What's the pin number of the mobile phone?

If you use a vivo phone, you can refer to the following:

PIN code is the personal identification password of SIM card, which is used to protect SIM card and prevent it from being illegally used.

After setting the PIN code, you must enter the PIN code no matter whether you shut down, restart or insert a mobile phone card.

If you enter the wrong PIN code for three times, it will automatically lock the card, which can effectively prevent others from changing their mobile phones, receiving short messages, and modifying passwords such as Alipay and WeChat.

The default PIN code is 1234 or 0000. If you change or forget the PIN code, please contact the staff of the operator to which the SIM card belongs.

The contact numbers of the four major domestic operators are: 10099 (China Radio and Television), 10086 (China Mobile),10 (China Unicom) and 10000 (China Telecom), so you can call them in time.
