Can I withdraw the text message I sent?

Cannot be withdrawn. \x0d\ After all, SMS is not a callback function of QQ and WeChat. SMS is sent through the service provider's relay station. If SMS has callback function, it is necessary to realize instant communication between users and service providers. As we all know, you should contact the communication service provider and find your message. At this time, people who may have received the text message have seen it, so there is no need to withdraw the message. In order to establish instant communication between communicators and communication service providers, more procedures and service personnel are needed to maintain it. In this era of frequent information exchange, there is no need to spend so much manpower and financial resources to do this, so the function of SMS cash withdrawal cannot be realized. \x0d\ SMS was the most convenient communication method except telephone at first, but with the development of society, a large number of communication methods have changed, and SMS has lost many advantages, such as cost and word limit. The current communication methods such as QQ and WeChat have the advantages of timeliness and low cost. However, SMS still has advantages, for example, you can accept SMS without always opening the internet, and there are reminders such as phone calls. \x0d\ To sum up, the uneconomical and realistic complexity of SMS withdrawal and the unsupported hardware determine that SMS cannot be withdrawn.
