I`m from Norway and we been working with SMS advertisement for an while and it been working okay but here the users feel it to intrusive. So I been looking for different advertisement product and for some month ago I did find an unique product how`s NOT disturbing or intrusive for the user and it look nice. It`s on the idle screen. It? work like every time when you are "using" your phone the banner changing on the idle screen.
Do you have any similar in your country?
