Second sim not active issue

Hello, I just got myself the xiaomi mi 9 from vodafone uk and it seems they disabled the second sim. Any way I can activate it , before I try and sell the device? Would flashing something like xiaomi eu solve the problem?

There's something wrong, as the Xiaomi doesn't have a "carrier rom" anywhere in the world.
Describe the problem more, the tests made, the rom version, etc.

Vodafone Uk is seling the xiaomi mi 9 6gb ram/128 gb. On the box it says it is a single sim phone and in the manual it says that the second sim is inactive. I'm asking if it is possible to install a different rom or firmware version that allows the second sim to be used, considering the tray has two slots.

Well I doubt they hardware crippled it.
So I say yes, try ROS or Xiaomi.eu.

I'm quite confident you can. If you want to keep the MIUI style you can go for xiaomi.eu ROMS etc.
Be aware that once you buy the phone, you will have to request Xiaomi your bootloader unlock code, and sometimes they make you wait up to 2 weeks. And without an unlocked bootloader, you can't flash other roms.

Global ROM with locked Bootloader on Chinese Varient k20 pro

Hi Android Enthusiastic's
I was totally impressed by Redmi k20 pro specs and price and I had brought it from China next day it was released in Chinese market, I had to deal with slot of Chinese bloatware and I was finally waiting for official global ROM to released and I unlocked bootloader and flashed global ROM and when I try to relock the bootloader it gets stuck in recovery mode
And works fine with unlocked bootloader
And later I came to know that Xiaomi had actually did this on purpose that no should do like this
I ask all you is there any workaround for this that I can have official global rom and locked Bootloader
Because unlocked bootloader can lead to hacking and loss of sensitive information and potential for virus attack

Since you have the chinese variant if the phone locking it's bootloader will limit the phone to ONLY being able to boot the Chinese ROM or one of these fake global ShopROMs which nobody should use (in my opinion).
I don't think it possible to flash the official global ROM and lock the bootloader. Maybe some day the Pro's will be able to convert a Redmi K20pro to a Mi 9T Pro with baseband and bootlock support but at the time of writing this is not possible.
Until then you have to choose between Chinese ROM with locked bootloader or any other ROM with unlocked one. I use Xiaomi.eu ROM with unlocked Bootloader and deem the data encryption safe enough.
A thief could boot TWRP, format data and have my phone but that is a risk I can take. In that case I might even still be able to lock the phone with my mi account if the thief used MIUI

Xiaomi Mi 9 not detecting sim cards

Hey guys,
I have recently unlocked my bootloader and flashed xiaomi eu rom, the problem is that the phone does not detect my sim cards in the phone. Bearing in mind i purchased this phone from vodafone on contract so i don't know if that has something to do with this.

I have a similar problem, did you get it resolved ?

hi,
i just bought a Redmi 10x 4g,from Ali express when i bought it i didn't notice that in the description it was written Global rom instead of global version ,
