FMC130: 131072 Received & 128 Sent SMS ! - HACKED?

For a few months now I have seen a very high number of incoming and outgoing SMS on my FMC130 Device. But my IoT provider says no SMS was sent to the SIM card …? I have been using the tracker for 3 years and so far at Received and Sent has always been 0. But now a very high number?

When I reset, a very high number will appear after a few days, and there are exactly 128 SMS SENT again?

But SMS is NOT configured:

SMS vom 2025-02-23 19-27-33
SMS vom 2025-02-23 19-27-33729×548 19.8 KB

Was I hacked by a secret service or what is it all about?

Can you generally switch off SMS reception and send?!

i no longer trust this matter and think about expanding the tracker :frowning:

I Use Teltonika.Configurator 1.7.30 B3.27_R.29 and Firmware 03.29.00 Rev: 18.

Thank you for your help !!

Hi @Telematics2000

Good day, to make sure that no one can hack your device, make sure that you configure the device SMS commands and Authorized Numbers settings.

SMS commands - make sure that you have configured the login and password to avoid any unwanted SMS.
Authorized Numbers - Make sure to add authorized numbers so that the device will only accept commands from the number registered on the device.

If the issue still persist please contact your sales manager for the proper support.

Best Regards
