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
2. • 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
3. • 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
4. • Restart your iPhone, reconnect to Wi-Fi, then try the installation again from the Stippl app

4. Disable VPN
5. • Turn off any active VPN before retrying

5. Try manual installation
6. • 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
