Chattr SIM Only Deals

Which network does Chattr run on?

Chattr is an MVNO, a virtual operator that sells its own plans on another network's infrastructure. Chattr's deals run on the O2 network, so the 4G and 5G signal you receive is the same as an O2 customer would get in the same spot. If O2 performs well where you live and work, Chattr will too. For a fuller comparison of the providers sharing that infrastructure, see our guide to which networks use O2.

Do I need a credit check on a Chattr SIM only contract?

No. Every Chattr deal we list is a no credit check plan, and you pay month to month rather than committing to a long contract. That makes Chattr a practical option for students, people new to the UK, or anyone whose credit history makes the bigger networks awkward to join. To compare against other providers that skip the search, see our no credit check SIM only deals.

Which Chattr deal is worth your money right now?

Chattr at £15.00 a month for 50GB is the pick. It is the strongest value in the range, with unlimited minutes and texts, 5G and eSIM support included, and no credit check to pass. If you use less data, the 25GB plan at £14.00 a month is only a pound cheaper, so the 50GB plan is the better buy unless your budget is fixed. The £20.00 unlimited data plan is fairly priced but not the cheapest route to unlimited, so compare it against our unlimited data SIM only deals before committing. Chattr also rewards loyalty, with advertised pricing that steps down the longer you stay, and it does not apply price rises, which is worth factoring in against networks that apply an annual mid-contract increase.

Can I get an eSIM on a Chattr SIM only contract?

Yes. Every Chattr deal we list is available as either a standard SIM or an eSIM, so you can activate digitally without waiting for a card in the post. Use the eSIM filter above to show digital SIM deals, or browse eSIM only deals across all networks. If you are not sure whether your phone supports them, our eSIM guide covers compatible handsets.

Does 5G come as standard on Chattr SIM only deals?

Yes. Every Chattr plan we list includes 5G at no extra cost. Whether you actually get 5G speeds depends on your handset and your location, so check coverage for your postcode before you buy.

Does Chattr include EU roaming?

Yes. Roaming is included on Chattr plans at no extra cost in 43 European destinations, with your UK allowance used abroad. Chattr does not publish a detailed roaming fair use policy on its website, so if you are planning a longer trip it is worth confirming your roaming allowance with Chattr before you travel.

1 month vs 12 month: which is right for you?

Chattr only sells rolling 1 month plans, and that is the honest trade-off to weigh. You can leave or change plan any month without penalty, but you will not get the lower pricing that sometimes comes with a longer commitment. If you would rather trade flexibility for a lower monthly cost, compare 12 month SIM only deals. If rolling flexibility is exactly what you want, you can weigh Chattr against the wider market on our 30 day SIM only deals page.

How we rank Chattr SIM only deals

By default, deals are sorted by lowest monthly price. You can change the sort order at any time using the controls above the listings and filter by data allowance, contract length, minutes, and eSIM availability. All deals shown are updated automatically. SIM Only Finder is an Ofcom-accredited UK mobile comparison site and earns a commission on deals taken out via our links. This does not affect how deals are ranked.
