Hi there! Sorry to hear you’re having trouble making calls to Germany with the Rebtel app. To help you better, could you share a bit more about what exactly happens when you try? For example, does the call not connect at all, does it ring but you get no answer, or do you see an error message?

Meanwhile, I can guide you through some initial steps to get started:

1. Check your internet connection: Calls made using Rebtel rely heavily on a stable internet or mobile data connection. Try switching between Wi-Fi and mobile data to see if that helps.

2. Update the Rebtel app: Sometimes call failures happen because the app isn’t communicating properly with Rebtel’s system. Make sure you have the latest version of the app installed.

3. Restart your computer: A simple reboot can refresh network settings and solve underlying temporary issues.

4. Verify your account balance: Ensure you have sufficient credit to make international calls.

5. Check the phone number format: Include the correct country code (+49 for Germany) and the correct area code without leading zeros.

If after these steps you’re still unable to connect calls, please let me know any error messages you see or describe what happens when you place the call. That will help me pinpoint the issue further.

Are you currently connected via Wi-Fi or mobile data? And have you tried updating the app recently?
