What is your firmware country ?

I am in the US, using CE firmware and getting LTE+ on T-MO

Middle East
And my operators are IR-MCI and MTN both on LTE+ (MTN perform better MCI. My mci some time switch to 3G)

I have checked the kagura dsds device available modem configuration files and the capability seems to be upto 3CA as same as for single sim one.
So the available 2CA(cat6) and 3CA(cat9) band combinations should same as in my thread https://forum.xda-developers.com/xperia-xz/how-to/lte-carrier-aggregation-combinations-t3577544/
Find your your country MCC and then you can see which list it is part of. Then see see available CA combinations for that list.

Probably bevause when it was released, 4G was prevalent in India.
I know, it has 3 bands of 4G, none currently used in India, so no way to use 4G in India.
should we not sue HTC India for selling a device with false pretense? When I called HTC, they said their devices are country specific. If so, why is HTC advertising it as a 4G device if it cannot be used even in India?

Thought so too, but their website clearly says 4G only available while roaming. So we'll have no ground. And the clearly mention which bands too. I don't remember where they advertised it as a 4G device too.

As far as I know, none of this will work until htc sends an update to enable 4G, like it did with the M8. It initially didn't support 4G, but an update was sent to enable it. That brought LTE under the options in network, whereas we have only 2G, 3G and CDMA. LTE should be there for LTE to work.
Also, from what I've heard via someone close, htc isn't considering the update, for them, E8 in India doesn't support 4G.

Vodafone India 4g Issue

I have honor 6X indian variant.My 4g connection works fine when I am using Reliance Jio carrier sim card.But when i switch to my vodafone simcard i am unable get 4g data speeds.I am able to view vodafone 4g network and connect to it.But when i turn on my mobile data i am only getting 2g or 3g speed.I have talked with customer care , rechecked my vodafone internet settings they all are fine.Vodafone is set as primary sim and 4g is enabled.Even my subscription plan is 4G plan i have checked.Can anyone help me to resolve this.
Update : 11/09/17
Yesterday i got update BLN-L22C675B340 , after installing there was no immediate change. but today since morning i am able to connect to 4g network all right. Don't know if it was due to carrier issue or phone software issue but its has gone away now for good.
Maybe you live in an area where Vodafone have no band of LTE that's compatible with your device
im using idea 4g. i do get 3g speed sometime when there is no 4g signal but at my home i alway have 4g i got good signal at home.

So this makes my conclusion a logical one, Vodafone doesn't provide a 4G band that's supported by your device in the area where you live!

Kirin 970 processor present in the Honor View 10 is the Worlds first mobile SoC that supports Cat 18 LTE. It can attain maximum data speeds of 1.2Gbps. In contrast, Qualcomm’s Snapdragon 835, supports Category 16 downlink LTE, and can achieve maximum download speeds of 1Gbps.Tthe Kirin 970 is capable of aggregating up to 5 LTE (5CA) downlink carriers & phones equipped with this chipset will likely achieve even higher data speeds once carriers start supporting this technology. So basically it future proof. Even the OnePlus 5T supports only upto 3CA.
CA related question
Is there any tool, app, code to see between which 4G bands the device is "making" the CA?

The carrier aggregation option is missing from my phone, lol - B140 C432 (Europe). My OnePlus 5 had LTE-A all the time (the 4G support on my mobile provider is on 1800 and 2100 bands). Since I got the View 10, I have not seen the LTE-A sign not even once, always stuck on 4G only. A friend of mine has Mate 10 Pro and he gets LTE-A. Same mobile provider, same chipset.

I'm going to assume your carrier is an MVNO such as Metro PCS, the most problematic carrier with this device? If not, what carrier do you use?
Most of the times the fix is pretty simple. Go to Settings > Cellular Networks (make sure under Preferred network type LTE is selected) > Access Point Names and chose your correct APN. Is it jumping back to the incorrect one? Delete that incorrect one and any other ones that are related to the "parent" carrier and then chose the correct one. You can delete it by going into the APN as if to modify it and tapping the 3 dots on the top right. Can't find your carrier's APN? Delete all APNs one by one, then add yours, save and and select it.
If the above does not work, ensure that the OPO supports your carrier's bands, specifically for LTE.

Sorry for the late reply. According to information I find on the web, Tesco Mobile uses Band 20 for 4G, which the OnePlus One does not support. Other websites mentions it using Band 40, but I believe this is based on the fact that O2 (the parent carrier) has obtained this band and may not be fully implement on the MVNO (Tesco Mobile). I would suggest calling them to find out what 4G/LTE band they use. If they use Band 20 (frequency 800MHz), you will only get 3G, or HSPA/HSPA+ (H or H+ icon for your data on the top right). If it supports Band 40 (frequency 2300MHz), then we can try and see what is going on that may be stopping your 4G/LTE from working.
they use 800

Yes, sadly that means Band 20 for 4G LTE, which the OnePlus One does not support. You will only get 3G. Some carriers call HSPA+ "4G" because it can achieve decently high speeds for video streaming and so on, which isn't bad.

Carrier Aggregation after Latest update? (India)

I am getting LTE-A in Net monster app after the latest 10.2.10 update in India. Anyone else getting it?
Update: I rooted my phone and viewed the RFNV CA configs. It was set as 0 means no CA. I set the required value, first for intra band, and then for interband. Both of them didn't work. Confirmed this in Network Signal Guru App. So sadly no CA for us cz of hardware limitations.

Net monster doesn't prove u have it. It does say that it's supported in your area. I have checked the carriers with Network Signal Guru App. There is no carrier Aggregation. I even checked the speed comparing with poco which has 4G+. speed is really low compared to that.

still my bootloader unlocked. so wait
give your net guru screenschot
my device bootloader unlocked and rooted.
Network Signal Guru 2.8.1 app only support SoC 675 . ( but not fully). so cannot show anything. please wait ..
xaimoi say its 3ca support.
If NSG doesn't work on your phone, you can maybe get modem log from Xiaomi. I have instruction here: https://mt-tech.fi/en/how-to-get-4g-supported-ca-combinations-from-your-android-phone/ (scroll down to Xiaomi section).
If you can send log to me, i can put this device to my cacombos.com website where you can easily see supported Carrier Aggregation combinations of many devices.
