Why aren't my text-backs or summary texts being sent?

Most often it's texting approval. Carriers block texts from business numbers until they approve the business, so open Phone, then Texting approval: “Waiting on carriers” or “Brand approved, campaign in review” means it's on its way; “Not approved yet” means fix the details and resubmit, or switch to toll-free verification.

Once approved, a text-back still won't go when the caller's number was hidden, they already got one in the last 24 hours, they replied STOP, or it's outside 8 AM to 8 PM their time (it waits for the morning). It can also be switched off in the Texts tab.

Summary texts to you need your cell verified in Settings, Notifications and “Text me the summary” on; texts that arrive during your quiet hours wait until they end. The email summary always arrives if it's switched on.
