What is a 400 phone?

400 telephone is a shared service between the calling party and the called party, that is, the calling party bears the local telephone access fee and the called party bears all the incoming call answering fees. At present, it is widely used in multi-industry pre-sales and after-sales service consultation.

400 telephones are divided into 4006 (China Unicom), 4007 (China Mobile's former Tietong), 4008 (China Telecom), 400 1 (China Mobile's new section), 4000 (China Unicom's new section) and 4009 (China Telecom's new section).

The 400 telephone is a virtual phone switchboard designed for enterprises and institutions with unified numbers all over the country. All incoming calls to the 400 switchboard number are transferred to the preset fixed telephone, mobile phone or call center line. The 400 telephone switchboard is only responsible for handling incoming calls, not outgoing calls.
