What should I do if my new SIM card receives strange messages frequently?

Reason: The number you used was set by others to prevent the phone from being lost. Simply put, for example, your mobile phone has an anti-theft software, and you can set several numbers in the software. If the mobile phone is lost, once the person who finds the mobile phone inserts the card, his number will automatically send a warning message to the phone number you set before, and you can trace this phone number to find the lost mobile phone.

Solution: 1: Go to the mobile business hall and you should be able to cancel all the information before this number.

2. Can you find someone who has set up anti-theft tracking for this number, and he can cancel your number?

Hold on for a while, when his software is not used, he won't send you a message automatically. ...
