How to Buy a Used Smartphone

On February 16, 2025 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.
