Why this rule existsrationale

The sole proprietor tier is a low-volume path for individuals with no EIN, and the single-campaign, single-number limit is what the carriers accept in exchange for the reduced vetting. A second campaign is refused rather than queued, so somebody who registers a marketing campaign beside their appointment reminders loses the fee and the time. Pooling is the same limit stated the other way: there is only ever one number to pool.

How to fix itremediation

Fold everything the programme sends into the one sole-proprietor campaign, on one number, and turn number pooling off. If the business genuinely needs a second campaign or more throughput, obtain an EIN and re-register as a standard entity — the tier is the limit, not the campaign.

A compliant exampleexample

Sole proprietor: 1 campaign · 1 phone number · numberPool: false

Common mistakespitfalls

Registering the second campaign under a second sole-proprietor brand does not work either: the tier caps the mobile number behind the brands as well, so the same person cannot hold an unlimited number of them.
