Is Chattr worth it in 2026?
Yes, for anyone who wants unlimited data at one of the lowest standard prices in the UK without signing a contract. Chattr's Freedom One costs £15 and falls to £13 the longer you stay, and new customers halve the first month with code NewSept50 until 30 September 2026, entered at checkout after ordering through the link on the HonestCodes Chattr page (honestcodes.co.uk/codes/chattr).
Key takeaways
- Promo code NewSept50: 50% off your first month for new customers until 30 September 2026 — Freedom One £7.50 instead of £15.
- Freedom One's price only moves down: £15, then a £14 loyalty price, then £13 from month 12.
- Data plans: 6GB £10, 25GB £11, 50GB £12, all with unlimited UK calls and texts.
- No contract and no credit check; switch off auto-renew and the plan ends at the close of the month.
- Roaming like at home in 43 European destinations, including Switzerland, Jersey, Guernsey and the Isle of Man.

A plan that gets cheaper
Chattr's pitch is the opposite of the annual price rise. Its unlimited Freedom One plan starts at £15 a month, drops to £14 as a loyalty reward and reaches £13 from month 12, with unlimited 5G data, unlimited UK calls and texts and European roaming throughout.
Chattr's homepage starts the £14 price at month 6 and its Parents Hub at month 7; both put the £13 price at month 12. On either schedule, a customer who stays pays less each year.
What NewSept50 is worth
NewSept50 is Chattr's September offer for new customers: 50% off the first month on any plan, until 30 September 2026. Freedom One's first month becomes £7.50; the 6GB, 25GB and 50GB plans become £5, £5.50 and £6.
Chattr's discount-code policy limits codes to the first month unless stated otherwise, and one code per order. The code goes in at checkout, on the step after you create your account.
Who runs it, and on which network
Chattr is a trading name of Kashcow Ltd of Salford, an online-only operator that sells on the O2 and Vodafone networks — a Chattr SIM can carry either name. O2-network customers get O2 Priority, and Chattr quotes 99% 4G and 5G UK coverage.
It is a young brand, and it says so, leaning on human customer care and simple terms rather than a long track record.
Built for parents
Chattr's Parents Hub makes the case that unlimited data is the safest plan for a child: its own estimates put TikTok at around 1GB an hour and streaming at around 3GB an hour, so a capped plan runs out fast. Every account also carries a £5 bill limit by default.
With no contract and a 14-day cancellation refund, trying Chattr for a child's first phone carries little risk. The account holder must be 18 or over.
The verdict, and why this code
Chattr is worth it for anyone who wants unlimited data cheaply and flexibly, and it gets better value the longer you keep it. The half-price first month makes the switch almost free.
The code, plan prices and rules here come from Chattr's own published offer, pages and terms, read on 23 September 2026. HonestCodes tests the link daily and replaces the code the moment Chattr's next offer goes live.
