How to Check If iPhone Is Unlocked with/without SIM Card?

“Recently I planned to buy a second-hand iPhone, there are so many people suggest me getting an iPhone that is unlocked. But the question is, how do I know if my iPhone is unlocked?”

Buying a second-hand iPhone enables you to use it at a lower price. It’s very important to know if it is unlocked before purchasing. If you plan on purchasing an old iPhone or already have an iPhone but don’t know the status of it then find out how to check iPhone unlock status by reading this guide.

Before learning how to tell if your iPhone is unlocked, you need to learn how the carrier lock works.

Part 1. What is a Carrier Locked iPhone?

When you sign up for a phone contract, depending on which carrier you choose they could impose a carrier lock. There’s more than one type of lock but the most common is a network carrier lock which prevents you from inserting a SIM card which isn’t from them.

For the length of your contract, this won’t typically be problematic or inconvenient since you require the original SIM card for your contract’s benefits. However, if you cancel the contract or it ends, you won’t be able to put a new SIM card into the iPhone unless it is from the same carrier. Some locks are more restrictive, and the iPhone might only accept the original SIM.

When you insert a SIM card into a carrier locked iPhone, it will show “SIM Not Supported” or “SIM Not Valid” on the screen.

Luckily, after trial and error, here are 4 ways to learn how to check if iPhone is unlocked that we found.

  • Check with SIM card: 80% accuracy, but this way won’t tell you which carrier your iPhone is locked to
  • Check with online service: fast & 100% accurate, let you know the particular carrier that your iPhone is locked to. But it’s not free (will take $3)
  • Check in Settings app: fast & easy, but it doesn’t work for specific iPhone or iOS versions
  • Contact support: 100% accurate, but it’s a lengthy process

Part 2. How to Check if iPhone is Unlocked with SIM card?

Let’s talking about the easiest way to check it – using an SIM card.

Simply inserting a different SIM card will give you an idea of whether or not you’ve got an iPhone lock, and this is how.

Steps to Check iPhone Unlock Status with Different SIM Card

Step 1. Check that your iPhone has a connection to the carrier. Then power off your iPhone.

Step 2. Using a SIM removal tool, take out the current SIM card. And insert the different SIM card and turn on the iPhone.

Step 3. Check the carrier connection again and try making a phone call.

Tip

If you’re able to make a phone call then that’s a good indication that there isn’t an iPhone lock.

This can be a quick way of gauging if a lock is in place, although the results are not always reliable since the lock type could also apply to the SIM you insert.

Part 3. How to Check if iPhone is Unlocked without SIM card?

Don’t have a SIM card? Fear not, here 3 ways to check iPhone unlock status without SIM card:

3.1 Check If iPhone Is Unlocked with IMEI

If you don’t mind paying a small fee, discover how to tell if your iPhone is unlocked by using an online service. These services only require a few generic details about your iPhone and although they charge a fee, it saves you going through the hassle of finding out if there’s a lock by yourself.

One of the most popular online checkers is WipeLock iPhone Carrier Checker, and these steps will show you how to use it.

Step 1. Open an internet browser and go to WipeLock iPhone Carrier Checker page.

Step 2. Click on “Submit IMEI” and type your iPhone’s IMEI number into the box below.

Step 3. Pay for this with Paypal.

After making payment, the expert will alert you of your iPhone’s lock status via an email. Here is an example result:

For just a few dollars, and with minimal effort, an online service is the best way to check iPhone unlock status.

3.2 Check iPhone Unlock Status via Settings

A quick look through your iPhone’s settings will also prove useful to tell if your iPhone is unlocked. Here is how you can check it:

Step 1. Unlock your iPhone and launch the “Settings” app.

Step 2. Tap on “Cellular”.

Step 3. Look for the “Cellular Data Option” on this menu.

Tip

  • If the option is listed, then your iPhone is unlocked and you can change the carrier network it connects to freely.
  • If this setting isn’t available, then it is locked.

Bear in mind that some iPhones, and iOS versions, will not display this feature in which case this is not an effective way to check your iPhone lock.

3.3 Check If iPhone is Unlocked by Contacting Support

If you want to find out quickly or you don’t get anywhere following the solutions above, you can simply call your provider and inquire. Typically this is a detail you can find on their website or in the contract you signed.

Step 1. Call your carrier’s support team.

Step 2. Request that they check if your iPhone is locked.

Step 3. Provide account information for them.

Since this is information regarding your contract (a legally binding document), the support specialist will probably ask you some security questions. Overall this is a lengthy process to find out a relatively simple detail about your iPhone, but it’ll get you the answer.

Part 4. What to Do If My iPhone Is Locked?

Once you’ve gone through the solutions above, you might find out that your iPhone is indeed locked which would limit how you sell it. To circumvent this you can once again use DirectUnlocks and remove the iPhone lock.
