Hello everyone.

I have a RBM33G with an LTE modem and a single SIM adapter M.2 to miniPCI. I want to change it to a dual SIM adapter, like this -> https://aliexpress.com/item/1005001768067596.html
Anyone tested this solution?

I checked on my RBM33G with a single SIM adapter the SIM change commands mentioned in this topic viewtopic.php?t=159520 but they are not available.

I will answer myself

I got the question wrong due to lack of knowledge. The SIM sockets are switched by the modem itself, if it supports it. So just use AT commands.

For example, the AT command to change the SIM in the quectel em12-g modem
