• encounter issues sending or receiving messages or downloading media;
• see a clock next to sent messages;
• see Unknown under your Account expiration (To check, go to: WhatsApp > tap on the three dots at the bottom right > settings > account);
• have problem updating your profile or status or favorites list.

The most common reason is that your phone is not connected to the internet.

Please try these steps

2. Make sure that you have a data plan on your carrier's network or a Wi-Fi connection with a working internet access.

I still cannot connect

Some carriers commonly have issues with WhatsApp on Windows Phone, even if it has worked before on other platforms. If websites and other apps are working but WhatsApp cannot connect, it is possible that your network configuration does not permit the type of connections (socket or non-HTTP connections) necessary for WhatsApp.

Please check the following:

• Check your carrier's Access Point Name (APN) settings. There may be a different APN for your carrier that allows non-HTTP connections like WhatsApp.
• Contact your carrier for APN settings that permit non-HTTP connections. To change your APN settings, please go to settings > cellular.
• If you have a Windows Phone made by Nokia, try using the Connection Setup app from the Nokia Collection in Marketplace (this application may not be available in some countries).
• If you change the APN settings, please be sure to restart your phone for the changes to take effect.
