A driver stops for gas and their smartphone buzzes with a text offering a free coffee inside the gas station. What does mobile provide advertisers that enables them to offer this to customers?

Mobile devices provide advertisers with "context," which refers to real-time information about a user's location, time, and current activity. In this scenario, the driver's smartphone location data indicates they are at a gas station, allowing the advertiser to deliver a timely and relevant offer for coffee. This contextual relevance makes the advertisement much more effective. "Cell signals" are the underlying technology for communication but don't inherently provide the actionable user context. "Customer profiles" contain historical data about user preferences but don't capture the immediate, real-world situation like being at a gas station. "Wi-Fi" is a connectivity method, but it's the location data derived through various mobile technologies (including GPS, cell tower triangulation, and Wi-Fi positioning) that provides the crucial contextual information.
