au系のsimとdocomo系のsimの2枚使用していますが、どちらをsim1にしてもsim2が認識しません。
#06#で確認したところimeiが1つしか表示されません。
sim2側はどうすれば有効になるでしょうか？

システムアップデートでデュアルsim有効になりました。出荷時のファームウェアでは未対応のようです。
Thank you user10195801 for posting the answer; this is very helpful for me. let me translate it for other users' ease of reference.
user10195801 asked:
I use two au sims and two docomo sims, but sim2 does not recognize either sim1.
#06 I checked in #, I only see one imei.
How does the sim2 side work?
user10195801 clarified:
Dual sim enabled in system update. The factory firmware does not support it.

There are 4 system updates by mid Feb 2021. The dual sim support came after the 3rd updates.
However, there are still problem with the phone not being able to recognised sms that's saved separately under sim 1 and sim 2 from my old HTC phone.
