@gsuberland @neil I’m not sure if there’s a UK vs elsewhere distinction here but: in the US a “phone card” often meant something kind of like a phone company-account specific access card. It was also called a “calling card”. You’d dial a number (with an extra code/digit string to enable “calling card” mode), wait for the phone to make a “ka-BONG” sound, then dial the phone card ID number, and your call would go through and be billed to the account associated with the card. My parents gave me the phone card number for their account when I was in college in the 1990s so I wouldn’t have to worry about phone charges calling them.
