I bought 2nd hand LG K4 and inserted my Lucky Mobile SIM card that I currently use for Lucky Mobile and when I powered on the LG K4 phone before I can start to use the phone a screen pops up saying; "SIM network unlock PIN Unlock attempt 1 of 10"
Hi Tyrone. It looks like the previous owner tried to guess the network unlock code. Do you know which carrier the phone is locked with? You can contact the carrier and get an unlocking code for free.
