Hi max_jens3n,
Thank you for reaching out. I understand how inconvenient it can be to have issues with sending texts. Let’s try some additional steps to resolve this problem:
Update iOS and Apps:
Although you mentioned your iPhone is on the latest iOS version, ensure all your apps are also updated. Go to App Store > Your Profile > Updates and make sure there are no pending updates.
Check Date & Time Settings:
Incorrect date and time settings can sometimes cause messaging issues. Go to Settings > General > Date & Time and make sure "Set Automatically" is turned on.
Sign Out and Sign Back In to iMessage:
Go to Settings > Messages > Send & Receive. Tap your Apple ID at the top, then tap "Sign Out". After a few moments, sign back in using your Apple ID.
Clear Message History:
If there is a large volume of message history, it might affect performance. Consider deleting old conversations. Go to Settings > Messages > Keep Messages and select a shorter duration if applicable.
Check for Restrictions:
Ensure there are no restrictions that might affect messages. Go to Settings > Screen Time > Content & Privacy Restrictions and check if there are any restrictions that might be impacting your messaging.
Inspect for Physical Issues:
Though less common, physical issues or damage to the phone might impact its functionality. Inspect your phone for any visible damage or unusual behavior.
Restore iPhone from Backup:
If none of the above steps work, consider restoring your iPhone from a backup. Before doing this, make sure to back up your data. You can restore your iPhone by connecting it to a computer, opening Finder (on macOS Catalina or later) or iTunes (on earlier macOS or Windows), and selecting "Restore Backup."
Factory Reset (As a Last Resort):
If the problem persists, a factory reset might be necessary. Make sure to back up your iPhone before doing this. Go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings. Follow the on-screen instructions to complete the reset.
Visit an Apple Store or Authorized Service Provider:
If you’ve tried all the above steps and the issue still persists, there may be a hardware issue or a more complex problem that needs professional attention. You can make a Genius Bar appointment at an Apple Store or visit an authorized service provider.
Please let me know if any of these steps help or if you need further assistance. I'm here to help!
