I cannot connect to WhatsApp!

Connection issues are usually caused by your phone settings, or problems with your internet connection or mobile provider. In most cases, internet connection problems are temporary and your messages will be sent and received as soon as you move to a place with a stronger signal.

Also, sometimes messages take awhile to send and receive. There are many reasons a message might take a while to be delivered to the other person and only display a single check mark. For example: your friends' phone may be turned off, they may not have any data credits left, or they may be in a spot out of coverage.

If you are still having problems with message delivery, we recommend that you try these steps:

  1. You have the latest version of WhatsApp for your phone available here.
  2. Check to make sure that your phone is connected to the internet with a strong signal. Try opening a webpage.
  3. Check to make sure your phone is not using a WAP only connection. WhatsApp uses non-HTTP/non-web socket data channels to send and receive messages, so you will need a data plan in order to use WhatsApp on your Nokia phone.
  4. Check to make sure your phone is not using a proxy connection. If you are not sure your phone uses this type of connection, we recommend you contact your mobile provider and ask them.
  5. If you still cannot connect, try rebooting your phone.

Still stuck? Your mobile provider may be blocking the specific data channel that WhatsApp uses to send and receive messages.

If you ask your mobile provider for steps to unblock non-HTTP/non-web socket connections, they may be able to help you configure your phone. Contact your mobile provider and ask them how to allow non-HTTP/non-web socket connections on your phone. They will guide you through a process in which you will manually configure your data network and web settings.
