A missed call text back is an automatic SMS sent when your business cannot answer a call. It can acknowledge the call and give the caller a way to respond while someone follows up. Keep the message factual, check the applicable rules and never treat the call itself as permission to send marketing.

Key facts
- Australian commercial SMS generally requires consent, sender identification and a working unsubscribe. ACMA, avoid sending spam, accessed 12 November 2026.
- Promotional content or a link to promotion can make an otherwise factual message commercial. ACMA, January to March 2026 report, published August 2026.
- A phone number can be personal information, depending on whether a person is identifiable. OAIC, what is personal information?, accessed 12 November 2026.
How does missed call text back work?
A phone service detects an unanswered call and triggers a prepared SMS to an eligible caller number. The caller can reply if the sending number supports replies. Your team then reads the response and decides what to do.
For example, a fictional electrician misses a call while on a job. An approved message says: “Hi, this is Example Electrical. Sorry we missed your call. Please reply with your name and a suitable time to call you back.” The owner sees the reply and calls when available. This example is a service acknowledgement, with no offer or promotional link. Whether any message complies depends on its content and circumstances.
An acknowledgement is not a booking or a quote. Do not promise a response time unless your team can meet it. Tell callers to contact emergency services when relevant, and do not rely on an automated text for urgent requests.
How do you set it up?
- Check your current phone service. Ask whether it detects missed calls, can send SMS from your business number and supports incoming replies. Check compatibility with your call forwarding and voicemail.
- Choose a narrow trigger. Decide which business line and hours are covered. Exclude withheld or invalid numbers, and check how the service handles repeat calls so it does not send a stream of messages.
- Write a factual message. Identify the business, acknowledge the missed call and explain how the caller can respond. Leave out offers and promotional links. Get advice about your circumstances before sending if the message’s classification is unclear.
- Assign a person to replies. Choose who monitors the inbox, when they check it and how unanswered replies are handed over. Keep a manual callback process for delivery failures.
- Test using numbers you control. Try an unanswered call, a voicemail, a repeated call and an after-hours call. Check the actual text, delivery, replies and the absence of duplicate messages. Confirm that a call you answer does not trigger a missed-call text.
- Review the workflow. Check message logs and missed replies, fix errors and pause the automation if it sends to the wrong people or replies go unseen.
Check the provider’s pricing and contract before signing. Ask about message fees, volume limits, number ownership, support, data storage and how to turn the automation off. Some services use a branded sender ID that cannot receive replies, so verify the actual reply path. ACMA notes that alphanumeric sender IDs generally cannot receive return messages in its spam guidance.
Can you include an offer in the text?
An offer or promotional link can make the message commercial, even if the rest is a factual acknowledgement. ACMA recommends keeping service messages separate from promotional content. Its 2026 report explains the distinction.
For commercial messages, check consent, identify the sender and provide a working unsubscribe in line with the rules. Do not add missed callers to a marketing list simply because they called. Keep evidence of any marketing consent and honour withdrawals. The ACMA guide explains consent and unsubscribe requirements. This is general information, not legal advice; seek advice for your particular workflow.
What should you do with caller details?
Keep only the details you need to respond, limit staff access and agree how long records are kept. Check the provider’s privacy terms, storage locations, security and deletion arrangements before connecting your phone system. A phone number may identify a person, and your privacy obligations depend on your business and circumstances. See the OAIC’s guidance on personal information.
Do not ask callers to text sensitive information. If a caller sends it anyway, use your normal secure handling process and move the conversation to a suitable channel.
Is a text enough when you miss a call?
An SMS can acknowledge the call, but it does not resolve the enquiry unless someone handles the reply. If callers need immediate answers, compare it with the options in our AI phone answering guide.

Frequently asked questions
How much does missed call text back cost?
Costs vary by provider and plan. Ask about setup, monthly fees, message charges and any number or integration costs before committing.
How do I set up an automatic text message for missed calls on my iPhone?
Check your phone carrier or business phone provider for a missed-call SMS feature. If it does not offer one, compare a suitable business phone service or automation tool and test it with your own numbers.
Does a missed call give me permission to send marketing texts?
Do not assume it does. A missed call alone is not a safe basis for marketing consent. Check ACMA guidance and keep records of valid consent before sending commercial messages.
Does missed call text back need AI?
No. A fixed message triggered by a missed call can work without AI. Someone still needs to monitor replies and follow up.
