Set up missed-call text-back for your business

The short answer

Three levels. The free one is a habit: save a short reply ("Sorry we missed your call, text back or book: link") and send it by hand whenever the phone rings out; iPhones can send it from the decline screen. The proper fix is a virtual business number in front of your mobile, with a provider whose system texts missed callers automatically, as SwitchboardFREE's Callback SMS does. Or keep your number and divert unanswered calls to a dedicated service such as Call2SMS (from £37 a month), whose AI texts back in seconds and captures the enquiry. Whichever you choose, test it from a mobile and from a landline.

Why a text beats your voicemail

Most people who ring a small business and get no answer don't leave a voicemail. They're standing next to a dead car or a leaking tank with a phone in their hand, and the same search that found you found three more garages or plumbers below you. The next number down gets the job, and you often never know the call happened.

A text within a minute changes that. The caller is still holding their phone when "Sorry we missed your call, reply here or book" arrives, so you now exist in their messages with a link, not just in a list of numbers that didn't answer. Replying to a text takes less nerve than ringing twice, and the booking link still works even if they've already started dialling your competitor.

Everything below builds the same thing three ways: by hand for nothing, automatically with a virtual number, or as a paid service that also captures the enquiry. Trades, salons and garages are exactly who this is for, because your hands are busy when the phone rings.

1. Write the message once

All three setups send the same text, so write it first. It needs four things: an apology, your business name, a way to reply, and one link where the caller can act. Sign it with a real first name; "Kerry" gets replies that "The Team" doesn't.

Point the link at a page where someone can actually do something on a phone: your online booking page if you have one, otherwise a contact page with prices and opening hours. And only promise what's true. If you can't reply until you're off the tools at five, don't say "back to you in ten minutes"; the text is a promise, and breaking it is worse than the missed call.

One boundary worth keeping: this text is a reply to someone who just rang you, so keep it about their call. Don't quietly add the number to a marketing list off the back of it; that's a different set of rules and a fast way to look spammy.

Sorry we missed your call to Kerry's Salon. Text back what you
need, or book direct: kerryssalon.co.uk/book. I'll reply as soon
as I'm free. Kerry

2. Start free: a saved reply sent by hand

The zero-cost version is a habit, not a product. Keep the message saved where you can paste it (your notes app, or a keyboard text shortcut) and send it to every number you couldn't answer, there and then if you can, or the moment you next pick the phone up.

iPhones build half of it in. When a call comes in that you can't take, tap Message and choose a reply, and you can set your own wording under Settings > Apps > Phone > Respond with Text, which is where Apple's iPhone guide says the default replies live. Most Android diallers have an equivalent quick-reply option somewhere in the phone app's settings; where it sits varies by handset.

Its limit is obvious: it only fires when you see the call and act, and the expensive misses are the ones that ring out while the phone's in the van or your hands are in foils. Treat this as the version you start today, not the version you stop at.

3. A virtual number that texts back by itself

The proper fix takes you out of the loop. A virtual business number (01, 02, 03 or 07) sits in front of your real phones and rings them however you like; when nobody answers, the provider's system sends your text to the caller, every time, with no memory required.

Some UK providers do this off the shelf. SwitchboardFREE calls it Callback SMS: when a customer's call is missed, they receive your bespoke message once they hang up, a short apology with a link to your website or a note that you'll get back to them. Others have the ingredients without the automation. CircleLoop, another UK-built system, lists instant 01, 02, 03 and 07 numbers and SMS from 4p a message (UK only) on its features page, but no automatic missed-call text, which is why you put this exact question to any provider before signing:

Once it's live, make the virtual number the one the world sees: Google Business Profile, the website, the van, the shop window. Calls still reach your mobile because the number forwards there; the difference is that the ones you miss no longer disappear.

When a call to my number goes unanswered, does your system
automatically text the caller from my business number, and can
I set the exact wording?

4. Bolt a dedicated service onto the number you have

If a new number feels like too much surgery, dedicated missed-call text-back services sit behind the number you already advertise. Call2SMS, a UK service aimed squarely at trades, garages and salons, keeps your existing number: you set up conditional call forwarding so only unanswered calls divert to it (they walk you through the divert when you sign up), or they'll assign you a fresh UK number if you'd rather.

What you're buying is the conversation after the first text. Call2SMS texts the caller back within seconds in your business name, then its AI holds a short SMS exchange, asks what they need and how urgent it is, and sends you a summary with the full transcript, by email on the entry plan and by WhatsApp and text as well on the bigger ones. Plans start at £37 a month for 30 of those recovered conversations, with a 7-day free trial, no contract, and opt-out handling built in.

Whether that's worth it depends on who your missed callers are. If they're mostly regulars who'd have texted you anyway, the virtual-number route above does the job for less. If they're new enquiries you'd otherwise never hear from again, one captured job a month probably covers the fee; do that sum with your own prices, not mine.

5. Test it like a customer, twice

First the mobile test. Ring your business number from your own mobile, let it ring out, and watch what happens: the text should arrive within a minute, the link should open somewhere useful on a phone screen, and a reply to the text should land where someone will actually see it. Then reply with an awkward question and check what comes back, especially if an AI is answering in your name.

Then the landline test, and this one matters for garages and trades in particular, because plenty of older customers still ring from a house phone. A text sent to a landline number can't arrive the way it does on a mobile; depending on the receiving network it may be read out by an automated voice call, turn up garbled, or go nowhere at all. So ring your business from a landline, miss the call on purpose, and find out what your setup actually does. If the answer is nothing, your voicemail greeting is the backstop for those callers, so re-record it to mention the booking link too.

Where this gets hard

The failures are silent, which is what makes this fiddlier than it looks. A withheld number gives the system nothing to text. A landline may swallow the message. A conditional divert that's set slightly wrong means some calls never trigger anything, and the divert itself lives in awkward settings that differ between mobile networks and can quietly come undone when you change handset or SIM. None of it announces itself; the only symptom is a phone that seems quieter than it should be, which is why the test calls in step 5 are the part people skip and shouldn't.

The number decision is the other place DIY attempts stall. Keeping your existing number means living with diverts. Moving the business onto a virtual number means updating Google, the website, the van and years of fridge magnets. Porting a long-standing number into a phone system is a form-heavy process where a mistake can take the number down entirely. None of these is wrong, but picking between them depends on how your calls actually arrive, and most providers will happily sell you whichever one you ask for.

And the text is a promise somebody has to keep. Replies arrive at 9pm, an AI chats in your name and occasionally says something daft, the booking link goes stale after a price change. The automation is the easy half; the routine around it (who watches the inbox, who reads the transcripts, when the wording gets refreshed) decides whether this wins work or quietly annoys people.

What you end up with

• Every missed call answered with a text in your business name, automatically once you're past the free habit
• One short, honest message with a booking link, reused across whichever setup you choose
• Proof from real test calls, mobile and landline, that the text, the link and the replies all work
• A clear upgrade path: saved reply today, virtual number or dedicated service when the missed calls justify it
