Security for Your Phone
and Subscription
There are several ways to protect your phone and subscrip-
tion from unauthorized use. Anything from a SIM card lock
to full phone number control.
The SIM Card Lock
The SIM card lock only protects your subscription and not
your 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 the 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 message PIN
blocked. If this happens you need to unblock it to access
your subscription.
