Many years ago I bought a 3G phone that was dual sim, the frequencies were for Asia or Europe, not North America. Phones and frequencies and standards are different now, but if you shop for a dual sim phone, I suggest you make sure the frequencies that the phone is wired for are the frequencies used by your provider.
