- 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.
I'm really not. I see the impact 2-way texting is having on hundreds of retail stores everyday. It is a paradigm shift that seems obvious once you experience it.
