If your CRM is live but SMS features - like missed-call text-back or text reminders - aren't sending, the cause is almost always the same: your A2P registration hasn't cleared yet.
What A2P is: a one-time carrier approval required for all business texting in the US. Until it's approved, carriers block your texts. We submit it during onboarding, and approval typically takes one to five business days.
What to check: confirm your phone number is connected (Settings then Phone Numbers) and that registration status shows submitted or approved. If it's still pending, that's expected - everything non-SMS works in the meantime, and texting switches on automatically the moment it's approved.
Other quick checks: make sure the contact has a valid mobile number with country code, and that they haven't replied STOP (which opts them out of texts).
Still stuck after five business days? Contact [email protected] and we'll check the registration status and chase the carrier for you.
