Check iPhone Carrier Lock Status By Model or IMEI Numbers

Check iPhone Carrier Lock Status By Model or IMEI Numbers before buying

This article was written to share with all you how to check iPhone carrier lock status by either using the model or IMEI number of your device. However, let me clear this with you that this is not to promote nor encourage any out-of-the box activities like unlocking your iPhone or any of your Apple devices – it’s entirely up to you if you want to. The main purpose why I’ve written this article on how to check iPhone carrier lock status is because most of us consumers don’t know if the iPhone or any Apple devices we are buying are stolen or locked by a certain local or International carriers. Most especially if you are buying the iPhone from someone you don’t really know or from an un-authorized seller of Apple products. This is just another precautionary step for you to protect you from people who wanted only your moolah or money.

There is nothing for you to download from the listed tools below. These are all online tools to help you check iPhone carrier lock status. And all you need is either the model number or IMEI number which is in the iPhone you are about to purchase. You can check from my other article (How to check if iPhone is original or fake) on how to get the serial number or IMEI number of your iPhone. Or simply go to Apple Support page to check your device’ serial number and/or IMEI.

Check iPhone Carrier Lock Status With Free Online Tools

The links below are not sorted in any ways. They were randomly picked for you to try.

1. – This is one of the online unlocking tools available for AT&T, SFR France, O2 UK, Bouygues France and many others carriers. However, one of their online free tools is the iPhone checker which includes the information if your iPhone is locked by a certain carrier. All you need to type or input is the iPhone’s IMEI numbers. - Check iPhone Carrier Lock Status if Locked

2. – Probably this is one of the popular Free iPhone Unlock Checker and also a great tool to check whether your iPhone is SIM locked or not. You only need to input your IMEI number and submit it for analysis. After it checks your IMEI against their IMEI database then it will display the information you will be needing – and that is if your iPhone is locked or not. - A Free iPhone Unlock Checker

3. – Among all of the links I have mentioned, I guess this is the best that serves its main purpose and that is to simply tell me whether my iPhone is locked or not and by which carrier. All you need to input is your iPhone’s model number which can be found at the bottom part of your iPhone’s box. If you happened to lost the box, you can go to your iPhone’s Settings > General > About then scroll down until you see the “Model” information. - Check your iPhone is SIM locked

4. IMEI.INFO – Like the first one I have mentioned this is yet another online tool that can find out information about your iPhone by just providing the IMEI numbers. One of the drawbacks now is that most of their tools are now PAID services. So this is probably one of the least online tools that I would recommend to you.


You can actually try all of them to to check iPhone carrier lock status and get the consistency and confidence you need before buying the iPhone you wanted from someone whom you don’t know. If possible, please ask your seller to provide the EMEI or serial numbers before you meet. And if you happened to bumped into a locked iPhone and you wanted to unlocked it, you can order it from some of the online sites I have mentioned or here in MANILA, Philippines, Greenhills is the best place to scout for someone who can unlock your iPhone. The price ranges from Php 2,500 to Php 3,500 or higher. It depends on the unit you are using.

  1. I was unaware of this method. Thanks bro for sharing this method, btw how to get the imei number for iphone. Thanks in advance.

  2. I’m not too comfortable with online free unlocking tools,
    i don’t like hacks on a legitimate registered phones, maybe it would disrupt some settings or wears off it’s warranty or something?
    plus can’t trust unknown sources with this !!
    why not just take it to the carrier directly ?
    can’t the carrier unlock it ? it should be free too!
    Don’t trust everything on the internet!
    Many thanks and Best wishes!

    1. HI Mtich, as I’ve mentioned on my post I am not here to promote these website but rather to use them as a tool to check if the iPhone people are buying from suspicious people or store are original or fake.

  3. i have iphone 5, is there any possible to unlock my phone but when i check the carrier it say UNKNOWN
    and what is the best way to unlock this

  4. Hi,

    Thank you for share.
    Almost site in this article can not check my iPhone 6 but work with me. That give correct carrier name and simlock, include manufacturer date and factory. That’s perfect. I hope that help people.

  5. Also include this to your list:

    Softbank Japan
    MD258J/A – 64GB (iPhone 4S)
    MD663J/A – 64GB (iPhone 5)

    My mom is using that 4S unlocked by X-SIM, and my iPhone 5 is unlocked by R-SIM 🙂

  6. Hey Arsie!

    Thank you. You have been a big help. Im planning to buy on one of the shops in greenhills tomorrow for an iphone. Actually I have done my research and so far, they don’t have any negative feedback, only good ones. But hey, like what you said, it isn’t paranoia. Its just to be sure that we don’t end up doing the old filipino saying: “NASA HULI ANG PAGSISIS…

  7. That’s cool that you can use online services to check the lock status. It would be good to check that before you buy a used phone. If it is unlocked, is there anything else you need to do before you can add the phone to your mobile carrier?

  8. Can you take me how to use find my phone .. One of my lost his iphone recently we used that find my iphone we didnt find any response from that

  9. What if my model can’t be identified where is it locked? Itried all the imei checker on where my phone is locked but it says unknown or error 🙁
