## Why this rule exists

Investment solicitation over SMS is heavily associated with pump-and-dump and fraud, so carriers refuse the category rather than assess individual senders. A regulated institution servicing existing accounts is judged separately.

## How to fix it

Investment solicitation cannot be registered. Account servicing for existing customers of a regulated institution is a separate category — frame the campaign that way if it applies.
