But what happens when you have set up a SIM PIN a long time ago and then you forget it? And then, when you try to make a new one, you’ve managed to lock yourself out of your own SIM card due to several incorrect guesses at what your old SIM PIN was?

In such a case, if you wish to unlock your iPhone, there are two options available to you. First, either, your iPhone is tied to a certain mobile operator or carrier. The second is that you typed the wrong password or PIN code too many times, and your SIM card was disabled.

Here’s how to do it!

How to Unlock SIM Card for Use with a Different Carrier?

When you unlock your iPhone, that means you can use it with different carriers. Although all carriers have different processes, you’ll need a common list of information to unlock your phone. Before you begin unlocking your phone, make sure you have as many of the following items as possible.

  • Name and account number of the account holder
  • IMEI number of your device
  • Your phone number
  • The Social Security number or password of the account holder
  • A signed contract and/or a payment plan of the device
  • If you are in the army and want to unlock your phone before your contract expires, you will need to get overseas deployment documents.

Now that you have that details let’s look at how each carrier executes phone unlocking.

1. Unlocking an AT&T Phone

  2. Select Account on the upper left of the screen.
  3. Select the service plan to which your phone is subscribed.
  4. Click Check device unlock status under Device.

If the status reads “device unlocked,” your iPhone is already unlocked, and you’re good to go. If it says “device locked,” you must contact T-Mobile customer service by calling *6 from your iPhone.

When it comes to unlocking an iPhone on the Sprint network, all you have to do is dial 1-844-665-6327. You must provide the agent with your IMEI number.

Sprint frequently takes a few days to complete a phone’s unlocking, and service may be terminated after it’s fully unlocked. It’s important to have a SIM card from your new carrier ready to insert into your phone before unlocking with Sprint. If you want to keep your Sprint service, inform your customer care agent, so they don’t cut it.

4. Unlocking a Verizon Phone

Remember how we stated carriers require you to be a customer for a certain amount of time before unlocking your iPhone? Verizon does as well, except that this carrier unlocks your phone automatically.

According to Verizon’s device unlocking regulations, “devices purchased from Verizon are locked for 60 days after purchase.” After activation, devices purchased from one of our authorized retailers are locked for 60 days. We will automatically remove the lock after 60 days unless the gadget is judged stolen or purchased fraudulently. We do not lock our phones after the initial 60-day period.”

So, if you bought your phone from a Verizon authorized vendor, simply wait 60 days, and it will be unlocked automatically.
