How do TextNow users on Reddit typically resolve calling issues related to "an error has occurred"?

For calling errors, Reddit users usually focus on network quality. They recommend ensuring strong Wi-Fi or cellular data signal. Disabling Wi-Fi calling (if active) on your device, or conversely, trying a different Wi-Fi network. Also, checking microphone permissions for the TextNow app is critical. Sometimes, the issue is with the recipient's line, so trying another number can help diagnose. Rebooting the device and router are also standard first steps.
