Exactly this. I bet you'd have less than a 25% success rate of getting the average user to even know that SMS and "texting" are the same thing. Now try to get them to understand what "OTP" is.
Having to register a phone number with a service is bad enough. Forgetting what weirdo password you were forced to come up with--"a capital letter, a special character (but not % or *), and a smiley-face Unicode character"--is bad enough. But for those people who just get a new phone and phone number for whatever reason, now you have to get that changed as well.
The big problems with SMS is 1) it is insecure, and 2) it does not have any sort of guaranteed delivery mechanism. These are problems that are readily solvable with a combined technical/governmental solution. Develop a standard, say "all mobile companies must adhere to this in 12 months," and then use that. Even if it isn't perfect, i.e. somebody finds a small flaw in the implementation, it's better than it is now.
