Parents' guide — SOS & emergency

A parent's guide to SOS and emergency contacts (2026)

Every phone can call for help, but most parents never set up the emergency features that come built in. This guide shows you how to turn on Emergency SOS, add emergency contacts and fill in a Medical ID on both Android and iPhone, and it is honest about the one thing a family SOS button does not do: it alerts you, not the emergency services.

If you need help right now

If your child is in danger, ring 999 and ask for police, ambulance or fire. You do not have to wait before reporting a missing child in the UK — that is a point UK police make often.

Every phone can dial emergency services from its lock screen, without the PIN or the fingerprint. On an iPhone the lock screen shows the word Emergency at the bottom. On most Android phones it says Emergency call. Your child can tap it and dial 999 even if they cannot remember the passcode. It is worth showing them this once, calmly, so it is not a surprise on a bad night.

For a worry that is not an emergency, Childline is on 0800 1111 for your child, any hour, free and confidential. The NSPCC is on 0808 800 5000 for you, the adult. Outside the UK, call your local emergency number or your country's child helpline.

The short answer

Set up two separate things, because they do two separate jobs. First, the phone's own Emergency SOS and emergency contacts — these can call 999 and text your location to the people you choose. Second, a family line such as Safeinest's SOS button, which alerts you and the other parents fast but does not reach the emergency services.

Keep the difference clear in your child's head. 999 is for police, ambulance and fire. The family SOS is for "come and get me". Both matter, and neither replaces the other.

Step by step: the phone's own emergency features

Do this with your child watching, on their phone, so they know where the buttons are before they ever need them.

On an iPhone

1. Open Settings → Emergency SOS. Turn on Call with Hold and Release or Call with 5 Button Presses, so holding the side button and a volume button starts a 999 call.
2. Open the Health app, tap the profile picture, then Medical ID. Fill in allergies, conditions and emergency contacts, and switch on Show When Locked.
3. Still in Medical ID, turn on Share During Emergency Call, so a 999 call also sends your location to your emergency contacts.

On an Android phone

1. Open Settings → Safety & emergency (on a Samsung it may read Settings → Safety and emergency).
2. Tap Emergency SOS and turn it on, so pressing the power button several times calls for help and can message your contacts.
3. Tap Emergency contacts and add yourself and one other trusted adult.
4. Tap Medical information, fill it in, then check that it shows on the lock screen.

On both phones, show your child the Emergency word on the lock screen and let them see that it dials 999 without unlocking. Knowing it is there is half the value.

What the built-in tools do — and where they stop

The phone's Emergency SOS is genuinely useful. It can call 999 fast, and it can text your chosen contacts with a location. Medical ID on an iPhone and Emergency information on Android let an ambulance crew, or a kind stranger, see allergies and a contact without unlocking the phone.

Google Family Link and Apple Screen Time are both free and do limits, filters and location well. But neither has an emergency button of its own, and neither gives you a line to your child that survives the phone being left on silent. That is the gap a family line is meant to fill.

Where Safeinest helps — and where it cannot

Safeinest has a family line built in on both Android and iPhone. The child's app has an SOS button that alerts every parent phone at once and writes a permanent line into the family chat, so a missed notification does not lose it. Family calls ring on a locked phone — a full-screen ring on Android, and through Apple's CallKit on an iPhone — and family messages go both ways. None of it needs a phone number, a SIM or credit; it works over the internet, so it also works on a tablet. There is more on this in family calls and messages.

Now the honest limits, plainly. The SOS button alerts your family, not 999 — for police, ambulance or fire your child still dials the emergency number. Both phones must be online; if a device is off or out of signal, the alert lands the moment it is back. On some Android phones two settings decide whether the ring and the alert ever happen: battery optimisation must be off for the child's app, and its notification style must be "Alerts", not "Silent". On an iPhone, Safeinest cannot read your child's other messages — no app can. The full picture is on our features page.

The numbers

Why an easy way to reach a parent matters:

A phone in a pocket is only a lifeline if the child knows how to use it in a hurry, and if the line they reach for is the easy one. That is worth a few minutes of setup tonight.

What to say to your child

Keep it simple and calm:

"If you are ever scared or in danger, you have two buttons. 999 is for police, ambulance or fire — you can dial it from the lock screen without the passcode. The family SOS tells me, and gets me to you fast. You will never be in trouble for using either one. I would rather you press it a hundred times for nothing than not press it the one time that counts."

If this is a brand-new phone, it is worth agreeing on day one — more on that in the first week with a first phone, and there is a calm way to talk about location in how to talk about location sharing.
