When a character needs to travel to where another person is calling him on the telephone from, he will just simply get there lickety-split by entering the receiver of the phone he's talking on, then coming out from the other receiver that the other character is calling from. Often played for Rule of Funny.
A common variation in cartoons is where characters making a Split-Screen Phone Call simply walk over to the other side of the screen.
Contrast Supernatural Phone, where a phone is used to use supernatural powers and other impossibly cool abilities. The difference between this trope and Supernatural Phone is that in that trope it is the phone that is magical. In this trope, the phone is an ordinary telephone, it is the traveler who has the special ability.
A character who can Ride the Lightning may use telephone wires as a conductor. Not to be confused with Electric Slide or instances of a certain blue police phone box vanishing into thin air.
- DC Universe hero The Atom can shrink himself down to a size where he can travel along phone lines, propelled by soundwaves. He leaves a metronome ticking at his end of the phone to provide propulsion. However, he finds out the hard way that phoning using satellite hookups results in a very rough ride for him.
- Doctor Solar is capable of travelling like this.
- The DC villainess Livewire can do this. Actually she can use any electrical wiring, but telephone wires count.
- E-Man, as an Energy Being, also has this as an ability.
- The Venom Symbiote can do this by thinning itself to a "molecular monofilament", though it can't bring its host along for the ride. At one point in the Sinner Takes All storyline, Eddie Brock extends half of the symbiote down a phone line to bond with the person on the other end (while keeping the other half bonded to himself) in order to perform a Mind Meld.
- The Matrix has a variation; the rebels use phones to jack their operatives into and out of the eponymous world. The requirement is that it must be a wired connection or "hard line," (and expanded universe material makes it clear that only certain specific wired phones will work, not any random landline telephone) not the cell phones they use to talk to their operator. One way the Agents have of trapping them is to cut the hard line. It also goes horribly awry in The Matrix Reloaded when Smith overwrites Bane's Matrix-self then uses the phone line to download himself into Bane in the real world, taking over his body.
- One of the gags in the 1970s comedy short film There Are Aliens Amongst Us.
- In Kung Fury, Hitler can shoot through a telephone line, and uses this to massacre a police station.
- Subverted in Good Omens when the demon in question has already entered Crowley's apartment the conventional way, ready to unleash the wrath of Hell on him. Crowley (also a demon) tricks him by darting into the phone line himself, prompting Hastur, his assailant, to follow him in a high-speed chase through a phone line. Crowley then turns around at the phone on the other end, races back through the line to his own apartment, and re-emerges just in time to hang up the phone, leaving Hastur trapped on an ansaphone tape. Used again when a tele-marketer calls, gets the ansaphone and thereby releases Hastur upon herself. Hilarity Ensues, but is sadly undone at the end of the book.
- Not exactly this trope, but closely related: In the ARM stories by Larry Niven, Gil Hamilton lost an arm in a mining accident, and later developed telekinetic powers that amount to a psychic replacement arm. They're short-range (literally arm's length) and he can't lift much, but he can "reach" through solid objects. Where the trope comes in: as long as his brain is convinced it's within arm's reach, he can lift it, which lets him use the power through a high-quality video connection.
- In VR5 Sidney can transport herself and anyone anyone else into virtual reality by calling them up on the phone and slamming the receiver down on the outside of her modem. The callee has no memory of the event after she hangs up.
- A few episodes of Wizards of Waverly Place have the wizards travel this way.
- In The Adventures of Superman episode "The Phony Alibi", Bungling Inventor Professor Pepperwinkle creates a system for transporting people through telephone wires. As usual with Pepperwinkle, a gang of crooks befriends the naive professor, then uses his invention for evil; they commit crimes in Metropolis, then phone themselves to distant cities and make sure plenty of people see them to set themselves up with a (seemingly) perfect alibi.
- Subverted in the Doctor Who episode "Time Heist". After picking up a call, the Doctor and Clara wake up in a dark room with two strangers and a recording, which explains that they haven't teleported through a phone but willingfully erased their own memory of what happened after they picked it up.

- d20 Modern has the spell Wire Walk, which transports you to any telephone you call, as soon as it's answered.
- Ghost Trick has this as a game mechanic. The main character and other ghosts travel to different locales via telephone. In order to learn new locations to visit, Sissel first has to listen to a conversation while the phone is in use. In general, telephones can be used anytime to teleport to any known location... except in the past, which has special rules: 4 minutes before someone's death, Sissel can only use the phone when it has established communication with another phone, and can only travel to said other phone's location. This limits a lot his moves and generates potential Unwinnable by Design scenarios where you'll be stuck in a place with no way to return because no other call will be made in those 4 minutes. Ray, aka Missile, does not have this power, which is part of the reason he had to Chessmaster Sissel into saving Lynne instead of doing it himself.
- In the third Simon the Sorcerer game, there are several phone booths placed around the city and the countryside that allow you to travel instantly from one booth to another.

- Variation in one episode of Jackie Chan Adventures when Uncle casts a spell over his landline to Jade's cell phone. Which Jackie promptly lampshades, wondering how Uncle can do that when, earlier in the episode, Jackie sent him a fax and Uncle thought the fax machine was possessed when it began printing on its own.
Jackie: He can understand sending a spell through the phone, but not a piece of paper?!
- In the Chip 'n Dale: Rescue Rangers episode "A Fly in the Ointment" Dr. Nimnul invents a "modemizer" helmet that allows him to travel through telephone lines so he can escape after committing burglaries.
