How do you get around the fact they don't receive commercial short numbers? I need to get verification codes from my bank and so on for that to work.

You can email them to enable receiving short codes for a specific number. That doesn't mean it works with all banks or whatever (the sending company may not allow Twilio numbers), but it does work for some of them.

I did that and it didn't help. Thankfully most companies support "Voice call verification" which does work.

Have you ever had a company refuse to voice call verify a twilio number?

The issue with SMS, in my limited understanding, is commercial numbers tend to come through shortcodes and shortcodes have their own set of delivery rules. Nothing of the sort from voice calls. I haven't had any instances of voice calls not coming through.

My (minimal) understanding of telecoms is the future is always a very long way away if you relying on complete rollout for usability.

Skimming that page, it also looks like possibly this is only replacing commercial long code users, not commercial short code users? But I didn't read carefully enough to be sure.

I had to give up getting short codes (or so I thought until I read the comments here).
