How to set up an automatic text reply

Reviewed by Sujan ThapaliyaLast updated

The short answer

iPhone has Driving Focus, which auto-replies only while you are driving, and Focus modes that can reply to chosen contacts. Android varies by manufacturer, with some builds offering scheduled replies. Neither handles business hours properly, which is why a scheduled auto-reply belongs on a business messaging platform.

Phones are surprisingly bad at this. The built-in options were designed for driving rather than for business hours, which is why most people searching for an auto-reply are disappointed by what their handset actually offers.

What can each platform actually do?

The gap between the last two rows is a permissions decision as much as a features one.

How do you set it up on iPhone?

  1. 1

    Open Focus settings

    Settings, then Focus. Driving is the mode with a genuine auto-reply; the others vary by iOS version.
  2. 2

    Choose Auto-Reply and who it applies to

    Recents, favourites, all contacts or nobody. Recents is the sensible default, covering people mid-conversation without messaging your entire address book.
  3. 3

    Write the message

    Short. It is read on a lock screen by somebody who wanted an answer, so tell them when they will get one.
  4. 4

    Decide how the mode turns on

    Automatically while driving, or manually. Automatic is the point: a mode you have to remember to enable is one you will forget on the day it mattered.

Third-party auto-responders read everything

An app that replies to your messages needs permission to read all of them, permanently, including banking codes and private conversations. On a work phone it may also breach policy. That is a large permission for a small feature.

Why is a business auto-reply a different problem?

A driving auto-reply answers one person while you are unavailable for twenty minutes. A business needs a reply on a schedule, different messages inside and outside hours, no reply to people already mid-conversation with a colleague, and a record that the reply was sent.

None of that is a handset feature, and the workarounds are worse than they look: an auto-reply running on one person's phone stops when that phone is off, answers the wrong people, and leaves nothing behind that anyone else can see.

  • Set it by schedule, not by mood — business hours, weekends and holidays decided in advance.
  • Say when, not sorry. A time beats an apology; by 10am tomorrow is something the sender can plan around.
  • Give exactly one urgent route, and make sure it is answered.
  • Do not auto-reply twice. Replying to every message in a thread turns a helpful acknowledgement into an annoyance.
  • Keep promotions out of it. An out-of-hours acknowledgement carrying an offer is a marketing message, with the consent rules that follow.

On a shared business number the same schedule can hand overflow to an AI receptionist or route the conversation into a queue, so an out-of-hours message becomes a booked callback rather than a promise to reply. That is usually what the problem actually needed.

Frequently asked questions

Can an iPhone auto-reply to text messages?
Only in specific circumstances. Driving Focus sends an automatic reply while you are driving, and other Focus modes can auto-reply to selected contacts. There is no general reply-to-everyone-after-6pm setting built into iOS.
How do I set up an automatic text reply on iPhone?
Settings, then Focus, then Driving, then Auto-Reply, and choose who it applies to: recents, favourites, all contacts or nobody. Other Focus modes expose the option in the same place where the iOS version supports it.
Can Android auto-reply to texts?
It depends on the manufacturer. Some builds include scheduled or driving auto-replies in the Messages app settings; others have nothing and rely on third-party apps, which need permission to read every message on the phone.
What should a business auto-reply say?
Three things and no more: that the message arrived, when a person will respond, and one route for anything urgent. Longer than about two lines and it gets skimmed on a lock screen.
Do auto-replies count as marketing messages?
A reply to a message somebody sent you is a response, not an outbound campaign. It becomes something else if it carries a promotion, which turns a service message into a marketing one with the consent obligations that follow.
