You can send an sms internationally if your mobile service allows it but it will cost u extra. Local Sms here costs a max of 0.02 $ (converted from my currency to us dollars) to even a min of 0 $ (i.e free). Common charge is either .0067$ or .011 $ but i international sms costs you .11 $.
So the cost of max local sms is 5 times less than international.
Oh btw if yr wondering, i'm from india and the currency here is Rupees. (Just check out my profile.)
