Almost everyone who owns an iPhone will be tied into some sort of contract that enables them to send a certain number of text messages free of charge. All too often, this limit is reached very quickly and it is very easy to start to build up a large bill.
Textfree Unlimited - Send Text Messages (SMS) Free! is a free tool that enables you to send and receive free text messages both from your idevice or from the web. It is also possible to send and receive picture messages almost anywhere in the world.
The text only version of the software has been superseded by a version that also supports voice calls. The app is likely to be of particular interest to iPod owners as it essentially enables them to transforms their music player into a phone.
While the app does allow for free phone calls, you are reliant on a wifi connection for the best possible call quality. Textfree with Voice - Free Text and Pic Messaging (SMS & MMS) plus Calling include 10 mins of free calls, but more can be earned by simply installing and running apps.
