  I would do a specifications check on what frequencies that phone would work. I was on Cingular with an SE phone also back in 2005. I have a feeling that there isn't much luck it will work on T-Mobile.

    Here are the frequencies: GSM  850. 900, 1800, and 1900

     

    T-Mobile frequencies: 4G  LTE  Bands: 2. 4, 12, 66, 71

    Frequencies:  1900, 1700 def, 700a, 600

     

    Please don't ask me to explain as I don't have a clue.

  T-Mobile doesn't unlock devices they didn't sell.  You'd have to get Cingular (erm, now AT&T) to unlock it.  Or, some third party.

   

  That said, it's probably only a 2G device, and should work fine for talk/text.
