How long will SMS disappear?

"Short Message" refers to the short message value-added service provided by China Telecom to users, and it is the general name of all kinds of value-added services based on short message platform provided by China Telecom and its partners. Business content is not limited to: weather forecast, news, entertainment jokes, securities trading, interactive games, etc. SMS is also divided into: peer-to-peer SMS, SP SMS, CP SMS. The storage period of SMS is 48 hours instead of 24 hours. Suitable for mobile users of China Telecom. Short messages can be sent directly to foreign mobile phones, and there is no need to open an international long-distance function. The length of short messages is limited to 70 Chinese characters. If it exceeds the limit, it will be split into several parts and sent. Check whether all parts have been sent successfully in the short message center. If some of them are lost, it may be due to some reasons (such as the complicated routing of international SMS signaling). It is suggested that the SMS should be controlled within 70 Chinese characters as far as possible. Send SMS (inside and outside the network) 0. 1 yuan, and receive it for free. In Chinese mainland, it will be sent to the operator customers outside Chinese mainland: 0.8 yuan. Receiving is free. Domestic short messages are charged at a fixed rate, the sender pays and the receiver is free. International or regional roaming SMS is charged by call. When roaming in different countries or regions, the charging standard for sending SMS will be different. The sender pays and the receiver is free. The SMS function is turned on by default on the mobile phone, so it doesn't need to be turned on separately.
