Why can’t I use another SIM Card on my iPhone?

Most carriers (like T-Mobile, AT&T, Verizon, etc.) restrict the devices they sell in an attempt to keep their customers using their network and offer better deals to lock you into a contract.

Those SIM restrictions can be enabled in all cellular devices and can only be removed with an iPhone SIM unlocking code (when you see the error message, you enter the iPhone SIM unlock code and then force restart) which can be obtained directly with the mobile carrier or with an alternate unlocker.

This carrier or network lock does not affect the iPhone’s functionality, so most iPhone users find out the phone is locked when they try to use a different SIM card (one from another network provider) and see the SIM card not supported screen.

However, there is a way to confirm if an iPhone is locked or not (you just have to look at the network settings of the iPhone), here we will explain how.

How to Confirm if I have a Locked iPhone

Go to the Settings of your iPhone
  • Go to the settings app of your iPhone.
  • Go to “General” and then click on “About”.
  • Scroll down until you see the “Carrier lock” tab.

If the iPhone is unlocked, you should see a message saying “No SIM restrictions”. Now, if you see this message yet are still having the “SIM not supported” issue, you can force restart on the iPhone — to reset the carrier settings — and try again (if it doesn’t work, you probably need the iPhone SIM unlocking code).

Why do I need my IMEI Number to Remove the “SIM Not Supported” Error?

Every mobile phone including Apple devices have an IMEI number (regardless of the iPhone model), this number is a unique code used to identify cellular devices and is, therefore, used by mobile carriers to lock every new iPhone (because that’s how they know which device is locked or unlocked, it works like an ID but for phones).

An IMEI number also contains important device information (like its manufacturer, its operating system version, etc.) that determines the appropriate unlocking procedure that should be used to bypass the “iPhone SIM issue”.

That is the reason why you are asked for the IMEI number when you want to start a SIM not supported bypass process (no matter if you do it with the carrier directly or by using third-party unlocking services like UnlockMaker). If you don’t know how to find your IMEI number, here are the easiest methods.

How to Find my IMEI number?

  • Verify if it is printed on your iPhone’s SIM card tray, in the original box in which it came in, or on the back of the iPhone (right next to the Apple logo appears the IMEI and Serial number).
  • From the dialer, type the code *#06# as if you were going to make a call, and you will see a black screen showing the IMEI of the iPhone.
  • Go to your iPhone’s Settings >> General >> About. You should be able to see the iPhone’s IMEI number.
