- 1). Contact the customer service department of your network carrier, and submit a request for the unlock key code. The company representative will ask you the reason for unlocking. Tell him that you are traveling overseas and would like to evade the high roaming charges.
- 2). Search for an unlock code generator website. For many older cell phone models, especially Nokia handsets, you can find free code generators on the Internet. Some of these websites includes Unlock it Free, GSM Liberty and Unlock.Nokia Free.
On these websites, you have to select your cell phone model and provide the phone's IMEI number. Once you submit these details, the website will show you a series of unlock codes that you can try on your phone--not all of them are guaranteed to work on your particular phone. The method of entering the code into the phone varies greatly depending on the cell phone model and the manufacturer. Nonetheless, you will get the unlocking instructions along with the code on the website. - 3). Go to a pay site that provides guaranteed unlock codes in exchange for a fee. Some of these websites include Unlocking, GSM Evolution and Unlock it Now. On these websites, you have to provide the phone's IMEI number, name of the network it is locked to, your name, email address and your credit card details. Within 24 to 48 hours, you should receive the code via email.
- 4). Insert a not-accepted SIM into your phone and power it on. When the phone asks for a code or a key, enter the unlock code obtained from the website. After entering the accurate code, your phone screen will show you the message "SIM Restriction Off."
