Chattr: what to know before you buy
The company
Chattr is an online-only mobile provider based in Salford, Greater Manchester. It describes itself as a newer company and says it wants to offer SIM-only plans at low prices, with a customer care team made up of real people rather than pushy salespeople. Support runs by email and a contact form, so there is no shop to visit and no sales counter to deal with.
The network
Chattr resells O2 SIMs, so your coverage is O2's, while billing and support come from Chattr. The site highlights roaming in European destinations, the chance to keep your number, and what it calls O2 Priority benefits. Chattr says its SIMs are 5G-ready, though you need a 5G phone to use it.
The plans
Plans are SIM-only and run month to month, with no credit check and no long-term contract. The range steps up through fixed data allowances to an unlimited option called Freedom One, which Chattr says gets cheaper the longer you stay. Prices are on the plan pages and in your basket, and they are worth checking before you order.
Getting started
You choose an eSIM or a physical SIM. An eSIM is set up by email instructions and a QR code, while a physical SIM comes by post and is activated with the last digits of its serial number. To bring your number from another network, ask your old provider for a PAC code and enter it during activation.
Saving
Any live code is listed on this page. Copy it and enter it at Chattr's checkout. Because plans are monthly, you can also save by picking the allowance you really use rather than the biggest one, and you can change plan later.
Leaving
Chattr asks you to request a PAC code before you cancel, because it can't issue one after the service has ended. It emails the code to the address on your account and aims to move your number within one working day.
If a physical SIM goes missing in the post, Chattr says its first replacement is free.
