The 400 numbers of the three operators are also divided into different number segments. China Telecom is 4008 and 4009, China Mobile is 4001 and 4007, and China Unicom is 4000 and 4006. Each operator has its own advantages and enterprises can choose at their own discretion.
China Telecom: its advantages are fast connection, stability and high quality. However, due to its early start, many high-quality numbers have been applied for, and it is difficult for enterprises to find good numbers.
China Mobile: mobile network is strong, and mobile phone answering will be better. Since the number call charges of section 4001 will be higher, many enterprises choose section 4007, which is still the business transferred from the original Tietong.
China Unicom: the price is relatively cheap, and it started late. There are relatively rich number resources and many high-quality numbers. Although the call quality is relatively poor, it is a good choice for many small enterprises.
When selecting a number, a general enterprise gives priority to the quality of the number. In fact, there will not be much difference in the actual application, so it only needs to select a number that is relatively easy to remember.
