Locked vs Unlocked Phones: Why It Affects Your Trade-In Value

If you've ever tried to sell your phone, you've probably been asked: "Is it locked or unlocked?" It's one of the most important factors that determines your phone's trade-in value—and the difference can be significant.

Let's break down what this means and why it matters so much.

What Does "Locked" Mean?

A carrier-locked phone is tied to a specific wireless carrier (like Verizon, AT&T, or T-Mobile). When you buy a phone through a carrier—especially on a payment plan or with a contract—it comes locked to that network.

Signs Your Phone is Locked:

• You purchased it through a carrier store or their website
• You're still making monthly payments on it
• You got it "free" or discounted with a new line of service
• You can't use a SIM card from a different carrier

What Does "Unlocked" Mean?

An unlocked phone can work with any compatible carrier. You can pop in any SIM card and it will connect to that network (assuming the phone supports their bands).

Ways to Get an Unlocked Phone:

• Buy directly from Apple, Samsung, or Google (factory unlocked)
• Request an unlock from your carrier after paying off the device
• Purchase a certified pre-owned unlocked device

How to Check If Your Phone is Locked

For iPhone:

1. Go to Settings > General > About
2. Scroll down to Carrier Lock
3. It will say "No SIM restrictions" if unlocked, or show your carrier name if locked

For Android:

• Insert a SIM from a different carrier
• If it works and shows signal, it's unlocked
• If it shows "Invalid SIM" or "SIM not supported," it's locked

Contact Your Carrier:

Call customer service and ask about your device's lock status. They can tell you definitively.

Why Unlocked Phones Are Worth More

Here's where it gets interesting for sellers. Unlocked phones consistently sell for 15-30% more than locked devices. Here's why:

1. Larger Buyer Pool

An unlocked phone can be used by anyone on any carrier. A T-Mobile locked phone? Only T-Mobile customers want it. This simple supply-and-demand reality drives prices.

2. International Usability

Unlocked phones can be used overseas with local SIM cards. This makes them popular for:

• Travelers
• International buyers
• Export markets

3. Resale Value

Resellers and refurbishers prefer unlocked devices because they're easier to sell to a wider audience.

4. No Carrier Restrictions

Buyers don't have to worry about compatibility issues or carrier-specific bloatware.
