Snake
The first game most people over thirty-five played on a phone. Still loaded on the Nokia 3210. Still calming. No algorithm.
You're not behind. You're being careful.
Your kid wants a phone. You want to get it right.
Knock finds the right first phone for your child, and the words for the conversation, in about ninety seconds. Built from the UK research. No scaremongering, no sign-up.
Drawn from Ofcom, the DfE and Smartphone Free Childhood. Free to use, no sign-up.
What "Knock" means
Here's the thing nobody says out loud: that bad feeling about handing a ten-year-old the whole internet is the sensible one. You've just never had a free evening to test whether you're right.
It's not a daft feeling. And you won't be the only family at the school gate acting on it, or the only one for long.
A phone quietly takes the afternoon a child used to fill themselves: going round, knocking on, seeing who was about. That knock is the verb the site is named for. Four things worth keeping hold of.
ii.
Knocking for a friend
The doorstep, the friend's nan, the negotiation in the November rain. A real conversation with a real adult before the rest of the afternoon begins.
iii.
Being silly without being posted
The cartwheel on the field. The wig from the dressing-up box. The bad joke. Three friends laughing, nobody filming, no screenshot the next morning.
iv.
Finding yourself, slowly
A series of small private experiments, clothes, music, opinions, accents, that you try, abandon, try again. None of them performed for an audience of three hundred classmates.
Why three families are easier than one
Most parents already know this in their bones. One family standing alone against the year-six WhatsApp group feels mad. Three families switching in the same fortnight feels reasonable. That is the whole trick.
So the work is in two pieces. The phone you'd choose if you were free to choose. And the conversation, on paper, that you can put in the other two families' hands on the school run, so they can have it at their own kitchen tables the same week. The first day is hard. The week after is easier. The year after, there's no conversation to have.
Two things behind it. Behaviour-change theory, the unfun bit. A stubborn belief that childhood was better with Snake in your pocket and nobody filming, the obvious bit.

The conversation
The bit nobody tells you is that the phone is the easy part.
They thought the hard bit was choosing the phone. The hard bit was the kitchen-table conversation the night before they handed it over. There was no script for that conversation. So we wrote one, from the public position of UK parent campaigns who had already had it.
It is one page. Read it through twice. Pick a Saturday evening when neither of you is tired. Stop talking when they have heard you out. Twenty minutes is enough.
Bring snacks for after. Day one will not be quiet. The face your child pulls is the face of a child who has just watched their 99 hit the gravel in front of the seagulls. By day six it is Tuesday again. By week three they will have lost the phone once, which is, as it happens, exactly why a £75 Nokia is the right answer.
A page from the script (free on the site)
"We've been thinking about phones, and we want to tell you what we've decided. [pause] We are not going to get you a smartphone yet. We are going to get you a phone with the things you actually need. Calls. Texts. A torch. Music if you want it.
What it isn't going to have is Instagram, TikTok, Snapchat, or a browser. Not because we don't trust you. Because the apps are designed to keep you on them, and we don't want that for you yet."
Then stop talking. Wait for them to react. Don't fill the silence.
The conversation, moment 03 of seven
Knock's first pick
The Nokia 3210 (2024).
A phone that does the things a phone is supposed to do, and almost nothing else.
The Nokia 3210 (2024) is Knock's first pick as a first phone. Calls, texts, a torch for the walk home in winter. An FM radio and an MP3 player for the bus. Three days of battery.
What it does not have is a web browser, an app store, or a way of installing Instagram or TikTok. The phone cannot be used to scroll. That is the point.

What it is not
The Nokia 3210 is not
the cheap version of an iPhone.
It is the considered version of a phone.
The starting question was not "what if a smartphone had fewer features." It was "what if a phone did the things a phone is supposed to do, and almost nothing else." The 3210 was the answer to that question in 1999. The 2024 reissue is the answer to it now.

Questions parents ask, before they pick a phone
Six questions parents ask before they pick a phone.
Short answers below. The longer ones, with the trade-offs and the named retailers, live across /best-simple-phones, /pricing, /switching-kit and /teachers-and-carers.
What is the best simple phone for a UK child?
The Nokia 3210 (2024), around £79 on Amazon UK. 4G, network-certified, three days of battery, original Snake. Knock's first pick as a first phone for ages 10 to 13. The ranked list, with the runners-up and the trade-offs, is at /best-simple-phones.
How much does a simple phone for a child cost in the UK?
Between £24 and £400, depending on what you want it to do. The Nokia 105 4G, the cheapest 4G basic we recommend, is around £24. A 4G basic phone like the Nokia 3210 sits at around £79. The Pinwheel Plus, a smartphone-shaped device with a parent-controlled launcher, is £279 plus a monthly portal fee. The Light Phone III, imported from the US, is £399. Full pricing ladder at /pricing.
What if my child's school requires a smartphone-shaped device?
Some UK schools insist on a smartphone for specific apps. In that case, our recommendation is either the Pinwheel Plus (£279 plus £13.99/month, parent-controlled launcher, whitelist not blocklist) or a refurbished iPhone SE (£169 at Back Market UK) with Apple Screen Time set up properly. The picker at /which-phone walks you through the choice in ninety seconds.
What about my child being left out of WhatsApp groups?
There is a real social cost in the first fortnight and almost none after that, in the named UK press coverage of these campaigns. The strongest single predictor of a smooth first fortnight is whether one or two other families in the friend group step out in the same window. The friend-network briefing on /switching-kit is one paragraph designed to make that conversation with other parents simple.
Does Knock sell phones?
No. Knock is a UK content and affiliate site. We recommend phones available from UK retailers, and earn a small affiliate commission only on the Amazon UK buy buttons through Amazon Associates. Every other retailer link on the site is direct, no commission. The conversation script, school comms templates and friend-network briefing are free on the site with no email gate. Full affiliate disclosure at /affiliate-disclosure.
How do I actually have the conversation with my child?
The script we publish is built from the public framing of UK parent campaigns like Smartphone Free Childhood and Wait Until 8th, refined into the shape that holds together in twenty minutes when you've read it twice. The seven moments, the eighteen common objections, and the full printable kit live at /switching-kit. The school side, for headteachers and family carers, lives at /teachers-and-carers.
Phones, kept simple. Childhood, kept longer.
