# What to do if I see "Unable to Activate eSIM"?

The "Unable to Activate eSIM" error usually occurs when iOS cannot complete the eSIM provisioning process.

###### Common causes:
* Poor or unstable internet connection during installation
* The eSIM has already been installed or used
* Your device is not connected to Wi-Fi

###### What to do:

1. **Check your Wi-Fi connection**
    * Make sure you have a stable Wi-Fi connection — do not try to install over cellular
    * If your Wi-Fi is unstable, try a different network

2. **Check if the eSIM is already installed**
    * Go to **Settings** > **Cellular** — if you see a **Secondary** line, your eSIM was installed successfully
    * Follow the steps in "How to access the internet using your eSIM?" to configure it

3. **Restart and retry**
    * Restart your iPhone, reconnect to Wi-Fi, then try the installation again from the Stippl app

4. **Disable VPN**
    * Turn off any active VPN before retrying

5. **Try manual installation**
    * In the Stippl app: **eSIM** > your eSIM > **Installation instructions** > **Get started** > **Not working? Install eSIM manually**
    * Follow the manual entry steps using your SM-DP+ Address and Activation Code
