How to Choose a Refurbished Phone

Refurbished is the Smart Choice

Buying a certified refurbished phone is one of the best consumer decisions you can make. You save up to 50% compared to new, contribute to the circular economy, and in most cases receive a device in excellent condition. But there are important things to check before buying.

Understand the Condition Grades

The grade is the classification of the device's visual and functional condition:

  • Grade A+ (Like New): No visible scratches, perfect operation. The best possible state for a refurbished device.
  • Grade A (Good Condition): Minimal signs of use, fully functional. Excellent value for money.
  • Grade B (Good): Visible scratches on screen or chassis, but fully functional. Good for those who want to save more.
  • Grade C (Fair): Significant wear. Suitable for basic use on a very tight budget.

At RM TechStore we mainly sell Grade A+ and Grade A — we guarantee that what you receive matches what you see in the photos.

Check the Warranty

A refurbished phone without warranty is an unnecessary risk. The minimum acceptable warranty is 3 months. At RM TechStore we offer 3 months to 1 year warranty, with technical support at our Lisbon store.

Confirm the Battery Has Been Tested

The battery is the component that degrades most with use. Ask about battery capacity — it should be above 80% for iOS (visible under Settings → Battery → Battery Health) or equivalent on Android. If the seller doesn't know or won't say, be cautious.

Check the IMEI

The IMEI is the phone's unique serial number. Before buying, request the IMEI and verify:

  • That the phone has not been reported stolen (use imei.info or local services).
  • That it is not carrier-locked.
  • That iOS Activation Lock is disabled (ask the seller to show the phone switched on and check under Settings → Apple ID).

Prefer Buying from a Physical Store

Buying online is convenient, but without seeing the device there is risk of surprises. In a physical store like RM TechStore you can:

  • Test the phone before buying
  • Check the visual condition in person
  • Ask questions directly to a technician
  • Get immediate support if something goes wrong
