This Note is single sim but you can buy an adapter to make it dual sim. You need to download an app. to control this. I do not know how good or effective this system is.

If the inserting chip is the correct shape and size, then yes, you can. I use my Note I on a pay-as-you-go basis and had no trouble at all. Free SMS and messages is certainly a good saving on smart phones, and I use the same amount or less than my wife on an old brick Nokia!
