This wikiHow teaches you how to determine if your iPhone is network-locked. The easiest way is to call your carrier and ask, but there are a few other ways that will help you guess the locked status of your iPhone. Unfortunately, there is no free online service that you can use to check the unlock status of your iPhone.
Steps
General methods
- Verizon – 1 (800) 922-0204
- AT&T – 1 (800) 331-0500
- Sprint – 1 (888) 211-4727
- T-Mobile – 1 (877) 453-1304
- Normally, you’ll need to provide your account password (if you have one) and your iPhone’s IMEI number (located in Settings > General > About > IMEI ).
- iPhones purchased from a third-party seller, such as Amazon or Craigslist, will usually come with some form of documentation titled or invoiced as “Unlocked” if the iPhone is unlocked.
- If you bought a used iPhone from a friend or online classifieds, ask the seller if the iPhone is unlocked (preferably before the transaction).
- The main exception to this is active duty officers in the US, who can request a network unlock prior to departure regardless of the iPhone’s billing status.
Check iPhone settings
Settings of iPhone. Click the Settings app icon in the shape of a gear set in a gray frame.
- If your phone language is not US English, you need to tap Cellular Data or Mobile Data here. [1] X Research Source
- On some phones, like AT&T, you’ll need to tap Cellular Data Options first to see “Cellular Data Network”.
- In extremely rare cases, your carrier will provide you with a SIM card that allows you to change your iPhone’s access point name or Access Point Name (APN), but the phone remains unlocked. If your phone has such a SIM card, proceed to the next method.
With another carrier’s SIM card
turn right.
- The power button is located on the right side (iPhones 6 and later) or on the top edge of the phone frame (iPhones 5S and earlier).
- On iPhone X, you have to hold down the power button and either volume button until the switch appears.
- The iPhone 3G, 3GS, and early iPhones had a SIM slot located on the top edge of the phone’s chassis.
- You need to make sure that the SIM tray is in place before continuing.
- If your iPhone has a passcode, you’ll need to enter the passcode or use the Touch ID sensor to open the Home screen.
- If a message asking for “Activation Code”, “SIM Unlock Code” or similar error appears when you open the Phone app, the phone is network locked.
Advice
- There are many online services that allow you to check your iPhone’s IMEI number in the list of unlocked iPhones (for a fee). Unfortunately, the results of these services are not guaranteed to be successful, so you need to be careful when using them. In general, calling your mobile carrier is the best way to find out if your phone is unlocked.
Warning
- Busy should be careful when handling the SIM card.
- The only websites that can provide accurate information about iPhone unlock status through IMEI number will charge a service fee. These sites need access to Apple’s GSX database, which is not accessible to everyone, and is expensive to do so.
- If you come across a free website that provides IMEI unlocking information for iPhones, chances are that the content on the page is outdated and therefore no longer accurate. [4] X Research Sources
