Talkatone by TalkMe.IM, Inc turns your iPad into a phone, allowing you to place unlimited calls and texts to any location around the world for free by using WiFi or 3G/4G.
There is no need to use your cell phone minutes to chat. Instead, download the app on your iPad and start enjoying limitless free calls and texting. This app is absolutely essential if you plan to do any travelling. Why pay roaming fees when instead you can chat for free? If you're overseas you can text and call the US and Canada for free.
If you need to make a call to an international number, not to worry as the rates are extremely cheap. You can text and call even if you don't have cell coverage in a particular area.
The app uses a single interface to all messages to your Google and Facebook contacts. Unlike VoIP and Skype you can make calls to anyone, even if they don't have the app installed.
There are some things to note however before using this app. If you're making a call to a landline phone in Canada or the US you will need a Google Voice account. As well, the SMS feature only works for US users.
Talkatone was updated on Dec. 3, 2012 and has 1,050 customer ratings with an average rating of four out of five stars.
I found this app extremely easy to use on my iPad. Both the texting and calling features work exactly how you'd expect so there is no learning curve here.
For: iPhone, iPod touch, and iPad with iOS 4.3 or later
