Ting is a new way of doing business in the mobile space. The newest division of Tucows aims to simplify mobile. Basically, Ting users pay for what they use. They aren’t penalized for going over, their plan just makes the jump to the next service level without any overage charges. The kicker is this: If a Ting user uses less than they anticipated, they automatically receive a credit on their next bill.
