Public Mobile recently debuted a marketing campaign where the company wants customers to trade-in anything “useless”, for a free SIM card, as part of their SIM Swap program. These items received by Public Mobile will then be used in their ads.

There are two ways to participate:

• Social Swap: share an image on Twitter or Facebook, then order your SIM (but you need to pay $10 shipping; refunded upon activation)
• Physical Swap: you meet up with Public Mobile in person for a free SIM

Public Mobile even has posted ads on Kijij and Craigslist, advertising “WANTED—SOMETHING USELESS”, in exchange for a free SIM card.

Here are some things the carrier—owned by TELUS—has received:

Last month, Public Mobile increased their 4GB data plan option to 6GB for those choosing 90 day plans, at no extra cost.

Let us know if you’re going to meet up and exchange your junk for a free SIM card (I wonder what disgusting things employees have had to accept).
