Page 9: Connect Power Source
Send 2 SMS messages to the inserted SIM card number to configure APN username and password (optional for some GSM providers – default username and password are empty): #pass,gprsuser=APN_USERNAME #pass,gprspass=APN_PASSWORD Example: #pass,gprsuser=guest #pass,gprspass=guest The module will reply with the following response: APN username saved APN password saved User Manual (1.4.0) OpenTracker 2.4... -
Page 10: Change Sms Password
Please allow some time for the device to reboot after the last SMS reply. Do not immediately turn it off. Register To use the Geolink web interface (www.geolink.io) you need to register your OpenTracker device. Please follow this guide: https://geolink.io/guide.php Make sure your device is configured, powered and ignition is on, so that it connects to the tracking server. -
