They can't, it makes no sense to add such encryption to SMS. The end user would have to manually manage keys. It didn't make sense on WhatsApp or iMessage either of course but for different reasons - there the problem is the apps are a monopoly for that service. They can update at any time and alter the encryption as they see fit. They already did this to stop people forwarding messages on WhatsApp, which makes a mockery of the concept of e2e encryption.
