First, a utility number that I send myself programmatic alerts[1] and do general messaging management with has broken entirely and it is certainly the result of A2P 10DLC and my "failure" to create a business entity for sending reminders to myself.

Second, the messaging - both email alerts and direct from customer support - has been crystal clear:

ALL SMS is a campaign. It is all spam. You need to register and qualify and opt-out your spam or you can't send your spam.

So yes, actual problems.

[1] Again, Jeff, what kind of (required) opt-out message should I craft for myself ? What if the third party ad-industry working group doesn't approve of my unsubscribe methods that I give to myself ?

Presumably their model would handle this based on your usage patterns, without needing to craft a specific “opt out” message.
