Hello everyone,

I'm having some difficulty understanding how it works. From the looks of it, 
/sim_set_slot_callback() /is only setting the /active_card_slot/ information. 
Shouldn't the sim properties be refreshed after switching? The newly activated 
sim card properties (imei, imsi, etc) should be updated to the atom, but I just 
don't see how this happens in the code.


This feature is assumed to work by having the modem perform sim removal and sim 
insertion.  The old SIM in the current active slot is removed and the new SIM in 
the new active slot is inserted.


The above works similarly to any other SIM removal / SIM insertion procedure: 
post_sim/post_online atoms are removed, sim atom wipes out all state related to 
the currently inserted SIM and re-initializes the state once the new SIM is 
inserted.

Understanding set_active_card_slot of the SIM atom

Hello everyone,

I'm writing a softdriver for a non AT modem and we have a Dual Sim Single
Active use case. At the moment there is only one example from the atmodem
softdriver where this interface is being offered.

I'm having some difficulty understanding how it works. From the looks of
it, *sim_set_slot_callback() *is only setting the *active_card_slot*
information. Shouldn't the sim properties be refreshed after switching? The
newly activated sim card properties (imei, imsi, etc) should be updated to
the atom, but I just don't see how this happens in the code.

Could someone enlighten me? I could be missing something.

Thank you in advance for your help,
uaz
