If you're young: To let your parents know you're still alive and well and where the hell you're at, how long, when you'll be back, etc.
To call work, school, make appointments, order stuff, contact family/friends, and to keep up to date with things.
Keep yourself occupied with bored with games, music, videos, and whatever else you do.1
