# Smartphone cURL Test

> Test the proxy connection using cURL commands on a mobile device.

For this test, we suggest **Termux**, which is a powerful terminal emulator that provides a full Linux environment on mobile devices. It allows running the `cURL` command-line directly from a mobile device. Termux is supported on Android and iOS devices and enables advanced networking tasks typically performed on desktop systems.

## Why is `cURL` useful?

`cURL` is a command-line tool used to send requests. It is commonly used to verify proxy connectivity and test network responses. When used with proxies, it routes traffic through a specified IP address, which helps test different geographic locations and diagnose connectivity issues. It also returns clear response codes and IP information for troubleshooting and verification purposes. A successful proxy connection accompanied by valid IP response data indicates that the proxy is operational.

## Termux Setup

**Step 1.** Download Termux from the [**Play Store**](https://play.google.com/store/apps/details?id=com.termux\&hl=en_GB) (Android) or [**App Store**](https://apps.apple.com/us/app/termux/id6738933789) (iOS) on your device.

**Step 2.** Open the application and enter: `pkg install curl`.

**Step 3.** Tap **new line** on your keyboard.

**Step 4.** Enter the `cURL` command using your own proxy credentials:

<CodeGroup>
  ```shellscript cURL theme={null}
  curl -U 'USERNAME:PASSWORD' -x gate.decodo.com:7000 https://ip.decodo.com/
  ```
</CodeGroup>

<Note>
  * Don't forget to use the endpoint and port corresponding to the specific proxy type you are using.
  * Learn how to find **proxy details** in your dashboard for each proxy type [**here**](https://help.decodo.com/docs/proxy-quick-start-guides).
</Note>

**Step 5.** Tap **new line** on your keyboard.
