What is an online SMS gateway?
An online SMS gateway is web-based software that businesses use to send text messages. Most SMS gateways will have a Dashboard, where you can add contacts and send text messages straight from your browser. Or you can access the gateway via SMS APIs to build messaging capability into other apps.
SMS gateways allow computers to talk to the cell networks, by converting SMS into the format used by the networks. As businesses grow and scale, it becomes impossible to contact customers from a cell phone (what we call person-to-person messaging). That's why business texting is done through SMS gateways, a type of 'application to person' software.
And billions of text alerts, appointment reminders and marketing SMS are sent through the web every single day.
