NOT FOR OOS, If you do this on TMO OOS you will lose connectivity.

So Lineage and all other AOSP based ROMs does not enable dual SIM for kebabt due to the T-Mobile modem having a hissy fit. However, you can flash the US/Global modem, retain all your 5G goodness, and enable dual-SIM as follows:

  1. Download the Global modem: https://www.androidfilehost.com/?fid=2188818919693783632
  2. Download the dsds magisk module: https://www.androidfilehost.com/?fid=2188818919693783509
  3. Flash the Global modem:
    fastboot flash modem modem.img
  4. Install the dsds magisk module

Make sure you follow all instructions in the lineage installation https://wiki.lineageos.org/devices/kebab, that will be my first question if you have any issues.

As always, thanks @LuK1337 and LineageOS Team
