Tablets are lighter weight and more fun than ever. Wouldn’t it be great if you knew how to make a call from iPad, instead of having to carry multiple devices everywhere? Fortunately - you guessed it - there’s an app for that!
Actually, there’s more than one. The iPad’s connectivity to the internet makes it the perfect device for VoIP calling, where calls from iPad and even to iPad can be initiated and received using an internet connection.
Skype
Skype contacts will automatically appear on your iPad when you sign in. Skype for iPad works over Wi-Fi or 3G (operator data charges may apply). You can use Skype for iPad to call anyone else on Skype, or sign up for a monthly subscription or credits to make cheap calls to landlines or mobiles from your iPad.

Viber
This app claims to help users 'avoid mobile phone bill shock”, allowing calls and texts over a 3G or Wi-Fi Internet connection to other Viber users. Viber is now compatible with the iPad, and synchs with your mobile phone number and contact list to instantly show who already has Viber (network charges may apply)

Rebtel
This app was developed specifically for use with the multi-functional iPad, featuring optimized navigation for both portrait and landscape view, higher resolution graphics and a new design. With Rebtel, calls flow effortlessly between WiFi and 3G, your iPhone address book integrates seamlessly, and you can call any other Rebtel equipped device for free - including Android phones, iPhones and even PCs.

Facetime
No doubt, the easiest way to place a phone call is using the video conferencing software that comes with the iPad. FaceTime uses your Apple ID to place phone calls to anyone who also has an Apple ID, which is anyone who owns an iPhone, iPad, iPod Touch or Mac computer. These calls are free, so even if you are using your iPhone, you won't be using your minutes. You can even receive calls on FaceTime by having people 'dial' the email address associated with your Apple ID.

Talkatone & Google Voice
Talkatone in conjunction with Google Voice has a way of placing free voice calls to anyone in the U.S., though it is a little more confusing to set up. Google Voice is a Google service designed around giving you one phone number for all of your phones. But voice calls placed with Google Voice use your voice line, and you can't do that on an iPad for obvious reasons. Talkatone extends the Google Voice service by allowing calls over the data line, which means you can use it with your iPad. You'll need both the Talkatone app and the Google Voice app.
