Two firms in the Nippon Telegraph and Telephone Corp. group unveiled plans Friday to lower charges for fixed-line phone services to the same level as those offered by rival carriers KDDI Corp. and the Softbank group.

NTT East Corp. and NTT West Corp. said they will cut the basic monthly charge by 50 yen from the current 1,750 yen for household users in urban areas and abolish the 390 yen monthly fee for using touch-tone services, beginning January.

The firms also suggested they would eventually scrap the 72,000 yen in initial subscription fees used to finance construction of their facilities.
