How long is the validity of SMS as evidence?

Legal analysis: The time limit for giving evidence is stipulated by the court at the time of prosecution and will not be affected by the carrier of giving evidence.

To put it simply, if the court wants to hand in all the evidence within 1 month, it can only give evidence to the court within 1 month (of course, if it is really difficult, it can ask the court for an extension), which will not be shortened because it is a mobile phone text message, nor will it be lengthened because it is a documentary evidence.

Legal basis: Article 6 of the Electronic Signature Law of People's Republic of China (PRC) * * * A data message that meets the following conditions shall be deemed to meet the document preservation requirements stipulated by laws and regulations:

(a) It can effectively express the content and can be used at any time;

(2) The format of the data message is the same as that when it was generated, sent or received, or the format is different, but it can accurately represent the content originally generated, sent or received;

(3) Being able to identify the sender and receiver of the data message and the time of sending and receiving.
