iOS (iPhone)
For users on iOS 18 or later, built-in app settings have moved to a dedicated section.
- Enable SMS Fallback:
- Go to Settings > scroll to the bottom and tap Apps ≫ Messages.
- Scroll down and ensure Send as SMS (or Retry as Text Message) is turned ON.
Note: This allows your phone to send messages as regular text when iMessage is unavailable, ensuring communication with non-iOS devices.
- Verify iMessage Settings:
- In the same Messages menu, ensure the iMessage toggle is ON.
- Tap Send & Receive. Ensure your phone number is selected under the "You can receive iMessages to and reply from" section.
- Check Blocked Contacts:
- Go to Settings ≫ Apps ≫ Messages ≫ Blocked Contacts.
- Verify the list does not contain the contact you are trying to reach.
- Reset Network Settings:
- If the issue persists, reset your network connectivity (this will delete saved Wi-Fi passwords).
- Go to Settings ≫ General ≫ Transfer or Reset iPhone ≫ Reset ≫ Reset Network Settings.
- The device will reboot. Test the service again.
Android
Most modern Android devices use RCS (Rich Communication Services), which requires an internet connection.
- Check RCS/Chat Settings:
- Open the Messages app (ensure it is the default app, not a third-party one).
- Tap your Profile Picture/Icon in the top right > Messages settings.
- Tap RCS chats (on older versions, this may be labeled Chat features).
- Toggle the feature OFF and test your service. If it works, try toggling it back ON, wait for the "Connected" status, and test again.
- Unblock Contacts:
- Tap your Profile Picture/Icon ≫ Messages settings ≫ Spam & blocked.
- Select the contact from the list and tap Unblock.
- Reset Network Settings:
- Go to Settings ≫ System ≫ Reset options.
