 1700/2100 AWS for LTE. I got my E5823 this afternoon (black Z5 Compact), and I've been fawning over it all evening. Here's what I've found on my Telus network:
I'm reliably getting ~30Mbps down, and ~12Mbps up.
My Z3c reliably gets ~30Mbps down, and ~28Mbps up.
Which makes sense, as I'd seen a couple forum posts saying that 2100MHz is for AWS down, and 1700 is for AWS up, and the Z3c supports both while the Z5c only supports 2100MHz.
For me, this is good news, as I was afraid I'd be on 3g all the time, and not having full upload speeds don't bother me, as 99% of my uploading is on wifi.
In other news, this phone is AMAZING. Happy to answer any other questions re: data or the new phone.

Thank you for the info. I recently discovered another variant "e5803" instead of the model mentioned here and elsewhere e5283. It seems to list the same radio frequencies but could this just be a naming variation or will this be the US model similar to z3c d5803?
Lastly, if we are purchasing a supposed "international" model, will Sony USA provide us warranty or would be from the seller?
Really interested in your input before I fork over $$$ on this cool phone.

Hey guys.
I just made this account because I have a major phone crisis. I was thinking of buying a C5 Ultra to replace my broken phone.
But I'm not sure if the 3G and 4G LTE will work with it? I'm not particularly tech saavy. I asked five different representatives from my phone company and they said yes. I've also talked to two Sony reps and they weren't very helpful.
But I'm still unsure. My phone carrier is Claro (Puerto Rico). This is the info they've provided me with:
3G Operable: 850MHZ, 1900MHZ
4G Operable: 850MHZ-1900MHZ, B4 AWS (1700-2100), B17 (700MHZ), B12 (700MHZ)
Which left me still slightly confused. My band knowledge is basically squat. And I've been pulling my hair trying to make heads or tails of the different statements the reps have told me. They all say it'll work and yet I don't want to spend money on the equipment only to find out it doesn't work.
Anyways if anyone could help me out with this I'd be super grateful.
According to this Wikipedia list (https://en.wikipedia.org/wiki/List_of_LTE_networks) your operator seems to be using LTE Band 17.
And according to Xperia C5 Ultra specification white paper from Sony website (http://www-support-downloads.sonymobile.com/e5553/whitepaper_EN_e5553_e5506_xperia_c5_ultra.pdf) the only model that supports LTE Band 17 is the E5506 (Single SIM, none of the Dual SIM variants support the LTE Band 17).
When I bought mine the model number was printed on a sticker on the bottom of the box.
Also, I would suggest you double check with your operator whether they’re actually using LTE Band 17.

They use Band 4, 12 and 17. I've actually asked them extensively about it. My only option would be the E5506, but I've no idea where to buy that -specific- model. I've been searching for almost a month. Sending e-mails and posting on forums, ect. No dice.
Looking at the Wikipedia list it seems that Band 4, 12, and 17 are mostly used in the countries around Northern America.
Based on past releases, Sony has always prioritize the Asian and Europe market first. Northern America model is almost always released last. I guess you'll have to wait.
Of course this is just a guess, I could be wrong.

Just wanted to update this thread with new info. I'm now in possession of a C5 ultra E5506. I saw it come up on B&H photo and video and immediately bought it. It seems to work with 4G and 3G just fine.
So yes, its out there now. It just took a while.
I will order the z5c soon and have accounts with both Tmobile and AT&T. Should I hook it up on AT&T because of missing Tmobile bands? Are there any missing at&t bands? Buying the UK version from either Handtec or Clove. Please advise if anyone knows. Thanks

The E5823 model supports all of T-Mobile USA's LTE bands 2, 4, and 12. Band 12 (Extended Range 700Mhz) is questionable though. That particular band doesn't seem to be fully supported yet as Sony would need to get the phone validated on T-Mobile's network. Given that there's no USA model, it's unclear if this will ever happen.
That said, using the LTE Discovery app, I have seen my Z5c jump onto Band 12 if low coverage areas. When I had 4G enabled, band 12 didn't seem to work. When I was in HSPA+ mode, band 12 seemed to work.

That's no good. I was thinking of getting this to test band 12 on tmobile. I currently use att, verizon, and testing tmobile. I already have z3c on att and thought I'd try the z5c for band 12 and put on att when/if i drop tmobile.
That really only leaves m9 or iPhone 6s for my options as i don't really want a gs6
Edit: I also noticed that it does not support bands 29/30. I believe att will soon be using b30. Probably not a big deal for a while.
This phone also does not appear to support WiFi calling for tmobile USA if that's important to you.
So the E5823 model supports all tmobile LTE bands besides 12 right? just double checking, I don't mind band 12 since it's not in my area yet
Not sure where the lack of band 12 misinformation is coming from but I am in a Band 12 area right now and my z5c works great with it - confirmed on LTE discovery Android app.
Band 12 works fine. Sadly the 3 most important innovations, wifi calling, VoLTE and HD voice, do not and it is not likely they ever will

This is what makes me sad. VoLTE support for areas where T-Mobile has only B12 would be great for when I travel into those areas, like northern Michigan (Chicago area native here). The Z5C would be great for most places I go, but I know I wouldn't get VoLTE calling in some areas.

What market are you in? I'm most concerned/interested in what the Z5 and Z5C does if you're in a B12 only coverage for T-Mobile and you try to make a call. Does the phone roam then to another carrier or just not make a call?
Hmmm not sure. I'm in South FLA. I just see that I'm on Band 12 regularly

I was at walt disney world two weeks ago and picked up band 12 at the art of animation resort lobby and speedtest was logging 65 mbps. Unfortunately that was the only place I was grabbing band 12. No service in any of our rooms and the park in general sucks if you are a tmobile or sprint customer. One or two bars of band 4 lte outdoors if I was lucky. But for whatever reason the hotel lobby had great band 12 reception. I have been generally displeased with tmobile coverage. Their marketing ads do not match up to my lackluster experience both with this phone or my (supported) Nexus 6. Ive been thinking of switching to ATT. Everywhere we go my wifes ATT iphone has LTE coverage while im lucky to make calls. Lol

I had the exact same experience this summer - got so jealous of my wife having signal that I joined AT&T. I was happy for about 3 months, getting signal everywhere before I realized that the data speeds are pretty mediocre. Plus, their prices for capped data are ridiculous! It cost me an additional $45 when I went over my cap by 3 gigs. I'm tempted to switch back now, but T-mobile jacked up their pricing for unlimited data since I left. 2 lines with Unlimited Data used to be $100. Now it's $140. Not sure if I can justify that price increase, though it's still a better deal than AT&T's limited data plans. I live in a major city, so AT&T and T-Mobile both have excellent coverage here. I spend 98% of my time here, so I should be satisfied if I can't get a signal the other 2% of the time, right?

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)

If you get a chance please post your modem version. Thanks.
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:

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).

Yes, obviously availability of CA depends on carriers and on the LTE bands available to the device. 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).

CA is strange. My friend has a Moto Z Play he bought direct from Motorola Japan. He is using OCN, same as me. 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.

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).
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.

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).

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.
