There is no one-key import from Vonage, and Unitpost doesn't port numbers in. You get new numbers or Sender IDs, and in the US you register your brand and campaign with Unitpost (10DLC or toll-free verification), which the carriers review before you can send. Import your contacts with their phone numbers and record the consent you already hold, opt-outs included, so nobody who texted STOP to your Vonage number hears from the new one. Then change the send call to POST /sms and point delivery callbacks at Unitpost webhooks (sms.sent, sms.delivered, sms.failed; replies arrive as sms.received). Keep Vonage sending until the new sender is approved and live. ## FAQ ### Does Vonage handle STOP replies automatically? Not by default. Vonage's Opt-Out Assist handles STOP and HELP once you turn it on (free for 10DLC, a monthly fee for short codes), and US carriers enforce STOP on toll-free numbers themselves. On Unitpost, STOP and HELP are handled on every send, and marketing texts also need consent on record and respect the recipient's quiet hours. ### Does Vonage have SMS campaigns? Not any more. Vonage retired Proactive Connect, its lists and campaigns product, and the Messages API has no send-time field. Unitpost has SMS templates, topics, segments and scheduled campaigns on every paid plan. ## Related - [Sinch SMS alternative](https://www.unitpost.com/alternatives/sinch): How Unitpost compares to Sinch for SMS — per-country pricing, sender registration, compliance, and where Sinch is still the better choice. - [Plivo SMS alternative](https://www.unitpost.com/alternatives/plivo): How Unitpost compares to Plivo for SMS — per-country pricing, sender registration, compliance, and where Plivo is still the better choice. - [Resend alternative](https://www.unitpost.com/alternatives/resend): How Unitpost compares to Resend — pricing, free tier, API design, and where Resend is still the better choice.
