There are two pieces of information about the management card 1 in the advanced settings of Huawei Glory SMS. What is the displayed garbled code? Can it be deleted?

Hello, landlord, if the landlord's mobile phone is a dual-card dual-standby model, then in the settings, you should see the SMS on the card 1 in the SMS settings. Your information may be stored in a SIM card or mobile phone. In fact, no matter where it is stored, the information files in the mobile phone must be read, and other files in the mobile phone should not be read. This information should be in the saved information folder. As for the specific reasons for the garbled code, it may be that the reading failed, or there may be something wrong with the short message itself, which led to the reading failure. But deleting it should not be a problem.
