Received Unicom SMS: Dear contract customer, as of the 20th of this month, it was detected that your mobile phone was separated from the user number card, please.

It is stipulated that you can stop the machine, but generally you don't stop, that is, you don't refund the phone bill. In order to avoid losses, I suggest you contact your local Unicom and ask how to handle this situation. For example, in Tianjin, if you lose your mobile phone, you need to issue a certificate from the police station, and then apply for rebinding in the business hall before you can refund the phone bill.
