Hello Peter,
Thank you for your question.
To get an SMS message of the event (if the button is pressed), firstly, you will need to go to the Teltonika Configurator -> GSM -> SMS Events Numbers and set phone number which will be used to get events. When you will set, then you will need to go to the Teltonika Configurator -> GSM -> SMS Events and set:
- AVL ID of DIN, on which is using SOS button;
- One of the phone numbers which you added on SMS Events Numbers;
- Text of the event, which you will get to the chosen phone number.
After changes, do not forget to save them to the unit.
Full description about this setting you will find here: https://wiki.teltonika-gps.com/view/FM6300_SMS_Events
Please let us know if you will have more questions.
Best Regards,
Teltonika Support
