Never heard of them LOL

That being said, from what i am told sales made via SMS or Mobile billing are very limited and unless you have a custom solution to process those transactions and credit affiliates with their sales you will probably lose affiliates because of offering it as a payment option on your sites.

SMS billing is still in its infancy in the United States whereas for the rest of the world it has been a growing business model for years (We had it in the UK at least 10 years ago).
