Most SIM cards are supplied with a security code, also known as PIN
(Personal Identity Number), which you need to access the network. Every
time you turn on your phone, you are asked to enter your PIN. You will find
your PIN in the information from your operator.
Some operators may have services that require a second PIN, your PIN2.
You should be careful with your PIN, since it is your protection against
unauthorized use of your subscription.
If your PIN is entered incorrectly three times in a row, the SIM card is
blocked. If this happens, you can unlock it by using your PUK (Personal
Unblocking Key code), which you also get from your operator.
Your T28 comes with a lithium battery. The battery is not charged when you
