Q: About the non-premium number, can I use the the international number to bill adult content? If yes, how much I can bill (min-max)?
A: The nature of non-premium numbers does not allow you to bill. Hence the NON-premium, as opposed to PREMIUM messages where you do bill the user.
Perhaps you are looking for our SMS LONG CODE, where you can bill a small amount. You can find details of this via http://txtnation05.txtnation.com/payout.php?type=sms&option=lc
