Want to switch your SIM for a better plan or use your iPhone data while traveling abroad? You’ll first need to unlock your iPhone from carrier most of the time. The good news is that you can unlock iPhone carrier online for free and there are also paid methods like Passixer iPhone Unlocker if you don’t qualify. Next, we’ll walk through both options step by step.
To check whether your iPhone is locked to a specific carrier, you can go to Settings > General and check the Carrier Lock item. If it’s written with SIM Locked, it means that your iPhone is carried-locked.
How Online iPhone Carrier Unlock Works
The online ways to unlock an iPhone carrier are by using your device’s IMEI. IMEI is a unique identifier of your iPhone. Online unlocking services will use that number to recognize your iPhone remotely and process the unlock on their end. Finding the IMEI is also simple and here are 2 common ways:
- Open Settings > General > About and then scroll until you see “IMEI”.
- Dial *#06# on the keypad and the IMEI will appear instantly on screen.


How to Unlock iPhone Carrier for Free Online
The only sure way to unlock your iPhone for free is by going through your network provider. Of course, carriers have their own rules for when they will approve a free unlock. You must meet these requirements before they will process the unlock.
In the US, the usual conditions include:
- All your bills must be cleared.
- Your iPhone must not be under an active contract.
- The minimum number of active days set by your carrier (40 days, 60 days, 6 months, varies by provider) should be completed.
In some countries, the rules are different. Like the U.K., for instance, carriers like EE allow you to unlock your iPhone for free whether or not the device is still under contract, as local regulations permit it.

Steps to Unlock iPhone Online Through Carrier
So, as long as you meet their rules, carriers will unlock the iPhone over the phone itself. Here’s the entire process:
What you’ll need: your IMEI (dial *#06#), the account details (if you’re a customer) and a reachable email.

How to Unlock iPhone Carrier with AT&T

How to Unlock iPhone Online [Paid]
The paid way to remove a carrier lock online is by choosing a third-party SIM unlock service. These sites ask for just two thing—your IMEI number and payment. Once they have it, they claim to process the unlock and let you use any SIM.
What method they actually use is rarely revealed. Still, a few site admins admit that they rely on backchannel methods, often by contacting carrier representatives directly. That’s how they say they can remove a lock even when your phone doesn’t meet carrier requirements or when you want the process expedited.
Here’s the caution. Almost every site in this space is risky. In fact, 98% of them are outright scams. They advertise high success rates, charge you upfront and then ask for more money to finish the unlock, but the unlock could never happens at all. Reddit is full of such stories.
