I don't know why it is not by default.
Very important feature.

I have a MI8, formerly a Huawei P20Pro, same operator, Vodafone Spain, same SIM card, with the Huawei in the center of the city sitting in a place, at the same time, clear days.. and HUAWEI 4g + and MI8 No, does not pass LTE, 4g.. does not go to 4g +, LTE ADVANCED, and can say all the pages of the world that is 4g +, which is not true, does not combine the band B20, with none, and in Spain is essential to have 4g +.

Well, for me there is working LTE+.

also for me is working, i'm on Xiaomi.eu 8.11.8

band20 becomes active first. No band20 at Mi5s. so LTE+ is active.

No, never tried.

I'm in Indonesia and I can confirm that I have 4G+ enabled by default for both SIM slots. I'm using Telkomsel and Indosat and both of them confirmed works on 4G+ when the networks are available.

The point is that in some countries intra band doesn't work, so now on mi8 i haven't 4g+ where i had 4g+ with other phones. That's it.
In some places and with specular phone operators it reaches 4g+, but it is another story.

Because in your country Xiaomi pay licenses at Qualcomm, not in mine where mi8 is sold officially.

The problem is intra band and it's real.

As milan03 stated, the bands are incompatible so LTE will not work with AT&T/Rogers/Bell. You will need to use the correct APN for your carrier if you cannot send/receive MMS messages.

[Q] LS990 Spirit which is unlocked would work on ANY lte/gsm?

Hi,
I almost close to buy this model.
I will pass it to a person that lives out of u.s.
The LTE network there: 2600/1800.
The GSM network there: 850/900/2100
He told that the phone is unlocked and he also figuerd it with Sprint.
They (Sprint) told him it will work in any county.
Also mentioned something with "Unlocked by EOD".
BUT:
When i read the specs of the LS990 I see under :
Network: GSM Quad Band/UMTS Tri Band/LTE Tri Band
And Under:
Frequencies: GSM 850/900/1800/1900 MHz, UMTS 850/1900/2100, LTE Bands 25/26/41*
I can see that:
GSM - V **The Quad Band is aint someting exclusive to Spirit or U.S networks, right?
UMTS - V **The same regarding the " Tri Banad"
LTE - V **The same regarding the " Tri Banad"
And i can see that the LTE of this model is not something i know heard about in ISRAEL.
We have here 2600 & 1800 frequencies
With all that info' - can u confirm this model is like factory unlocked to work within ANY GSM & LTE global?
Thank you very much!

Sorry, not all of us are into "this world".
What does "locked down" means in my case?
By the way - the phone comes with a SIM-card slot!
Thanks for your help.
P.S: read this article and looks like it is possible to make a sim unlock within Sprint:
http://www.androidpolice.com/2014/0...ruary-11-2015-onward-domestically-unlockable/
Look, in the simplest of terms, the Sprint LG G3 is not the model you're looking for. It is not unlocked out the box, and is difficult to unlock properly because it is done through the service provider, in this case Sprint via an OTA method.
Get a proper GSM version.
Final answer i've got from Sprint:
They confirmed the phone will work in any other country.
That the phone is unlocked, that the procedure turned the LG G3 phone to a factory unlocked by all matters, to be used globaly by any LTE / GSM network.
And all i have to do is buy an 128k SIM card in my country and it will work with any carrier.
The rep' said: "it has been Unlocked and will indeed turn the LG G3 phone to a factory unlocked by all matters, to be used global by any LTE / GSM network."
I just need to turn some setting...that's all.
Hope that the rep' is right...but i talked to them few times regarding that thing.
Thanks very much!

Sorry bro. No Hebrew. I would have recognized it. Double checked right now.
Thanks very much.
Do U know if it possible to add an unavailable right to left language for a model that specifically produced to the U.S market?
One more thing is: Read that theIr are lang's which are builded in , But the provider is just BLOCKING part of them.
So in order to fix that - I shell install the zip of the MoreLocal2. (not the app).
Saw a guid on a Galaxy Note which worked on it.
Anyone know's if it supposed to work for any Android?
Thanks again.
So, I got a LS990 in Canada which won't find no LTE networks in Canada. Bell in Canada operates on 2600 and 1700 while LS990's standard is 850/1900/2500. So, I basically hate this device and didn't want to believe the fact that LTE bands had hardware dependency though these are world phones. It sucks but I would still appreciate if someone could prove me wrong.
Thanks!
Here's how to unlock additional bands. I haven't tried it as I'm not needing to unlock more bands, but it's something to read about.

Poco F1 US LTE Bands 2 & 4 Unlock Possible?? (No Longer Being Pursued)

Current Status as of 10th Nov 2018 - This effort is no longer being pursued.
Mi 8 qcn is available (thx to @JR_44) https://forum.xda-developers.com/showpost.php?p=78020802&postcount=184

This effort is no longer being pursued. You have @jaimani on xda and also xda (@MishaalRahman) works with Poco in providing free devices to developers so maybe they can ask Poco if this is even possible.

Original Post
The Pocophone F1 LTE bands are listed as
1(2100), 3(1800), 5(850), 7(2600), 8(900), 20(800), 38(2600), 40(2300), 41(2500)
However, it is supposed to launched in Mexico and Colombia as well.
Mexico LTE Bands - 2 & 4.
Colombia LTE Bands - 4 & 7
Band 2 and 4 will be very helpful for us US peeps.
Not sure how Xiaomi locks the bands, do they use software? in which QPST should be able to unlock the bands.
or
They lock them via hardware, in which case Poco F1 will have a different model from Mexico and Colombia (and other countries which use Band 2 and Band 4?
QPST
https://forum.xda-developers.com/redmi-note/general/unlock-lte-bands-step-step-xiaomi-mi-t3084774
If anyone with a bootloader unlocked and rooted Poco F1 is willing to try QPST and see if the bands can be enabled please post here.
Thanks.
Also following for the answer. Bands 2 and 4 would make it quite viable for T-Mobile service in the US.
Phone has indeed been announced for Colombia (where LTE band 4 is used) and it's already going through Colombia's own certification authority. I would assume that we might be facing a similar situation as with Mi A1 in that the manual said it didn't support LTE band 4 (check the post I just linked to) but on first setup if you chose "Español (Mexico)" as the language, it would enable LTE band 4.
its sad that this phone with the flagship qualcomm sd845 should handle universal lte bands, but somehow in xiaomi phones specially the LTE bands are pretty limited, for example here we use band 28 (700 mhz) and there are no support for that

Hadn't heard about this, with the Mi A1. Very nice fudge, this. If the F1 can be wangled to use band 4 it will be a shot in the arm for north American interest and development

Change The región to Colombia or México. And try again.
Just like mi A1.
It'd be great if someone could try band 12. The lack of that band is a deal-breaker for T-Mobile in the US on my Mi A1.
Nobody has been able to enable band 12 on phones that don't officially ship with it. This has been the case on the OnePlus One, Mi A1, Mi A2, and more. You can "enable" it in QPST, but it doesn't work.
So, this phone is a no-go for AT&T LTE in the US? Might have to return it if it only supports band 5... shame, I really like the idea of it! Maybe there's a way to enable more bands, but from the other poster, it doesn't really look like it.
whats odd is they disable face ir for other regions

LTE Advanced in Europe??

I have been testing and also read on official telegram group that carrier aggregation (4G+ or LTE-A) is not enabled in Europe.
Will there be any fix for it on future updates? Phone is listed as CAT16 but its working as a CAT4.
Any idea? Was Poco community manager on forum? Would be nice to know if Pocophone will be CAT16 in Europe or just CAT4.

With *#*#4636#*#* you can see connected cells, or some apps for cell monitoring, it doesn't use never more than one band (EARFCN is the frequency of band used). Could maybe be a CAT5, that it's like CAT4 but supporting MIMO 4x4, but the most standard is CAT4. CAT6+ are all LTE-A with carrier aggregation, what Poco doesn't support in Europe bands. (some info in http://main.rfassurance.com/?q=LTEUeCategory )
Also I work on mobile network engineering, so I have some info from network, but it can be easyly checked from phone, no network aggregation = no 4g+ or LTE-A
my problem was solved by a call with three austria service line.
in fact they didn't get band 20 frequency by auction, only 1800 and 900 for volte calls only.
https://www.rtr.at/de/tk/FRQshare
so, I'd have to change my provider (telekom or t-mobile or a sub) to get band 20.

so, I'd have to change my provider (telekom or t-mobile or a sub) to get band 20.

It's not related to the lack of carrier aggregation for Pocophone in Europe. My provider uses bands, 3, 7 and 20, in a cell with the three bands and that allows carrier aggregation between all them in any order, doesn't work at all while works with another phones.
Btw, installed new MIUI10 open beta, and problem is still there.
@ PocoCommunityManager are you there? Any info?

There is not 4G+ for Poco in Europe like on most xiaomi phone, stop to ask.
I don't think asking is a problem, Pocophone lists the phone as 4g+ in Europe (example: https://www.poco.net/es/specs/ or https://www.mi.com/es/pocophone-f1/specs/ ), so we ask for it.
SD845 allows it, probably it's a fw thing, not hw.

I mean, there is 4g+ but only in special conditions, very rare: it's as if it were not there.
Any chance someone from Poco team could answer this? Other phones using perfectly 4g+ and Pocophone fake CAT16 doesn't at all?
My internet is slower on pocophone than in my last phone, Xiaomi mi a2. And both have band 20, then i thing that is a rom problem.
I think more band combinations are available with MiUi 10 because after the update it's showing me 4G+ on a network.
I'm also having the same problem in Europe. It just wouldn't connect to 4G+, not like on other phones. My operator supports 3+20 and 3+7+20 band carrier aggregation. LTE Discovery app shows that the phone is always connected to band 3 only.
Up !
I wrote about this problem in the main pocophone forum and to be honest there is no real official reply. Some people wrote that CA is disabled due to pocophone not buying proper licences from Qualcomm.
It's difficult to say how accurate this explanation is. One thing is definite, they advertise pocophone as LTE cat.16 capable and at the same time they disable this feature completely and limit capabilities to LTE cat.4 (not even cat.6 ....). This is not what you call honest marketing. More like lying about you product capabilities. I think CA happens but only in India or in some extremely rare cases in some other countries, especially if certain phone companies offer CA on frequencies similar to indian frequencies.
No developer can activate this option? With a custom ROM or something? The sd845 supports this though!
Any update?
they are not interested as usual. flagships in Xiaomi's term: "yeah it's fast but that's all. buy it then don't ask CAUSE IT'S FAST OKAY?"
Why is this thread inactive? I live in Greece where carriers use 3 7 and 20 for 4g although poco is always connected on 3 as stated. Has anyone tried to enable 3CA using QPST?
I usually get connected to band 3 or 20.
I'm in Spain. To make sure I'm using band 20 I switch from 4g to 3g and back to 4g Enmidiately. Screenshots attached.

4G+ and Volte In Europe Countries

We all know that Poco F1 is capable of 4G+ network and Volte.
Many European Countries have coverage of 4G+ networks and Volte services.
I am from Greece, asked official dealer of Xiaomi in Greece and they claim that Poco is 4g+ capable (as all we know) but in 4G+ capable network (GR Cosmote) there is no 4g+ coverage with poco. Previous phone was S9+ and had both 4G+ and volte services.
In Greece and at many Eu countries 4g+ coverage comes with aggregation at bands B3+ B7 which poco is capable of use but maybe not capable of aggravate them.
Who knows...
Has anyone problem like this?
Concerning volte, one friend of mine with redmi note 5 pro, updated phone to 10.0.2.0 and has volte services.
Do we wait an update for this volte service?
Thanks and waiting for answers

If u r rooted, try adding these lines to Ur build.prop and it will enable VoWifi.
I have it enabled in my phone but cannot test as my carrier doesn't support it.

Thanks for that.
Enabled Volte, but no access to it on Tesco Mobile here in Ireland despite being on 4g+
I think more band combinations are available with MiUi 10 because after the update it's showing me 4G+ on a network.
How do I check if volte is activated? I'm on three
O2 germany and both working
