Hello i have china phone i9++i model in security set up sim2 it was asking puk2 pl send the puk2


Hi,

The easiest way to get the PUK code is to call your service provider, such as T-Mobile or Verizon. They need to verify your cell phone number and your IMEI number and they will provide you with the PUK code.

Hope this helps,
Joe
