iMessage Signed Out Error: Fixes That Work

The “iMessage is signed out� error means your iPhone, iPad, or Mac has lost its connection to Apple’s iMessage servers, usually due to a network, date/time, or account issue. You can fix it in most cases by signing back into your Apple ID in Settings > Messages, toggling iMessage off and on, and checking your network connection.

Why iMessage Signs You Out

iMessage relies on a constant, secure connection to Apple’s servers. When that connection drops, Apple may automatically sign you out to protect your account. Common triggers include:

• Switching Wi-Fi networks or cellular carriers
• Restarting your device or updating iOS
• Entering the wrong Apple ID password too many times
• Apple server outages (rare but real)
• Date and time being set incorrectly, which breaks the encryption handshake

Unlike regular SMS, iMessage uses end-to-end encryption. Your device and Apple’s servers need to verify each other’s certificates, and that verification depends on an accurate clock. If your date, time, or time zone is off by even a few minutes, the connection can fail and you’ll see the signed-out message.

Quick Fixes to Try First

Before diving into deeper troubleshooting, try these simple steps. They resolve a large percentage of sign-out errors:

1. Toggle iMessage off and on: Go to Settings > Messages, turn off iMessage, wait 10 seconds, then turn it back on.
2. Restart your device: A full power cycle clears temporary network glitches.
3. Check Apple’s system status: Visit apple.com/support/systemstatus to see if iMessage is down for everyone. If it is, wait and try again later.
4. Switch networks: If you’re on Wi-Fi, try cellular data (or vice versa). Sometimes a router firewall blocks Apple’s ports.
5. Verify date and time: Go to Settings > General > Date & Time and enable “Set Automatically.�

If none of these work, move on to the more thorough fixes below.

Sign Back Into Your Apple ID

The most direct fix is to sign out of your Apple ID on the Messages app and sign back in. Here’s how:

1. Open Settings and tap your name at the top.
2. Scroll down and tap Sign Out (this signs you out of iCloud, App Store, and all Apple services on that device).
3. Restart your device.
4. Go back to Settings, tap Sign In, and enter your Apple ID and password.
5. After signing in, go to Settings > Messages and make sure iMessage is toggled on.

This forces your device to re-authenticate with Apple’s servers. If you have two-factor authentication enabled, you’ll need to enter the verification code sent to your trusted devices or phone number.

If you don’t want to sign out of your entire Apple ID, you can try a more targeted approach: go to Settings > Messages > Send & Receive, tap your Apple ID, then tap Sign Out. This signs you out of iMessage only, not iCloud. Then sign back in with the same Apple ID.

Network and Carrier Settings

iMessage needs to reach Apple’s servers on specific ports. If your network blocks them, you’ll get signed out. Try these network-related fixes:

• Reset Network Settings: Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. This clears saved Wi-Fi passwords and Bluetooth connections, so you’ll need to rejoin your Wi-Fi network.
• Update carrier settings: When a carrier settings update is available, you’ll see a pop-up. You can also check manually: go to Settings > General > About and wait a few seconds. If an update is available, a prompt will appear.
• Use a different DNS: Some ISPs’ DNS servers have issues resolving Apple’s domains. You can change your Wi-Fi DNS to 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare) in Settings > Wi-Fi > (i) next to your network > Configure DNS.
• Check for VPN or firewall: If you use a VPN, try turning it off. Some corporate or school networks block the ports iMessage uses (5223, 443, and 80).

After changing any network setting, toggle iMessage off and on again to force a new connection.

Date, Time, and Region Settings

As mentioned, iMessage’s encryption relies on an accurate clock. If your date and time are wrong, the secure connection can’t be established. Here’s what to check:

1. Go to Settings > General > Date & Time.
2. Enable Set Automatically.
3. If it’s already on, turn it off, manually set the correct date and time, then turn it back on.
4. Also check your region: Settings > General > Language & Region. Make sure the region matches where you are, as this affects time zone and formatting.

A common misconception is that changing your time zone to “trick� an app is harmless. For iMessage, it can actually cause the sign-out error because the security certificates are time-sensitive. Always keep “Set Automatically� enabled unless you have a very specific reason not to.

What to Do If Nothing Works

If you’ve tried everything above and still see “iMessage is signed out,� there are a few last-resort options:

• Update iOS: Go to Settings > General > Software Update. Apple frequently fixes iMessage bugs in minor updates.
• Erase All Content and Settings: This is a drastic step, but it can clear corrupted settings. Back up your device first, then go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings. After the reset, restore from your backup and sign in to iMessage again.
• Contact Apple Support: If the error persists, it may be an account-level issue. Apple Support can check if your Apple ID is flagged or if there’s a problem with your phone number registration.

Remember that iMessage is free over Wi-Fi or cellular data, but if you switch to SMS (green bubbles), standard carrier text message rates apply. The sign-out error only affects iMessage; you can still send and receive regular texts.

Frequently Asked Questions

Why does iMessage keep signing me out on my Mac?

On a Mac, the same network and date/time issues apply. Go to Messages > Settings > iMessage and sign out, then sign back in. Also check that your Mac’s date and time are set to automatic in System Settings > General > Date & Time. If you use a firewall, make sure it allows incoming connections for Messages.

Will I lose my messages if I sign out of iMessage?

No. Signing out of iMessage does not delete your messages. They remain on your device and in iCloud (if you have iCloud Backup enabled). When you sign back in, your message history reappears.

Can I use iMessage without an Apple ID?

No, you need an Apple ID to use iMessage. You can create one for free at appleid.apple.com or directly on your device. If you don’t have an Apple ID, iMessage won’t work, and you’ll see a different error message prompting you to sign in.

Does resetting network settings delete my photos or contacts?

No, resetting network settings only clears Wi-Fi passwords, Bluetooth pairings, and cellular settings. Your photos, contacts, and other data are untouched. You’ll just need to re-enter Wi-Fi passwords afterward.

Why does iMessage work on one device but not another?

iMessage is tied to your Apple ID, but each device signs in independently. If one device has a network issue or an outdated iOS version, it may get signed out while others work fine. Check the date/time and network settings on the affected device specifically.
