Here Is network solution for LE2101 Indian Model
I personally tested it on Le2101 with Vi Operator also Volte is working

Steps:

1.----> After Color OS Booted restart your device into fast boot again
2.-----> Than flash below attach modem file (Extracted from c.35 Oxygen OS 12.1 Indian Variant) Using Bellow Command
fastboot flash --slot=all mdm_oem_stanvbk mdm_oem_stanvbk.img
3.------> Than reboot your device and enjoy network services

Warning: - I am not responsible if anything goes wrong, I tested it on my device, and it works
Will try and update... Any fix for sensors ?

    How to Flash ColorOS on OnePlus 9R

    Warrning!: flash at your own risk, Im not responsible for any hardware damages.
    This method is for testing purposes, don't expect everything to work


    Prerequisites:

    • OnePlus 9R (Tried on CN Unit LE2100 DDR5)
    • OOS 12 on both slots a/b
    • Unlocked bootloader
    • ColorOS Build from OnePlus 8T
    • Payload Dumber
    • Attached Flash_All.bat script (Big Thanks to @HELLBOY017 for it)
    • a brain to follow everything properly :p
    1. If you're already running OOS 12, and updated with OTA more than once, you can skip a/b on both slots

    2. If still running OOS 11, then Flash OOS 12 .21 then update to .33 so you have OOS 12 on both slots
    OOS 12 .21 Here, OOS 12 .33
    Here (Use attached OPLocalUpdate to flash .33)

    3. Unlock bootloader and let system boot up and finish setup


    4. Download ColorOS 12 for OnePlus 8T
    OnePlus 8T ColorOS 12.1 C.29
    Link 1, Link 2, Link 3, Link 4 (Download from one of them)

    5. Dump payload.bin from ColorOS Zip with payload-dumper-go
    Drag and Drop Zip into payload-dumper-go.exe and let it finish, ROM will be inside extracted_* folder

    6. Copy Attached flash-all-COS-9R inside extracted_* folder

    7. Reboot your 9R into bootloader


    8. Run flash-all-COS-9R .bat and let it finish

    9. Let device reboot when everything is finished and wait for system to boot, if device didn't boot reboot into recovery and wipe data



    Final note: This guide is for advanced users, I won't spoon feed you every detail or remote into your PC to do everything
    Also dont use any other tool to flash payload like fastboot enhance, it will brick your device
