[SOLVED] As a check that is the phone version?

A friend Buy on ebay the phone with TW Version.I received the phone but check the compilation is WW version and the SKU is WW Version (Flashboot mode). The phone allows me to upgrade by FOTA, offers me the latest version. The box I do not have to check which version came with factory.
1) As I can see if the phone is TW version?, because I need to use the LTE BANDS 4 and 28.
---- SOLVED ----- I could check with the SN in that version is asus

Us versions are based on snapdragon processor, International is exynos, also they both operate on different radio frequencies, so I can't take my international device over to us and put a us sim in even if it's unlocked to all networks. VoLTE is carrier specific and if you wish to use it you will need to flash that specific carriers branded firmware if it's available for your variant. South Korea has it's own variant, you can't use a Korean sim in a us or international device, that's as far as I'm aware, someone can correct me if I'm wrong.

Change LTE bands of A2017

Hello everyone, I have a question
I have an Axon 7 A2017 but being the Chinese version, the LTE bands are not the same as those in most of the operators in my country (Chile), since it does not have band 4 (1700-2100).
If I install a rom A2017U on my A2017, as in this guide https://forum.xda-developers.com/axon-7/how-to/guide-transform-chinese-a2017-b107-1-1-t3575320,
Can the bands be changed to have the LTE bands of the U version?
Is there any way to achieve that?
Thanks:good:

Nope, you can't change LTE bands on Chinese version

RN7 Globe version vs EU, confused !

What's the difference between the 2? I purchased a globe version but it came with
MIUI Global 10.3.2.0 (PFGEUXM) with April Security Update. I am confused because I think only globe version has the additional LTE Band 2 and 4 that I need in the USA.
The model # is M1901F7G

Where did you but it from?
Did your seller confirmed they sold you the Global Version or was it a China model masquerading as a global version?

Hello,
The hardware model of "Global Version" of RN7 (Lavender) is M1901F7G:
4G Bands: B1 (2100), B2 (1900), B3 (1800), B4 (1700/2100 AWS 1), B5 (850), B7 (2600), B8 (900), B20 (800), B38 (TDD 2600), B40 (TDD 2300)
But there are two versions of ROM MIUI
Redmi Note 7 EEA (yours): PFGEUXM
Redmi Note 7 Global: PFGMIXM
Take a look: https://en.miui.com/download-360.html#591
Regards!!

Good to know the hardware is the same for both EEA & Global, first time to hear EEA is the European ROM. I search high and low but no one seems to know the different except likely apps. I am not too concern now since I debloated most of the Mi apps/ads and turn it into pixel like phone
I got mine from Aliexpress, and at the time of purchase, there were Global ROM version (will not work in the USA, no LTE band 2 and 4) and Global version. I didn't know Global version actually has 2 versions which split into EU and Global.
Thank you

Yes , PGFEUXM is European Rom , I have Global version PFGMIXM.

EU have its own, most likely, because of GDPR and other privacy stuff.

XT1687 is a US model so;
LTE B2 (1900 PCS) AT&T
LTE B5 (850) Tmobile
LTE B12 (700 ac) T-Mobile
LTE B13 (700 c) Verizon Wireless
LTE B25 (1900 +) Sprint
LTE B26 (850 +) Sprint
LTE B41 (TD 2500) Sprint
LTE B66 (1700/2100) T-Mobile
And I think T-Mobile and Sprint just merged

Thank you @Nivead,
There is any way to change the radio frequencies, to support contiguous carrier aggregation on band 3, 1800(CA_C3)?
Regards
Rafael

If you have rooted device, you can check supported combinations with Qualcomm internal logging. Here is instruction: https://mt-tech.fi/en/how-to-get-4g...from-your-android-phone/#Qualcomm_diaglogging . You can then share log to me so i can then parse log file and then can list supported combinations.
There is no easy way to change carrier aggregation combinations because these are defined to hardware. Theory possible modify some NVitems but this could brick your modem.
There is different variant support 3C: https://cacombos.com/device?model=XT1805
