I tend to agree with you. Examples: - My local garage sent me an SMS notification when my car's MOT was due. The notification included the number to call to book it in. - My bank sends me SMS notifications if my current account goes overdrawn, giving me time to log in to their app or online to transfer funds before I incur any charges. - A couple of the local taxi services send SMS notifications when my taxi is arriving (this isn't Uber - it's made it to Cambridge but they have very few vehicles so it's hopeless). These are all perfectly valid uses of SMS for one way communication/notification, or communication where the response isn't another SMS.
