The mobile phone received a strange text message. Some people say it is located. Can you translate it for me?

Cell identification number: 7403; Location area code: 8505; Country code: 460(460 stands for China); The network operator code MNC 0 2 indicates the status of ChianUnicom: 1 is a piece of location information. Maybe another SIM card is installed on your mobile phone after the anti-theft software is turned on. At this time, the mobile phone will automatically send you location information. You can also call customer service to inquire about any additional services you ordered, and then cancel. Or your acquaintance set the anti-theft number of the mobile phone to your number, and the above situation happened on his mobile phone, so you will receive these short messages, and there is no specific location!
