Hot-swap sim card in EC200A

Installing and Using OpenWrt Network and Wireless Configuration

I am going to use hot-swap sim card feature for EC200A-EUAB.
I use “AT+QSIMDET=1,1” to enable this feature but it does not work.
Its circuit was checked and is ok.
Do you think there is any config for this in menucofig?

Unrelated to OpenWrt. Better to ask at Quectel forum.
