Methods to query the International Mobile Subscriber Identity (IMSI) code mainly include using the USSD code of the device, contacting the network operator, using the system setting options of the smartphone, using professional mobile phone viewing applications, and using legal means to query through law enforcement agencies. Among them, using the USSD code is a quick and easy way to display the device's IMSI information by entering a specific short code into the device's dialer and dialing. The convenience of this method is that most mobile phones support USSD codes, and users do not need any additional applications or tools to query them.
USSD (Unstructured Supplementary Services Data) codes, often called "quick codes" or "signatures", are a protocol for sending information over the telephone network. Users can query the IMSI by entering a specific USSD code:

Enter some common USSD codes directly into the dialing application of your phone, for example: *#06# to query the IMEI number. Some devices may display the IMSI code at the same time.If the query using the USSD code fails, contacting the network operator is the direct way to obtain the IMSI code:
Contact your network operator's customer service and verify your user identity. Request information about the IMSI code associated with your mobile card or account.Network operators have detailed records and can generally provide this data after completing user authentication.
