What does "Waiting for This Message" mean on WhatsApp?

The short answer

“Waiting for this message. This may take a while.” means WhatsApp can’t decrypt the message yet because your phone hasn’t received the encryption key it needs to read it.

Why does this happen?

WhatsApp uses end-to-end encryption, which means every message is locked with a unique key. Your phone needs that key to unlock and display the message. This placeholder shows up when the key hasn’t arrived yet.

Common reasons include:

  • The sender’s phone is offline — the encryption key gets sent from their device, so if their phone is off or has no internet, the key can’t reach you
  • You recently reinstalled WhatsApp — your new installation needs to re-establish encryption with your contacts
  • You switched to a new phone — similar to reinstalling, the encryption setup needs to happen fresh
  • The sender is using an outdated version of WhatsApp — older versions can have trouble sending encryption keys properly
  • Poor internet connection — either on your end or the sender’s end

How to fix it

  1. Wait it out — in most cases, the message will appear on its own once the sender’s phone comes back online
  2. Ask the sender to open WhatsApp — their phone needs to be online and have WhatsApp running to send the encryption key
  3. Ask the sender to resend the message — this is often the quickest fix
  4. Check your internet connection — make sure you’re connected to Wi-Fi or mobile data
  5. Update WhatsApp — make sure both you and the sender are running the latest version
  6. Restart your phone — this can help re-establish the connection to WhatsApp’s servers

When should you worry?

This message is almost always temporary and harmless. However:

  • If every message from a contact shows this, their phone may be off for an extended period or their account may have an issue
  • If it happens across all your chats, try uninstalling and reinstalling WhatsApp (make sure to back up your chats first)
  • This is not a sign that someone blocked you — blocked contacts look different on WhatsApp
