What is the iMessage Activation Error?

It is a common glitch that iOS users encounter when trying to activate iMessage on their devices. This error often pops up with a notification saying, “Activation Unsuccessful. Turn on iMessage to try again.”

Reasons the error

  2. Step 2: Reset Your Router: Still no luck? Try resetting your router. Unplug it, wait for a few minutes, then plug it back in. Give it a moment to restart, then reconnect your iPhone to the Wi-Fi network.
  3. Step 3: Connect to a Different Wi-Fi Network: If the issue persists, try connecting to a different Wi-Fi network. This will help you identify if the problem lies with your current network.
