Hello Raul,
Thank you for your question.
In this case, we would like to recommend to check some requirements:
1. Check the status window of the configurator.
Start the configurator and connect to the device to the computer via USB or via Bluetooth. Once in the configurator, you will be defaulted to the Status window, when the parameters load, select GSM info tab and check whether the device reads the SIM card properly
2. SIM card or GPRS has not been activated
Insert your SIM card into the mobile phone to make sure you can make/receive calls, send/receive SMS, check if you can browse the Internet. SIM card insertion instructions for each device can be found in the "First Start" section of the appropriate device. E.g. https://wiki.teltonika.lt/view/FMU130_First_Start
3. PIN code request is enabled on SIM card
It’s recommended to disable PIN code requests before inserting SIM card into the device
4. The device has no GSM signal
There is no GSM network coverage in the area.
Make a call to the device to make sure that the device connected to the GSM network. You should hear a normal calling tone.
5. Incorrect external power source
For proper functioning of the unit, it must be connected 10-30V DC power supply
Please let us know if they were helpful.
Best Regards,
Teltonika Support
