A. 1. Check your network signal: Ensure you have a strong signal for calls. If you are in a low-signal area, try moving to a location with better reception. 2. Restart your device: Sometimes, a simple restart can resolve connectivity issues. 3. Update the app: Ensure you have the latest version of textPlus by checking the Google Play Store for updates.

B. 4. Test with other apps: Try making calls using other apps (like WhatsApp or Skype) to see if the issue is specific to textPlus or your network.
