You can call the carrier you bought it from and ask for the code. If you have already paid for the phone by completing the original contract period, usually 2 years, they are legally obliged to unlock it for you.
Even if you have not, you are legally obliged to pay for the phone, even if you terminate service early, by the billing you will get from them for the cost of the phone you received for free or discount. So, you can use this argument if needed to get them to unlock YOUR phone. Be respectful and nice.

If you cannot get your carrier to unlock your phone, you can pay for the unlock code from many safe and legitimate web sites. Ebay is a good source for buying phone unlock codes because sellers compete for your business and the seller is rated by buyers of their products/services and won't risk displeasing you.
You buy the code, shipping is free via email, they send you the 15 digit unlock code via email, and you enter in into your phone. It's that simple. Note some phone models are not unlockable this way and must be done by your carrier. Just search on ebay for your phone model with the word 'unlock' and if it is unlockable, you will find a seller selling it.
