How to Check If iPhone is Unlocked with/without SIM Card

Choosing to purchase a second-hand iPhone is an affordable way to get your hands on a great device. Before buying a used iPhone, it is important to determine if the device is unlocked or not.

In this guide, we will share with you how to check if iPhone is unlocked with or without SIM card. Also, you will learn what to do if your iPhone is locked.

What Is A Carrier Locked iPhone?

This is one of the most common types of lock problems that most iPhone users contend with. Simply defined, a carrier locked iPhone means that the carrier you choose to use has imposed a lock on the device. And you may not be able to insert a SIM into the device unless it is from the network imposing the carrier lock.

Therefore, for the length of the contract you have with that network, you will only be able to use that carrier's SIM card. Some carrier locks will even extend long after your contract ends or even when you cancel the contract. When you insert a new SIM card into the iPhone, and the device is carrier locked, you will see "SIM No Supported" or "SIM Not Valid" on the screen.

Fortunately, there are four effective ways to check if the iPhone is unlocked with or without SIM card:

How to Check If iPhone Is Unlocked without SIM Card

If you don't have another SIM card that you can use to check if the phone is unlocked, the following are just three of the most effective alternative solutions you can try:

#1. Check If iPhone Is Unlocked via IMEI (100% Accurate, Not Free)

The license plate that your iPhone has is IMEI, which can identify the device unequivocally worldwide. If you know your IMEI, there are online IMEI checking tools such as DirectUnlocks that can help you determine if the iPhone is unlocked. However, you may need to pay a small fee for it. Here's how to use DirectUnlocks:

  1. Fist, you should get the IMEI serial number of your iPhone. Check our guide to find the IMEI number on iPhone/iPad.
  2. Go to DirectUnlocks Network check service page on any browser of your computer.
  3. Enter the iPhone's IMEI number in the box provided and then click on "Continue".
  4. Follow the on-screen instructions to pay for the service. Once the payment has been processed, DirectUnlocks will show you your iPhone's lock status.

#2. Check If iPhone Is Unlocked via Settings (Not Work for All iPhones)

You may also be able to check if the iPhone is unlocked from the device's settings, follow these simple steps to do that:

  1. Open the Settings on your iPhone and then tap on "Cellular".
  2. See If you can find the "Cellular Data Option" in this menu. If you see it listed then the iPhone is unlocked, but if the option is not there, then the device is locked.

NoteNote
Sometimes this setting may not be available in certain iPhone models or iOS versions even if the device is unlocked.

#3. Check If iPhone is Unlocked by Contacting Support (100% Accurate, Lengthy Process)

Perhaps the best way to find out if your iPhone is locked or not is to contact your carrier's support. You will be able to find their contact details on their website or on the contract you signed with them.

When you contact them, be clear about what you want to know and provide as much information about your account as possible. They may require you to provide some security information since the contract is a legally binding document. This process may therefore take some time, but it is the most effective way to check if the iPhone is unlocked or not.

How to Check If iPhone Is Unlocked with SIM Card

Perhaps one more accessible way to check if your iPhone is unlocked is with the SIM card. Simply by inserting a different SIM card, it will show you whether the iPhone you have is locked or not. The following are the specific steps to do that:

  1. Begin by checking if the iPhone has a connection to the carrier and then turn off the device.
  2. Use the SIM card removal tool to remove the SIM card on the device and then insert a different SIM card into it.
  3. Now check the carrier connection and then try to make a phone call. If the call goes through, then there is a good chance that the iPhone is not locked.
