LTE Cat and LTE Carrier Aggregation / Bands Support of RN7 connected mainly to built in Snapdragon 660 MSM8956 with X12 LTE Modem Features (also in Snapdragon 63x/66x/820/821): 3CA Downlink and 2CA Uplink, LTE Category 13 (uplink) 12 (downlink), Download 600 Mbps Upload 150 Mbps. So far unclear if device drivers fully support this in RN7.
See also about the same topic in Xiaomi Redmi Note 6 Pro Thread.
So far for LTE Bands I found this - always difficult to see if (also) International/Global version:
GadgetsNow: TD-LTE 2300(band 40) / 2500(band 41) FD-LTE 2100(band 1) / 1800(band 3) / 900(band 8) / 850(band 5) / 800(band 20)
techwafer: LTE band 1(2100), 3(1800), 5(850), 7(2600), 8(900), 34(2000), 38(2600), 39(1900), 40(2300), 41(2500). LTE-A (3CA) Cat9 450/50 Mbps.
Checking the Bands for my provider Central Europe (in bold supported): 3CA (B3+B20+B7+B1) and 2CA (B3+B20/B7, B1+B20) + B32. So CA seems very fine!
LTE General: Cat9 450/50 seems not so exciting compared to RN6P with Cat12/7 (600/100 or 300/150?) because the upload could be higher like Cat10 (450/100), Cat12 (600/100), Cat14 (400/100)?
Here are the official speces for the global version:

Ok, so there it is stated what I already wrote earlier (I bolded those important to me, all except of B32 supported):
FDD-LTE B1/2/3/4/5/7/8/20/28
TDD-LTE B38/40

No mentioning of LTE Cat or Download/Upload Speeds.
So has anyone tested and confirmed LTE-2CA or LTE-3CA really works with RN7 ?
whether the CA support for RN7 is interband or intraband or both ?
and what CA bands are supported ?
am hoping for (B3 + B7) or (B3 + B7 + B8), different countries/carriers have different CA bands.....so would be good to know what CA bands are working/supported by RN7.
so if anyone got LTE-CA working.....please post here to share the bands info
Anyone can confirm CA (band 3 + band 7) is working ? or any other band combo ?
please post here to help everyone get the info
Bonjour, je vis en France à Angoulême et je peux vous confirmer qu'avec un Redmi Note 7 Version Globale (4go de ram / 64 go de rom) je n'ai jamais la 4G+ avec Orange.
Fréquences 4G à Angoulême : B3, B7, B20 (1800, 2600 et 800 MHz).
J'ai lu cependant sur un site que le carrier agregation fonctionnait avec le Redmi note 7 uniquement en 2100+1800 mhz (en interbande) mais malheureusement je ne peux pas le tester pour l'instant.
Bonne fin de journée

Summation : how to support china ver op2 FDD-LTE band8
Can anyone tell me the difference between wt88047 and wt86047? And does this relate to model numbers like 2014813 or 2014817 etc. Thanks!
2014811 is China Unicom version, most common sold by Chinese resellers. It supports.
4G FDD-LTE(B1 2100MHz / B3 1800MHz)、TDD-LTE(B41: 2555-2575MHz)
3G WCDMA(900 / 1900 / 2100MHz)
2G GSM(900 / 1800MHz)
2014813 is China Mobile version. It supports
4G TDD-LTE(B38 / B39 / B40 / B41: 2555-2655MHz)、FDD-LTE(B3 1800MHz / B7 2600MHz)
3G TD-SCDMA(1900 / 2100MHz)、WCDMA(850 / 1900 / 2100MHz)
2G GSM(900 / 1800 / 1900MHz)
Those are the main 2 version there is also 2014818 wich is the Indian version no other differences except the ones above
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.
Hi all,
I have a Moto G5 Plus (XT1687) running Android 8.1.0 with build number OPSS28.85-17-6 and would like to know the supported bands for LTE-A Carrier Aggregation.
Thank you,

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
Has anyone here connected to LTE-A or CA? Here in Brazil we have the bands B1, B3, B7, B5 and B28 on TIM carrier, but it is connecting in just one band in a time. Software limitation? I saw that the SD662 supports CA. Would it be possible for a custom ROM to solve this problem in the future?
