SMS features "confirmation of message delivery". Unlike paging, users do not simply send a short message and trust / hope that it gets delivered. Instead the sender of the short message can receive a return message back notifying them whether the message has been delivered or not. Delivery is still not necessarily guaranteed. If message delivery is unsuccessful, the SMS service will retry only a finite number of times before giving up all together. SMS messages do not always arrive in a timely fashion. Frequently messages can arrive in a fragmented / disjointed manner or out of sequence with previous messages. This can be due to multiple factors, including but not limited to inter vendor network difficulties. Consider also that SMS is a way of sending a message with a device to a device not strictly speaking from one person to another. Possibly other individuals will see / manipulate the message before the intended recipient, depending on the security settings on the handset on the receiving side. For these reasons SMS is arguably an unreliable form of communication.
