Unfortunately, WhatsApp is not officially supported on Nokia 6300 as it runs on the Series 40 operating system, which is not compatible with WhatsApp. WhatsApp currently supports Android, iOS, Windows Phone, and some older versions of Nokia phones running on Symbian and Nokia S40 operating systems. If you want to use WhatsApp on your Nokia 6300, you may want to consider upgrading to a newer phone that supports WhatsApp or using an alternative messaging app that is compatible with Series 40, such as Facebook Messenger or Skype. Alternatively, you can use WhatsApp on your computer by downloading and installing the WhatsApp desktop app or using WhatsApp Web.
