What is Netlock?
This particular type of locking an iPhone restricts the usage of SIM-cards that do not fit the designated network. If the net lock applies to, for instance, Verizon, you will only be able to use SIM cards which connect to the Verizon network. This type of lock can be achieved with a certain software. Usually a net lock is valid for about 2 months or until the providers fee to unlock the smartphone is paid. As soon as the netlock is lifted, all SIM cards can be entered.
Check if your iPhone is locked or unlocked
Quick method
The simplest way to check if your iPhone has been locked by the provider: Put in another SIM card. Your iPhone will show an alert “SIM not Valid” or “No SIM”, if the locked status prevents usage. Another common error message is “The SIM card inserted in this iPhone does not appear to be supported”. Double-check the SIM for visible damage, dirt or surface irregularities, as these can also cause the “No SIM” warning.
Web method
You can also use a web service to determine whether your desired iPhone is locked, factory locked or has been locked down by the provider. Websites such as imei.info offer a lookup service and only require the IMEI number.
How to get the IMEI on iPhone: You can find the IMEI number at the back of your device, also see our guide for checking the IMEI on iPhone. Another way to retrieve your IMEI number, e.g. if the back of your iPhone has been scratched and is affecting the legibility of the number, is to input a special GSM code in the dialer of your Phone app. Enter“*#06#” without the quotes and iOS will display the IMEI for you. A further way to check the IMEI would be to launch iTunes with the device connected to a Mac or a PC.
Once you have it, simply enter your IMEI number at imei.info and click “SIMLOCK & WARRANTY” to proceed. You will have to register for a free account, though. The website will return detailed information on the status of your device and whether a simlock or carrier lock is likely.

Whether you’re buying a new or pre-owned iPhone, it’s a good idea to take a look at whether it’s locked or unlocked. This can have a big impact on what mobile carrier you’re able to connect with as well as the price you pay for your new phone.
You can’t tell just by looking whether your phone is unlocked though, which is why we’re here to help you check on the status of your iPhone before you buy it.
Have an iPhone that is locked to a carrier and don’t have any options to unlock it to choose any carrier? We have an guide that analyzes the safest and most reliable unlocking services to consider. Read this.
What is an Unlocked iPhone?
The lock is essentially a software code that’s put on the iPhone by the manufacturer to meet operator requirements, attaching the iPhone to a carrier. This means that an unlocked iPhone is a phone that isn’t limited to a particular carrier.
You can switch your phone from one network to another and it will still work just fine. Usually, iPhones bought directly from Apple will be unlocked.
If you buy your phone used or from a specific carrier though, the phone is generally locked until the contract is completely paid off, or until the previous owner’s contract is paid off.
Since iPhones are not branded by specific mobile carriers, you can’t determine the carrier just by looking. You’ll have to check whether the iPhone is locked or not if you’re buying and would like to switch your carrier.
How To Check If iPhone is Unlocked
Unlocking your phone is important if you’d like to change carriers, which is why many people like to perform this check on the iPhone before they buy one.
You have a few different methods you can choose from to perform this check, the simplest one being the SIM card check.
Is My iPhone Unlocked – SIM Card Check
All you have to do is take out your iPhone’s SIM card and put one in for a different carrier. Make a phone call using that SIM card and see if it connects. If the phone call doesn’t connect, then the iPhone is locked.
You can try this method easily if you have a friend using a different carrier for their phone, although not everyone has a SIM card readily available to them.
You might be able to walk into a store for a different carrier and ask to borrow a SIM card though.
This might not work for all other carriers, but some are very accommodating and will simply hand you a SIM card for a few moments. It should only take a few seconds to have your answer.

Head on over to your Settings app and tap into the Mobile Data and Mobile Data Options. Check to see your Mobile Data Network – if you see the option for your network, this means that your phone is unlocked.
If you do not see the option, it won’t appear on locked iPhones. This isn’t completely effective though and should be double-checked.
Call Your Carrier
This solution is a bit more difficult and may not always work, since carriers do not always tell you whether the phone is locked or unlocked over the phone. However, it’s the surest way for you to know the status of your device.

You can also find the IMEI number by connecting your phone to your computer and launching iTunes. Just go to Device Summary and click on the phone number.
You also have the option of checking your device’s original packaging and barcode, or even looking at the SIM card tray in some cases.
