Some apps falsely display that CA is running
Sent from my whyred using XDA Labs

Sounds like Xiaomi Note Pro 5 maybe support only Contiguous CA so this could cause you don't see 4G+ in your country. We can verify this from modem log. I have instruction here https://mt-tech.fi/en/how-to-get-4g-supported-ca-combinations-from-your-android-phone/ to get modem log out (scroll down to Xiaomi section).
Please send log to https://cacombos.com/contribute so then i can verify carrier aggregation support. In my page have many devices CA supports listed.

I want to know whether LTE+ and DRM L1 certification available on Realme X INDIAN variant

Change LTE bands (Unlock band 20)

Hi all
I bought a Chineese Version of the Redmi Note 8 pro. I installed now V10.4.1.0 Global Rom and it works. Last problem is that i need band 20 to have a good 4G connection.
Is it somehow possible that i can unlock and set this band ?
Kind Regards

You cant add new BANDS. China modem no support him !Re-flashing does not help!

Yes, but you have probably the global version. I have only 4G on the Chinese one. Until I go on holiday to China, where it will be 4G+!

Yes. I have EU version. I thought that I cant have 4G+ like on Note 7 , because this RN8 pro dont have all bands..

cool, but has anyone verified if changes in BandMode enable LTE bands? The G90T has the WorldMode modem and is capable of picking up just about every LTE band used throughout the world.

Redmi NOte 8 Pro has big problems with LTE 4G + tape management. The phone does not keep the 4G + it switches and stays in 4G all the time. It's a modem management problem that does not support the double-banding needed for 4G +.
Bests Regards

Hello, could you please specify what kind ofLTE band issues this phone have? I've just ordered Global vers. with 128 GB ROM, where Band 20 (800) is the most important for me, as it is the most frequently used one in Türkiye. It doesn't exist in my Mi5, so hope the signal and speed would be better with Redmi Note 8 Pro.

anyone played around with trying to unlock more bands? pretty sure the modem has the ability to get them all, and is just software locked for one reason or another

Even I go to engineering mode. It still cannot unlock the band 7 / 20.
it seem Chinese version cannot unlock the band.
I hope some expert can do it later and share with us.

what do you mean by "tape management"? If it's a modem management problem, then it is software related. Helio G9T's HAVE the WorldMode modem, what you're describing doesn't make sense and doesn't answer my question.

it's probably a modem firmware issue. the problem is the Helio G90T is only available on the RN8 Pro, so swapping modem firmware from another device isn't happening. I wonder if anyone with the Global variant has tried though.

I have Note 8 pro Global Version and band 7,20 is enable by default.

may work

Support for Carrier Aggregation LTE-Advanced(4G+)/LTE-Advanced-Pro(4.5G)?

Hello guys, I imported the device in the global version and read on some topic that it does
not support carrier aggregation LTE-Advanced(4G+)/LTE-Advanced-Pro(4.5G) anyone else to confirm this?

I confirm . Same problem whit vodafone italy , no carrier aggregation whit x2 but no problem whit x2 pro

Strange that they have limited this on the phone their version is the global one right?
Maybe if we press Realme he will release Carrier Aggregation, do you have the link of the email or forum?

yes, global model with b20, even I could not believe it, probably lte + is not essential but I still cannot understand how it is possible that it is absent in a medium-high end device in 2020. I'm also looking for a forum or an email to ask for explanations.

Apparently a large part of these medium-high Chinese smartphones have support for Carrier Aggregation blocked I saw in some post how to unlock the MI9 Chinese version and other phones
may work on Realme X2, however when I get mine I'll do the tests and try to unlock although I think it hardly reaches those speeds in my country and data plan,
well at least there is the B28 band that is not much like that price segment

Hello Sir almost everyone is facing this issue. For more info,I would suggest you to join the official telegram group @realmeX2Official , where you can connect with other x2 users and get instant solution for doubts and problems. Also we're working on custom roms. So join to get instant updates.

Oppo RealMe X2 support only Contiguous CA: https://cacombos.com/device?model=RMX1993EX - So this is reason why you don't get LTEA working in your network because your network do Non-Contiguous CA.

https://cacombos.com/device/SM-G986W Because your device doesn't support Carrier Aggregation combinations between 3, 5 and 40. You can check that easily on linked website.

Both model support CA but different combinations. Canada model is optimized to Canadian networks and Global to Global networks like India, Europe, Australia, Middle East... Just different models are targeted to different market area.
