Fix SIM Not Supported iPhone: Carrier Unlock Walkthrough and SIM Test

This tutorial demonstrates a carrier unlock walkthrough when you see sim not supported iphone messages after inserting another carrier's SIM. It starts by removing the SIM card and changing key settings under General, then uses a browser-based network unlocker that supports both iOS and Android devices. You choose your iPhone model and iOS version, enable the worldwide unlock option, and start the process without entering an IMEI. The video shows the confirmation popup and the waiting period, and notes that an extra plugin step is rare but covered separately if it appears. After the unlock completes, the iPhone is restarted and the target SIM is reinserted to verify the error is gone. Preparation includes having a SIM removal tool and knowing your exact device model and iOS version.
