About Us
Your Reliable Partner for Wholesale Used and Refurbished Mobile Phones
About INENG TECHNOLOGY
INENG TECHNOLOGY CO., LIMITED is a China-based supplier specializing in wholesale used phones and refurbished phones wholesale for global B2B buyers. We have sourcing and operational support in China, as well as an office in Hong Kong to support international business communication and trade operations.
We supply tested mobile devices in bulk to wholesalers, distributors, importers, resellers, repair shops, and online sellers worldwide. Our main products include used iPhones wholesale, refurbished iPhones, used Samsung phones, Android phones, unlocked phones, and mixed stock lots.
In the used and refurbished phone business, buyers care most about product condition, stable supply, clear grading, and reliable quality control. That is why we focus on transparent Grade A/B/C classification, functional testing, battery health options, careful packing, and fast quotation support.
How We Test Our Phones
Before shipment, our team carries out a practical quality control process to make sure each batch meets the agreed condition and functional requirements. We check the key functions that matter most to wholesale buyers, including:
- Power on and power off
- Screen display and touch response
- Front and rear cameras
- Speaker and microphone
- Charging port and charging function
- Wi-Fi, Bluetooth, and network connection where applicable
- Face ID or Touch ID where applicable
- Battery health and battery performance
- Buttons, vibration, and basic sensors
- Cosmetic condition and Grade A/B/C classification
- IMEI or carrier status check where applicable
For wholesale orders, we can also provide photos, videos, grading details, and available stock information before shipment. Our goal is to help buyers clearly understand what they are purchasing and reduce sourcing risk before placing repeat orders.
How We Work with Customers
We believe long-term business is built on honesty, clear communication, and stable product quality. Instead of only focusing on one-time sales, INENG TECHNOLOGY aims to build reliable relationships with overseas buyers who need a consistent supply of used and refurbished mobile phones.
We understand that every market is different. Some buyers need Grade A devices for retail resale, while others need more affordable Grade B or mixed stock for price-sensitive markets. Our team helps customers choose suitable models, grades, battery options, and order quantities based on their target market and sales channel.
We value every customer relationship by providing fast responses, realistic stock information, clear product descriptions, and practical after-sales communication. Whether you are buying wholesale used phones, sourcing refurbished phones wholesale, or looking for used iPhones wholesale for your local market, we aim to support your business with dependable supply and professional service.
With sourcing and operational support in China and an office in Hong Kong, INENG TECHNOLOGY is positioned to serve global wholesale buyers with available stock lists, flexible order quantities, export packing, and international shipping assistance.
Our goal is simple: to be a reliable long-term supplier of used and refurbished mobile phones from China.
