Overview
iMessage is Apple's built-in messaging service. Because it comes pre-installed on every Apple device, many parents don't think of it as an app that needs safety attention. However, it supports group chats, photo/video sharing, and contact with anyone who has the child's phone number.
How children use it
Children use iMessage for daily texting with friends and family, sharing photos and videos, sending stickers and Memoji, and joining group chats that can include classmates, teammates, or extended family. Many treat group chats as the social hub of their friendship group, joining and leaving freely. Older children use iMessage to share homework notes, plan meet-ups, and forward content from other apps. Because it is the default green-bubble-vs-blue-bubble divider in UK schools, some children also feel social pressure to be part of every active chat, even when conversations become unkind or move into the early hours of the morning. Inside a conversation they can also share their live location with the people in it, for a set time or until they stop sharing, and use Check In to let a friend or parent know they have arrived.
Main risks
Recommended privacy settings
Filter Unknown Senders
Location: Settings > Messages > Filter Unknown Senders
Set to: On
Separates messages from people not in your contacts into a separate list.
Share Name and Photo
Location: Settings > Messages > Share Name and Photo
Set to: Contacts Only

Communication Safety
Location: Settings > Screen Time > [child's name] > Communication Safety
Set to: On
Blurs photos and videos with detected nudity and warns children before they are viewed or sent in Messages (from iOS 27 it also covers gore and violence). Apple says it is on by default for children under 18 on current software (the age varies by country or region), and in the UK also for adults who haven't confirmed their age. To manage it from your own device your child needs a Child Account in your Family Sharing group.

Myths & facts
Myth: iMessage is just texting — it doesn't need setting up like a social app.
Fact: Because it's pre-installed, iMessage escapes the scrutiny other apps get, yet it carries group chats, photo and video sharing, and messages from anyone who has the number. The few settings that matter — Communication Safety, Filter Unknown Senders, Screen Time communication limits — take minutes and are easy to miss.
Myth: Only people we know have my child's number, so strangers can't reach them.
Fact: Numbers travel: every group chat exposes the number to everyone in it, and once passed on, anyone can message your child or add them to a new group. Filtering unknown senders helps, but assume the number will spread further than you intended.
Myth: Apple's encryption means my child is safe on iMessage.
Fact: Encryption protects messages from outsiders, not from what's inside them. The real problems on iMessage — group-chat pile-ons, exclusion, pressure to share images, chats running past midnight — happen between children who know each other, with no moderator watching.
Age by age
- 8-10
If this is their first Apple device, set it up with a Child Account through Family Sharing so Communication Safety is on and you manage who they can contact via Screen Time's communication limits. Their first group chats are the training ground — practise leaving a chat that turns unkind.
- 11-13
Group chats become the social hub at secondary school. Keep Communication Safety on, ask casually who's in their main groups, and agree device-free nights, because these chats run into the early hours. Talk through what to do when a group turns on one child: don't pile on, screenshot, leave, and tell an adult.
- 14-16
Keep Communication Safety on through Family Sharing — it still works for teenagers and warns before sensitive images are viewed or sent. This is also the age to say plainly that sexual images of anyone under 18 are illegal in the UK even when self-taken, and that being added to large groups full of friends-of-friends deserves the same caution as a stranger's DM.
- 17-plus
Settings give way to habits: talk about forwarding — passing on someone else's photo or message is an act with consequences — and about scam and phishing texts, which is where Filter Unknown Senders still earns its keep. From here your role is being the person they'd show a worrying message to.
