What is SMS
SMS stands for Short Message Service. It is the core text messaging protocol used by carriers and supported on nearly every mobile phone, which is why it remains the fallback for many alerts and one-time codes.
Why SMS is still used
SMS is widely supported, simple, and reliable for short text. It is often used where broad compatibility matters more than rich media features.
SMS limits to know
SMS is text-first and may split long messages into multiple segments. It does not provide advanced chat features in the way RCS or app-based messaging systems do.
