Independence for them, peace of mind for you.

8 to 16. Like Smartphone Free Childhood, we believe that in an ideal world children wouldn’t need phones at all, and that holding off for as long as you can is the right instinct. But when the time comes for your child to stay in touch and have a little independence, that first phone shouldn’t be an open smartphone. Sayph lets you say yes to calls, texts and knowing where they are, without saying yes to social media, an app store or the open internet.

If you’re weighing up the timing, our guide to what age should a child get a phone walks through the UK evidence, and we look specifically at the best phone for a 10 or 11 year old for the move up to secondary school.

Sayph is built to be far harder to get around than standard parental controls. There’s no app store, no default browser, and the operating system itself is restrictive; there are no settings for a determined child to find and switch off. No device on earth is tamper-proof, but unlike bolt-on controls, Sayph’s restrictions are the phone, not an app running on top of it. Only Sayph apps – designed for specific needs, rather than distraction or entertainment – are available.

No. We've heard too many stories about what happens when children are allowed to roam free on social media, and we don't believe the big tech firms can be trusted to safeguard our children. The tech firms have themselves chosen 13 as the age when they want children to start using their products. We believe if governments were serious about prioritising children's mental health and wellbeing, they would ban social media use before 16.

WhatsApp isn’t available on a Sayph phone, and that’s a deliberate design choice. For most children the real risk on WhatsApp isn’t strangers, it’s other children: group chats where any member can add images, videos and messages, and which Ofcom finds are among the most common places children are bullied online. Add disappearing ‘view once’ messages, content that arrives as images rather than searchable text, and end-to-end encryption that hides what’s being shared, and it quickly becomes a child’s whole social world – with all the pressure, exclusion and fallout that brings.

Allowing it would also undermine the things that make Sayph safer: messaging stays between the contacts you’ve approved, stays visible to you in the Sayph Space portal, and isn’t buried under constant notifications. WhatsApp would route your child’s messaging around all of that. We’d rather keep the phone built for staying in touch, not for growing up online. You can read our full parent guide, ‘WhatsApp & your child’, on our resources page.

There’s no web browser on the Sayph phone, and keeping children off the open internet is a core part of what makes it safer. If we ever do offer a browser, we’ll only do it once we’re confident it can be done safely – that’s our priority, not the timing. And it would never simply appear on your child’s phone: a browser would never be added by default, or slipped on through a software update without you knowing. A parent would always have to actively choose to add it, and you could leave it off entirely.

No, and that’s deliberate. There’s no app store, and apps can’t be downloaded or added on; the phone stays limited to communication and a few necessary extras (like maps and radio) that support children and young people in exploring and enjoying the real world. We believe that’s the most secure approach.

It’s also a deliberate guard against the slippery slope. If a phone can always have ‘just one more app’, it can quietly drift towards social media and end up only delaying the inevitable by a few months, rather than holding the line for several years. Because extra apps simply aren’t available, you can’t be nagged into installing something you don’t want, which we hope takes the heat out of those repeated requests for more. Plenty of phones treat child safety as a tick-box; we want to go further than that.

If you’re still comparing your options, our complete guide to phones for kids weighs up every route, and our best first phone for kids buying guide runs through them one by one.

We believe that safer phones should be available to all children, so have worked hard to keep the costs low. The 4G Sayph Phone is available to buy now for £189. Monthly subscription from £4.99/month. You will just then need a SIM & call plan (available from £2–3/month).

Parents can select which contacts are approved for exchanging MMS (picture messages) with. This is to reduce the risk of children and young people either being sent images they don't want to see, or pressured into sending something they shouldn't. New contacts default to ‘No MMS sharing’ so photos will only be exchanged with people you’ve expressly approved for them.

The Sayph phone works with any standard UK SIM card. You buy the SIM yourself from any provider – Sayph does not sell SIMs. You can use a SIM you already have or pick up a low-cost plan from providers like Smarty, Giffgaff, or Tesco Mobile. The Sayph phone uses a nano-SIM and supports all major UK networks (EE, Three, O2, Vodafone and their MVNOs).

If you live somewhere with patchy mobile reception, it’s worth checking with the provider that your chosen plan supports Wi-Fi Calling (sometimes called VoWiFi) before you commit. This lets the phone make calls and send texts over WiFi when the mobile signal is weak. Most major UK networks support it, but not every low-cost plan does, so it’s worth confirming first.

You can compare low-cost SIM-only plans on independent sites such as MoneySavingExpert, Uswitch and MoneySupermarket. If you think your child may want to send picture messages now or in the future, it’s worth choosing a plan that includes MMS, as not all plans do and it can be costly to add later on some networks. Smarty SIM-only plans, for example, include MMS as standard – though we mention this for information only and it is not a recommendation of any particular provider.

Calls and texts work on any SIM, but live location tracking, remote monitoring and online maps need a mobile data connection to work when your child is away from WiFi. You don’t need a large allowance – only a little data is required – but we’d suggest choosing a plan that includes some, so these features keep working when your child is out and about rather than only updating once the phone reconnects to WiFi.

No, and we’d be suspicious of any product that claimed to. Sayph gives you visibility and control, but it doesn’t monitor your child’s wellbeing in real time and it isn’t an emergency service. It works best alongside the conversations you’re already having. We also encourage you to be open with your child about what the phone shares with you; in our experience, that openness is what builds trust rather than resentment. If you’re ever worried about a child’s immediate safety, call 999.

As little as possible, for as short a time as possible. Messages, call logs and location history are encrypted, visible only to you (never to Sayph staff), and automatically deleted after a maximum of 30 days. We don’t sell data, we don’t profile children, and our AI summary provider is contractually barred from training on your family’s data. Full details in our Privacy Policy.
