• Check your Wifi Calling settings
  • If you are on good cellular PSTN coverage and Wifi Calling turned on, go to Settings > Call Settings > Wifi Calling and tap the toggle off. This will allow Grasshopper to only use your cellular PSTN data to take calls.
  • If you are in an area with poor cellular PSTN coverage but good local WiFi Internet, go to Settings > Call Settings > Wifi Calling and tap the toggle on to use wifi for calls.
• Try restarting your mobile device.
• If you are still experiencing call quality issues after going through the options mentioned above, uninstall and reinstall the Grasshopper mobile app.

The Grasshopper desktop app uses your internet connection to take and receive calls so verify you have a good connection first.

• Close out any unnecessary applications that are running while you are using the app and check your CPU usage by opening the Task Manage (PC) or Activity Monitor (Mac).
• Switch to another available network (if available)
• If you are using wifi, switch to using an Ethernet cable.
• Try restarting your computer.
• If you are still experiencing call quality issues after going through the options mentioned above, uninstall and reinstall the Grasshopper desktop app.

In addition you can do the following tests to check or improve your internet connection:

• Navigate to speedtest.net and run a test to check your upload and download speed.
• Restart your router. Often, a hard reset can be performed by unplugging the router and then waiting 30 seconds before plugging it back in.
