### Hardware Required
To run this example, you need an ESP32 dev board (e.g. ESP32-WROVER Kit) or ESP32 core board (e.g. ESP32-DevKitC).
For test purpose, you also need a cellular modem module. Here we take the [SIM800L](https://www.simcom.com/product/SIM800.html) and [BG96](https://www.quectel.com/product/bg96.htm) as an example.

You can also try other modules as long as they embedded PPP protocol.
**Note:** Since SIM800L only support **2G** which will **not** work in some countries. And also keep in mind that in some other countries it will stop working soon (many remaining 2G networks will be switched off in the next 2-3 years). So you should **check with your local providers for further details** if you try this example with any 2G modules.

This example is similar to the [console example](../console/README.md), but instead of the UART it uses USB CDC for console output.

The example uses the [Console Component](https://docs.espressif.com/projects/esp-idf/en/latest/api-guides/console.html#console) to create an interactive shell.
The interactive shell implemented in this example contains a wide variety of commands, and can act as a basis for applications that require a command-line interface (CLI).
