Stream Netflix to your heart’s content with Three’s £10 unlimited data SIM

If you’re a serious binger on the go, look no further than Three’s unbelievable unlimited data SIM, going for just £10 a month for the first six months of your contract.

Once the six months are up, it’ll be bumped to £20 a month, but that still makes it the most affordable unlimited SIM on the market right now. By comparison, Virgin Mobile’s unlimited SIM costs £32 a month and is only available to existing TV and broadband customers, while Vodafone’s £26 a month plan is a little more affordable, but not more so than Three’s offering.

No matter how you swing it, Three has got the competition beat right now on price, so if you’re the type of person who needs a serious wad of data with them at all times, then this deal should be a no brainer.

So what else do you get outside of an absurd amount of data that no normal person could ever tangibly consume? Well, I’m glad you asked. One of Three’s most endearing features is its Go Roam service, which allows you to use your tariff abroad in 71 countries, without incurring any extra charges. For anyone suffering from wanderlust, it’s a dream come true.

As an added bonus, the SIM in question is also 5G-ready as Three begins to roll out its 5G schematics across the UK. Once the system’s up and running, you’ll be able to download movies and television shows in a matter of seconds, not minutes.

For you business types out there, you’ll also be happy to know that you can use your Three data as a hotspot, letting you tether other devices like your laptop to your phone – a particularly handy bit of tech for when you just can’t get the Starbucks Wi-Fi to connect.
