How does an SMS Gateway work?

Simply explained, SMS Gateway (Also called SMS API) is software that connects your system or application with the mobile network. It allows you to send and receive SMS directly integrated into your own software, for example to send out automatic SMS alerts or one-time passwords.

By using our SMS API, you can take advantage of the power of SMS communication. Our system is flexible and user-friendly, making it easy to get started.

"In our staffing and schedule planning system, Flex HRM Plan, the supervisor or a manager can send out a work shift request via SMS to the employees, who respond with an SMS whether they can take the passport or not. If the answer is yes, the work shift is automatically added to the system. It works great!"
