  • identifying the entry of a first three dialed digits and a later dialed digit, said first three digits being dialed prior to said later digit;

    determining, in response to said first three digits, whether said later digit is a final digit of a phone number by evaluating said first three digits to determine whether said first three digits define a connected NPA code which is remotely programmed into said radiotelephone device, said connected NPA code corresponding to a geographical NPA area which overlaps or is adjacent to said first geographical NPA area; and

    automatically transmitting an origination message when said later digit is said final digit of said phone number, said origination message conveying said phone number to a telecommunication network.
