HONOR 400

Some Honor models support eSIM.
To check compatibility directly on your phone, act as if you’re making a call, dial *#06#, and see if an EID field appears.
Otherwise, go to Settings > About phone > EID.

If you see an EID field, then your phone supports eSIM!

For Dual SIM models, the SIM 2 slot can be configured as either an eSIM or a nano SIM card. For single-SIM models, the SIM 2 slot only supports eSIM.
