The phone we recommend most
A first phone that gives your child back their childhood. The phone we hand to year-six and year-seven families most often.

Where to buy
Some links earn us a small commission at no cost to you. How we choose →
We're building a Knock-curated kit (the phone, a UK SIM, the printed conversation, the box) for parents who'd rather have one box arrive on a Tuesday than assemble it themselves. We're taking pre-orders by email. Join the kit waiting list →
What's in the box
The kit is built for the moment you open it together with your child. The phone is charged. The SIM works. The script is on top.
What it is
01
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 entire point.
02
The SIM is pre-activated to your address. 200 minutes, 200 texts, 1GB of data a month, on EE. No contract. Top up later if you need to. You can port a number across in the first week if you like.
03
Charge it on Sunday evening. Forget about it until Thursday. The week we tested it with a year-7 in Leeds, it lasted four and a half days on a single charge, and she was texting her best friend every fifteen minutes. The other phone in your house, the one with the apple on the back, lasts roughly until lunch.
04
Inside the box is a one-page parent script, a one-paragraph school comms template and a one-paragraph WhatsApp briefing for the other parents. Read the script twice before you sit down. The whole conversation takes twenty minutes.
The science, in two paragraphs
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 Knock Phone is the practical step on the other side of that decision.
From families who switched
“We had been putting it off the way you put off rewiring the kitchen. The phone arrived on the Thursday. We did the conversation that night. By the second week of half-term she had stopped asking about her friends' Instagram and started doing handstands in the garden again.”
“I had not realised the conversation was half pauses until I read the script through. She cried, I did not fill the silence, she came back to it twenty seconds later. We were done in twenty-two minutes. Three months later, we have not had the conversation again.”

Questions about the kit
The SIM is already in the phone when it arrives. It is registered to your shipping address, and the first month is included in the kit price. From the second month, you top up directly with EE if you want to. You can port a number across in the first week.
Yes, often. At checkout you can ship to a different address and include a small gift note. The SIM activates to whatever address you send it to.
Send it back and we replace it. The phone itself carries the standard Nokia 24-month manufacturer warranty. Our family guarantee covers the box, the lanyard, the cable and anything else that should not fall apart in normal use.
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. The wired earphones in the kit work for both.
In our experience, no. We have heard back from over forty UK schools and none have asked us to take the phone out of a child's bag. The Department for Education guidance from February 2024 prohibits smartphones across the school day. A basic phone in a school bag is not the issue the guidance is trying to address.
£79, next working day, conversation included. If it does not work for your family, send it back inside 30 days.
