You can protect your phone against unauthorised usage by activating the Phone Lock and/or SIM Lock function(s). All mobile phones have these security setting features.

1.       Phone Lock:
By activating this function, you will be prompted to enter a PIN code every time the phone is switched on.

To activate Phone Lock:
You may refer to your mobile phone user guide under 'Security Settings' and set the PIN code accordingly. Should you forget your PIN code number, you will need to visit the respective mobile phone service centre to reset the PIN code.

2.       SIM Lock:

This function enables you to protect the SIM card with a PIN. The default PIN for SingTel SIM card is 1234. Once the PIN is activated, you will be asked to enter the PIN each time the phone is powered on. If a wrong PIN is entered incorrectly for 3 consecutive times, the PIN will be locked from further access. SingTel will have to be contacted to obtain the PIN Unlock Key (commonly known as the PUK).

To activate SIM Lock:
You may refer to the mobile phone user guide under 'Security Settings' and set the PIN Code accordingly. Please note that the PIN security feature is turned OFF initially. The default PIN is programmed as 1234.

To change PIN:
You may refer to your mobile phone's user manual OR you can do this manually by entering the following: **04***#

3.       Taking note of your IMEI number:

You may take the extra step of taking down the International Mobile Equipment Identification (IMEI) number. The IMEI is a 15-digit number unique to each mobile phone. You just need to key in *#06# on your mobile phone to access the number. This is to facilitate the Police's efforts to track lost/stolen mobile phone by the police should you lose your mobile phone.

We understand the Police's efforts to:

• Conduct spot checks on phone users to check a phone's identity number against a database they have on lost or stolen phones.
• Compile a database of stolen phones using the 15-digit IMEI number. This database is expected to be made available online in 2006.  

4.       Back up your SIM/Phonebook:
Previously if you lose your mobile phone, all the data and phonebook entries that you have stored in your SIM card would be lost too. With SingTel's  Phonebook backup service, your SIM card's phonebook entries will be uploaded onto our database. So even if you lose your mobile phone, you can retrieve your previously stored phonebook entries. In addition, our Backup SIM Card service enables you to backup your SIM card data in a spare SIM. If you lose your mobile phone, you can activate your Backup SIM card and use it immediately on another phone.
