1. Business philosophy: "Cherish every penny of customers and provide customers with products that are worth the money", this is our business philosophy! For this reason, we have been working hard and covering major markets around the world.   

2.About the phone:  We eliminated 90% of the used phones, selected a very small number of beautiful phones, and repaired some minor flaws! If you put this phone together with a new phone, you can't tell the difference. Its performance reaches 99% of the new phone, but the price is much cheaper. We also optimized the system for this phone to better adapt to the local telecommunications network, and gave away a charging head and data that are completely in line with the local. Yes, it is a great phone, whether it is given to others or used by yourself. In addition, we provide a two-month warranty service for the motherboard and battery of this phone, although referring to our historical data, the phones we sell rarely have problems.  

3.Warm reminder: Our warranty Service does not include the mobile phone operating system. The maintenance  of the system are very professional matters. Please do not install apps or plug-ins other than the Play Store, do not restore the system to factory settings, and do not reinstall or modify the system!
