1pMobile sells a 30-day rolling unlimited data plan on SIM Only, so there’s plenty of flexibility and no long contracts.
This plan – which is competitively priced – also comes with unlimited minutes and texts, 5G with no speed caps, Wi-Fi Calling, 4G Calling, tethering, and inclusive EU roaming.
1pMobile’s unlimited data plan gives you the freedom to cancel your plan or change your allowances almost whenever you want, as it’s a 30-day rolling plan.
Plus, the network offers family bundles, where any additional unlimited data SIMs that are added to your account are charged at half price, so there are big savings to be had if you want multiple plans.
There also aren’t any credit checks on 1pMobile, and you can expect high speeds, because the network shares EE’s coverage, and EE for its part was found to have the highest median 5G download speed in a 2025 RootMetrics report, coming in at 241.2Mbps. It also took the crown for ‘best 5G experience’ and ‘best overall performance’. So 1pMobile is likely to be similarly good.
1pMobile limits you to 500GB per month on its unlimited data plans, but that’s far more than you’re ever likely to need if using this for personal use in a phone. Should you exceed this, your speeds may be throttled. However, there are no speed caps when using less than 500GB.
There’s also a 14GB data limit when roaming abroad.
Yes, 1pMobile allows tethering with unlimited data, so you can use your connection to get other devices online, and the only restriction is that 500GB fair use limited detailed above.
1pMobile’s plans include free roaming in 46 European destinations, but this is subject to a14GB fair usage limit, so you can’t use an unlimited amount of data abroad.
However, the vast majority of networks have roaming limits, so this isn’t an unusual restriction.
Yes, 1pMobile offers an unlimited data bundle on Pay As You Go, but this is a one-year pre-pay bundle, meaning at the time of writing you’d have to pay £270 for it upfront, but would then get unlimited data (as well as unlimited calls and texts) for a full year.
Given that one of the main benefits of Pay As You Go is usually its flexibility, this might not appeal to many – but if you want a shorter-term plan then the 30-day unlimited data SIM Only option detailed above is a good bet.
Yes, as well as 1pMobile you can also get unlimited data on Three, EE, O2, Vodafone, Asda Mobile, Giffgaff, iD Mobile, Lebara, Lyca Mobile, Sky Mobile, Smarty, Tesco Mobile, Talkmobile, and VOXI.
