Why is the service password of the Unicom 2g card I bought always wrong, and I can only log in with the instant messaging password? Why?

Dear Unicom users:

You can edit the short message "MMCZ+ original password+new password+new password" to 100 10 to modify the password. If not, I suggest you use your ID card to modify the service password in the local business hall.

If you have any other questions, please call the local customer service hotline 100 10 for consultation.
