This original post was from 2010 - 7 years ago. If you read through the post other users have already made their suggestion that worked for that period. Viber or Skype to go did not exist then. Adoption of smart phones were just picking up. Everybody now knows all these alternatives. Nobody goes to services like tringtel now. You guys are making suggestion to 7 year old post with present day alternatives. At least look at the dates.
