Hi,
For 4G+ Intra or inter-bands ? Someone have an answer for this question ?
Some devices, like Honor 7, are given for having 4G+. BUT only with intra-band system.
And in some countries, like France, 4G+ impossible with an intra-band system, only with inter-bands.
Therefore, you buy a supposed 4G+ device, and you always stay on 4G .
That's why an accurate answer about this question is important.
Thank you very much!
However there are also some LTE band differences between the 3 versions:
- Global 4/64 dual SIM
- Global 3/32 dual SIM
- Global 3/32 single SIM
and maybe Chinese versions are even different.

A similar problem about 4G and 4G+ in France was discussed on XDA about the Huawei Mate 8.
Thank you.
I was talking in fact for the EVA-L09 sold in France and Europe. Single sim 32Go.
And yes, I was also thinking about the similar problem on Mate 8. It's true.
It should be better if Huawei communicates more accuratly about this.
About the Mate 8, I can say that my Mate 8 (international European L29 version unbranded) never showed "4G+" in Italy (I even doubt the 4G+ symbol is included in its ROM...), whilst my new Samsung S7 Edge always shows 4G+ in the same locations...
Exact. That's why I'm in doubt about Huawei devices now...
Up
Someone got working 4G+ with european version?
I would be intrested too.
EDIT: Never seen 4g+ symbol...
As i didnt know about this problem and one of the main reasons i bought this phone was 4g+. So finding this out kinda angers me. I already contacted huawei regarding this lets see what they have to say about it.
I get 4G+ on my P9 when an EE SIM is on it (UK), so that will be 1800+2600 LTE.
First Huawei/Honor device that I've had that shows the + bit (P8, Honor 5X, Honor 7, Nexus 6P all don't).

I have vodafone ITA and 4g+ should also be 1800+2600, but i have never seen the + icon. I have a eva-l19, what model do you have?
EVA-L09

As my p9 is the eva-l19, which has less bands for LTE, i will still wait for huawei's answer. I have a feeling my p9 doesnt have proper carrier aggregation...

Yeah, Huawei answered me on social media, and they just told me what 4G frequencies the phone has. Support still hasn't answered me, which i guess means they won't answer.
I haven't seen the 4G+ icon once...

but by all logic it has to work if the frequencies match right ? since my carrier uses most of the l19's frequencies yet nothing, but I still somehow hope that it is just a software glitch, because as I mentioned before, that I believe, that I saw 4g+ icon when I unboxed the phone, but when I updated it , it was gone, although I'm not complaining about the speeds since my top speedtest was 75mbps down and variating 25-75mbps, while up 7-22
So Huawei actually answered, they say that they do not have access to this information, which feels strange. They sent me a lot of data regarding the bands, like frequencies, signal strength, downlink and uplink on different bands, but no carrier aggregation bands....
Hello,
P9 lite (VNS-L31) B130 firmware. No 4G+ icon

Hello there!
Long time lurker of XDA here - I'd love to enlist the expertise of all you guys here
Was terribly impressed when you guys figured out how to unlock bands and thought you guys might be able to help me (or rather everyone in my country using the A3010) out!
So in Singapore, our carriers use bands 3/7/8 (1800/2600/900 mhz). Unfortunately for us, Oneplus does not ship directly to Singapore so we often have to rely on third party parallel importers, and most of their stock is the A3010 one.
So the bands supported by the A3003 and A3010 models are below.

}
As we found on our local forums, the A3003 is somehow able to get carrier aggregation but not the A3010 and we're all quite puzzled as to why.
One of the theories is that the CA bands (which are not listed on the Oneplus website) are different between the two models.
Perhaps someone here might be able to help?
all singapore bands are supported by China Model,
you need to know what bands exactly are used by your carrier for CA,
and by saying CA is not working, what kind of method did u use to check it ? since not every ROM can show the difference between using CA or not,
yes, 4G+ is a clear indication that your phone use CA, but again, that's not always a case on every ROM
i would suggest u to run network signal guru while doing speedtest, and see whether your phone utilize the CA or not
in a normal situation, the phone usually wont use CA. It will only use it once there's significant data traffic,
example, the phone might not use CA just for pulling GCM push, but will use it on streaming session,
at least thats what happen in most of phones i used,
my A3000 can use CA with no problem, so does the Mi5, S7 edge, and even the economic Redmi Note 3 can do CA
also, each carrier might use different config for CA,
example, my carrier only use CA on band 40, and wont do so on band 5,
you can see my screenshots bellow, my area do not have strong band 40 signal, thus the phone wont be able to use CA, since it only connected to band 5,
but by locking my band to 40 ONLY, and forcing the phone to use it, the CA is easily triggered

Thanks for your input! As what I understand, everyone who commented were using OOS 3.5.4/3.5.3 so with regards to the ROM I think that was standardized..
For the benefit of everyone going to do the testing, which segment of network signal guru demonstrates the use of CA? The terminology on the app is slightly complex too

The first page will show you LTE details, next page (swipe left) will show you LTE CA Matrix, if your phone use CA it will show that it connect to at least 2 carrier(s)

Root the phone, Download Network Signal Guru, Open it, look at the top right, there's three dots menu button, tap it, and choose band locking,
disable all unnecessary or unwanted bands
Hope someone with the right knowledge can come around to advise how to make A3010 get 4G+....
Is your problem solved? I'm also having problem with mi5. No CA on band 3+7. Unfortunately Malaysian telco also using band 3 and 7 for CA.
Same problem here on A3010 Maxis Malaysia where it needs B3+B7 to do CA.
A fellow friend has opened a thread, OnePlus bughunters requested for logs but keep on saying issue was not seen through the logs.
https://forums.oneplus.net/threads/4g-missing-in-a3010.495892/
Would be great if anyone can advise how to do CA on B3 + B7 in a way of unlocking if it is possible just like how unlocking other bands was performed

Can anyone confirm the compatibility of the Exynos variant with T-mobile? Frequency check websites show 100% compatibility but looking for personal experience feedback. Also curious if B66 works as intended in the US.

I just noticed that the service is like just a little worse, you most likely wont notice a difference.
Anyone play around with the idea of loading the T-mobile S8 firmware onto the Exynos international version of the phone to see if that would be enough to get Wifi calling working? Wifi calling is essential to me since I work in a building with great wifi but no service.

You cannot install Snapdragon firmware on an Exynos based phone. This will lead to a brick. The only thing from a Snapdragon firmware you can install I believe is CSC but don't quote me on that.

I was also wondering if flashing the tmobile CSC to the 955F would enable wifi calling. The only LTE band that the Exynos variant doesn't have that T-mobile uses is 66 and from what I've been able to research that's not sued int he NYC area. But wifi calling is critical. I use it a lot to call back home when I travel abroad.

That is incorrect. The 950F does support band 66. I took this from service mode on my 950F

I can't imagine 955F would be different from 950F
I received my phone yesterday. After a couple sites reporting it did support band 66, I dove in and was not disappointed.

Thanks but there's something weird about your screenshot. Band 32 is out of order and is not used on any Samsung phone. I think that should be 42. I find it hard to believe that there is a typo in the service menu.
I was using frequencycheck.com and willmydevicework.com as my sources. I agree that on this point I'm positive that the 950 and 955 should be the same.

Yeah it's strange and I do think it's a typo. But that's what service mode shows, regardless of which SIM I select.
With the exynos you'll also lose VoLTE. Meaning in areas where T-Mobile is using B12 LTE to extend the range of its network (B12 LTE 700mhz goes further than their EDGE and HSPA network (1700,1900,2100mhz) so if you're in an area and only have B12 LTE signal you won't be able to make or receive calls or texts. And in an emergency scenario if there was no other network for your phone to roam to, you also wouldn't be able to dial 911. Kinda an important feature imo.
I use the 930F on t-mobile and will likely do the same with the s8. If you care about rooting, you should get a 950f. It can be rooted easily and with root, you can get TKKG1994's CSC selection tool and use it to enable VOLTE/Wifi calling). If you aren't going to root, then the carrier phone is good.
I don't know how gigabit LTE is affected but I doubt in 2017 this is a game changer.
I bought an S10 5G korean version 977N KT branded, my carrier is Vodafone Italy and everything works fine, apart the 5G connection, never seen on the display. Does anybody have the same issue using the korean device abroad?
Korean S10 5G only enables 5GNR Band 78 when certain operator (ie: Korean) SIM cards are inserted. Otherwise inside the UeCapabilityInformation it sends, it only includes LTE Bands (1, 3, 7, 8, 20, 32, 39, 40).

Could a proper firmware or a custom rom solve the problem?
I think it's something in either the CSC or the baseband, but not sure.

Will the new update to Android 10 help overcome this constraint?

Yes right, I do have this model. but do you expect 5G is optional for this device manufactured to support the 5G network!, logically no!!
It is an essential feature that should be available as the other features!
This makes me think that the model is not fully supporting worldwide 5G networks bands and it might be equipped with a certain 5g-modem that supports KT 5g-NR bands ONLY!! . in addition, the low price for the N model also supports this assumption!
---------- Post added at 01:35 PM ---------- Previous post was at 01:30 PM ----------
BTW Mr. Waterskier, How much the difference in price for the two models since you had got both of them?
Got my 512GB on 27th. Came from S10+.
My Quick reviews after 5days :
The silicon cover is soo bulky with spen.
Battery life is great. Last me a day with light gaming.
All night mode pic are sharp.
100X Zoom looks good compare with my Canon 5DM3 400MM with digital crop.
CAmera AI is kinda AI
Samsung UI not laggy like any previous version of Galaxies.
Phone is kinda heavy.
The system partition uses less space compare to S10+ 512GB.
Speakers are loud.
Audio paired with Sennheiser Momentum 2 sounds great.
Samsung DeX is smoother compare with S10+.
8K video is acceptable.
Fingerprint unlock is fast. Accuracy 1/50 failed unlock.
Thats it for now folks.

I hope it gets updates faster than. The note 20.ultra equivalent (sti on Android 10)

Shouldn't it be SM-G9980 DS? Not SM-G9880 DS.

Using mine in Switzerland, works just fine, haven't tested 5g yet, there isn't where I live
my experience with night photo - very noisy, iphone 11 pro max beaten it in every aspect,
auto switching between cameras is funny - You increase zoom, as soon as it gets to the next lens the quality degrades then as You cross "logical border" the quality returns back to normal (or expected one), so the steps are very discrete comparing to smooth switch on iOS

I have this device running WIFI calling on a Tracfone MVNO over T-mobile's network in Sim2 - I've not been able to get wifi calling to work with Xfinity Wireless in sim1 but that's because they know my phone isn't the device that I'm supposed to have on my account and they can't (or won't) update because they think it's not supported on their network... Have you reset the network settings recently? Entered the band selector and made sure you've got the proper situation going for your scenario? *#*#4636#*#* I'm working in the NV memory fixing the config files to enable the US 5g bands at the moment. Haven't notice any issues with the latest update.
Without ignoring the top line specs this device is not much of a value. It's selling well mainly due to Samsung's huge trade-in offers but for half It's price one can aquire Samsung's A72 with a Snapdragon SoC, Dual SIM's, 8GB RAM, 256GB Internal and up to 1TB External Memory, 6.7 Inch Display, 3.5 mm Jack, 5000 mAh Battery and 120Hz Refresh Rate for under $470 USD.

I found a fix on TMobile. I went and got a new sim card. That was it. Wifir calling and VoIP now.working again.
Has anyone else got a CN version and on Vodafone UK? I can't seem to get 4G+ or 5G to work. Download speeds on 4g are a lot less than my S21 and Cellmapper seems to confirm no LTE-A or NR. Even tried a SIM swap but that doesn't seem to have helped.
It's fine with my EE SIM, shows 4g+
Some googling shows others with similar issues with no CA on some European networks but others are fine. Wondering if the EEA firmware is likely to have a different modem config file?
I have a CN model and my EE gets 4G+ and 5G without any issues.
I also have a work phone on Vodafone. If I take the Vodafone SIM and put it inside my Mi 11 Ultra, it only shows as 4G. 5G won't turn on either even though it's supported in my price plan and works on my work phone.
One thing I have noticed is that the CN model does not support Band 32/1400MHz SDL, which Vodafone in the UK uses whereas EE does not - could this be the main difference as your area happens to rely on this band?
I don't think that's the issue. My local area masts only have band 1,7 and 20 anyway on Vodafone UK and on my S21 Ultra I get CA ok.

Strange, not sure what it could be. Likely some sort of firmware issue/config matter then as I can't get LTE on my Vodafone work SIM either.
Hopefully once it's out in the UK I can replace the firmware with that version. I will try the global one next week though.
The xiaomi.eu roms are based on the CN version, so likely to have the same modem files I assume.
Have you changed the sim cards with newer ones to rule out some old SIM cards issues ?

Yes, tried a SIM swap, still no CA on Vodafone.
4G+ should active automatically when network have these combinations available on network: https://cacombos.com/device/M2102K1C . Chinese devices doesn't support all 4G Carrier Aggregation combinations used in Europe so that could be reason why you don't see 4G+ active.
That's why it's recommend buy Global version: https://cacombos.com/device/M2102K1G

If this is the explanation, i guess there is nothing to do except switching the chinese for global version ?
I think we're just waiting for someone to try the global or EEA version, not brick their phone, and report back on whether CA is now active.

I hope im wrong but i think when it comes to network bands its only about hardware , not software .
Hopefully this can be fixed by software stuff but i doubt it .
Before i bought the phone , i checked bands support and all the UK ones were supported . But it looks like things are more complicated than just supported bands .
I believe CA is a software issue, as the modem just need to know which bands can be aggregated together.
I just downgraded to the Global 12.0.1 version and still no CA.
Well , if someone could tell us what are the odds of this being somehow fixed in the future , i would be really grateful. If there are no chances for some fix , i will definitely sell it even though i freaking love this phone .

Well there is not much todo because CA combinations are defined in modem firmware. Changing OS to different version may not change modem firmware.

These are configured to modem firmware. You can't change these values because it requires source code of modem and then compile it. We don't have modem source code so we can't change carrier aggregation combinations.
So only what we know is support per devices - https://cacombos.com have good database
Considering this , anyone from UK wants to buy a Mi 11 Ultra 12 / 512 ? Thanks .
Just tried a Global version, and 4G+ works fine.

And the CN version:
So moral of the story, it's not just about the LTE bands it supports. I'll know for next time!
