Learning how to set up and use Skype for iPad and iPhone to make free voice and video calls worldwide is quite simple. The steps below more or less work the same for the iPad and the iPhone as they both run the same operating system. But, there are some minor differences in the hardware.
You can use the integrated microphone and speaker of your device or pair a Bluetooth headset to it. You'll also want to ensure good internet connectivity through your iPad’s or iPhone’s Wi-Fi connection or 3G data plan.
If you don’t already have a Skype account, register for one. Setting up an account is free, and if you have been using a Skype account on other machines and other platforms, it will work perfectly on your iPad and iPhone. A Skype account is independent of where you use it, which means if you already have a Skype account, you don't need to create a second one specifically for your iOS device.
When you have Skype contacts in your contact list, you can simply tap their names to call, video call or send messages to them. These contacts get automatically imported to your iPad or iPhone if you are using an existing Skype account on which they are found. You can always enter new contacts in your list, either by entering their names manually—just tap the people icon at the top right of the Contacts list—or you can search for contacts to add using the search bar in the Contacts tab.
