What you pay, month by month
The code takes 75% off the first payment. On Freedom One, Chattr's unlimited 5G data, calls and texts plan, that is £3.75 instead of £15. From the second month you pay £15, then a £14 loyalty price, then £13 from month 12. Chattr's homepage starts the £14 price at month 6; its Parents Hub says month 7.
Add up the first twelve payments and Freedom One comes to about £161. Unlimited data at Lebara (£22.50 on a 12-month plan), Lyca Mobile (£25 after a half-price first 30 days), 1pMobile (£25) and VOXI (£35) costs £270 to £420 over the same twelve payments. Lyca's 24-month Unlimited contract is closest at £162 in year one, then £216 in year two against Chattr's £156.
Is the network good enough?
Chattr owns no masts. It sells plans on O2 and Vodafone, and a Chattr SIM may carry either name. Chattr quotes 99% 4G and 5G coverage across the UK. The brand is run by Kashcow Ltd, a Salford company, and sells online only.
The terms that protect you
- No contract. Switch off auto-renew and the plan stops at the end of the month.
- No credit check.
- A £5 bill limit on every account, so extras cannot run up a surprise bill.
- A 14-day refund window from activation, less the days used.
- Roaming in 43 European destinations on your UK allowance, fair use applying.
Who it suits
Streamers and people who use their phone as a hotspot, who would outgrow a 50GB plan. Parents buying a child's first SIM, who get unlimited data, a bill cap and no contract. Anyone who dislikes annual price rises, since Freedom One's price moves down, not up.
