What’s the difference: SMS vs. in-app messaging?
SMS messages are transmitted via cellular networks and appear in the general inbox of a mobile device. In contrast, in-app messages are transmitted over the internet and appear in the inbox of a specific app.
SMS (Short Message Service) and in-app messages are both forms of text-based communication, though they differ in a few crucial ways.
Delivery mechanism: SMS messages are transmitted via cellular networks and appear in a mobile device's general inbox. In-app messages are transmitted over the internet and appear within a specific app.
Accessibility: In-app messaging requires users to have installed the app and have internet connectivity to send, receive, and access messages. SMS can be received on any mobile device and requires no particular app or internet connection.
Cost: SMS are sent over telephony networks, and senders may incur costs from providers, such as Verizon or AT&T. In-app messages are sent over the internet and incur no charges outside of potential data usage.
Security: In-app messages can be encrypted, allowing more control over security features and user authentication. SMS are generally considered less secure because they’re a common medium for spoofing, phishing, and interception.
Use cases: In-app messaging is suited for instantaneous communication in an app, such as customer support, team collaboration, or social networking. SMS is often used for notifications, alerts, and one-time password (OTP) delivery.
In-app messaging and SMS are distinct communication channels that serve different purposes.
