Unlock an Iphone 5c T Mobile USA




    I'm from brazil, i bought an iPhone 5c some years ago in USA and unlocked it. Today, when a try to restore and update the device and IOS  system version, it don't recognize my SIM CARD then i went to internet to search for support, so I found a site that uses IMEI (a number sequence behind device) to check device status and for my surprise it's locked.


    Could you please help me to unlock this device again?


    IMEI: 01378700069XXXX

    Serial Number: F78L5DZEFFHG


    Any information that you need to solve this problem, I make myself available.


    OBS: I don't have a T Mobile SIM CARD anymore.
