The error message says sorry message couldn’t be delivered

Thank you for clarifying that you're receiving an error message stating, "Sorry, message couldn’t be delivered." Let's try to resolve this issue step by step.

1. Check Network Connection:
- Ensure your iPhone is connected to a reliable internet connection, either through Wi-Fi or cellular data.
- You might try toggling Airplane mode on and off to reset the connection.

2. Update the AT&T Office@Hand App:
- Make sure your Office@Hand app is up to date. Open the App Store, go to the "Updates" tab, and see if there's an update available for the application.

3. Restart Your iPhone:
- Sometimes a simple restart can fix issues. Hold down the power button and slide to power off, then turn it back on.

4. Check Message Settings:
- Go to your Settings app, scroll down and tap on "Messages." Ensure that your SMS and MMS settings are enabled if you are trying to send regular texts.

5. Reinstall the App:
- If the above steps don’t work, try deleting the AT&T Office@Hand app and reinstalling it from the App Store. This can help if there are any issues within the app itself.

6. Verify Your Account Status:
- Sometimes, bills or account issues could affect your message sending capabilities. Log into your AT&T account online to check if there are any notices or outstanding issues.

Can’t send outgoing texts

Thanks for your patience! Since you're still having issues with sending outgoing texts through the AT&T Office@Hand app, let's explore a few more detailed steps to troubleshoot this situation for you.

1. Double-check Your Message Settings:
- Make sure that the "Send as SMS" option is enabled on your iPhone. Go to Settings > Messages and toggle on "Send as SMS." This way, if the internet isn't available, your texts will still go through as SMS.

2. Check Your App Permissions:
- Sometimes, app permissions can affect functionality. Go to Settings > AT&T Office@Hand and ensure that it has the necessary permissions to send messages.

3. Log Out and Back In:
- Open the Office@Hand app and log out of your account, then log back in. This can refresh your connection with the app and its servers.

4. Clear App Cache:
- If there's an option in the app settings to clear the cache or data, go ahead and do that. It can help if there’s any corrupt data affecting performance.

5. Contact AT&T Support:
- If you've tried all the above and still can't send texts, it may be worth contacting AT&T support directly. They can check if there are any account-related issues or outages affecting text messaging for your number.
