How to Unlock a Carrier-Locked iPhone (And Where to Sell Locked or Unlocked iPhones)
If you’re wondering how to unlock a carrier-locked iPhone, you’re not alone. Millions of people search every month for ways to unlock iPhones from AT&T, Verizon, T-Mobile, Sprint, and other carriers. Whether your goal is to switch carriers, increase resale value, or simply understand your options, this guide explains everything you need to know about unlocking an iPhone.
The good news? Even if your iPhone is locked and cannot be unlocked, you can still sell it for cash. FlipaCell buys both locked and unlocked iPhones, making it easy to turn your device into money without hassle.
What Does It Mean When an iPhone Is Carrier Locked?
A carrier-locked iPhone is restricted to work only on one specific network. For example, an iPhone locked to AT&T will not accept a T-Mobile or Verizon SIM card. Carriers usually lock iPhones when:
The phone is purchased through monthly payments
The device is part of a carrier promotion
The account balance is not fully paid
Unlocked iPhones, on the other hand, can be used on any compatible carrier worldwide.
How to Check If Your iPhone Is Locked or Unlocked
Before attempting to unlock your iPhone, you should confirm its lock status.
Method 1: Check in Settings
Go to Settings > General > About
Scroll to Carrier Lock
If it says No SIM restrictions, your iPhone is unlocked
Method 2: Try Another SIM Card Insert a SIM card from a different carrier. If it works, your iPhone is unlocked. If not, it’s locked.
How to Unlock an iPhone From Major Carriers
Unlock iPhone From AT&T
To unlock an AT&T iPhone:
The device must be fully paid off
The account must be in good standing
The iPhone cannot be reported lost or stolen
You can submit an unlock request directly through AT&T’s official unlock portal. Approval usually takes a few days.
Unlock iPhone From Verizon
Most Verizon iPhones are automatically unlocked after 60 days from purchase. If your iPhone is still locked, contact Verizon customer support to verify eligibility.
Unlock iPhone From T-Mobile
T-Mobile requirements include:
Device must be paid off
At least 40 days of active service
Account in good standing
Once approved, T-Mobile sends unlock instructions via email or pushes the unlock remotely.
Unlock iPhone From Sprint
Sprint (now part of T-Mobile) follows similar rules:
iPhone must be paid off
Account must be active and in good standing
Device must not be blacklisted
Can You Unlock an iPhone That Is Not Paid Off?

Outstanding balances
Unpaid installment plans
