Hello to all, I am in big trouble that my SIM has been blocked and I want to have the PUK number of my SIM card. I know my PIN code but I have forgotten my PUK number. When I tried to update the PIN it didn't work so now it wants the PUK number. I entered the code three times and every times it says it is invalid and now it is block, now it is asking for the PUK code. Please kindly help me to find solution for it.
