Call2SMS is run by Steony Ltd. When you miss a call, its AI texts the caller within seconds in your business name, holds a short SMS conversation to capture the enquiry and sends you a summary and transcript by email, WhatsApp or SMS. It works through call forwarding on your existing number, so there is no new phone or hardware.
Plans are £37, £67 and £97 a month, metered by recovered-lead conversations (36, 135 and 225). The middle plan adds WhatsApp alerts, urgent-lead alerts and taking over a conversation from the dashboard. Every plan is monthly rolling with a 7-day free trial. Busy months can be topped up with pay-as-you-go credits.
I build and run one system for owner-run UK local businesses. A Voice AI receptionist answers, any call that slips through gets a missed call text back. The conversation is then booked into your calendar. Behind it sit reminders, follow-up, review requests and past-customer reactivation. Core is £297 a month, month to month.

Yes. Call2SMS starts at £37 a month and Vantage Core is £297. They are different purchases. Call2SMS catches the missed call and hands you the lead. Vantage answers, texts back, books, follows up and asks for the review. I run it for you.
Its site describes capturing the enquiry and sending you a summary to act on. I did not find calendar booking listed on its site when I checked on 6 October 2026. Ask Call2SMS directly if that matters to you.
Yes. Both work with your existing number. If you outgrow ringing every lead back yourself, the audit call will show whether the full system pays for itself.
I did, David Barroso, founder of Vantage Growth Partners. I am one of the two options on this page, so read it with that in mind. Every Call2SMS fact links back to its own site, checked on 6 October 2026.
