Is it legal for Unicom to recover 10 years of historical arrears?

It is their legal right (but not necessarily successful) for Unicom to recover the telephone charges of the old Netcom fixed line from you. At the same time, you also have the right to defend yourself according to law, such as prescription and evidence.

China Unicom was established in July 1994. The establishment of China Unicom broke the monopoly management system of basic telecom services in China for the first time and became a milestone in the reform and development of China Telecom.

China Unicom has set up more than 300 branches and subsidiaries in 3/kloc-0 provinces, autonomous regions and municipalities directly under the central government. In June 2000, China Unicom Co., Ltd. was listed in new york and Hongkong respectively, which took an important step for China Unicom to enter the international market.

Since the establishment of China Unicom, various businesses have developed rapidly and the overall strength has been continuously enhanced. Its telecom services include: mobile phones (including GSM/KOOC-0/30 and CDMA/KOOC-0/33), long-distance calls/KOOC-0/93, local calls and data communications (including Internet services/KOOC-0/65 and Internet services/KOOC-0/79/KOOC-0/79).
