title: SMS payment solution
body: <p>I want to integrate a SMS payment solution for my website. I will be offering some premium content and as the prices are not high (1, 3, 5 or 10 Euros) and I would want to use a SMS payment solution.</p>
  
  <p>Unfortunately, I didn't find any providers.</p>
  
  <p>I want the service to provide an API so that the user never has to leave my website.</p>
