Do SMS cost money?
SMS fees are pure profit for the cellular carriers. They’re basically free for carriers to send, but they can often cost ten cents or more per message. It costs more to send a text message on Earth than it does to transmit data from Mars.
Is TeleSign free?
No Per User Fees or Ongoing Transactional Costs – TeleSign AuthID Kit is available free for TeleSign customers with consumer applications, removing a major cost barrier to providing advanced user authentication. Customers can configure how and when to use mobile application-based authentication versus SMS or Voice.
Can we create own SMS gateway?
Yes, but you need access to an SMSC on a GSM network to send the messages either directly or via a device with a SIM, thats what you pay for.
