Remembering stuff doesn’t always have to be complicated if there’s a simpler way. That’s what the people at primacall thought when they introduced a mnemonic to their latest campaign, promoting the telecommunications provider’s flat rate offers. Since mnemonic means „Eselsbrücke“ in German, a cartoon donkey performed a dance around primacall’s 01038 prefix number. Easy way to remember, easy way to save. To make that number stick with heavy phone users, we had the commercial aired on TV channels n-tv, Tele 5 and others in December 2010.
