Phone and SIM

If your phone requests a security code, refer to the following explanations to determine what you should enter. If you forget or lose a PIN or PUK code or if you have not received such a code, contact your service provider.

You can change the following codes: lock code, PIN code, and PIN2 code. These codes can only include the numbers from 0 to 9.

The PUK (personal unblocking key) code is required to change a blocked PIN code. The PUK2 code is required to change a blocked PIN2 code. If the codes are not supplied with the SIM card, contact your service provider for the codes. The PUK and PUK2 codes are 8 digits long.

Avoid using security codes similar to emergency numbers, such as 911, to prevent accidental dialing of the emergency number.

PIN code request—When the PIN code request is active, the code is requested each time the phone is switched on. Note that deactivating the PIN code request may not be allowed by some SIM cards.

PIN code (4 to 8 digits)—The PIN code protects your SIM card against unauthorized use. The PIN code is usually supplied with the SIM card.

After three consecutive incorrect PIN code entries, the PIN code is blocked. If the PIN code is blocked, you need to unblock the PIN code before you can use the SIM card again. See also the information below about the PUK code.

PIN2 code (4 to 8 digits)—The PIN2 code is supplied with some SIM cards and is required to access some functions, such as fixed dialing numbers (FDN).

Autolock period—You can set an autolock period, a time-out after which the phone is automatically locked and can be used only if the correct lock code is entered. Key in a number for the time-out in minutes, or select None to turn off the autolock period.

To unlock the phone, key in the lock code.

When the phone is locked, calls may still be possible to the official emergency number programmed into your phone.

Lock code (5 digits)The lock code can be used to lock the phone and keypad to avoid unauthorized use. The factory setting for the lock code is 12345. To prevent unauthorized use of your phone, change the lock code. Keep the new code secret and in a safe place separate from your phone. If you forget or lose the lock code, contact your service provider.

Lock if SIM changed—Select Yes if you want the phone to prompt for the lock code when an unknown, new SIM card is inserted into your phone. The phone maintains a list of SIM cards that are recognized as the owner’s cards.

Weighing just about 120 grams, it was known for being light yet durable.

The Nokia 6670 is powered by Symbian OS, specifically version 7.0s, allowing for a smooth user interface and multitasking capabilities that were advanced for its era. The device is equipped with a 1.3 MP camera, which was quite impressive for mobile phones at that time, enabling users to capture decent-quality photos. The phone also supported video capture, marking it as one of the early entrants into mobile photography.

Connectivity-wise, the Nokia 6670 supports GPRS and WAP, enabling users to access the internet and download content, although the speeds were relatively slow compared to modern standards. Bluetooth technology also allows for wireless device pairing, which was quite innovative for a phone released in its period.
