network and internet

The device will need to act as the client as almost all mobile network providers block incoming connections.

You will also need to:
1. Know your computer ip address.
2. Configure the router to forward the port communication to this specific computer.
3. Open the port in your computer firewall.

But I use my device only to receive data from the PC.
then the mobile network is not possible, right?

You can receive data from the PC. The point is that the device must make the connection.
