What is instant SMS reply?

Your phone replies for you, automatically

When you are on site, in a meeting or simply busy, missed calls happen. The problem is not the missed call itself, it is what happens next. Most callers do not leave a voicemail, and most do not call back. They ring the next number on their search results.

Instant SMS reply solves this. The moment a call goes unanswered, TextBack Pro detects it and sends a personalised text message to the caller within seconds. They know you are aware of their call, and they have a way to tell you what they need without waiting.

The result: you recover leads that would otherwise have gone cold before you even knew they called.

How it works

Three steps, zero effort from you

A call comes in and goes unanswered

A customer calls your business number. You are on site, on another call or simply unavailable. The call is not answered.

TextBack Pro detects the missed call via call divert

You set up a simple call divert on your existing number (we walk you through it in under 5 minutes). When a call goes unanswered, it diverts to TextBack Pro, which detects it instantly.

An SMS is sent to the caller within seconds

TextBack Pro sends your personalised SMS template to the caller from your dedicated UK number. They receive it within seconds, typically before they have even put their phone down.

Why it matters

Six reasons instant reply wins more business

Beat the 5-minute window

Works 24 hours a day

Calls come in evenings, weekends and bank holidays. TextBack Pro replies every time, regardless of when the call arrives.

No app for the caller

The caller receives a standard SMS to their mobile. No app download, no login, no friction, just a message in their texts.

Use your existing number

Personalised message

You set your own SMS template, your business name, your tone, your offer. Every message feels personal, not automated.

Instant SMS reply is a core feature available on all TextBack Pro plans, Starter, Pro and Scale, from £47 per month.

Common questions

Instant SMS reply: your questions answered

The SMS is typically sent within 3 to 5 seconds of the call going unanswered. The exact timing depends on your network operator's call divert speed, but in practice most callers receive the text before they have put the phone down.

No. You keep your existing number and set up a conditional call divert so that unanswered calls are forwarded to TextBack Pro. The SMS reply goes out from your dedicated UK TextBack Pro number. We walk you through the divert setup in under 5 minutes when you sign up.

Yes. You set your own SMS template from the dashboard, your business name, your wording, your tone. You can update the template at any time. If you need inspiration, our SMS template generator tool is free to use.
