SIM card lock

phone itself, from unauthorized use. If you change SIM cards,
the phone still works with the new SIM card. Most SIM cards
are locked at the time of purchase. If the SIM card lock is on,
you have to enter a PIN (Personal Identity Number) every time
you turn on your phone. If you enter your PIN incorrectly three
times in a row, the SIM card is blocked. This is indicated by the
