    Hi all,

    I ordered an international version of BB Z10 (STL-100-1). I live in USA. When i tried to use the phone with GSM carrier (AT&T and T-Mobile), it didnt worked.

    Does GSM carriers in USA support atleast talk and text in STL-100-1 ?

    I'm almost certain I used a STL 100-1 during May 2013 in Florida on TMO when attending BlackBerry Live 2013.

    I have all devices so I might remember wrong...

    It still works. The only thing you won't get is 4G LTE

    It should have worked on both AT&T and TMO. Are you sure it was an unlocked phone?
