In the UK, it is called a mobile, in the U.S. cell phone, in Latin America celular, in Japan keitai (portable), in China shou-ji (hand machine), in Bangladesh muthophone (phone in the palm of your hand), in Sweden nalle (teddy bear), in Israel Pelephone (wonder phone) and in Germany a handy.
[In Japan] If someone tries to board a bus while taking a call, the driver will not let them on, adds cultural anthropologist Mizuko Ito. "In Japan your phone shouldn't be a nuisance to others," she says. "This means generally keeping it on manner mode when out of the house, and not taking calls in cafes and restaurants. If somebody's phone rings, they will be flustered and silence it or take a very quick call."
In Spain and Italy, in contrast, mobiles are used everywhere and people discuss are not averse to discussing their personal lives in public. Renfe, the state-owned train operating company in Spain, once promoted its journeys on a poster depicting conversations people can have with their partners on cell phones from the train.
In parts of India and Africa, there is also a culture of split-second calls known as "flashing" or "beeping." Jonathan Donner, a researcher at Microsoft India who published a paper on "The Rules of Beeping," said: "Beeping is simple: A person calls a mobile telephone number and then hangs up before the mobile's owner can pick up the call."
