No apps. No browser. No algorithm.
There is no app store. There is no web browser. There is no way to install Instagram, TikTok or Snapchat. The phone cannot be used to scroll. That is the point.
no. 01 Knock's first pick
Nokia 3210 (2024)
Short answer. If you need to pick today, the Nokia 3210 (2024). Around £79 on Amazon UK. Calls, texts, Snake, three days of battery. Done.
Knock's first pick for Year 6 and Year 7 UK families. It looks the part in the playground, which matters more than you'd think.
From £75 on Amazon UK

no. 02 What it does
A phone that does the things a phone is supposed to do, and almost nothing else.
02
Three days of battery.
Charge it on Sunday evening. Forget about it until Thursday. The other phone in your house, the one with the apple on the back, lasts roughly until lunch.
03
Most UK SIMs slot in and work.
Any 4G SIM from EE, O2, Three or Vodafone works. Knock's first pick for a child is ParentShield (£9/month, EE network, whitelist features). The cheapest sensible no-frills option is Smarty at £6/month. Both are on the SIMs page.
04
The conversation, free, in full.
We have written the parent script, the school comms template and the friend-network briefing. Every line of it is on the site, free, with no email gate. A printable version of the same three pages is one click away if you would rather have it on paper.
no. 03 The conversation
The phone is the easy part. The conversation is the hard 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 it. So we wrote one, from the public framing of UK parent campaigns who had already had it. It is one page. It is on the site, for free, with no email gate. The full seven-moment version, the school comms paragraph and the friend-network briefing are all there too.
no. 04 The case for waiting
The case for waiting, condensed.
The mental-health correlation between smartphone use and adolescent wellbeing is now strong enough that the Department for Education has issued school-day guidance, the largest UK parent surveys are running in clear majorities for delay, and a movement of half a million UK parents has organised under Smartphone Free Childhood since the start of 2024.
We will not pretend the science is settled. Most of it is correlational, and Jonathan Haidt's case in The Anxious Generation rests on patterns rather than experiments. What we can say is that hundreds of thousands of UK families have already decided the case is strong enough to act on. The Nokia 3210 is the practical step on the other side of that decision.
no. 05 Before you buy one
Before they go and buy one.
Which SIM should I use with it?
Any UK 4G SIM works. For a child, we recommend ParentShield (£9/month, EE network, whitelist features). The cheapest sensible no-frills option is Smarty at £6/month. Both are on the SIMs page. The SIM slot is a regular nano-SIM with a microSD slot beside it.
Is this a gift-friendly phone?
Yes. Amazon ships to a different address with gift options. A nice low-key thing to slide into a wrapped book.
What happens if it breaks in the first year?
The 3210 carries the standard Nokia 24-month manufacturer warranty. The UK retailer you bought it from handles returns and replacements under UK consumer law. Amazon UK is straightforward for both.
Can my child still listen to music?
Yes. The phone has an FM radio and an MP3 player. There is a microSD slot for music files and a 3.5mm headphone jack. Any cheap wired earphones work.
Will the school object?
In the named UK press coverage of these campaigns and the DfE policy text, no. The Department for Education guidance from February 2024 prohibits smartphone use across the school day. A basic phone in a school bag, switched off, is not the issue the guidance is trying to address. The school-side toolkit at /teachers-and-carers is designed to make this conversation with the head of year a short one.
Quietly off the smartphone, together.
From £75 on Amazon UK. The conversation guide is free on the site. If the 3210 is not the right fit, we have six other phones we'd buy.
