This lends itself to speculation about risks, and ways in which the street may find its own uses for these. The devices would probably cost a few hundred dollars to manufacture, and Coca-Cola would probably collect them for destruction upon delivery of the SUV. Though if one got one and didn't want to own a truck, I wonder how easy it would be to remove the SIM card and fit it to a different phone. Unless SIM cards can be configured, at the network level, to only call one number, an aspiring terrorist or troublemaker could have in their hands a completely anonymous SIM card, courtesy of Coca-Cola. Chances are it'd only be good for one call and one SMS message, though; I wonder whether it could receive calls.
