Hi. After one year or perfect working, the tracker stopped recieving and sending SMS.
The GSM signal is normal. When I call the device it rings 2 time, then it hangs up, but I recieve no SMS …

SpardaDante Hello!
Sending messages is not related to the application.
You can try to find out first whether the SIM card or tracker chip is all right. Perhaps there are exceeded some limits for sending messages (this sometimes happens).
If this is all right, try restarting the tracker and setting it up again if necessary.

ashe I already tried the SIM Card and find no problem. I was wondering if the problem is comming from the Tracker being expired after a periode of time.
I tried to change the original Tracking Server (GPS110.org) with GPS-Trace one, and the tracker is not recieving SMS.
But when I call the device, there is a ringtone so the SIM card is not the problem
Is it possible that after a year of usage, the manufacturer blocked the device ?

SpardaDante Hello!
In this case, it is best for you to try to contact the seller or manufacturer. Or maybe you should contact the service center, especially if you do not want to restart the tracker, because you think that you can’t configure it later.
There they will be able to tell you why similar problems may arise precisely with your tracker, since trackers of different manufacturers function differently.

Usually this SMS problem is the telephone company that blocks the use of the normal chip for use in trackers, you have to buy an M2M chip.
