iPhone XS Not Sending SMS After iOS 12.1.4 Update? Here’s How to Fix It

If your iPhone XS suddenly won’t send SMS messages after updating to iOS 12.1.4, you’re not alone. It’s a common post-update issue that can stem from network glitches, outdated settings, or even SIM problems. Here’s how to troubleshoot and get your texting back on track.

1. Force Close the Messaging App

The Messages app may have glitched during the update. Restart it:

Swipe up from the bottom of the screen and pause in the middle.
Swipe up on the Messages app to close it.
Open Messages again and try sending a text.

2. Restart Your iPhone

A simple soft reset can clear out any temporary bugs:

Hold Side button + Volume Up or Down.
Slide to power off.
Wait 30 seconds, then turn your phone back on.

3. Turn iCloud Messages Off and On

Sometimes syncing issues with iCloud Messages can interfere with basic SMS:

Go to Settings > [Your Name] > iCloud > Messages.
Turn Messages OFF, wait a few seconds, then turn it back ON.
Reboot your iPhone and try sending an SMS again.

4. Toggle Airplane Mode

Refreshing your phone’s network connections can do wonders:

Go to Settings > Airplane Mode and turn it ON.
Wait 10 seconds, then turn it OFF.
Wait for your phone to reconnect to the cellular network, then send a test SMS.

5. Reset Network Settings

Corrupt or conflicting network settings can cause SMS issues:

Go to Settings > General > Transfer or Reset iPhone > Reset.
Tap Reset Network Settings.
Reconnect to your Wi-Fi if needed, then test SMS functionality.

6. Remove and Reinsert the SIM Card

Physical SIM issues can also block texting:

Turn off your iPhone.
Use a SIM ejector tool to remove the SIM tray.
Take out the SIM, inspect it for damage.
Reinsert the SIM and turn the iPhone back on.

7. Factory Reset (If All Else Fails)

Back up your data first via iCloud or iTunes.

Go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings.
Follow the prompts to wipe your device and start fresh.
After setup, try sending SMS again.

Bonus Tips for Third-Party Messaging Apps

If you’re using apps like WhatsApp or Signal and they’re not working:

Go to the App Store > Updates tab.
Tap Update next to your messaging app.
If the issue persists, delete and reinstall the app.

Still Can’t Send SMS?

Call your carrier to check for account issues or outages.
