Question

Electronics

The task is to connect 2 sim cards to one GSM module. What are the ways to realize this miracle? multiplexers, switches, etc. It's
good if there are circuits

Answer 1

I'd rather post it on the appropriate forum.

Answer 2

The options are different - you can send one of the sims to an eternal reset, you can switch CLOCK from one card to another, you can supply power to only one of the cards.
Please note that only one card will work at a time, and switching will take tens of seconds.
