I understand that for XT1103, the CA bands are 2+13, 2+17, 4+5, 4+13, and 4+17; for XT1100 3+5 and 3+8.
However, my country telcos only support 3+7. Is it possible to edit the CA bands for 3+7? Or is this a hardware thing? I'm using XT1100

Bands are completely hardware thing You can't change them
I see, thanks
What a waste for me, able to use LTE but not LTE-A

That is not entirely true. You can enable some bands.

Maybe ask the OP of this thread. He figured out how to add LTE band 1 to the Nexus 6.

It certainly worked fine on the Nexus 5 (enabling band 3 and 8 on the North American version). And although I haven't read much on enabling bands on the Nexus 6, I don't image it'll be any less effective.

Okay Thanks for the info btw
Nexus 5 still had some hardware restrictions for some bands. Some were possible to enable, some were not. Will require more investigation on the 805

For sure. But band 1 has already been enabled on the North American version, and @Azlun seems to be working on band 8. He hasn't mentioned anything about band 7 in his thread, and I have no idea about the carrier aggregation stuff.

Hello, I want to buy a xiaomi mi mix, since it would not support a band of 20, I would like to know with which operators you use the mobile phone. Thank you

I am using O2. I get H+ everywhere. LTE is impossible in the area of Essen. That's were I live.
EE, and BT work perfectly, Vodafone and O2 not so good, that's in the UK, so it sound's pretty similar to German networks.
Anyone using the mix with o2/eplus?`they should use B3/7/20 for LTE. So just in General is lte working on it in Germany?
No LTE 20 is not working, other LTE channels may work.Depending on where you are you will have limited LTE access or nil.
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

Hi, you're the first (and only?) one reporting this.
How did you test it and on which network?

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?

Ca shows the 4G+ logo on top, but I tested this indeed with network signal guru on my old HTC with the same mode.
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.

I'm in italy with Ho-mobile as operator, my plan is the first from this operator and include 4G+, newer offer is limited to 4G
xiaomi replied to my email saying there is a problem in aggregating lte frequencies in italy with Mi A2

I have TIM Italia and with my Honor 10 goes in 4g + but with This MI A2 only 4G..bah ..
just now discovered and try this command *#*#86583#*#*
after this in netwrok settings appear "modalita 4G LTE avanzata"
done some speedtest seem to go fast, but could be a coincidence

someone else of you having problems with 4G +?
same problem with orange slovakia operator. no 4g+ with carrier aggregation on 2600 + 800 MHz (CA bands 7 + 20)
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.
austria dada roaming phone show 4g+, on
my home home network only 4g.

What app is that?
it's NetMonster
I tried this app, and it showed me that I sometimes have 2CC or 3CC (800+1800+2600).
So carrier aggregation works really well.
Hello friends, it's been a while since someone posed the question below. I just bought a K20 Pro (China Version) from Aliexpress and only found out about the limitations of LTE bands. I was wondering if there is now a workaround to add LTE bands with a newer version QPST or another workaround/hack? If that, could we expect something in the future or am I pretty much toast?
You are toast. Time to buy a phone that's got all the bands you need. I'm in the same spot I need to give up on these POS international phone with almost 0 LTE bands for the USA.

I hope at some point there will be a hack, like there has been in the past. where are the geniuses on this forum ?
It's not about geniusness, it's utterly time wasting and requires a hell lot of effort which in the end doesn't guarantee it will unlock the bands, so next time get a phone with your required bands.

Didn't find any mention of adding LTE bands in the LOS thread. Can you point me in the right direction with a post number or page number?
I'm referring to the comments around the end of the first page on this thread (also continues to page 2)

**** these international phones I'm tired of them not having the bands we use in the USA activated. My mix 3 had every single LTE band and this K20 pro has 1 ****ty band. Why can't every phone have every band that people use in the world, is it really that hard?

If you look at the OnePlus 7 Pro bands you can see that it's easy, but brands don't want to do that for profits of selling a new phone when someone moves to a different country and so on, however I am not too sure why xiaomi doesn't have all bands enabled on the global version of the phone like OnePlus, I would understand locking the CN and Indian version, but the global should have all bands enabled
Engineer code qualcomm 855
Unfortunately, even if I've bought a MI9 T pro , described with correct bands & charger (need 4G B20 & B28) ; they send me a Redmi K20 pro with chinese plug... I opened a dispute but it drags on and I'm afraid of not having a commercial solution. So If someone did find a technical one ; I'd be very glad !
I saw some old techniques on Youtube, none of them works ; nor engineering codes (#*#*...) Is there a way to know them ? Thank you !
Good luck, but it's almost improbable, Even Pocophone failed.

This from the Network Signal Guru FAQs
Can you changed the band capacities of my cell phone. My cell phones are from other countries and the band capabilities are not so good, and I want more band support. Could NSG do that?
NSG cannot provide this kind of feature and we don't change the band capabilities. It's different among different phones, so it's dangerous and once failed, you will lose all of the band capabilities of certain radio technology. And it's very difficult to recover.
So, no it's not possible to unlock the bands.

Okay thank you
It's likely the bands are "hardware locked".
So depending on the region of the device various bands will be enabled or disabled. Every region of the device might well have the same modem - and that modem might support all the bands you want - but they won't work and there'll be no way of getting them to work as it'll be on a hardware-level.
It's why when you flash a Global ROM to a Chinese handset bands don't appear and vice versa. Both region ROMs will have their respective modern firmware but that doesn't change what bands you get - which would imply its literally hard-coded into the modem itself.
What I've read on the pocophone implies the band programming is locked, read-only, unmodifiable.
every site i check says mi phone can use lte in my country but i cant connect to it on my phone .... what do i do??
