If you’re unable to send or receive messages on WhatsApp, you might not have an internet connection. To check your device’s internet connection:
  • See if there's a clock icon next to your messages instead of a check mark. If there is, it means your messages aren't getting delivered.
  • Check the network signal on your device to see if it's blinking or empty.
Troubleshooting
Most connection issues can be resolved by doing one or more of the following:
Device settings
  • Restart your device by turning it off and back on.
  • Update WhatsApp to the latest version available from the Apple App Store.
  • Open iPhone Settings
    and turn Airplane Mode on and off.
  • Open iPhone Settings
    > tap Cellular and turn Cellular Data on.
  • Open iPhone Settings
    > tap Wi-Fi and turn Wi-Fi off and on.
  • Upgrade or restore your iPhone's operating system to the latest version for your device.
Wi-Fi settings
  • Try connecting to different Wi-Fi hotspots.
  • Make sure Wi-Fi stays on during Sleep Focus.
  • Reboot your Wi-Fi router.
  • Contact your mobile provider and make sure your APN settings are configured correctly.
  • Open iPhone Settings
    > tap General > Transfer or Reset iPhone > Reset > Reset Network Settings. Enter your passcode. Select Reset Network Settings. (This will delete all your saved Wi-Fi passwords).
  • If you're having trouble connecting to WhatsApp while on a Wi-Fi network that you don't normally connect to, contact the network administrator.
  • Make sure your connection isn't on a managed Wi-Fi network, such as at your office or university campus. Your network might be configured to block or limit connections.
Other settings
  • If you're using an unlocked iPhone or a pre-paid SIM card, you might need to adjust your device's APN settings for your SIM card. Contact your mobile carrier for details and instructions.
  • WhatsApp isn't designed to be used with proxy or VPN services. We don’t support these configurations.
  • Turn off roaming.
