Big data, little prices. Sky Mobile has you covered.

Looking for a new mobile plan without spending a small fortune? Sky Mobile has rolled out a selection of tempting SIM-only offers, with prices starting from just £6 a month.

Whether you’re after a little data to get you through the day or enough to scroll, stream and share to your heart’s content, there’s something to suit different needs and budgets.

Better still, you can choose between longer 24-month contracts and flexible 30-day plans, with unlimited calls and texts included across the board.

Sky Mobile’s latest 24-month SIM-only deals

If you’re happy to commit to a longer contract, Sky Mobile has three particularly attractive offers worth considering. Each of the following plans come with unlimited UK calls and texts.

Data allowanceMonthly priceDeal
10GB£6See Deal
50GB£11See Deal
Unlimited£20See Deal

At just £6 a month, the 10GB plan is a great starting point for those who mainly use their phones for messaging, browsing and the occasional bit of streaming.

For an extra £5, the 50GB plan offers considerably more breathing room, making it an appealing option for heavier data users.

And if watching videos, gaming or scrolling through social media regularly keeps your data allowance on its toes, the £20 unlimited option means you won’t have to keep checking how many gigabytes you’ve got left.

Prefer more freedom? Check out Sky’s 30-day contracts

Not everyone fancies being tied down for two years, and that’s where Sky Mobile’s 30-day contract SIM-only plans come into play.

These shorter contracts offer greater flexibility if you’re unsure about making a longer commitment or simply want to keep your options open.

Data allowanceMonthly price
5GB£11
25GB£15
75GB£19

Each plan comes with unlimited UK calls and texts, with options ranging from an everyday 5GB allowance to a generous 75GB for those who regularly use mobile data.

These promotional 30-day offers are scheduled to remain available until 10 December 2026 at 11:59pm.

To find them, visit Sky Mobile’s plans page and switch the contract duration from 24 months to 30 days.

What else do you get with Sky Mobile?

It’s not just the prices that make these offers worth a look. Sky Mobile includes a few handy features that could make your monthly plan go further.

  • Roll over unused data: Any spare data from eligible plans goes into your Sky Piggybank, where it can be saved for up to 12 months rather than disappearing at the end of the month.
  • Change your data plan: Need more or less data? Sky Mobile lets you switch your allowance during your contract, although changing plans may affect promotional pricing.
  • Unlimited calls and texts: All the featured plans include unlimited standard UK calls and texts.
  • UK-wide coverage: Sky Mobile advertises 99% UK population coverage on its 4G network.

Data rollover isn’t available with Unlimited plans, and prices may increase during your minimum contract term.

Looking for a new phone too?

If your trusty old handset has seen better days, Sky Mobile also offers a wide selection of phones to pair with its SIM plans.

From the latest Apple iPhones to Samsung Galaxy and Google Pixel devices, there are plenty of options for those looking to upgrade.

Is it time to make the switch?

Whether you’re trying to bring down your monthly bills or simply want a bigger data allowance, these Sky Mobile offers provide plenty of food for thought.

The £6 10GB deal stands out for budget-conscious customers, while the £11 50GB option could hit the sweet spot for anyone wanting more data without a hefty monthly bill.

And if you’d rather avoid a lengthy commitment, the 30-day alternatives offer another way to stay connected.
