Caller ID

Caller ID is a telecommunication service that enables users to identify incoming calls before answering. Caller ID is possible with mobile, analog, digital and VoIP calls. 

Depending on the device being used, Caller ID displays on the device screen as a long number at the moment the call connects.  

Users can store numbers on their personal devices using either the SIM card or the device memory for storage. Storing the number allows users to save the number under a recognizable name for quick recognition. This name is then displayed every time the stored number calls. 

Caller ID is used for caller identification when receiving text messages, as well
