Yesterday we announced our new WordPress plugin for monetizing user registrations with Fortumo Premium SMS services. This plugin uses the same payment method (Fortumo), as our other plugin, SMS Read More (check it out).
How does this work?
When a visitor browses your WordPress register page, below standard registration field he will see new input field: SMS registration code. Below that, there are SMS sending instructions displayed. When the user sends an SMS message, he will soon get a reply message containing registration code.
