iCall is an awesome service that has continued to grow throughout the years. It's a software similar to Skype, but allows users to make unlimited calls for free within the United States, most impressive is the fact users can make calls to computers, andddd landlines and mobile phones for free. We tried a few calls from computer to cell phones and it's very clear. However if users want to make international calls or have your own phone number then you have to pay a small fee.
What we like about iCall is just how much they give away for free and the quality seems legit so far, with chatting and video conference capabilities, we are starting to think this may be even better then Skype
