Two ways to run SMS on VocUI
Most customers should use Managed SMS. If you are already on Twilio or need wider country coverage, BYOC is still fully supported.
Managed SMS
$15/mo + usage · No Twilio account
- One click to subscribe — no carrier portals
- VocUI submits your 10DLC paperwork for you
- STOP / HELP compliance built in
- Single bill from VocUI, no separate carrier invoice
- US, UK, and Canada numbers
BYOC Twilio
Bring your own Twilio account · Pay Twilio directly
- Use a Twilio account and numbers you already own
- You manage 10DLC in the Twilio Console
- More control over sender pool and routing
- Two invoices — VocUI for the platform, Twilio for messaging
- Anywhere Twilio sells numbers
STOP and HELP answered automatically
TCPA and US carrier rules require specific responses to opt-out and help keywords. VocUI handles every one of them for you — and it never costs an AI credit.
STOP auto-unsubscribe
Recipients who text STOP, UNSUBSCRIBE, CANCEL, END, QUIT, or OPTOUT are opted out instantly. Further outbound is blocked.
HELP templated reply
HELP returns the response from your 10DLC registration, or a sensible default for UK and Canada. No configuration required.
Zero AI credit burn
Compliance replies are templated, not generated. They never hit your AI provider and never count against your chatbot usage.
TCPA on by default
Opt-out records are persisted and respected across every number on your account. Nothing to configure, nothing to forget.
Common questions about Managed SMS
Do I need a Twilio account to use Managed SMS?
No. VocUI owns the Telnyx relationship and handles everything — carrier registration, number provisioning, billing. You get a number and start sending. If you already pay Twilio, BYOC Twilio is still supported as a separate path.
How long does US 10DLC take?
Brand approval typically arrives in 1–3 business days and campaign approval in 24–48 hours after that. You can provision a UK or Canada number in parallel and start sending internationally immediately while the US registration runs in the background.
Can I port my existing phone number?
Managed SMS provisions new numbers only. If you need to port an existing number you own, use the BYOC Twilio path instead — it supports number porting through the Twilio Console.
What happens if I cancel the add-on?
Your number is released at the end of the current billing period. Opt-out records (STOP list) are preserved for compliance. If you resubscribe later, you will need to pick a new number.
Can I send to countries other than US, UK, and Canada?
Not through Managed SMS right now. Those three countries are the only supported destinations. For wider geographic coverage, use BYOC Twilio, which works anywhere Twilio sells numbers.
How do overages work?
After your 250 included outbound messages, you pay per segment: $0.015 for US and Canada, $0.095 for international destinations. A typical short reply is one segment; messages over 160 plain characters (or 70 with emoji) count as two or more. Inbound messages are always free. There is no hard cap, though the international circuit breaker will flag unusual spikes.
