When does Black Butler take place?


In chapter 3 or 4 of _Black Butler_ , Sebastian is using a mobile phone when
talking to those guys who are holding Ciel captive.

Is this a mistake by the author or something else? Isn't _Black Butler_ in the
1800s?




In the manga chapter 27 page 41, it was shown that Ciel Phantomhive was born
in 1875. Googling with the key phrase "the first cell phone" tells us that the
first mobile-phone was created in 1973 by Motorola, which is 100 years after
Ciel was born.

Since Ciel was 13 (12 during the first 14 chapters) in the story, mobile
phones should not have existed. Thus, like [lentinant said in his

butler-take-place#comment46621_33884), it is likely that the story takes place
in an alternate reality.
