Cell Phone

Cell Phones  (also known as mobile phones) are media devices mainly used for wireless communication mobolized.

Description
Cell phone communication is a way of talking to someone when you are distant from their location. It involves sending your voice to another cell phone over a network involving many cell phone transmitters. When people are out of range of any towers, they have no signal and are in what is referred to as a dead zone.

For demigods, "cell phones transmit a message that says 'Hey, I'm right here!' to monsters," as Percy Jackson says. Using a cell phone for communication is very dangerous because monsters are attracted to demigod voices being sent through the air using cell phones. As a result, most demigods communicate via Iris Messaging which monsters cannot detect or track.

The Lightning Thief
Percy remarks that they are going on a quest with no supervision, not even a cell phone, as calling from one is like sending up a flare to monsters.

The Sea of Monsters
After the quest, Chiron gives Percy a cell phone to call his mother on.

The Demigod Files
In the picture of Annabeth's trunk, she has a cell phone that is off at all times.

The Last Olympian
Annabeth owns a cell phone, being one of the few demigods to do so. During the Battle of Manhattan, demigods would pick up a random cell phone from sleeping mortals to contact the demigods who owned their own cell phones, and then discard it to avoid monsters tracking them to their exact location. They used this to keep track of enemy movements and actions.

Percy Jackson also wondered if he should borrow Annabeth's phone to talk to Rachel Dare, but decided not to, because he was worried that Annabeth would get angry with him.

The Lost Hero
Annabeth lends her cell phone to Piper McLean, but asks for Piper to leave it a secret. Piper uses it to contact her father Tristan McLean, but Piper's call is unsuccessful, instead going to Tristan's secretary, Jane. During the call, Piper learns that her father has disappeared, captured by the giant Enceladus.
