What's an SMS gateway?

What’s an SMS gateway?

Glad you asked! An SMS gateway like Sinch MessageMedia allows you to send text messages from a computer to a phone over the global telecommunications network. You can think of it like a translator service. It takes your message from your computer and makes it compatible for the network, so it then gets delivered as SMS to someone’s mobile phone. The SMS Gateway translates the message sent, and makes it compatible for delivery over the network to be able to reach the recipient.
