How to Solve MOBITEK S150 Rebooting Every 1 Minute

PROBLEM SOLUTION
Find out why S150 keeps rebooting every 1 minute.

 

The problem will occur when S150 is unable to reply by SMS to the “1234CC” and “1234DD” commands.

In our case, the cause is SMS quota in the Yoodo SIM card has been exchausted, so S150 is not able to reply via SMS to any command send to it. When it failed to send out SMS, it would self-reboot. This will be repeated for every 1 minute until SMS is successfully send out.

Solution: Keep the credit balance available all the time to avoid the S150 rebooting every 1 minute in order to resend SMS.
