Dial 1-800-COLLECT and let the operator know you're calling collect — MCI's dial-around service promised cheaper collect calls than your payphone's default carrier. One of the most aggressively advertised services of the 1990s, it burrowed into Gen X's brain via TV spots with celebrity spokespeople.
Coin-operated public telephones on street corners, in malls, and outside every gas station — the fallback when you needed to call home or were out of pocket change. At their 1990s peak, the US had over 2 million payphones; by the 2010s, they'd nearly vanished.
