How does Unicom check the PIN code in the online business hall?
In order to protect the use of mobile phones, Unicom mobile phone cards are equipped with PIN codes and PUK codes for protection. The initial password of PIN code is 1234. When the PIN code is entered incorrectly for three consecutive times and locked, it can be unlocked with PUK code. Warm reminder: After inputting the wrong PUK code for 10 times in a row, the SIM card will be invalid and needs to be reissued. You can log on to the online business hall/homepage and click self-service. After entering, click the villain icon in the upper left corner to display the PUK code information of the mobile phone number. You can also log in to the mobile phone business hall or contact the local manual service for inquiry.
