How to reliably unlock your iPhone with the updated SAM tool

If you haven’t had much success unlocking your iPhone with the SAM tool, then perhaps this will be of interest to you.

The developer of the SAM tool has updated it to make unlocking much easier than before. In fact, it only takes a few steps in most cases.

You don’t need iTunes, you don’t need the original SIM that you device is locked to, SIM ID’s, or anything like that.

Check out our full how to inside…


Step 1: Install SAM via Cydia. Repo address:

Step 2: Insert your unofficial SIM card.

Step 3: Open SAMprefs, Go to Utilities and tap Attempt Activation.

Step 4: Your device will respring, and it should recognize your unofficial SIM card. If this doesn’t work, follow the full tutorial outlined below, and in the video.


If you receive a message that says: You must select the original carrier SIMID of your iPhone, or any other error message, simply perform the following:

Step 1: Remove your SIM card

Step 2: Open iFile and go to /var/root/Library. Tap edit in the upper right-hand corner, and select Lockdown, and tap the zip button to create a backup of Lockdown. Scroll to the bottom to ensure that a backup zip was created. Now delete the Lockdown folder.

Step 3: Navigate to /User/Library/Preferences and search for SAM. Delete the com.bingner.sam.plist file.

Step 4: Power down your iPhone completely, and turn it back on.

Step 5: Insert your unofficial SIM card.

Step 6: Open SAMprefs go to Utilities and tap Attempt Activation. You will receive a dialogue stating that it may take a while. Your iPhone will respring.

Step 7: You should now be on your unofficial network. i.e. T-Mobile, etc.

Be sure to follow these steps exactly in order for it to work. I’ve tried this nearly a dozen times, and it always worked for me. For more info on unlocking, be sure to check out our dedicated unlock page.
