When a mobile device receives an incoming call from a telephone number: it identifies a number of digits associated with the telephone number and determines whether the number of digits exceeds a threshold. Upon determining that the number of digits exceeds the threshold, the incoming call is identified as an international call and the telephone number is identified as an international telephone number. The mobile device identifies a reference country from which the international call is originated and stores the international telephone number in association with the reference country in its memory. |
