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 it costs
Freedom One is £15 a month for unlimited 5G data, calls and texts.
Enter HONEST75 at checkout and the first month drops by 75%: £3.75 for Freedom One. Your next payment, at the full price, falls one month plus three days after you order.
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
Chattr is worth it for anyone who wants unlimited data cheaply and flexibly, and it gets better value the longer you keep it.
The plan prices and rules here come from Chattr's own pages and terms, read on 23 September 2026. HonestCodes tests the link daily and re-checks the prices monthly.
