Why do I need to unlock my cellphone?
Your LG A133 comes locked to the carrier that sold you the phone. For example, if you bought your cellphone from AT&T, it will only work with AT&T, and will give you an error as soon as you try inserting a simcard from a different carrier. Unlocking your phone will disable the lock and allow you to use your cellphone with any GSM carrier worldwide, such as T-mobile, Cingular AT&T, Rogers, Fido, and more.
