Happy with your iPhone, but want to switch providers? Perhaps you don’t like their customer service, or the tariff isn’t right for you. Whatever your reason, switching iPhone network providers has some huge benefits:

  • Save money and get better deals on tariffs
  • Keep your old mobile number
  • Perfect for travelling, especially when switching SIMs

Before you can enjoy the benefits of switching networks, you’ll need to check whether your current iPhone is locked, then unlock it.

Some iPhones are easier to unlock than others, depending on the network service provider. Newer iPhone models like the iPhone 7 7s, 8 and X are already unlocked. So, if you’re using an iPhone 7 or a earlier model (iPhone 5, 6, 6s), it’s probably locked. Don’t worry; we’ll talk you through the steps so you can unlock your iPhone quickly and easily.

Is it legal to unlock my iPhone?

Despite what you might think, unlocking your iPhone is completely legal as long as you own the device. But, If you’re still paying for your iPhone through a contract, we advise you to check with your carrier before attempting to unlock it. More on this later.

Read below to find out whether your iPhone is locked, and how to unlock it.

How do I find out if my iPhone is locked?

If you purchased your iPhone 5, 6, or 6s direct from the Apple Store, it’s unlocked by default, which means swapping SIMs from any network is easy. Give it a try!

If you bought your iPhone 5, 6, or 6s as part of a contract, your phone is likely to be locked, and you will need to contact your service provider to unlock it (details on how to do this below).

To find out if your iPhone is locked, just follow these simple steps:

  1. Make sure you have two SIM cards to hand, one should be the one you own, the other from a different network
  2. Make a phone call using your current SIM card. Make sure it connects
  3. Turn off your iPhone
  4. Use the SIM-card ejector tool to remove the SIM card from the iPhone
  5. Insert your new SIM card
  6. Turn on your iPhone
  7. Make a phone call using the new SIM

If you fail to make a phone call with your new SIM, then the iPhone is locked. If your iPhone is locked, you’re likely to see an error message such as “Invalid SIM,” “SIM Card Not Accepted,” or “Insert Correct SIM Card.”

If you don’t have a SIM card from an alternate provider, you can check if your iPhone is locked in the settings menu. To do this, you will need a working iPhone.

  1. Open Settings
  2. Mobile Data > Mobile Data Options. (or ‘Mobile’ and ‘Cellular’ in older versions of iOS)
  3. Check for an option named Mobile Data Network (or Cellular Data Network)

If you see an option for Mobile Data Network, then your iPhone is most likely unlocked. This option will not be available for locked iPhones.

By now, you should know if you’re phone is locked or unlocked. If your iPhone is unlocked, then great. You can start to use your new SIM right away. If your iPhone is locked, we discuss how to unlock it, below.
