WhatsApp is a messaging app that is used by millions of people around the world. It has been in beta for a while now and is currently available on both Android and iOS devices. The app was first released in 2014 and has since been used by over 1 billion people. To use WhatsApp on a SD card, you will need to create an account and set up your preferences. Once you have done that, you can install WhatsApp on your SD card. To do this, open WhatsApp and click on the three lines in the top left corner of the screen. On Android devices, this will be called “Settings.” On iOS devices, this will be called “My App.” Under “Apps,” select WhatsApp and then click on the SD card icon at the bottom of the screen. Once WhatsApp has been installed on your SD card, you can start using it just like any other app. To start messaging someone, just open WhatsApp and type their name into one of the chat boxes. You can also send messages with just a few taps if you want to send a message quickly or if you want to include more information in a message than what is available in the chat box.
