The cost of google voice is free. If you go post something on craigslist and show your phone number as a contact method, I guarantee you that you will soon get spammed by google 2FA notifications. Around me they seem to be primarily set to a Vietnamese language. I live in the same city as the AT&T headquarters. AT&T and Google could also have systems to help prevent these scams, for instance I could specify the languages I speak and if SMS messages arrive in a different language, they could allow me an SMS command to flag a sender as the trigger-er of the phishing attempt. However, AT&T could also make a phone app for billing that loads menus in less than 30 seconds to a minute, and considering they've done neither I suppose I'll take the billing app first since it gets more use than craigslist does. After all, we only pay them 60 dollars a month for a phone and another 60-100 dollars a month for DSL for quite literally decades, so I wouldn't want to strain them by requesting too much in the way of a basic level of service.
