Sorry but there is no way you can download and install WhatsApp in Samsung Chat E2220 because the mobile handset has a very low operating system in which the messenger application is not compatible with. The handset only has a proprietary operating system. This kind of operating system can only install java applications and unfortunately WhatsApp is not just a java application. Therefore, Samsung Chat E2220 has no capability to download, install, and use WhatsApp and sad to inform you but you cannot connect with your friends and family with this messenger application. Aside from low operating system, Samsung Chat E2220 cannot download, install, and use WhatsApp because it does not have the capacity to be strongly connected to the internet. One of the system requirements of the messenger application is that the mobile handset should be able to connect to the internet either via a packet data plan from the network service provider or through an available Wi-Fi connection on the area. However, Samsung Chat E2220 does not have capability to connect to the internet through Wi-Fi, thus it would not be able to use the features of WhatsApp.
