Switching carriers or using a different SIM card on your iPhone doesn’t have to be complicated. If your device is SIM-locked, it can prevent you from connecting to other networks, causing unnecessary frustration. In this guide, we’ll show you how to unlock your iPhone SIM card quickly and safely, so you can use it with any carrier without hassle. Whether your iPhone is new or pre-owned, these proven methods make getting full control of your device fast and easy.
To see whether your iPhone is SIM-locked, follow these steps:
Open Settings: Tap the Settings app on your iPhone.
Go to General: Scroll down and select General.
Tap About: In the General menu, tap About.
Check Carrier Lock Status: Look for Carrier Lock. If it says No SIM restrictions, your iPhone is not SIM-locked. If it displays SIM locked or mentions a specific carrier, your device is SIM-locked.
How to Unlock Your SIM Card for a Different Carrier
While there are several ways to unlock a SIM card, Passixer iPhone Unlocker offers the simplest and most efficient solution. With Passixer, you can remove the SIM lock from your iPhone without contacting your carrier or risking any data loss. Whether your iPhone is brand new or pre-owned, unlocking it with Passixer allows you to use SIM cards from any mainstream carrier. Here’s a step-by-step guide on how to unlock your iPhone carrier using Passixer.
Step 1: Open Passixer & Connect Your iPhone

Step 2: Jailbreak Your iPhone (If Needed)

Step 3: Verify Device Information
Passixer will detect your iPhone and display its details. Check that all information is correct before proceeding.
Step 4: Prepare for Unlock
Disconnect all Wi-Fi networks and turn off Wi-Fi on your iPhone to ensure the SIM unlock process goes smoothly.
Step 5: Remove the SIM Lock
Start the SIM lock removal process. Once it’s complete, your iPhone will be fully unlocked and ready to use with any compatible carrier.
If your iPhone is locked to the AT&T network, you can request an official unlock to use it with any other carrier. AT&T provides a dedicated page where you can submit your unlock request by entering your IMEI number (dial *#06# on your phone to find it) and your mobile number. Once AT&T approves your request, your device will be ready to switch to any compatible network. You can also use the same page to check the status of your request. Additionally, AT&T offers the AT&T Device Unlock app, which lets you submit an unlock request directly from your iPhone.
Open a web browser like Mozilla Firefox or Safari and log in to your MyT-Mobile account (note: this must be done on the website, not the app). Click Account in the top-left corner, then select the service plan linked to your iPhone. Under Device, click Check Device Unlock Status. If it shows “Device Unlocked,” your iPhone is ready to use with any carrier. If it says “Device Locked,” you’ll need to contact T-Mobile customer service by dialing *6 from your iPhone.
Sprint can unlock the SIM card slot for eligible devices, as outlined in their Unlock Policy on here. If your device qualifies, Sprint will either unlock it remotely or provide instructions to complete the unlock if remote unlocking isn’t possible.
To request a SIM unlock for your eligible postpaid device, contact Sprint Customer Care by dialing *2 from your Sprint phone or calling 888-211-4727.
If your iPhone shows a “SIM locked” message, it can be frustrating—especially if you accidentally pressed Cancel and didn’t get a chance to enter your PIN. Luckily, there are ways to bring up the unlock screen again and regain access to your SIM.
Before you begin, check whether your SIM card uses a default PIN. If you haven’t changed it, you can usually find it in the SIM card’s packaging or manual. Some carriers also provide a Super PIN to help unlock the SIM if multiple incorrect PIN attempts have been made.
The easiest approach is through your iPhone’s Settings. Go to Cellular > SIM PIN, where you can enter your PIN to unlock the SIM or change it to a new one. This method quickly brings up the unlock prompt and manages your SIM PIN settings directly.
You can also unlock your SIM via the Phone app. Simply initiate a call to any number or contact, and the SIM unlock prompt will appear. If you don’t want to make a real call, entering a random number like “333” and pressing the green call button works just as well. Once the prompt appears, input your SIM PIN to unlock the card.
Quick Tip: If you hit Cancel by mistake, just repeat the steps above to bring the unlock screen back.
This approach allows you to unlock your iPhone SIM without contacting your carrier while keeping control over your SIM PIN settings.
Unlocking your iPhone SIM card for use with any carrier doesn’t have to be complicated. With Passixer iPhone Unlocker, you can quickly and safely remove the SIM lock without contacting your carrier or risking data loss, making it the fastest and most convenient option. Alternatively, each carrier—AT&T, T-Mobile, and Sprint—offers official methods to unlock your device, though these may require account verification and waiting periods. For users who prefer not to involve the carrier, iPhone’s built-in Settings and Phone apps also provide ways to unlock your SIM directly. By following these methods, you can regain full flexibility to switch networks and use any compatible SIM card on your iPhone.
