Eva just called a moment ago. It's been so nice having her back in the states where she can be located quickly and can call whenever she wants. When she was in Brazil, I kept us in calling cards so we could talk every week. I don't even remember the name of the service we used but it could get expensive and I could only call her from my home phone.
Pingo offers cheap international calling cards and affordable international mobile phone card calls and the best part... pinless dialing! Wish I'd have known of them sooner. I could never remember my PIN when I would call Brazil so I would have to find my confirmation email with the necessary numbers.
Another bonus: you will receive up to 4 hours of free International calls just for simply signing up for Pingo.com.
