Despite what many people believe unlocking and jailbreaking are not the same thing. While there are similarities, they both comprise key fundamental differences. A jailbreak makes way for unsigned code to be added to the iOS software, whereas unlocking is just allowing any SIM card to be used on a particular device, which has been previously cut off from the device carrier.

The carriers usually do open up these ports once the smartphone ages a bit, giving users a chance to unlock their devices. However, not everybody gets this benefit, and this leads to there being still a high demand for these guides on how to unlock.
