First off, a brief caveat: we make a phone for children, so we obviously have skin in the game. As we are parents too, and in 2025 were in the position you're in now - trying to work out which is the best option for our child (there wasn't one, so we built this instead) - we've done our best to keep this guide as even-handed as possible. Below is a summary of the phone types currently available for kids in the UK: the real options, what age most families buy, what actually makes a phone safe for a child, and how to choose the right one. We'll tell you where ours fits, and where it does not - to better inform your decision.
If you searched "kids phone" and felt instantly overwhelmed by the choice, you are not alone. The category has gone from "a brick or a full smartphone, take your pick" to a crowded shelf of watches, curated app phones, monitored phones and pared-back phones, most of them promising the same thing. This guide is here to help you make sense of it all.
Start with two lists, not a shortlist
The mistake most of us make is starting with "which phone?". The better opening question is "what do I want it to do, and what do I want to keep out?".
A phone for a child can be anything from a way to ring you on the walk home to a full pocket computer with the entire internet on it. Those are wildly different decisions, with very different outcomes. So before you compare handsets, jot down two short lists. On one side, the things you want: usually staying in touch, a little independence, knowing where they are. On the other, the things you would rather they did not have yet: social media, an open web browser, an app store, the incessant buzz of notifications, an endless scroll. Starting with clarity on these points will make your decision much easier to get to.
How are other UK parents tackling this?
It helps to know where the herd is standing, because the school gate makes everyone feel like the odd one out.
The tipping point is the move to secondary school. Ofcom's 2025 Children and Parents report finds smartphone ownership jumps from 56% of ten-year-olds to 83% of eleven-year-olds, the year most children start Year 7, and it is near-universal by the mid-teens (Ofcom, 2025). So if your nine or ten-year-old has no phone yet, don't believe them if they tell you they're "the only one in school without one!"
Parents are also more cautious than the playground suggests. In Internet Matters' 2024 research, the average age UK parents considered right for a first smartphone was eleven years and eleven months, and one in four said the minimum should be fourteen or over (Internet Matters, 2024). There is a movement behind that instinct too: more than 150,000 families have signed Smartphone Free Childhood pacts, agreeing with other parents to hold off together (Smartphone Free Childhood, 2026). If your instinct is telling you to continue to hold out, you have a great deal of company.
The deeper dive on timing lives in our guide to what age a child should get a phone.
Phones for kids by age
Treat these as starting points, not rules. Every child is different, and readiness matters more than the number of candles on the cake.
Under 8
Most guidance and most parents agree this is early for a personal phone. If contact is the real need, a basic call-and-text handset or a GPS phone watch does the job without putting a screen in a small pocket. The aim at this age is reachability, not a social life.
8 to 10
The "tween" window, when independence starts creeping in: walking to school, clubs, playdates further afield. Safety and logistics drive the decision here, not group chats. A first phone limited to calls, texts and knowing where they are fits this stage far better than a full smartphone, and it keeps the app and social-media world at arm's length for a while longer.
11 (Year 6 to Year 7)
The big one. New school, new journey, wider circle, and the moment most children get a phone. It is a strong time to give a first phone, and a far riskier time to hand over an unrestricted smartphone, because the social-media and group-chat pressure is at its most intense in exactly this year. For a proper look at this age, see our guide to the best phone for a 10 or 11 year old.
12 to 13
The conversation shifts from "if" to "how much". Messaging apps and social pressure ramp up, and many families widen capability gradually rather than all at once. Worth knowing: thirteen is the UK age of digital consent, and platforms are built to that line, so a supervised account can change character on a child's thirteenth birthday, whether you feel your child is ready or not. We unpack that in what happens when they turn 14.
14 to 16
Closer to where most expert and parent opinion lands for fuller smartphone access, ideally after a few years of building good habits on something simpler. The smart move many families make is to start pared-back and step up on their own timetable, rather than start with everything and try to claw control back.
The main types of kids' phone, in brief
Five broad routes cover almost everything on the UK shelf. For the full, weighed-up version of each, read our objective first-phone buying guide. Here is the short form.
A basic "brick" phone. Think Nokia 105 or a Doro handset. Calls and texts, often a torch, around twenty to thirty pounds, days of battery. Good for younger children and tight budgets. The catch: many children find them isolating once friends move on, and you may be back at this decision within a year.
A GPS phone watch. A wrist device for calls and texts to a short approved list, with location built in. Good when the need is "reach them and know where they are". Limited as they get older, so it tends to have a short shelf life.
A normal smartphone with parental controls. An iPhone with Screen Time or an Android with Google Family Link. Cheapest if you already have a handset, and it grows with the child. The catch: you start with a full smartphone and lock the risky parts away afterwards, the controls sit on top as software a determined child can work around, and you become the family IT department. Limiting screen time alone does not filter content either, so a child can still come across age-inappropriate or antisocial material within the time they are allowed. Our full comparison is in iPhone with Screen Time vs a kids' phone.
An app-curated kids' smartphone. A growing category that still runs apps, but in a managed way. In the UK this includes Pinwheel, the HMD Fuse and OtherPhone. Good for parents who do want some apps with guardrails and expect to move towards a fuller smartphone in time. The catch: it is still an app world to set up and supervise, and once children know that games, entertainment and algorithm-driven apps are possible at all, many will nag until your resolve weakens.
A pared-back first phone. The deliberately simple end, and where Sayph sits. A real phone for calls, texts and a few essentials such as music, maps and location, but with no app store and no open internet. The restrictions are built into the phone itself rather than bolted on. Good for parents who want to keep the first phone simple and delay the app and social-media world for longer. The catch: there is a subscription, and it is not an app phone. If a curated set of apps is what you want, one of the app-curated phones will suit you better, and we would rather say so.
What makes a kids' phone actually safe
Plenty of businesses are claiming to put children first (even Big Tech), and all the products above would put "safe" on the box, so it is worth knowing what to look out for. Here is a checklist you can apply to any phone for kids, ours included.
Are the limits built in, or bolted on? This is the single biggest difference between products. Parental-control software sits on top of a normal phone, which means there are settings a determined child can find and switch off, and a steady stream of workarounds. A phone with the restrictions built into the operating system has nothing sitting on top to unbolt. No device on earth is tamper-proof, but the two approaches are not equally hard to get around.
What is the default: open, or closed? A phone that ships with an app store and open web, then relies on you to lock things down, starts from risk. A phone with no app store and no browser by default starts from safety. Curated phones sit in between, allowing approved apps only. Decide which starting point matches your two lists.
Who can contact your child? Look for approved-contacts-only calling and messaging, so unknown numbers and strangers cannot get through. This matters more than most parents expect, and it is the quiet feature that does a lot of the work.
What does "monitoring" really mean? Read this carefully, because the marketing rarely spells it out. Some phones show you time and access but not content. Others give you message summaries. A few read everything. There is a real line between visibility, which keeps you in the picture, and surveillance, which can corrode trust. Decide where on that line you want to sit, and check the phone actually sits there.
What happens to the data? A child's first phone is the wrong place to build a surveillance habit. Ask how long messages, calls and location are kept, who can see them, whether the company sells data or profiles children, and whether any AI features are barred from training on your family's information. Good answers are short retention, visible only to you, no selling, no profiling.
Does it need a special SIM, or can you bring your own? Some kids' phones tie you to a specific network or a bundled plan. Others let you use any UK SIM, which usually works out cheaper and more flexible. Check before you commit, and if you live somewhere with patchy signal, confirm the plan supports Wi-Fi Calling. Our guide to choosing a SIM walks through data, networks and picture messaging.
Is the safety paid for upfront, or a subscription? And if the subscription stops, will the phone still work? Know what you are committing to over time, not just on day one.
Will it still be right in two years? Children's needs evolve as they grow, and if you choose one of the more open options, it pays to think carefully about each new app before it goes on the phone. Once an app is on the device, you will want to be confident you can keep abreast of what they are doing with it and who they are in contact with. And once a child has the open internet in their pocket, much of the day-to-day responsibility for what they see and who reaches them sits with you.
Where Sayph fits, specifically
Since we make one, it is only fair to show our working rather than plant a logo. Here is how Sayph answers the checklist above, so you can judge it on the detail.
The restrictions are the phone, not an app on top: we reconfigured the operating system, so there is nothing bolted on for a child to find and switch off. There is no app store and no web browser by design, which takes most of the risk and the time-sink off the table rather than trying to police it. Calls and messages are limited to contacts you approve, so unknown numbers do not reach your child. The parent app, Sayph Space, gives you simple summaries of messaging and location, designed to flag what is worth a look rather than hand you a transcript, which is visibility without tipping into full surveillance. The data behind all of it is encrypted, visible only to you and never to Sayph staff, and deleted after a maximum of thirty days; we do not sell data or profile children, and our AI summary provider is contractually barred from training on your family's data. You bring your own SIM from any UK network, and you decide when your child is ready to move on, rather than a birthday deciding it for you.
Sayph is built for ages 8 to 16. The phone is a one-off £189 with free UK delivery, Sayph Space is £4.99 a month and you can cancel anytime, and a SIM from a provider such as Smarty or Giffgaff typically runs about £2 to £3 a month. That is the whole cost, with nothing hidden.
And to answer the checklist's own question: because the restrictions live in the phone, not in an app bolted on top, the handset keeps working even if the subscription lapses. Calls, texts and the locked-down setup all carry on. What the subscription pays for is the parent side, Sayph Space, so if it stops you lose the portal until you restart it, which means no live location or message summaries, no routines, no approving new contacts, and no further updates. The phone stays locked down, and you regain everything the moment you resubscribe.
And the flip side, said plainly: it is a subscription, and it is deliberately simple. If what you want is a full smartphone with apps you manage yourself, an iPhone with Screen Time is the better fit. If you want a curated set of apps with guardrails, one of the app-curated phones is. We built Sayph for the parent who wants to extend the simpler stage, not shorten it.
The cost, counted properly
In pure pounds, a spare handset you already own with free controls is the cheapest route, and we will not pretend otherwise. But count the whole picture. The spare-smartphone route spends your time instead of your money: the ongoing setup, the app requests, the workarounds, and a several-hundred-pound device going to school. A purpose-built phone trades some money for less of your time, a firmer line you are not personally policing, and usually a sturdier, cheaper-to-replace handset. Neither is simply "cheaper". One costs pounds, the other costs hours.
Frequently asked questions
What age should a child get a phone?
There is no magic number, but UK evidence and expert opinion point the same way: most children are ready to be contactable around the start of secondary school, and ready for the full internet rather later. The smart move is to separate those two steps. Full detail in our age guide.
What is the safest phone for a child in the UK?
There is no single safest phone, only the one that matches what you want it to do and keep out. Run any option past the safety checklist above: are the limits built in or bolted on, what is the default, who can make contact, and what happens to the data. That will tell you more than any badge.
Do kids' phones need a special SIM?
It depends on the phone. Some tie you to a network; others, Sayph included, let you use any standard UK nano-SIM from any provider. If signal is patchy where you live, check the plan supports Wi-Fi Calling. See our SIM guide.
How much does a phone for a child cost?
Anywhere from around twenty pounds for a basic handset to several hundred for a full smartphone, plus a SIM, and often a monthly subscription for purpose-built kids' phones. For reference, Sayph is £189 for the phone, £4.99 a month for the parent app, and about £2 to £3 a month for a SIM you buy separately.
Can a child bypass the controls?
On a normal smartphone with bolt-on parental controls, there is a documented supply of workarounds, because the controls sit on top of the phone. Phones with the restrictions built into the operating system are far harder to get around, though no device is tamper-proof. We cover this properly in the iPhone comparison.
Won't my child be left out without WhatsApp?
It is the fear that ends most parents' resolve, and it deserves a proper answer rather than a wave. Being connected is not the same as being in the class group chat, and the group chat carries most of the cost. We look at the evidence in will my child be left out and at what sits behind the icon in WhatsApp and your child.
The bottom line
There is no single best phone for kids, only the right one for your child and your family. Write your two lists, place your child on the age map, match that to the options, and run your shortlist past the safety checklist. Do that and you will make a sound decision whichever way you go.
And if your instinct is that the first phone should be a simple, real phone that holds off on the app store and the open internet for a good while yet, while keeping parents and carers in control, that is the gap we built Sayph to fill. You can see how it works or order today.
