See who is calling you before you answer a call with the Calling Line Identification Service.
With the Calling Line Identification service you see on your mobile phone’s screen the number of the person that is calling you or his/her name, if the number is stored in your contacts list, provided that the caller has not activated the Calling Line Identification Restriction service or uses a network that does not support the service in question.
Calling Line Identification also makes your own number visible to others, unless you have selected not to reveal it.
