How could anyone have tested this? As changing SIM always had the need for swapping battery!
In general I do not see why it should not work, as also those adapters do nothing else than switching circuit form one SiM to the other (but okay maybe some power on initialising going on?). If you like to try do a simple Code: killall csd This will cleanup (a bit unnicely but as first shot), then we can have a look at phonet-helper script ...
killall csd
