To make phone calls
- "Mrs. Weasley had braved the telephone in the village post office to order three ordinary Muggle taxis to take them into London."
- —-Harry Potter and the Goblet of Fire
A telephone is a Muggle device used to communicate long distances, and is powered by electricity. Wizards, such as Ron Weasley, underestimate their abilities, feeling the need to shout into the phone to be heard. The wizarding world equivalent is owl post and the Floo Network. Arthur Weasley frequently referred to the telephone as a "fellytone." On 1 November 1981, Vernon Dursley made "several important phone calls" while at Grunnings and later nearly dialed his home number after becoming panicked about the strange activity around him, but thought better of it. Molly Weasley "braved" using a telephone in 1994 to get 3 taxis to escort the Weasley family, Harry Potter and Hermione Granger to King's Cross Station in London to board the Hogwarts Express.
Behind the scenes
- On the main page of the J. K. Rowling Official Site in the upper right corner is a mobile telephone. Punching in 62442 on the phone's keypad (the same combination used to access the visitor's entrance of the Ministry of Magic) causes a brief voice clip of J. K. Rowling answering the phone to play.
