In general, unlocking doesn't just involve using special codes. You need to set different configuration parameters, including a list of preferred networks to connect if going to another mobile provider. Such as porting from Sprint to Verizon. It generally involves using specialized technician software to program the phone, and not user friendly for the average owner. Most will opt to use a service.
With all due respect, for the 4G GSM phone that I unlocked there was nothing to do other than insert the SIM from the new carrier. That instantly gave me voice service and SMS texting. To use the minimal internet browser built into the phone I did have to enter carrier-specific access point information and create a new internet profile for the phone, neither of which was all that difficult after the carrier's support staff told me where to find the information.
