I got the fido 3GB for $15 deal and am trying out some options right now to become my permanent cell phone solution.
Voip.ms is around $1USD/month to have a phone number. And $0.01c/min for all calls. SMS is included and free. although they say SMS is in beta and "free for now". Who knows if they'll ever start charging. Calling can be done through and sip app. SMS is done through the voip.ms SMS app. But can also be sent/received in the web portal if you want to.
Fongo is free to have a phone number. Free incoming texts and $2/month for unlimited texting. All calls and sms must be done through the fongo mobile app.
So no. no free. but about 2 bucks per month gets you something good and reliable. As in the company won't fold suddenly.
