PIN You may need a PIN (Personal Identity Number) to activate the services in your phone. The PIN is associated with your SIM card, and not with the phone. Your PIN is provided by your network operator. When you enter your PIN, each digit appears as *, unless your PIN starts with the same digits as an emergency number, for example 112. This allows for emergency calls without entering a PIN. If you make a mistake while entering your PIN, delete the number by pressing . If you enter the wrong PIN three times in a row, the SIM card is blocked and the message "PIN blocked" appears. To unblock it, you need to enter your PUK (Personal Unblocking Key) % 74 SIM card lock. Battery Some functions use more battery power than others and may cause a need for more frequent re-charging.
