If you're an iPhone 7 owner, you may have found yourself facing one frustrating issue: your iPhone is locked to a specific carrier. This is especially common when you purchase a phone through a carrier, and they tie it to their network. But don’t worry! Unlocking your iPhone 7's SIM is easier than you think. In this article, we will show you the step-by-step process of how to SIM unlock your iPhone 7 and 7 Plus, including tips on how to unlock it for free and even how to bypass certain restrictions. Ready to free your iPhone? Let’s get started.

So, what exactly is a SIM lock? Think of it as a leash tied by your original cell phone provider (the carrier) to your iPhone 7. This leash prevents you from using any other company’s SIM card in your phone. If you want to:
• Switch carriers: Maybe another company has a better data plan, or you're finally moving to that unlimited everything package. If your phone is locked, you can't just move your number.
• Travel internationally: This is the big one! Trust me, grabbing a local SIM card while traveling is your wallet's best friend, and it beats paying those astronomical international roaming fees any day. A locked phone makes that impossible.
• Sell your iPhone for more: An unlocked iPhone 7, especially one that can boast the title of being a genuinely open device, is worth significantly more than a locked one. People pay a premium for freedom!
Knowing how to SIM unlock iPhone 7 means holding the reins of your own mobile destiny. Let’s get to the good stuff.
There are two primary ways to liberate your iPhone 7. The first is always the best, and the second is an option for tricky situations.
This is the golden ticket. Your carrier is the only entity that can officially and permanently remove the SIM lock from your iPhone 7, and thanks to modern regulations and policies, they usually have to do it for free if you meet their requirements.
This is exactly how to SIM unlock iPhone 7 and 7 plus free or the standard model:
Before you call, gather your phone’s information and check if you meet the requirements. These usually include:
• Contract completion: Is your payment plan or contract completely fulfilled? If you bought the phone on installment, it needs to be fully paid off.
• Estado de la cuenta: Is your account in good standing? No past-due bills or other administrative hangups.
• Time on network: Some carriers require the phone to have been active on their network for a certain number of days (e.g., 40-60 days).
• IMEI number: You need your phone’s unique ID. To get it, just dial * # # 06 on your iPhone 7. Write this 15-digit number down!

Even if you think you’ve paid it all off, always double-check. It’s better to confirm it now than get denied later. Also, having the IMEI ready when you call makes you sound like a pro!
Call or use the online chat service for your carrier.
Tell them clearly, I need to request a SIM unlock for my iPhone 7 (or 7 Plus) because I’ve fulfilled my contract.
• They will verify your eligibility using your account info and the IMEI number.
• The carrier will then submit a request to Apple. This process is not instant. It usually takes 2 to 10 business days for Apple to process the unlock.
You won't get a code like older phones. Once the carrier confirms the unlock is processed, you need to do one of two things:
1. If you have the original SIM: Insert a SIM card from a different carrier. Your phone will connect to Wi-Fi and automatically complete the unlock process. You'll see a message that says, SIM not supported, followed by a message confirming the unlock.
2. If you don't have a new SIM yet: Back up your iPhone 7, erase it, and restore it from the backup. This forces the device to check with Apple’s servers and apply the unlock. This is a common way to figure out how to unlock an iPhone 7 or 7 Plus without a SIM card (if you don't have the new one handy, that is). In this way, you can know if your phone is unlocked without a SIM card.

And just like that, you've figured out how to unlock a SIM network pin for your mobile phone.
Sometimes, the carrier says no (e.g., if you bought the phone from a friend who still owes money on the plan), or you just don’t want to deal with the waiting time. This is where third-party online unlocking services come in.
Although a fee is involved, these services can quickly process a carrier unlock because they have direct access to specialized databases and wholesalers.
Be extremely cautious here. Only use reputable services that offer money-back guarantees. A simple Google search for iPhone unlocking service reviews is mandatory before spending any money. You’re typically paying for a faster process, but you need to provide your IMEI, so make sure the site is secure!

Now that your iPhone 7 is carrier-unlocked, there’s another type of lock you might encounter: the SIM PIN. This is a security feature you control that prevents unauthorized people from using your SIM card to make calls or access data if your phone is stolen.
If you keep seeing a prompt for a SIM Lock or SIM PIN when you turn on your phone, this is what you’re dealing with. It’s different from the carrier lock!
Here is how to unlock iPhone 7 SIM lock settings:

If you input the wrong SIM PIN three times, your SIM card will lock instantly, requiring a PUK (Personal Unblocking Key) code to bring it back to life. If you’re ever in this pickle, contact your current service provider immediately for the PUK code. Do not guess it! Guessing the PUK code wrong multiple times can permanently disable your SIM card, and then you’ll need a new one. This is key if you’re trying to know how to unlock a SIM card without PUK code for iPhone 7, and the answer is you can't guess it. You need the PUK from the carrier!/p>
Let's say you've conquered the SIM lock, but now you’ve forgotten your screen passcode or you bought a phone that's locked with an old Apple ID. This is a separate, device-level lock.
If you’re wondering how to unlock an iPhone 7 without a SIM card and passcode because you’re completely locked out of the operating system, you might need a dedicated tool, Desbloqueo iPhone Aiseesoft. This tool is designed for more serious unlocking issues that go beyond the SIM card:
