Hi all. Happy new year to you all.

I need help, I got gifted my first device on new year a Xiaomi 13 pro 5G which my mum bought fro Aliexpress

Here is the problem, I inserted my sim, it recognises my sim but says no service. I can only use wifi and can't make calls or use mobile date cos no service.

I've spent the whole day online and see some threads here that it's possible to fix by installing a program file called modem. I want to know if this method can work in my device. Below are my phone details.

Xiaomi 13 pro 12/512 5G

Model number on phone pack (2312CRAD3C) I've learnt this is chinese version.

Inside phone specs shows it's running Xiaomo Hyper OS version 1.0.7.0.UNRIDXM and model number when inside about of phone is (2312DRA50G)

I got to developer option and it shows Mi Device is locked and safe (bootloader locked)

Please help me and answer what I can do to get sim card service.

Also is it possible to manually upgrade my hyper OS even tho the bootloader is locked)

Also with lock bootloader can I go back to official chinese rom as I understand this is a global rom replaced the rom inbuilt?

Help me please. Sorry for too much text. Just tried to be comprehensive.

Thanks in advance.
