The typical Android tablet doesn’t come with the Skype app preinstalled. To get Skype, visit the Google Play Store and obtain the Skype app. In case you find multiple apps, get the one that’s from the Skype company itself.
To use Skype, you need a Skype account. You can sign up while using the app, or you can visit Skype.com on a computer to complete the process by using a nice, full-size keyboard and widescreen monitor.
When you start the Skype app for the first time, work through the initial setup screens. You can even take the tour. Be sure to have Skype scour the tablet’s address book for contacts you can Skype. This process may take a while, but if you’re just starting out, it’s a great help.
Skype is free to use. Text chat is free. Voice and video chat with one other Skype user is also free. When you want to call a real phone, or video-chat with a group, you need to boost your account with Skype Credit.
It’s doesn’t cost extra to do a gang video chat in the Hangouts app.
Don’t worry about getting a Skype number, unless you plan to receive Skype phone calls on your tablet. Those phone calls include calls from any phone, not just a mobile device using the Skype app. So, unless it’s your ultimate desire to transform your Android tablet into a cell phone, don’t bother with the Skype number.
