This SIM card unlocking post is presented by iToolab.

iToolab has released a new tool designed to quickly and easily let you unlock your iPhone or other smartphone’s SIM card and even switch cellular data carriers. This may come in handy when someone gives or sells you a second-hand phone and you realize it’s locked.

The process used with iToolab SIMUnlocker takes just 5 minutes to complete, does not result in data loss and permanently unlocks the device, the company says. And if you have any issues, its customer support staff “is always on standby.”

Note that the process involves jailbreaking your device, by which you remove software restrictions intended by Apple, in the case of an iPhone. As such, it’s always something to consider carefully before going ahead.

iToolab also makes a tool called UnLockGo.

The tool fixes common SIM card issues. For example, if you see a “SIM Not Supported” message indicating the card can’t be activated. Or if you insert a new SIM card and a “SIM Not Valid” message pops up. And of course, the card may be restricted by a service provider or its functionality limited during international travel.

iToolab: how to unlock an iPhone SIM card and use any carrier

The video below goes through the steps needed to unlock your iPhone SIM card and use any cellular data carrier, worldwide. This is especially useful in a situation where you run into a “SIM Not Valid” message. Each step is outlined a bit further under the video.

You can also find more information in iToolab’s user guide, How to Use iToolab SIMUnlocker to Unlock iPhone SIM Card. The page also includes video tutorials for using the tool with macOS or Windows.

Some notes before you start:

  • Unlock your iPhone’s screen.
  • If your phone is blacklisted, it’s not possible to unlock.
  • Turn off Find My iPhone before engaging SIMUnlocker.
  • Don’t try to use your device for anything else during the unlocking process, or it might fail.

STEP 1: Launch SIMUnlocker and connect your iPhone to your computer.

SIMUnlocker main interface

Unlock your iPhone screen first by entering the passcode. Connect your iPhone to your computer via USB. If your iPhone has not trusted your computer, click Trust to complete the connection. Then press Start.

Step 2: Jailbreak with the built-in Checkra1n tool.

Download jailbreak tool

Assuming you have a good network connection during the process, SIMUnlocker will automatically download the jailbreak tool Checkra1n. If your phone has already been jailbroken, skip this step. If not, click Jailbreak.

A Checkra1n box pop-up will request you fill in options to continue to install the jailbreak. Follow the prompts. If you don’t know what something means, it’s unlikely you need it, so you can skip it.

When prompted, click Start to have your iPhone enter recovery mode. When the process reaches Done and welcomes you to Checkra1n, you can close the pop-up window.

Step 3: Confirm your iPhone information and unlock.

Confirm your device information

After the jailbreak is complete, please confirm your device information, and then click the Remove button to complete the progress.

Step 4: Wait for the unlocking process to complete.
