How to Buy a Used Smartphone

On February 25, 2026 By newsroom Topic: Technology Buyers Guide

Buying a used or refurbished smartphone can save money and help the environment. However, it comes with some risks. Here's what you need to know to make a smart purchase.

1. Key Considerations Before Buying a Used Smartphone

Check Network Compatibility

CDMA vs. GSM:
Sprint and Verizon use CDMA networks.
AT&T and T-Mobile use GSM networks.
Best Option: Choose a phone compatible with all carriers (e.g., Google Pixel, Verizon/Sprint iPhone 7 and 7 Plus).
Use tools like willmyphonework to check compatibility and network access.

Ensure It Wasn't Reported Stolen

Activation Locks: Ensure theft-deterrent features (e.g., iPhone’s Activation Lock, Android Device Manager) are deactivated.
Check IMEI:
Find the phone’s IMEI number under Settings or by dialing *#06#.
Verify the phone isn’t reported stolen using tools like imeipro.

Carrier Lock Issues

Phones might still be locked to the original carrier. Bring the device to your new carrier to confirm compatibility.

Check for Water Damage

Look for the moisture indicator:
Removable Battery Phones: Behind the battery or near the SIM card slot.
Non-removable Battery Phones (e.g., iPhones): Inside the SIM tray.
Use a flashlight or magnifying glass; a red indicator means water exposure.

2. Should You Buy a Refurbished Phone?

Refurbished phones are inspected and restored for quality, often including new batteries and warranties.

Benefits of Refurbished Phones

Cost Savings: Often hundreds less than new models.
Environmental Impact: Buying refurbished reduces COemissions and raw material use.
Certified Refurbishment: Manufacturers often restore phones to "like-new" condition.

Things to Look For in a Refurbished Phone

Certification:
Apple and Samsung offer rigorous inspections, including battery replacement.
Look for certified sellers like Amazon Renewed or Best Buy.
Warranty:
Apple and Samsung offer 1-year warranties; others, like Best Buy and Walmart, may only provide 90 days.
Accessories: Ensure the phone includes original or high-quality replacements, especially for chargers.

Return Policy

Look for a return window of at least 30 days.
Amazon Renewed offers 90 days, while Apple and Best Buy provide only 14 days.

3. Tips for Buying Safely

Buying Online

Stick to reputable sellers like Apple, Samsung, Best Buy, and Amazon Renewed.
Avoid deals that seem too good to be true—cheap phones may have defects or missing features.

Buying in Person

Inspect the phone carefully for cosmetic flaws.
Test key functions like the touchscreen, camera, speakers, and battery life.
Verify the IMEI and check the moisture indicator on the spot.

Testing the Device

Look for fast performance, no lag, and responsiveness.
Test connectivity: make a call, send texts, and connect to Wi-Fi.
