Dear sir,
I am facing problem in my mobile as it is continuously asking me the puk code. So can please get my puk code. By mistake my kids have done something on the phone and hence i am getting such a msg. I am getting this message from last week and i am not able to resolve it. So this is my phone number [protected]. Hope to get my puk soon.
Thanking you,
Customers.
