With T-Mobile, you can use your cell phone worldwide without crazy fees! But not Jeremy. He went to Europe with AT&T and racked up a $74,787 bill. When his parents’ TV ads couldn’t reach him, fans were driven to an online game with clues from Jeremy’s social media. There, they could pin him to a map for a chance to win their own trip. We used real AT&T phones across 10 cities to rack up the bill and developed Jeremy’s voice with over 2,000 social posts. In the end, T-Mobile’s CEO paid Jeremy's bill.
