To ensure smooth functioning of the CallHippo app on iPhone, please check the following before beginning any troubleshooting:
Do not use a VPN – VPNs may disrupt call connectivity and app performance.
Disable Low Power Mode – This restricts background activity and may prevent the app from receiving calls or notifications.
Update the CallHippo app – Install the latest version from the App Store.
Keep your iOS version up to date – An Outdated iOS may cause compatibility issues.
Allow all permissions – Especially microphone, notifications, and background app refresh.
If issues still persist, follow the specific instructions below based on the problem you're facing.
1. Login Issues
If you're unable to log in to the CallHippo app:
Make sure you’re using the correct email and password
If needed, tap Forgot Password and follow the reset instructions sent to your email
After resetting, fully close and reopen the app
Ensure that you're connected to a stable network (Wi-Fi or mobile data)
If Face ID or Touch ID is enabled for login, make sure biometric permissions are active in device settings
Still facing issues? Uninstall and reinstall the app from the App Store
2. Outgoing Call Issues
If outgoing calls aren't going through or are dropping:
Go to Settings > CallHippo > Microphone, and make sure it’s enabled
Open the app and enter the number with the correct country code (e.g., +44 or +1)
Switch between Wi-Fi and mobile data to test for network issues
Ensure you're not using a VPN or firewall
If you’re using AirPods or Bluetooth, check that the audio is not being routed incorrectly
Restart your iPhone and try again
Check the App Store for updates to CallHippo, and install if available
3. Incoming Call Issues
If incoming calls aren’t ringing or are delayed:
Go to Settings > Notifications > CallHippo, and ensure Allow Notifications is turned on
Enable Sounds, Banners, and Lock Screen notifications
Go to Settings > CallHippo, and enable Background App Refresh
Disable Low Power Mode: Settings > Battery > toggle off
-
Make sure Focus mode (Do Not Disturb) is not active:
Open Control Center > check if Focus is on → Turn it off
Or go to Settings > Focus > Do Not Disturb and remove CallHippo from blocked apps
Allow CallHippo under Settings > Cellular if restricted
Restart your device and open the app to ensure it stays active in the background
4. App Crashing or Freezing
If the app crashes at launch or during calls:
Force close the app by swiping up from the App Switcher
Open Settings > General > iPhone Storage > CallHippo, and offload the app, then reinstall
Check for any pending app or iOS updates
Restart your iPhone to clear background processes
If storage is low, free up space and then try again
If the problem continues, uninstall and reinstall the app
5. Auto-Logout or Session Timeout
If the app logs you out automatically:
-
Make sure you're not logged in on another iOS or Android device using the same account
CallHippo accounts should only be active on one device at a time
Go to Settings > CallHippo, and ensure Background App Refresh is enabled
Disable Low Power Mode, as it may cause the app to be suspended in the background
Restart your iPhone to refresh system memory
Make sure app updates are installed from the App Store
6. Final Troubleshooting Checklist
If issues are still unresolved, check the following:
Restart your iPhone
Ensure microphone access, notifications, and background app refresh are all enabled for CallHippo
Disable VPN, firewall apps, or any privacy features that may block VoIP traffic
Confirm you are not using Screen Time restrictions or App Limits that affect CallHippo
Switch from Wi-Fi to mobile data or vice versa to rule out connection problems
Avoid force-closing the app regularly—it may affect background services
Reinstall the CallHippo iOS application from the App Store
