Vodafone has launched the third chapter of its Ali Wong campaign, this time turning up the heat on big telco roaming charges. Ali returns with her trademark bluntness, pointing out that another big telco charges customers double for roaming. Her message is simple: don't pay double. Roam for $5 a day. The campaign is part of a series that has taken on network, everyday pricing, and now roaming - building a consistent case that a big telco experience doesn't have to cost more.
