Part 1. Something You Need to Know before iPhone Unlock Check

1. What Is a Carrier Locked iPhone?

When you sign up for a phone contract, according to the carrier you choose, you will get a carrier lock, preventing you from inserting a SIM card not from them. It affects you nothing since you need the original SIM card for the contract's benefit.

However, if you cancel the contract halfway or it naturally ends, you won't insert a new SIM card into your iPhone unless it is from the same carrier. Moreover, some carrier locks are even more confining not to accept any other SIM cards except the original one.

Therefore, when you put a SIM card into a carrier-locked iPhone, it will display "SIM Not Supported" or "SIM Not Valid" on the screen.

2. Why Does Carrier Lock My iPhone?

Generally, the iPhone is unlocked if you purchase it from Apple Store at a lump sum. However, if you get it from a network, the carrier may lock it only to use the carrier's SIM card during the contract. And when the contract is due, it will unlock your iPhone then.

3. What Is the Difference Between Locked and Unlocked iPhone?

First, a locked iPhone only works with the carrier where it has been purchased, while an unlocked iPhone works with any carrier, and you don't need to do anything to use a different cellular carrier. Second, an unlocked iPhone costs more than a locked iPhone since you have to order it from Apple Store at full payment.

4. How Do I Know if My IMEI Is Unlocked?

The only way to know whether your iPhone is IMEI unlocked or not is by using an IMEI checker, which will also tell you if the IMEI number is clean. If the IMEI number is not clean (i.e., stolen or lost), your iPhone won't work for any network.

5. How to Tell Which Carrier Is On if There Is No SIM Card?

Go to Settings > General > About and find Carrier, then you will learn which carrier is on your iPhone.
