P9 4G+ : inter or intra band ?

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?

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...

I also have p9 l19, but I'm quite certain I saw 4g+, before I updated it (I just yesterday bought it) and now all I see is 4g. My carrier supports those bands

I can confirmed about the 4G+ icon

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

A3010 (China Variant) Carrier Aggregation Issues

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

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

Exynos variant

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 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.

G977N and 5G not working

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!

volte works on the v40, but it's not as simple as that. If your carrier is so-and-so, they allow it with their phones, but not others. Some carriers allow it with bring-your-own device, some don't.
you don't say what variant your phone is other than405UA, that could be sprint, vzw, att, etc.
you don't say who your carrier is. How can anyone help you? There isn't some 'magic switch' somewhere

Well the first and most important thing you need to know is if the phone is 'Carrier Sim Locked'. In other words, if it is sim locked to AT&T, then the only way it will work with another carrier is if AT&T unlocks it for you.
IF the device is not 'carrier sim locked', then for you, because of where you are, would want to flash a kdz that has the 'bands' that your local carriers use.
If it is sim locked, don't flash a kdz rom to the device, because the software needed to unlock it is part of the ATT rom. If you flash over that, you'll lose that software and have no way to carrier sim unlock it.

So long as you think it's carrier unlocked, then follow this thread to cross-flash to a different rom.
keep in mind, your carrier has to also support volte and vowifi for it to work. Even though the phone may be perfectly capable of it, if the carrier doesn't support it, not gonna work.

My original thought was to get a 6 dollar a month tmobile and get 4 lines gig of data each. Unfortunately, in Cleveland ohio, tmobile sucks compared with verizon and att, forget it outside the city off the highway, without band 71 600 mhz. My kids wouldn't take the phones and plan.
I also tried verizon, page plus, but they won't activate it, and saying not volte capable. with tmo, I was thinking data only. But on page plus, I want calling.
