Short answer
During Downtime, only the people you allow can call, FaceTime or message you, unless you set Communication Limits to Everyone. On iOS 26, go to Settings > Screen Time > Communication Limits > During Downtime and choose Specific Contacts. On iOS 27, where Downtime is now Screen Time Schedule, go to Settings > Screen Time > Communication Limits > When Device Paused or Unavailable and choose Always Allowed, then add people in Settings > Screen Time > Always Allowed > Add People.
During Downtime, only the contacts you allow can call, FaceTime or message you, unless you set it to Everyone. You choose them in Settings > Screen Time > Communication Limits: on iOS 26, tap During Downtime and pick Specific Contacts. On iOS 27, Downtime is now called Screen Time Schedule, and the option is When Device Paused or Unavailable, set to Always Allowed.
Below are the exact steps for iOS 26 and iOS 27, what happens to calls and messages from everyone else, and how to keep the list short enough to mean something. Every menu name was checked against Apple’s iPhone User Guide on October 26, 2026.
Who can reach you during Downtime?
It depends on one setting. This is what each choice means, from Apple’s Communication Limits pages:
| Communication Limits setting for Downtime | Who can call, FaceTime or message you |
|---|---|
| Specific Contacts (iOS 26) or Always Allowed (iOS 27) | Only the people you picked. Everyone else’s calls and messages don’t go through. |
| Everyone | Anyone, including unknown numbers. Downtime doesn’t limit calls or messages. |
| Left unchanged (iOS 26) | The During Downtime setting starts as whatever you chose for During Screen Time: Contacts Only, Contacts & Groups with at Least One Contact, or Everyone. |
| Emergency numbers | Apple’s Screen Time guide for Mac says “Communication to known emergency numbers is always allowed.” Apple’s iPhone Communication Limits pages don’t repeat that line. |
A phone boundary can be useful until it cuts across the one thing you actually need to hear from.
Maybe you want social feeds to wait while you work, eat dinner, or wind down. But you still want a call from your partner to come through. You may need to hear from a child, a caregiver, a manager, or the person meeting you somewhere. The answer is not to leave every messaging or social app open just in case.
It is to separate people you need to reach from apps that tend to pull you away.
Apple’s Screen Time tools give those two questions different places. A Screen Time Schedule (called Downtime in iOS 26) can set which apps are available for a period you choose. Its Communication Limits settings let you decide who can communicate with you during that boundary. That means you can make room for a protected hour without treating every contact, or every app, as the same kind of access.
Can people call me during Downtime?
Yes, if you allowed them. People on your allowed list can call and FaceTime you as usual. For everyone else, Apple says that if someone who’s blocked by your Communication Limit settings “tries to call you or send you a message, their call or message won’t go through.”
It works the other way too. If you try to call or message someone who’s blocked, Apple says their name or number appears in red in your recent calls or messages. On iOS 26, Apple adds that when the limit applies only to Downtime, you get a Time Limit message and can reach the contact again when Downtime ends.
Apple’s pages list what counts as communication: incoming and outgoing phone calls, FaceTime calls, and messages, with contacts saved in iCloud. If Contacts isn’t turned on in iCloud, Apple says to turn it on first in Settings > [your name] > iCloud: tap See All next to Saved to iCloud, then turn on Contacts.
Do messages come through during Downtime?
Messages from allowed contacts do. Messages from people you haven’t allowed don’t go through, the same as calls. Apple’s iOS 26 guide puts it in one line: “During downtime, only calls, messages, and apps you choose to allow are available.”
Apple’s Communication Limits pages talk about phone calls, FaceTime and messages. They don’t mention third-party messaging apps like WhatsApp. Those follow the app side of Downtime: if the app isn’t allowed, it’s unavailable during that time like any other restricted app. That’s why the app list and the contact list are separate decisions, more on that below.
What is a Downtime contact?
A Downtime contact is someone you’ve allowed to reach you while Downtime or a Screen Time Schedule is on. In iOS 26 you pick them as Specific Contacts under During Downtime, or under Always Allowed > Contacts. In iOS 27 they’re the people in Always Allowed.
Apple’s own example is family. The iOS 27 guide says “you may want to add family members or the Health app to Always Allowed for emergencies.” Always Allowed covers more than Downtime: Apple says those contacts and apps stay available “at all times, regardless of any Screen Time schedules or Time Allowances you’ve set.”
Start with the communication path, not the app list
Before changing a setting, name the real reason you are hesitating to create the boundary.
Is it that you need directions? That is an app-access question.
Is it that someone may need to call or message you? That is a communication question.
They may lead to different exceptions. The point is not to build the largest possible list of things that remain available. It is to keep the necessary path clear while the familiar detours wait.
Apple’s Screen Time Schedule guide describes a Screen Time Schedule as time windows that manage which apps you can use at different times of the day. It also documents the option to keep selected apps and contacts available. That distinction is worth preserving. A transit app, a work tool, and a person you need to hear from are not interchangeable reasons to leave a feed open.
Try writing the boundary in one ordinary sentence:
“During the first part of my workday, social apps can wait. Calls and messages from the people I need to hear from can still reach me.”
You are not promising that every moment will be interruption-free. You are deciding what kind of interruption deserves an exception.
How do I allow contacts during Downtime on iOS 26?
- Go to Settings > Screen Time. (For a child, tap the child’s name.)
- Tap Communication Limits, then During Screen Time, and pick who can reach you outside Downtime: Contacts Only, Contacts & Groups with at Least One Contact, or Everyone.
- Tap Back, then tap During Downtime.
- Change it to Specific Contacts, then tap Choose From My Contacts to pick people, or Add New Contact to add someone new.
You can also do it from Settings > Screen Time > Always Allowed > Contacts, which offers the same Specific Contacts choice. Apple describes Always Allowed as contacts you can communicate with “at all times (for example, in the event of an emergency), even during downtime.”
How do I allow contacts during Screen Time Schedule on iOS 27?
Apple’s Communication Limits guide explains the native setting for calls and messages. In iOS 27, Downtime is now Screen Time Schedule, and the steps changed:
- Go to Settings > Screen Time > Communication Limits.
- Tap When Device Paused or Unavailable, then choose Always Allowed (only the people in your Always Allowed list) or Everyone.
- Go to Settings > Screen Time > Always Allowed and tap Add People. To remove someone, tap Edit.
During Screen Time kept its name and its three choices: Contacts Only, Contacts & Groups with at Least One Contact, or Everyone. Apple describes the iOS 27 option as the time “when your devices are paused” and links it to the Screen Time Schedule page. You can see who’s allowed from inside a schedule, too: open a Time Window in Screen Time Schedule and tap Always Allowed. For every other renamed setting, see the full list of iOS 27 Screen Time changes.
The exact labels can vary with your iPhone software, so check the current Screen Time settings on your device rather than relying on an old screenshot. The useful decision stays the same:
- Set the time window you want to protect.
- Decide which people genuinely need a clear way to reach you in that window.
- Keep that list small enough that it still means something.
- Review the apps you are allowing separately.
This is not a ranking of who matters most. It is a practical rule for a particular time. Someone can be important to you and still not need to reach you during the first 45 minutes of work. Someone else may be coordinating school pickup, a delivery, care, or the day’s plan. The list should fit the moment, not become a referendum on your relationships.
Can someone change the allowed contacts without me knowing?
Anyone holding the phone can, unless the settings are locked. A Screen Time passcode stops changes to your limits and schedules, and on a child’s iPhone it’s what keeps the contact list in place. Here’s how to set, change or reset the Screen Time passcode.
On iOS 26, the passcode also unlocks Block at Downtime, which makes restricted apps impossible to open during Downtime instead of showing a reminder you can skip. That setting affects apps, not calls. Here’s what Block at Downtime does, and what changed in iOS 27.
Should you leave a messaging app open just in case?
A common move is to keep a whole messaging or social app available because one person might contact you there. That solves the uncertainty by reopening the thing you were trying to pause.
Before doing that, ask two simpler questions:
- Does this person need to reach me during this window, or do I just dislike the possibility of missing something?
- Is calls-and-messages access enough, or do I truly need a particular app for a concrete reason?
Sometimes the honest answer is that you do need an app available. A boundary is not a test of toughness. But name the reason before you make the exception. “I might want to check” is different from “I need the transit ticket for this ride” or “this conversation is how we coordinate care today.”
That small distinction keeps a useful plan from quietly turning into an empty one.
If you are still choosing the basic shape of the boundary (an all-day limit or one protected window), start with that decision first. Communication exceptions work better once the time boundary itself makes sense.
Can an app blocker choose who reaches you?
Not Calma. This article is about Apple’s native communication controls. Calma does not choose your contacts or manage who can call or message you. For the same question inside a Focus, see how to keep selected people reachable during a Focus.
We make Calma, so weigh this with that in mind. Its role can stay plain: connect Calma to Screen Time and choose the apps you want to restrict. During a scheduled Moment, opening a resting app shows “[App] is resting.” with one button, Back to calm. Screen Time is where the contact setting belongs. Calma is iPhone only, needs iOS 18 or later, and blocking needs Calma Pro, with a 3-day free trial for eligible new subscribers.
That distinction is useful because it stops you from looking for one giant switch that manages every kind of access. A good boundary often has layers:
- a time window that fits the day;
- an app list that identifies the reflex detours;
- a small set of people who need a way through;
- room to revise the plan after you use it.
You do not need to configure every layer perfectly before trying the first one. Begin with the boundary you can explain. If a real need appears, adjust the relevant layer instead of abandoning the whole idea.
Let the weekly rhythm come first
The contact question usually comes after the calendar question.
If your workdays and days off need different schedules, build that weekly pattern before adding exceptions. Once you know which windows are actually worth protecting, it becomes much easier to decide who needs to reach you during each one.
A large exception list is often a sign that the window is too broad, badly timed, or trying to do too much. A smaller one can be a sign that the boundary is finally specific enough to live with.
Keep the people you need reachable. Let the apps that only want a second of your attention wait. That is not an airtight system. It is a clearer one.
