If the output of the shell command 'service list' contains 'telephony.registry2', then the phone has a second SIM card. If contains 'telephony.registry3', then phone has a third SIM card and so on.
You can use this shell command to send from the first SIM card:
service call isms 5 s16 "PhoneNumber" i32 0 i32 0 s16 "BodyText"
and from the second SIM card
service call isms2 5 s16 "PhoneNumber" i32 0 i32 0 s16 "BodyText"
Require android.permission.SEND_SMS
