My ex-wife grew up in a small town in 1970s Francoist Spain, so I've heard these types of stories before. (Though she didn't have to crank her phone!!)

She actually had two phone lines in her house: One for employees of Repsol - the national oil company - which didn't have a dial and used a central operator, and another with a dial to make regular calls. It created a sort of 1970s "blue bubble" effect because the company line was free to use. Friends whose family also worked for the company were sort of privileged as a result.

Visiting my kid's grandparents in the late 2000s was a blast from the past as they still had the same pink phone in the living room they had had since forever (it may have even been a rotary phone, I can't remember). My son at the time was honestly perplexed at the whole idea of a landline.
