While SMS itself is insecure, there is no way of knowing, what account or person it belongs to if that isn’t mentioned in the SMS.
Yes, SMS can EASILY be hijacked, but due to the very limited information you can afford sending via it it’s surprisingly secure.
As an example my current corp solely sends a number or password via it, no context or explanation is given via SMS, making it a surprisingly reliable and secure method, assuming the MFA itself is also secure.
Honestly, probably not much less secure than SMS.
