10 Tech How-To

Fix Facebook Messenger Not Sending Messages

Guide 10-12413 · Updated · Step by step

If Facebook Messenger isn’t sending messages, the fix is usually a bad internet connection, an outdated app, or a temporary server glitch. Start by checking your Wi-Fi or mobile data, then force-closing and reopening the app; if that fails, clear the app’s cache or reinstall it. Below are the exact steps for each cause, plus answers to common follow-up questions.

Why Messenger Stops Sending Messages

Messenger relies on a persistent connection to Facebook’s servers. When a message won’t send, it’s almost always one of these:

  • No or weak internet connection – the app can’t reach the server.
  • App glitches or corrupted cache – temporary files interfere with sending.
  • Outdated app version – bugs that were already fixed in an update.
  • Facebook server outage – the problem is on their end, not yours.
  • Account restrictions – a temporary block or security flag.
  • Device storage full – the app can’t write message drafts or attachments.

Most fixes take less than two minutes and don’t require technical skill. Work through the steps below in order; the most common cause (connection) is first.

Quick Fixes to Try First

  1. Check your internet connection. Open a web page or stream a video. If that fails, toggle airplane mode on and off, or restart your router.
  2. Force-close Messenger. On Android: Settings → Apps → Messenger → Force Stop. On iPhone: swipe up from the bottom and swipe the Messenger card away.
  3. Restart your phone. This clears temporary network and app glitches.
  4. Update Messenger. Go to the Google Play Store or Apple App Store, search for Messenger, and tap Update if available.
  5. Check Facebook’s server status. Visit downdetector.com (or search “Messenger down”) to see if others report issues. If there’s an outage, wait an hour.

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

Clear the App Cache (Android and iPhone)

A corrupted cache is a frequent cause of messages stuck on “Sending.” Clearing it doesn’t delete your conversations—only temporary files.

Android:

  1. Open Settings → Apps → Messenger.
  2. Tap Storage & cache.
  3. Tap Clear cache (not Clear storage—that logs you out and removes drafts).
  4. Reopen Messenger and try sending again.

iPhone: iOS doesn’t offer a per-app cache clear. Instead, offload the app:

  1. Settings → General → iPhone Storage → Messenger.
  2. Tap Offload App (this keeps documents and data, but removes the app itself).
  3. Tap Reinstall App from the same screen, or download from the App Store.

After clearing or offloading, log back in and test.

Reinstall Messenger (When Nothing Else Works)

A full reinstall fixes deeper corruption and also clears any stuck permissions. Steps:

  1. Delete Messenger from your phone (long-press the icon and choose Remove/Uninstall).
  2. Restart your device.
  3. Download Messenger from the official app store and log in.

Your chat history is stored on Facebook’s servers, so you won’t lose messages. You may need to re-enter your phone number for two-factor authentication.

Check for Account Restrictions or Blocks

If you can send messages to some people but not others, you might be temporarily blocked by the recipient, or your account may have a restriction. Signs include:

  • Messages show a red exclamation mark or “Not Delivered.”
  • You can’t send to a specific person, but can to everyone else.
  • You see a notice like “You can’t message this person right now.”

If it’s only one person, they may have blocked you or changed their privacy settings. If it’s everyone, try logging out and back in, then check your account status at facebook.com/help. If Facebook has flagged your account (often for spam-like behavior), you’ll see a prompt to verify your identity—follow it.

Free Up Storage and Update Your OS

Low storage can prevent Messenger from saving attachments or even sending text. On Android, check Settings → Storage. On iPhone, Settings → General → iPhone Storage. If you’re under 1 GB free, delete unused apps or photos.

Also make sure your phone’s operating system is up to date. An outdated OS can cause compatibility issues with the latest Messenger version. Go to Settings → System → System Update (Android) or Settings → General → Software Update (iPhone).

When the Problem Is on Facebook’s Side

Even if downdetector shows no outage, Messenger can have regional issues. To confirm, try sending a message from the Facebook website (facebook.com) on a computer. If that works, the problem is your app or phone. If it also fails, it’s a server issue—wait and try again later. Facebook usually resolves outages within a few hours.

Another trick: switch between Wi-Fi and mobile data. Sometimes a specific network (like a public Wi-Fi) blocks Messenger’s ports. If you’re on Wi-Fi, turn it off and use cellular data, or vice versa.

Frequently Asked Questions

Why do my messages show “Sending” forever?

This means the app hasn’t received confirmation from Facebook’s server. Usually it’s a weak connection—move closer to a router or switch networks. If it persists, clear the cache or reinstall. A server outage can also cause this, so check downdetector.

Will I lose my conversations if I uninstall Messenger?

No. Your chat history is stored on Facebook’s servers, not on your phone. When you log back in, all past messages reappear. You may lose unsent drafts or locally saved photos that weren’t uploaded.

Why can’t I send photos or videos but texts work?

Media files require more bandwidth and storage. If texts send but media fails, your connection is too slow, or your device is low on storage. Try sending a small image first. Also check that Messenger has permission to access your photos (Settings → Apps → Messenger → Permissions).

Does clearing the cache delete my messages?

No. The cache only stores temporary data like thumbnails and login tokens. Your actual conversations are on Facebook’s servers. Clearing cache is safe and often fixes sending issues.

Why does Messenger work on Wi-Fi but not mobile data?

Your mobile carrier may be blocking the connection, or your data plan might be throttled. Check if other apps load on mobile data. If they do, try resetting your network settings (Settings → System → Reset Options → Reset Wi-Fi, mobile & Bluetooth). If only Messenger fails, it could be a temporary carrier issue.

Can I send a message from a computer if the app is broken?

Yes. Go to messenger.com or facebook.com and log in. You can send and receive messages there. This is also a good test to determine if the problem is app-specific or account-wide.
