iToolab SIMUnlocker does exactly what its name implies. This means that if you are having trouble with a carrier-locked iPhone, this tool can help you fix it. It works with devices that feature iOS 12 all the way up to iOS 14.7. Apple products such as iPhone X, Eight, Seven, Six, and Five qualify successfully for the SIM unlock procedure this program conducts. The whole process will unfold in front of your eyes on account of the user being guided every step of the way.

While the interface looks modern, as we've come to expect from these types of tools, the app itself doesn't really hold a lot of options and settings. In fact, the few buttons displayed in the window are usually external links to documentation and other app-related stuff. The developer has also included an online tutorial for understanding how the procedure unfolds before actually starting it.

You will be required to tie your iPhone device to a PC that has this software installed. The program will then attempt to recognize the device. Once the handheld is found by the app, you'll have to follow each step carefully, executing the tasks outlined by the program. The app will do its magic, unlocking the phone for use with any SIM carrier you might like or need.
