(n)
reminder or mobile phone call that acts as a reminder.
The intention of the caller is to remind the receiver of some particular event or task. Generally, the receiver would have made the request for a 'missed call'.
This term originated in India after the mobile boom. The caller
identification is a default feature in most of the
mobile phones; hence this peculiar use.
Oh!
Geeta just gave me a missed call; I was supposed to ring
cable operator.
