# Troubleshooting Wallet Linking ### Troubleshooting Wallet Linking If you're having trouble adding your PayProtocol Card to a mobile wallet (Apple/Google/Samsung Pay), try the following solutions: *** #### 🔧 Common Fixes * Ensure your device’s **region and language** match the wallet service. * Make sure your PayProtocol **Card is active** and not frozen. * Restart your phone and try again. * Update both the wallet app and the PayProtocol app. *** **🔐 Security Verification** * During online purchases, you may need to provide a **one-time password (OTP)** sent to your registered email (3D Secure verification). * If your card was blocked due to suspicious activity, you'll need to unblock it through the app. * Note that block/unblock actions may lock further status changes for 24 hours. *** #### 📞 Still Not Working? * Contact customer support through the PayProtocol app. * Provide: * Phone model and OS version * Screenshot of the error * Your card’s last 4 digits (never share full number) *** > 🛡️ Linking usually takes just a few seconds — persistent issues can often be fixed by reinstalling or updating apps. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
