     FIELD OF INVENTION 
       [0002]    A need has arisen to increase the speed of delivery of information transmitted through the telephony and mobile service industries in a cost efficient manner in the telecommunication industry. International calling boundaries have been blurred by the rapid evolution of telecommunication technologies. 
         [0003]    This invention is a novel communication solution that allows its users to maintain one number throughout the world and that further allows each user to initiate their own international calling card service via the number, regardless of wherein they are physically present. 
       BACKGROUND 
       [0004]    Presently, roaming facilities are available to international travelers when traveling through foreign countries. When an individual moves to a new country from a country wherein he or she is being provided a specific radio frequency telephone service, using a distinct number from his home country, he or she normally will have to purchase a new card from the switch operators of the particular country to keep connected while remaining in the new country. A problem arises when the individual is provided with the new card to receive the services in the new country, for the individual will not be able to keep his or her original number. This causes problems to the individual and all of his or her contacts that contacted the original number. From this point forward the individual shall be referred as the roamer. 
         [0005]    The present invention allows the roamer to remain connected to his or her contacts using his or her distinct number, when in foreign territories, in a cost efficient manner. Presently, some phones are able to roam into foreign territories in a cost prohibitive manner. The present invention also allows the roamers to connect to their contacts in their the home country, when in a foreign country, by allowing them to dial their home country code from their telephones even though the card they are using uses a different code than the one being used by the new country operators. 
         [0006]    The present invention is a novel system that allows the roamer to roam internationally, using the roamer&#39;s home specific phone number, via incoming and outgoing calls, in a cost efficient manner, and that further allows the roamer the ability to start an international calling card service. The present invention also allows the roamer to maintain one telephone number throughout the World, thereby allowing him to communicate with all his or her contacts in a manner that will not disrupt his or her business or personal life. 
       SUMMARY 
       [0007]    The present invention is a novel system that allows a roamer to roam internationally, using the roamer&#39;s home specific phone number, via incoming and outgoing calls, in a cost efficient manner, and that further allows the roamer the ability to start an international calling card service. The novelty of the present invention is that the roamer doesn&#39;t lose his real number, which is the roamers connection to his or her family, friends, relatives and business, when traveling outside of the roamer&#39;s home country. 
         [0008]    An object of the present invention is to provide a unique worldwide telecommunication service that provides international roaming services to users by enhancing the mobility of their incoming and outgoing voice calls at very nominal usage charges. 
         [0009]    Another object of the present invention is to create an efficient long distance telecommunication service that will blur international boundaries in a cost efficient manner. 
         [0010]    A further object of the present invention is to create a complete platform that would allow its operators to initiate and create their own retail calling card businesses. 
         [0011]    Still a further object of the present invention is to provide a unique thread that international roaming facilities may avail when connecting to the users of the thread, thereby reducing the costs of roaming when the users are not in the home country wherein the thread originated, the unique thread being associates to a specific telephone number.
