Skype is a free VoIP (voice over Internet Protocol) application for a number of operating systems and mobile platforms. Using Skype, you can make free or discounted phone calls all over the world with an Internet connection. If you're experiencing call quality issues while using Skype, you can make adjustments to improve your reception. In turn, you should have clearer audio, less lag and fewer drops while making Skype calls.

With cell phone use on the rise, payphones are becoming a thing of the past. However, because not everyone owns a cell phone, has a signal or a charged battery, payphones are still around, albeit not as convenient as they once were.
