Missed Call Text Back
A missed call from a stranger is usually a lost job. Most people do not leave a voicemail, and the ones who do not simply call the next business on the list.
Missed call text back sends that caller an automatic text within seconds so the conversation continues instead of ending. This page covers how it works, whether it is legal, the A2P 10DLC registration you need in the US, why your phone's built-in auto-reply is not the same thing, and a calculator for what your missed calls are worth.
How Missed Call Text Back Works
The setup is three steps and it runs on your existing business number.
Your number is connected to Phanz and continues ringing your phone exactly as it does now. When a call goes unanswered, the system waits for the call to end, then sends the text you wrote. The caller replies, and the whole conversation lands in one inbox with their number attached, which means you have the lead even if they never call back.
A reply that works looks like this: "Hi, this is Dave at Dave's Plumbing. Sorry I missed you, I'm on a job. What's happening and what's the address? Reply STOP to opt out." Your name, the reason, a question, and the opt-out.
Ask a question in the message. "We'll call you back" gets no reply. "What's happening?" gets an answer, and a conversation you can book.
Is It Legal?
Texting someone who just called you is the strongest position in SMS compliance, because they contacted you first and expect a response. The CTIA messaging principles and the general reading of the TCPA treat a reply to a consumer-initiated contact as consented communication.
Where businesses get into trouble is the step after that. Adding the caller to a marketing list and sending them offers for the next six months is a different activity with different rules, and it needs consent you can prove. Keep the automatic reply transactional, and get permission before anything promotional.
Three habits keep you safe: identify your business by name in the first message, include opt-out wording and honour STOP immediately, and respect quiet hours for anything that is not a direct reply. Our terms of use and privacy policy set out the same obligations, and the information security page covers how the messaging side is handled. None of this is legal advice.
A2P 10DLC Registration
Application to Person messaging on a ten digit long code is the technical name for business texting from an ordinary local number. Since carriers started enforcing it, unregistered business traffic gets filtered, delayed or blocked outright, and you often will not be told.
Registration has two parts. Brand registration identifies your business with an EIN or equivalent, and campaign registration describes what you will send, with sample messages and opt-in and opt-out language. Carriers check that your website exists, that it has a privacy policy covering how you use phone numbers, and that your opt-in description matches what the site actually does.
This is the main reason a privacy policy page is not optional for a trade business that wants to text. On Done-For-You we handle the registration paperwork as part of the build. On DIY it is a form you complete once, and approval usually takes a few days.
Why Your Phone's Built-In Auto-Reply Falls Short
Both iPhone and Android can send an automatic message, and for a sole trader it is a reasonable first move. The limits show up quickly.
It only fires in Do Not Disturb or while driving, so it does nothing during the calls you miss because you are up a ladder. It replies to every caller including your family. It cannot vary by time of day. It does not save the caller anywhere, so there is no record of the lead. And when the person replies, the message sits in your personal texts with everything else.
There is also no follow-up. Roughly half the people who reply to a first text go quiet again if nobody answers, and the phone's built-in reply has no way of chasing them the next day.
Stopping Repeat Callers From Getting Three Texts
Someone with an emergency calls twice in a row. If your system texts on every missed call, they receive two or three identical messages in under a minute, which reads as broken software and gets reported as spam.
Phanz checks the number against recent activity before sending. If that caller was already texted inside the window you set, usually somewhere between one and twenty-four hours, no second message goes out. Anyone already in an open conversation is skipped too, so you never interrupt a live thread with an automated line.
Set your window to match your trade. Emergency work suits a short window of an hour or two. Quoted work is better at twelve or twenty-four hours, so a homeowner ringing round on a Saturday hears from you once rather than four times.
Try It on Your Own Phone
Call our demo line on +1 830-289-5489 and hang up. Within a few seconds you will get the text, and if you reply you will get the booking link, which is exactly what your callers would experience.
It costs nothing and it takes twenty seconds. Most people decide on this rather than on anything written above.
What It Costs
Missed call text back is included on every plan. The DIY plan is $98/mo with no setup fee, and you switch the feature on yourself. Done-For-You is $547/mo and we write the message, set the repeat window, register your number and connect the follow-up.
Message sending is billed at carrier rates on top, which comes to a few dollars a month for most trades. Nobody charges you per recovered lead. See the pricing page for the full comparison.

Missed Call Text Back: Common Questions
What is missed call text back?
It is an automatic text message sent to anyone whose call you did not answer. The caller hangs up, and within seconds their phone shows a message from your business number asking what they need. Most people reply to the text, so the enquiry carries on in writing instead of going to a competitor.
Is missed call text back legal?
Replying by text to someone who just called your business is generally treated as answering a contact they started, which is the basis carriers and the CTIA messaging principles use for this kind of reply. The rules tighten once the messages turn into marketing: then you need consent, a way to opt out, and your business named in the message. This is a description of how it usually works rather than legal advice, so check your own position.
Do I need A2P 10DLC registration?
If you are sending business texts to US numbers from a standard ten digit number, yes. Carriers require your brand and campaign to be registered, and unregistered traffic gets filtered or blocked. Registration asks for your business details and a website with a privacy policy that covers messaging, plus sample messages and opt-out wording.
Can I not just use my iPhone or Android auto-reply?
You can, and it is better than nothing. The built-in reply only fires in Do Not Disturb or while driving, it goes to everyone including your mother, it does not record the lead anywhere, and nothing follows up afterwards. It tells the caller you are busy. It does not start a conversation you can win.
What if the same person calls three times?
They should get one message, not three. Phanz checks whether that number has already been texted inside your chosen window, so a repeat caller in the same hour gets nothing extra. That matters because three identical texts in five minutes is the fastest way to be reported as spam.
How much does missed call text back cost?
It is included on every Phanz plan, starting at $98 a month for DIY. Message sending is charged at carrier rates on top, which for a small business handling a few hundred texts a month is usually a few dollars. There is no separate fee for the feature.
Does an AI answer the messages?
The first reply is a message you wrote, sent automatically. From there you can answer by hand from the conversations inbox, or set up automated question and booking flows. Most trades start with the automatic first reply and a human answering after that, because it reads better and it is easier to get right.
