Our Exclusive Mail-in Service in Three Simple Steps

At Cosmo Repair, we offer easy phone repair mail-in services. Follow the instructions below, and we’ll be able to diagnose what’s wrong with your device and repair it in a fast manner. If you don’t have nearby access to one of our walk-in locations, our mail-in cell phone repair services, this is a great option to take advantage of.

This service includes the following:
  • A new quality replacement part installation
  • Exterior device cleaning
  • 36-point inspection and report

Before starting your repair, we’ll run our device inspection. This includes running tests on 36 essential components. Everything from brightness control to dock connection. If we assess anything that needs urgent attention, we may contact you before starting your device repair. As part of our quality control, we run the same in-depth inspection on your device after completing the repair service. After finishing, we’ll provide you with a printed copy of the report in your return shipment.
