Tex - What inspired this comment was remembering having seen ads around Recoleta for small companies - usually catering to businesses, I believe - advertising fiber optic internet service etc ... now, I have no idea about any of this but I remember thinking 'If I get fed up with the big companies, I know what to do'. Now I am wondering how to find them, even just to make enquiries, but sadly I didn't make any notes of company names/ contact numbers etc and it's been a while.
I suspect you saw billboards for SION -- the only reference I have for them unfortunately is a friend complaining about her service going down via her facebook feed... I can't comment more about them but you could google around and see if there's more recommends out there for them: http://www.sion.com/home.htm
