Pocket ialing, or pocket-calling, happens when a person's mobile phone accidentally dials someone, often unbeknownst to the person whose phone is making the call. The phone is usually located in the dialer's pocket or purse, hence the name "pocket dialing". The recipient of the call usually hears a loud and random noise when they answer the phone, and if they do not hang up and the caller remains unaware, will sometimes receive information the caller would rather not disclose.
