How to reliably unlock your iPhone with the updated SAM tool

By , Apr 25, 2012

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.

    Sorry to say that after following the instructions to the letter, my iPhone4 did not unlock. I tried the simple route first and when it did not work I followed the extended method in the Troubleshooting section. In the end I continue to get the error message “Activation reports Error: ActivationInfo rejected. You must select the original carrier SIMID of your phone.”

    Does anyone have a suggestion?

    Ok so I’ve tried all the methods I can find to unlock my sprint iphone 4s to use with metro pcs but to no avail. I’ve got cydia, sam prefs and ifile and can’t get either to unlock this phone. My last option was to try the ifile option above and it still says (Activation reports error: Activationinfo rejected. You must select the original carrier SIMID of your phone.) I don’t have the original sim or ID so I’m beat ugh! Has anyone ever unlocked a sprint iphone 4s to use with metro pcs and if so how should I go about it? Your help is much appreciated thank you.

  • Done Diggity Do

    When i go into “more information” the “ativationstate” is just blank. It doesn’t say de-activated or anything like that. After following your steps it still said the error to select the carriers original SIMID, help!

  • slabs

    Don’t work for me can anyone help me? I do it more than one time but it says everytime : SAM Notification Activation reports Error: ActivationInfo rejected. You must select the original carrier SIMID of your phone.

  • Nataly Rojas

    It didn’r work for me :/ I have iphone 4s, it did change something though.. But its not working cant make calls or anything.. It doesnt say ” no service” anymore it just has the the little circles ..

  • Duc Su

    I’ve been away from the iphone latest new info. I’ve never knew about SAM until now, though it was been around for couple of years I see. Anyways, I am currently on a jailbreak iphone 4 running on ios6.1.3 with baseband preserved to use Gevey sim.

    I want to update to ios7.4 since it can be jailbreak. Doing so will update my baseband as well. Since there is no custom firmware I can use, will this SAM method work to unlock my iphone going to ios7.4 even if I never saved my tickets on this phone? I’ve read a post saying if you haven’t saved your ticket prior to 2012, SAM will not work.

  • Non-Specific Action Figure

    I’m trying and I can’t get my T-Mobile sim working on my Verizon iPhone 4s with 7.1.2.

  • Ashwin

    HI I did this and the earlier one too. After attempt activation it resprings and shows me the the signal strength full but cant dial anything except the USSD codes where you can see your balance for my Mobile number and data usage etc. In About section I can see the Carrier is changed but Network Not available.
    What could be the reason? I have tried all possible options from the tutorial as well as the tips. No break -through yet.
