# What should I do if I see the error “This code is no longer valid”?

**When an eSIM cannot be added and the message "This code is no longer valid" appears, it usually means one of the following:**
* The eSIM has already been installed (most common)
* The QR code was scanned incorrectly
* Too many eSIMs are stored on your device
* A VPN is interfering with installation

**Step-by-Step Fix**
1. **Check for existing installation**
* Go to **Settings** > **General** > **About** > scroll to **ICCID**
* If you see a number and your Stippl eSIM is listed under **Cellular Plans**, it's already installed

 If it's installed, turn on the line and enable data roaming:
* Go to **Settings** > **Cellular** > tap the relevant eSIM > toggle **Turn On This Line** ON
* Still on the same eSIM, scroll down and toggle **Data Roaming** ON
* Go to **Settings** > **Cellular** > **Cellular Data** and select the relevant eSIM
* Restart your phone to (re)connect to the local network

2. **Disable any VPNs**
* VPNs can interrupt installation. Turn off any VPN apps before retrying.

3. **Clear unused eSIMs**
* iOS limits the number of stored eSIMs. Delete old ones:
    * Go to **Settings** > **Cellular** > tap the eSIM > **Remove Cellular Plan**

4. **Update your device**
* Make sure you're running the latest version of iOS.

5. **Try manual installation**
* In the Stippl app: **eSIM** > select your eSIM > **Installation Instructions** > **Get Started** > **Not working? Install eSIM manually** (below the "Install Now" button)
* Note down: **SM-DP+ Address, Activation Code, Optional Confirmation Code**
* On your iPhone: **Settings** > **Cellular** > **Add eSIM** > **Use QR Code** > **Enter Details Manually**
* Enter the values exactly as shown in the Stippl app
* Set it as the default line for **Data Only**

6. **Enable Data Roaming and set Stippl eSIM as Mobile Data line**
* Go to **Settings** > **Cellular** > tap your Stippl eSIM > toggle **Data Roaming** ON
* Go to **Settings** > **Cellular** > **Cellular Data** > select your Stippl eSIM
