I saw this on reddit and wanted to share it <3
Cell phone plans cost roughly 20$ and include 1000+ SMS (on average). According to SMSChain this means you would earn 150$ per month. Per 100 SMS you get 15$, making a single text message worth 0.15$. Now why would any company want to pay 15 cents per SMS? There are professional services, such as Twilio, whose messages cost around 0.0075$. Do you see the difference? For roughly 1 cent you get a professional service, whereas for 15 cents you get your SMS delivered in a unprofessional manner.
