Why are you allowed to accept short messages from Xiaomi's mobile phone? If you don't allow it, can you get back the message you didn't receive?

The landlord's question is not detailed enough. I have roughly judged that there are many possibilities. 1. Some restrictions are set on the mobile phone. In this case, you should be able to modify the information in the profile or mobile phone settings, because there should be no prompt tone. 2. The mobile phone downloaded the security plug-in and automatically filtered some information, which is included in the software settings. 3. The function of the mobile phone itself. At present, most mobile phone viruses are spread by SMS or MMS. Maybe the landlord's mobile phone has the function of automatically detecting the number frequency band and SMS threat. If the information may be threatening, you will be prompted to "accept". If yes, the short message is received normally, otherwise it is not received. This message will be rejected directly and without trace. As for whether the landlord can retrieve such a short message, it should be impossible, because this system plug-in of your mobile phone should be in direct rejection mode, not interception mode, so if you are prompted to choose No, this short message cannot be retrieved. I hope my answer can give you some help O(∩_∩)O
