iMessage Stuck on Sending? Fixes That Work

If your iMessage is stuck on “Sending…” or shows “Not Delivered,” the fix usually involves checking your network connection, restarting the Messages app, or toggling iMessage off and on. Below are the most effective troubleshooting steps, from quick checks to deeper resets, along with explanations of why each one works.

Why iMessage Gets Stuck on Sending

iMessage relies on Apple’s servers to route your message as data, not as a standard SMS. When the blue bubble won’t send, it means your device can’t reach Apple’s servers or the recipient’s device isn’t confirming delivery. Common causes include:

• Weak or unstable Wi-Fi or cellular data
• Apple’s iMessage service being temporarily down
• Incorrect date and time settings on your iPhone
• Outdated iOS or carrier settings
• A software glitch in the Messages app
• The recipient has iMessage disabled or is out of coverage

Quick Checks Before You Reset Anything

Start with the simplest possibilities. Open Control Center and verify you have a Wi-Fi or cellular connection—if you see “No Service” or a weak signal, move to a different spot or toggle Airplane Mode on and off. Also check if the issue affects only one contact or all contacts. If it’s just one person, they may have turned off iMessage or switched to an Android phone, and your message will eventually send as a green SMS if you have “Send as SMS” enabled in Settings.

Another quick check: try sending a message to yourself. If that works, the problem is likely with the recipient’s device, not yours. If it also fails, continue with the steps below.

Force-Quit and Restart the Messages App

A temporary glitch in the Messages app can freeze the sending process. To force-quit:

1. Swipe up from the bottom of the screen (or double-click the Home button on older models) to open the App Switcher.
2. Swipe up on the Messages card to close it.
3. Wait a few seconds, then reopen Messages and try sending again.

If that doesn’t help, restart your iPhone. This clears the system’s temporary memory and often resolves stuck network connections. Press and hold the side button and either volume button until the power off slider appears, then slide to turn off. Wait 30 seconds, then turn it back on.

Toggle iMessage Off and On

Turning iMessage off and back on forces your device to re-register with Apple’s servers, which can clear a stuck activation or authentication state. Go to Settings > Messages, turn off iMessage, wait about 30 seconds, then turn it back on. You may see a brief “Activating…” message—wait until it says “iMessage” is on again. This is one of the most reliable fixes for a single stuck message.

If toggling doesn’t work, also try toggling Send as SMS off and on. This ensures that if iMessage fails, your message will fall back to a regular text, which uses a different network path and often goes through when iMessage is blocked.

Check Apple’s System Status and Your Date/Time

Sometimes the problem isn’t on your end. Apple has a public System Status page that shows whether iMessage is currently experiencing an outage. If the service is listed as “Issue,” you’ll need to wait until Apple resolves it—no amount of troubleshooting on your phone will help.

Incorrect date and time settings can also break the encryption handshake that iMessage uses. Go to Settings > General > Date & Time and make sure Set Automatically is turned on. If it’s already on, turn it off, wait a few seconds, then turn it back on to force a refresh.

Update iOS and Carrier Settings

Apple regularly releases iOS updates that fix bugs, including issues with iMessage delivery. Go to Settings > General > Software Update and install any pending update. Similarly, carrier settings updates can improve network compatibility—these appear as a pop-up when you connect to a new network, but you can also check manually by going to Settings > General > About and waiting a few seconds for a “Carrier Settings Update” prompt.

Outdated software can cause protocol mismatches, so keeping both iOS and carrier settings current is a solid preventive measure.

Reset Network Settings (Last Resort)

If none of the above works, resetting your network settings can clear corrupted Wi-Fi, cellular, and VPN configurations. Note that this will erase saved Wi-Fi passwords and Bluetooth pairings, so you’ll need to re-enter them. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. Your iPhone will restart, and you’ll need to reconnect to Wi-Fi. After that, try sending your iMessage again.

This is a more aggressive step, so only do it if the simpler fixes fail. It does not delete any of your personal data, messages, or photos.

Frequently Asked Questions

Why does my iMessage say “Not Delivered” but my friend received it?

This can happen when the recipient’s device sends a delivery confirmation but your phone doesn’t process it correctly, or when the message was sent as an SMS fallback. Check if the message shows as “Delivered” under it after a few minutes—if it does, the error was temporary. You can also ask the recipient if they got it.

Will turning off iMessage delete my messages?

No. Turning off iMessage only stops new messages from being sent as iMessages. Your existing message history remains in the Messages app. When you turn it back on, your conversations are still there.

Why does iMessage work on Wi-Fi but not cellular?

This usually indicates a problem with your cellular data connection or APN settings. Check that Cellular Data is enabled in Settings > Cellular, and that iMessage isn’t restricted under Settings > Cellular > Messages. If it still fails, contact your carrier for assistance.

Can I send an iMessage to an Android phone?

No. iMessage only works between Apple devices. If you send to an Android phone, your iPhone will automatically use SMS (green bubble) if “Send as SMS” is enabled. If that’s off, the message will fail to send.

How long should I wait before trying a reset?

Try the quick fixes (restart app, toggle iMessage, check date/time) first. If the issue persists for more than 30 minutes and Apple’s status page shows no outage, then proceed to the network settings reset.
