SMS vs Text: What’s the Difference?

The terms “SMS” and “text” are often used interchangeably to mean the same thing—a text message sent to a mobile device—but an SMS is actually a distinctly different channel of communication than what most consider a text message, such as Apple’s iMessage or an Android RCS message.

Look under the hood and you’ll see the difference. SMS (Simple Message Service) is a basic texting service with limited capabilities—simple text and a link or emoji—and relies on traditional cellular networks (GSM, CDMA, etc.), which allows messages to be sent when internet and wireless networks are not operational. In comparison, a text message sent through iMessage or What’sApp will allow additional functionalities such as enhanced security, animations, and reactions.

While SMS is a more basic service, its power lies in its simplicity. When your message needs to be seen, despite ground conditions, an SMS message is most likely to get through. SMS message pricing is also more affordable. MMS messaging, a slight enhancement to SMS, allows you to add one image or very short video clip to an SMS message.

RCS (Rich Messaging Service) was designed as a replacement for SMS, features enhanced functionality in line with Apple iMessage, and will be common to those on Android devices. But even with Apple’s adoption of RCS, which requires connectivity, SMS messaging, which can still be received without any data connectivity, will still have a place when delivery, speed, and cost savings are key.
