Which networks offer unlimited data on Pay As You Go?
EE, Three, Vodafone, Asda Mobile, iD Mobile, and Lyca Mobile all offer Pay As You Go bundles with unlimited data. These are true Pay As You Go plans with no credit check, but after that we've also decided to take a look at the networks that offer similar bundles on 30-day rolling plans that aren’t strictly classed as Pay As You Go.
EE
 |
Unlimited data Unlimited mins Unlimited texts * Max speeds 25Mbps |
£35 a month |
EE didn’t used to offer unlimited data on Pay As You Go, but it now does. However, with a price of £35 per month it’s not cheap, and speeds are capped at 25Mbps, which isn’t particularly fast either. Roaming also costs extra.
Still, EE’s coverage is widespread, so you can at least be confident you’ll get a signal in most places.
Three

Three offers a range of packs on Pay As You Go, with one coming with unlimited data. This costs £31.00 at the time of writing, and also includes unlimited minutes and texts.
Like most Pay As You Go packs it lasts 30 days and doesn’t tie you into a contract. It also comes with 5G data, and perks such as inclusive roaming in over 70 destinations, and access to the Three+ app, which is packed full of offers and discounts from other brands.
Vodafone

Lasts for 30 days Unlimited data Unlimited mins Unlimited texts |
£40 a month |
Vodafone’s unlimited data Pay As You Go bundle costs £40, lasts 30 days, and also includes unlimited minutes and texts.
It’s 5G-ready and while it doesn’t include roaming, you can purchase a Europe Extra or Around the World Extra add-on for a low cost to enable roaming. There’s no contract, and you also get access to Vodafone’s VeryMe Rewards app, which has treats, giveaways, and prize draws.
Asda Mobile

£24 a month |
Asda Mobile offers a 30-day SIM plan with unlimited data which it advertises as being Pay As You Go.
This also comes with unlimited minutes and texts, it includes 5G, and it’s competitively priced. You can also roam at no extra cost in 46 European destinations (up to a 5GB fair usage limit), and Asda Mobile uses Vodafone’s infrastructure in the UK, so its coverage and speeds are both respectable.
iD Mobile

iD Mobile’s unlimited data Pay As You Go bundle is a bargain at just £20 for a 30-day duration. As with other networks you also get unlimited minutes and texts here, and you can roam across the EU and beyond at no extra cost (up to a 30GB fair usage limit).

Networks offering unlimited data on 30-day bundles that automatically renew
O2, 1pMobile, Giffgaff, Honest Mobile, Lebara, Smarty, Spusu, Talkmobile, and VOXI all also offer unlimited data bundles with no contract.
These networks don’t advertise their unlimited data bundles as being Pay As You Go, instead listing them as SIM-only, but as these plans only last 30 days, don’t tie you in, and in many cases don’t require a credit check, they’re very similar and are worth considering. At the time of writing the only ones that do require a credit check are O2 and EE.
The only thing to watch out for is that they will typically automatically renew each month, whereas true Pay As You Go bundles won’t unless you opt into them doing.
O2
