Vitelity dropping low volume A2P 10DLC

Not an Asterisk topic, but may be of general interest for discussion.

Vitelity is pulling the plug on A2P 10DLC (application-to-person 10-digit long code) SMS/MMS for low volume users.

If the 10 digit long code is a DID you rent from the vendor, why isn’t that enough to validate that you are who you are?

What are others doing?
