Mobile phone provider Wind Mobile has begun a Valentine's Day-themed campaign called "Call-A-Sutra." Until Feb. 15, the company will post a series of "sensual smartphone positions" on its Facebook page and encourage visitors to share them with their partners and friends. "We know it's sometimes challenging to keep the dialogue fresh in a relationship, and this Valentine's we want to give people a few new ideas," said Anthony Lacavera, chairman and CEO of Wind Mobile. "Call-A-Sutra plays on expectations with double-entendre headlines that would lead you to imagine one thing while the actual position described reveal truisms about how we use our phones. The Call-A-Sutra positions are a fun way to get in the mood and have a laugh with a loved one at the same time." The campaign was developed by MacLaren McCann. Wind Mobile is a division of Globalive Holdings.
