Wondering whether that iPhone you plan on buying off of craigslist is truly unlocked like it says in the ad? Want to make sure that your iPhone is able to switch carriers after a legitimate unlock from your current carrier? Grab your iPhone and open a new web browser window; we’re going to show you how to find out.
First up, you’ll need to get your iPhone’s IMEI number. Launch your Settings App, and tap on General. Then tap on About, and scroll down to where it shows your 16 digit IMEI number. You can also dial *#06# on your iPhone or any other mobile device to get your number.
Next, head over to IMEI.info and type your IMEI number in there, all 16 digits, without any spaces or dashes. Then click on the CHECK button. You’ll get a page similar to the screenshot above, with information about your iPhone: Model, Brand, Design, Memory, etc.
Scroll down a bit further, and click on the Free simlock status check button there, so you won’t have to log in with Facebook or anything. The resulting web page will tell you whether your iPhone is locked or unlocked as well as the expiration date of your current Warranty. Pretty cool, huh?
Now you can be sure that any seller of an unlocked phone is telling the truth: simply ask them for the device IMEI, or–better yet–get it from the device yourself and plug it into this handy website.
