Sending an SMS will happen in 1-10 seconds of the trigger. In case
the SIM subscription does not support sending SMS, the messages
will not be sent.
Once the SMS has been sent by the Lock 500, the time to get it
delivered to the destination is dependent on the Operator used.
Some subscriptions need the Message Service Center number
defined to be able to send SMS messages. This can be set in
“Internal Modem “ settings where ”SMS center number” can be
defined. The number should be defined in international format (e.g.
“+358…”
Note that the setting can be defined separately for both SIM slots.
