Hello AKCP Support,

I have a problem where I can’t send an alert via SMS consistently. Sometimes AKCP returns an message “invalid SMS error 512”. I have tried rebooting the main unit, reconnecting the modem, and clearing logs. And the error message still appearing, can you help me identify what could be the problem?

Thank you.

Dear AKCP Customer,

Normally the error messages are received from the service provider.

We suggest you check the following;
Test your SIM card in your mobile phone to ensure it is working properly and also has good signal strength where the unit is located.
Try using a different SIM card from another service provider.
Upgrade the firmware to the latest on our website support portal.

Also, it sounds like you are using an external modem. If so, we no longer support external modems on the securityProbe units. It could very well be a problem with the modem.

Please contact [email protected] for possible options on upgrading to our AKCP internal modem.

Thanks you,

Best regards,
AKCP Support Team
