Security for Your Phone and Subscription
Security for Your Phone
and Subscription
and Subscription
There are several ways to protect your phone and subscription from
unauthorized use. Anything from a SIM card lock to full phone number
control.
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.
