Deal alert 🚨: Three just revived its dazzling unlimited 4G data SIM-only offer

Already got the phone? Have we got the SIM-only plan for you

Three Sim-Only Deal Price

No, don't panic – you haven't overslept and woken up on Black Friday 2019! Mobile carrier Three has just decided to revive its stunning unlimited everything SIM-only offer, which stole the show during Black Friday last year.  

The brilliant bundle includes unlimited text messages, unlimited calls, and unlimited 4G data for £20 a month. So, regardless of whether you like to natter away the hours on voice calls, fire-off SMS messages like there's no tomorrow, or stream boxsets on your commute every day – this 24-month SIM-only has you covered.

Better still, you can really take advantage of that limitless 4G potential by tethering your smartphone to a laptop, or Wi-Fi only tablet when you're on-the-move to share your internet connection between devices, too. Three never throttles your download or upload speeds over 4G after you've hit a certain data limit on its unlimited plans, unlike some of its rivals.

Three customers can use Snapchat, Apple Music, Netflix, SoundCloud, Deezer, and more without any of the data used counting towards your monthly allowance. It's a cool feature although, since you get unlimited data on this plan, it’s moot.

What definitely isn't moot is the ability to use this SIM-only plan abroad without paying a penny in 70 countries around the world, including countries that are usually financially ruinous to use 4G data roaming, such as the United States, Australia, Brazil, and Hong Kong, as well as the usual cheap EU suspects, including Spain and France. So, your Instagram followers won't have to wait until you're back in Blighty before they're bombarded with pictures of your lower half reclining on the beach accompanied with one of those irritatingly nonchalant captions like "View from my desk looks a bit different this Monday morning ... 🌴"
