Our detailed process from refurbishment to delivery.
Every step is optimized for minimal environmental impact.

Step 1. Grading

We grade each phone carefully.

When used or returned iPhone arrive at our factory, we carefully sort them into 4 quality grades depending on exterior condition:


As New: No visible scratches whatsoever.

Excellent Condition: Light scratches that are invisible from  20 cm away

Good Condition: Minor scratches and 1 or 2 deeper ones on the case or screen edge

Fair Condition:  Minor scratches and more than 2 deep scratches


If the phone is too damaged to be in fair condition, we pass it onto other providers and brokers.

Step 2. Factory Reset & Battery Change

Each phone undergoes a factory reset and is checked for the following:

  • Unlocked for worldwide use
  • Battery level is not below 88% or above 700 charging cycles
  • No iCloud Account associated with the phone
  • NOT blacklisted anywhere in the world

If the battery capacity is lower than 88% and/or the battery has been charged more than 700 times, our experts carefully remove and recycle the old battery and replace it with a brand new one certified by Apple.

*If the phone is blacklisted or locked, we pass it onto another provider. We do not sell locked or blacklisted phones.

Step 4. Cleaning & Free Gift

We disinfect the phone with environmentally friendly formula that removes any bacteria that might be present on your phone. Using specialist brushes, every crevice, speaker and mic hole, button, and charging port is thoroughly cleared of dust and particles. To protect your iPhone and make it last longer, we apply a glass screen protector free of charge.
