We have achieved a breakthrough. After modifying the system, the QIN F21 pro mobile phone can use the T-Mobile network in New York and other areas in the United States. No need to rack your brains to modify its system yourself, let us do the professional work. Note: This mobile phone system band is an unofficial version, and the mobile phone you purchased from AliExpress or Amazon is not an official version. There is currently no US-specific version of the official website. However, for mobile phones purchased from our website, we will make a commitment and warranty for the system security. We guarantee the quality of the products currently sold on our website
