We adhere to a rigorous inspection, testing and strict grading process so you always know exactly what to expect with your purchases from B2B Mobile. Take a look at the comprehensive, yet easy to follow Cosmetic and Functional Grading scales below. Our B2B team is available if you ever have any questions.
We also sell a variety of phones that are perfect for qualified repair shops.
Phones that are functional but can have a variety of non-critical issues. Such as:
- Face ID
- Biometrics Fail
- Non OEM Parts Message
- LCD with black dots/spots/halos
- Cracked Glass

Those devices are sold as Mixed Grade only and are combined in a separate list for sale.
