How does China Unicom send short messages by landline?

The landline can't send text messages, but the mobile phone can send messages.

It has branches in 365 and 438+0 provinces (autonomous regions and municipalities directly under the Central Government) and many overseas countries and regions. It is the only telecom operator listed in new york, Hongkong and Shanghai at the same time, and has been selected for many years.

China Unicom is mainly engaged in GSM, WCDMA and FDD-LTE mobile network services, fixed communication services, domestic and international communication facilities services, satellite international private line services, data communication services, network access services and various telecom value-added services, as well as system integration services related to communication information services. On June 6, 2009, the former China United Communications Co., Ltd. and the former China Network Communications Group Company were reorganized and merged, and the new company was renamed as China United Network Communications Group Co., Ltd. In order to distinguish it from China Unicom before the merger, the industry usually called it "New Unicom".
