As for the title, does the Mi 5 LTE+ is using interband CA or intraband CA in stock ROM/any custom ROM?
Since my country carrier is using band 3 and band 7 LTE mostly, and my current carrier claim that they using interband CA (although it's still LTE CAT 4, so the max bandwidth they do support is 20 Mhz) so my Mi 5 can't use their LTE-A hmmm

Hi, what's the difference between them? Also in my country there's the aggregation of b3 and b7 and with my mi5 I have never had 4g plus..

Interband is B3+B7
Intraband is B3+B3 or B7+B7
However after I research awhile and found that Mi 5 does can support Interband CA since just now I read from Taiwan forum, both Taiwan Chunghwa Telecom and Japan NTT Docomo can use their CA in Mi 5 as the attachment shown below
And both operators are using Interband CA, their config is show below:
NTT Docomo: CA_3A_19A, CA_1A_21A, CA_1A_19A_21A, CA_1A_3A_19A and more
Chunghwa Telecom: CA_3A_8A, CA_3A_7A_8A
And as for what I search, B7 have poor signal distribution, as for my operator I'm most seeing the B3 but B7 is really seldom come out

I can assure you that b3+b7 doesn't work with mi5. I tried really hard to find out a solution but I never succeeded.
http://en.miui.com/thread-360460-1-1.html
This is a post in miui forum where other people had the same problem.. I also chatted with all the dev team trying to figure out something.. Is there something problematic with that and I don't know what it is.. (b7+TDD frequency bands works)

But then with the Taiwan Chunghwa Telecom, their band is all FDD band, why in some post they reply it still can detect LTE+?

I honestly don't know, during my searches someone said to me that the problem is the kind of the spectrum (continous or discontinous). Don't ask me what does it mean cause I don't know.. Maybe this is nothing but that's the only answer that I found.. I tried with 3 different phones and I got the 4g plus, with mi5 no 4g plus. I tried all roms (china, global, third part roms) no 4g plus.. Just with b3+b38

Just now I'm also found that the spectrum distribute by my current carrier is also kind of hairwire, inside the house they are almost all B3 while when go to outside the house hey are almost all B7
This is kind of weird, and according to some forum they tell that my current carrier is really doesn't display 4G+ in major phone as they using 10MHz+10MHz (CAT4) which results some phone may just detect it as 4G signal

No way, that's not possible cause I checked with lte bands and I also checked the band used and I know for sure how much Mhz my carriers use in my country and that conclusion is not possible. I also have proofs that mi5 has no problem in detecting 4g plus as the sum of more bands with photos of lte bands logs.. I think that this problem is underrated and I found just few people to talk about it
I got some news, A friend of mine said to me that intraband is the sum of near frequencies (such as b7 and b38), this kind of aggregation is possible in every condition. The interband aggregation (such as b3 and b7) needs a chip called companion that helps to sum the download of distant bands (b3 and b7). Probably the mi5 does not have this kind of chip and so the only possible CA is the one with near frequencies.. I also tested it and it works. I don't know how to confirm this anyway but it makes a lot of sense.
Hi,
I bought an one plus 3T in india and brought it to US. I'm getting only E not even 3G. When I enquired in T mobile/lyca store, i was told that india unlocked mobile won't support the US bands. Network upgraded. It was big surprise to me. Please suggest me how to unblock additional LTE bands in my 3T mobile.
That's not possible, you should trade your 3t A3003 for a 3t A3000 American band-unlocked model.
Check the specifications for each model under connectivity.
https://oneplus.net/us/3t/specs
Wait, what?
I live in Sri Lanka (Tiny country below India) and my 3T is the Indian device. I toured Europe for 2 weeks, and I used an O2 Sim, and used LTE in Europe for the whole time I was there. Have you tried going to Settings, and selecting "LTE/3G Only"? That may fix your issue.
I swear, there should be no issue with the bands.

India uses FDD 850, 1800 and TDD 2400. Most of the Europe uses TDD 1800. So you getting LTE in Europe is not a surprise.
USA uses 700, 1700, 1900, 2100, 2300
Varies with MSP
You will at least get 3G with T-Mobile and AT&T

Europe and india uses the same bands. I lived in uk and used the uk phones in india and indian phones over there. Its the states that uses different frequencies so most of phones don't work properly outside states.

Compatibility of phones with the cell networks in the US are a total pain in the you-know-what. We have 4 different major carriers, all using different bands (a little bit of band sharing, but most completely different) for 3G and LTE (GSM is a little more standardized thankfully). Basically, as a general rule if a device not intended/designed to work on US (and depends on which exact US carrier), you are probably going to run into some incompatibilities (no 3G or no LTE, or limited connectivity).

Talk about synchronicity eh? But do the difference in bands give any speed differences, or call clarity? In the blind about these stuff, coming from a country that has only one carrier out of five who is still beta testing VoLTE.

Not an expert, and had to Google that. From what I'm reading, lower frequency (MHz) has better penetration (through buildings, etc.) while higher frequency bands have higher data capacity.
There are steps on how to unlock additional bands. There are like 50 steps. I dont remember where I've seen it but if you google how to unlock bands on OnePlus you will find it. Also try to flash Oxygen OS from US web site which I see no reason to work but just a suggestion lol

There are no region specific versions of OxygenOS, so this will do nothing but reflash the latest update.

There are no steps at all. You cannot "unlock" bands, as they're hardware related. There's no way to switch bands out of the blue.

At one time that was true. But for Qualcomm SoCs, the band support stopped being set in hardware (at least for the most part) some 3 years ago with Snapdragon 801 (or maybe earlier, but definitely with 801). Support for all or most bands (might be some exceptions) used worldwide is there, but the specific bands are enabled in firmware.
https://www.qualcomm.com/products/rf
That said, enabling bands is a long process as noted; and has the risk of resulting in a radio brick. So it's best to buy the correct region version OP3T (which supports the needed bands out of the box) when possible.

Why aren't all bands just enabled by default then? I don't understand why there are different models for different regions.
I have a US OP3T and I'm visiting India. It''s working with Jio in India (although it supports only only of the 3 bands used by Jio) but VoLTE doesn't work for some reason.
Hi. Could somebody test if this smartphone does intra-band and inter-band carrier aggregation with B1, B3, B7 and B20 bands?
Thank you in advance.
It does with B3/B1, B3/B20 and B3/B8 as far as I could test

I tested this on T-Mobile NL and KPN NL. At my work, I receive a B3+B1 Transmitter and it shows CA which is a sign for me that the phone support this combination. At my home, the local transmitter has B3+B8 or B8+B3 depending on how weak the reception is and I still see CA on this phone. On KPN NL, I have at various places CA from which I know this is B3+B20 or B20+B3, when B3 is weak.
Since this phone has the Snapdragon X12 modem, which I also had in my former HTC 10 which was rooted and I had a diagnostic tool for Qualcomm on it, I am pretty sure it has the same support of CA bands. as I see CA on the same places as before with the known combinations.
Thanks, what shows CA? Are you using Network Signal Guru?

Hi all,
someone know why xiaomi don't enable 4G+ on Mi A2? the SD660 is capable of it
maybe xiaomi should pay for using 4G+ license cost on Mi A2?
I've submitted a request, please confirm it here
I have 4G+ so nothing to complain here.
I have 4G+ too.
I'm in Italy and I do not have 4g +, is there a way to unlock it?
I was in Italy a few weeks ago and had 4G+ in the Milan region. So it also works in Italy.

The Mi A2 supports 4G+ ( LTE-A or Carrier Aggregation ) out of the box, it just doesn't show the 4G+ icon like some other Android phones.
Stock Android by default, like on Pixel devices, shows only LTE or 4G.
Attatched picture shows stock Mi A2 on the latest September update using both 2600Mhz + 1800Mhz Carrier Aggregation.

Hello everyone!
As far as I know there are two versions of the Transparent Edition Mi9
8/256GB and 12/256GB. The 12GB model was the first one with the difference in the storage and RAM and it has a 7P elements 48mp camera instead of the 6P on regular Mi9 models and it has a bigger aperture one as well with F. 47.
On March 22nd Xiaomi released the 8/256GB TE model which has the same camera tech as a regular Mi9 but it has the B20 LTE modem which is used in Europe.
Does anyone know something about this? Am K true? That the 8/256GB model is the 'global' version of the Mi9 TE?
If anyone knows something about this please let me know!
No band 20 on either TE versions, as far as I'm aware...
Where did you read this?
On some websites written in my mother language (Hungarian). They were totally sure about the B20 in the 8/256GB model

Guys just look at the asian china site. In the specification of MI9 TE there is no LTE Band 20 .... so dont do this mistake when you live in europe..... you never can use LTE with this china versions of MI9 in europe .....
