Shirish, 31 Oct 2013I hv Duo but internet works only on CDMA but not on GSM network . the menu itself does not app... moreone of the worst model ever samsung had produced without an option of gsm internet activation profile. Waste of money & time. Do not buy this model even in second hand.
Will it work on t-mobile network in USA. I am travelling to usa and have this handset. If I buy a local connection in USA, will the SIM work?
