How fast can I start sending?

Most teams send their first messages the same week they onboard. iMessage has no A2P registration, so there is no brand vetting, no campaign approval queue, and no waiting on carrier review before your first send. Your line is ready after white-glove activation, and your onboarding call sets the exact schedule for your account.

The reason the timeline is short is what's missing from it. Carrier SMS programs sit in A2P 10DLC registration first: brand registration, campaign review, and carrier approval, a process that commonly runs one to four weeks end to end, stretching to three to six weeks for full approval across every major carrier, with each rejection and resubmission adding roughly five to ten business days. None of that applies to iMessage, so the waiting period it creates does not exist here.

What does have to happen is activation. Your dedicated number gets stood up with your chosen area code, your CRM gets connected, and your first messages get written with you. That work is done for you as part of white-glove setup, and it is why a speed-to-lead workflow can be live and wired before a single lead hits it.

From there, the first send is a decision rather than a wait. There is no waiting period between activation and sending: no carrier campaign forms, no vetting queue, nothing pending on a third party. Teams running time-sensitive plays go live fastest, and your first inbound lead can get a blue bubble on the day the line goes live.

The honest caveat: every account's schedule depends on how ready your list, your CRM access, and your first campaign are. That is exactly what the onboarding call pins down, so book the call and you'll leave it with dates.
