The graph of the phone calls in the United Kingdom UK shows us that how the relationships between the use of three types of telephone calls has changed been changing since 1995, and how they have become became less significant in as of 2002.

     In the 1990s, the use of local/fixed lines was were the most important significant, and it prevailed over the all other types of calls calling methods. All three types were increasing increased simultaniously nearly in the same correlation between themselves till through 2000, when the use of local/fixed line calls has started to reduce started falling-off.

     Use of National and international calls calling was raising rose steadily without any drastic change until 2002, while cellular telephone calls from the mobiles became more frequent, and we can see the graph shows the extent of their popularity how they were extending during these those years.

     The growth difference of mobile calling during the three years since between 1995 till and 1998 was about 10 billions of minutes, while the scale during during the period between 1998 and 2001, gives us the triple of the previous gap tripled to in about almost 30 billion of minutes.
