TK103b won't respond to my phone calls or txt requests for it's location

Tom_Sam

Hi Guys,
I think my TK103 has a problem, when I call it or send SMS address123456 it ignores me.
All the other commands work, for example check123456 gives a list of the status of Power, Bat ETC,
Any ideas what it could be.
I’ve already done a reset123456 and a begin123456.

Hello Tom_Sam

Probably you activated a GPRS mode.
So, try sms123456 command to turn your device to SMS mode, then most likely your device will start to reply to this command.

Hi Mohamedbardala

Since your device responds to SMS but doesn’t send warning messages, this suggests there might be issues with the mobile data connection or server settings. Here are the recommended steps to troubleshoot:

Check the SIM card:

Verify the balance
Ensure the data traffic limit hasn’t been exceeded
Confirm mobile data is enabled

Verify the tracker settings:

Check the APN settings match your SIM card provider
Ensure the server IP and port are correctly configured
Confirm the time zone is set to 0 (UTC)
