Using Your iPhone Without Carrier Lock and No SIM Restrictions

September 3, 2023

Apple offers both locked and unlocked iPhones and iPads directly as well as via third-party vendors. If your device’s settings display no limitations, your iPhone or iPad is fully unlocked and ready to accept any SIM card. You can use your smartphone with many carriers as a result. When changing carriers, you only need to switch the SIM card. This is advantageous. Your unlocked iPhone or iPad, for instance, will be worth more if you decide to sell them. A used, locked smartphone won’t be appealing to customers.

Your iPhone or iPad is likely unlocked if you purchase it straight from Apple. Your device could be locked if you purchase your iPhone or iPad from a third-party vendor, such as a phone provider. This is particularly valid if you paid for it in installments. Your phone will probably continue to be locked to the carrier until the balance is paid in full. You may speak with your carrier about unlocking it once you’ve paid it off.

Navigate to Settings > General > About on your phone to examine it. The message will either read “No SIM restrictions” or “SIM locked.” Only the carrier can unlock your smartphone if it has been locked. If your device is paid off, your carrier will likely abide by your request.

How to check if your iPhone is locked or not

Some iPhones are “locked,” making them only functional on specific networks. How to determine if this is the case is as follows:

While some iPhones are tied to certain cellular networks, others may be used with any SIM card and service provider since they are unlocked. Knowing which kind you have is crucial since it may make a difference in whether getting a new iPhone or switching networks is a pleasant or difficult process.

The iPhones you buy at the full retail price (often from the Apple Store) are usually already unlocked. However, an iPhone purchased via a network will frequently be locked, typically as part of a contract. It should be obvious when purchasing a refurbished iPhone whether it is locked or not, but if you are buying from a private seller on eBay or Craigslist, this isn’t always the case.

It’s impossible to determine if an iPhone is locked or unlocked just by glancing at it. Apple prohibits other phone manufacturers from branding iPhones. (For instance, you can’t obtain iPhones with T-Mobile or Verizon branding.) The fact that some phones are locked when sold just adds to the confusion. Unlocked once the owner completes fulfilling the terms of the contract.

But do not worry. We’re going to explain how to determine whether your iPhone is locked or unlocked in this article.

Flexibility is the main advantage of an unlocked iPhone. With an unlocked iPhone, you are free to use any carrier and change carriers whenever you want without having to buy a new smartphone. In the long term, this might save you money because you won’t have to buy a new handset each time you switch carriers.

An additional advantage of owning an unlocked iPhone is the freedom from expensive roaming fees while using it abroad. Just buy a local SIM card in the nation you’re visiting and put it in your phone. You may use this to use your phone and data plan for a lot less money than you would if you were at home.

How to unlock your iPhone with R-SIM

How to unlock your iPhone with R-SIM

As long as you perform the procedures correctly, which are outlined below, using an R-SIM card is rather straightforward:

Step 1:

Take off your device’s standard SIM card, then place the R-SIM card on top of it. Don’t forget to put the SIM card tray back into your phone when you’re finished.

Step 2:

Start your smartphone and navigate to the home screen.

Step 3:

Either *5005*7672*0# or *5005*7672*003 should be entered when selecting the ‘Emergency Call’ option. Press the green dial button when finished.

Step 4:

Make your way to the ‘Edit ICCID’ option in the fourth step. Press “Send” after entering the code 89014104279605344456 or 89014104279605338458. Your iPhone will unlock if you do this.

After taking the above actions, bear in mind the following:

  • Don’t worry if you get an SMS saying “SIM not supported.” Restart your device instead, and you’ll see the problem go away.
  • If you receive a text message saying “No service,” return to your SIM apps’ main menu and select “Regain SIM signal.”
  • Make sure not to attempt a phone reset, as this would remove any previously saved settings.
  • Using two SIM cards at once is not recommended.
  • To prevent unwanted harm to your device, gently affix the R-SIM card beside your standard card.

To prevent any harm to your phone, carefully follow the directions above. We do, however, have a better choice if you are concerned that using an R-SIM card may harm your smartphone.

You have to set up your iPhone once more after a factory reset and reboot. Once it joins the Wi-Fi network, a pop-up will appear stating either “SIM card needed” or “There’s no SIM card installed.” It’s simpler to dismiss the pop-up if you’re using a new iPhone with iOS 14 or later, and the setup will still be successful without adding a SIM card.

To unlock an iPhone without a SIM card, follow these steps:

Step 1: To begin using an iPhone, tap the power button, swipe to the right to select Language > Country, and then select Setup Manually.

Step 2: Choose your Wi-Fi network and then input the password. When finished, click OK to dismiss the notification “No SIM Card Available” that appears on the screen.

Step 3: Tap Continue to accept the agreements for data and privacy on the phone’s screen. Next, choose Set Up Touch ID/Setup Later, and then go to Set Lock Screen Password.

Step 4: On the iPhone, go to Apps & Data, choose Setup as a New iPhone, and input your Apple ID and password. Click Continue after agreeing to the terms and conditions. To finish the setup process, follow the steps provided.

Your network provider may have shut down your iPhone. You may use your iPhone with many network carriers after unlocking it. These procedures can be used to unlock your iPhone by contacting your network operator. If your iPhone is locked, you may check by navigating to Settings > General > About.

Both locked and unlocked iPhones and iPads are available from Apple and independent retailers.

Your gadget could be locked if you purchase it from a third-party vendor, such as a phone carrier. Go to Settings > General > About to see if your iPhone is locked or unlocked.

After restarting and restoring your iPhone to factory settings, you may use it without a SIM card by setting it up once again.

Set up the Lock Screen Password and the Touch ID/Setup Later options.


Can I check if my iPhone is unlocked by IMEI? 

You may use your iPhone’s IMEI (International Mobile Equipment Identity) number to determine whether or not it has been unlocked. You may utilize online IMEI checking services or get in touch with your cell provider to do this. You can check your iPhone’s IMEI on a lot of websites and third-party apps to see if it has been unlocked or is still locked to a certain carrier.

Why is my iPhone unlock not working? 

Several factors might be at play if your iPhone cannot be unlocked:

  • Incorrect Unlock Process: When unlocking your iPhone, be careful to follow the correct steps outlined by your carrier or Apple.
  • Unpaid payments: Your carrier may be unable to unlock your iPhone if you have unpaid payments or contract commitments.
  • IMEI Not Clean: Your iPhone cannot be unlocked if its IMEI has been blacklisted as a result of being reported as lost or stolen.
  • Technical Problems: When unlocking a device, technical hiccups or difficulties might occasionally happen.

How do I format an unlocked iPhone? To format or reset an unlocked iPhone, follow these steps:

  • Data backup: Ensure that you back up your crucial information to iCloud or a PC using iTunes.
  • To perform a factory reset, select “Settings” > “General” > “Reset” and then “Erase All Content and Settings.”
  • Confirm: When asked, enter your passcode and Apple ID password.
  • Wait: The iPhone will reset to its factory settings and wipe all data.
  • Setup: To set up your iPhone as a new device or to restore from a backup, follow the on-screen instructions.

Can you get an iPhone unlocked and reset and still be able to use it? 

Yes, you can still use an iPhone after successfully unlocking and resetting it. You may use the smartphone with a SIM card from any supported carrier after unlocking it. The iPhone’s data and settings are merely deleted when it is reset; the phone’s functionality is unaffected. After the reset, you may either set it up as a new device or restore your data from a backup.
