Sky Mobile UK

New customers looking to join mobile operator Sky Mobile (Sky Broadband), which is a virtual provider (mvno) on O2’s national 4G and 5G network, may like to know that they’ve launched a bunch of new discounts on their SIM Only plans. For example, you can now get 1GB of data, including unlimited calls and texts, for just £1 per month (down from £3).

In addition, Sky Mobile’s 10GB data plan has been reduced to £10 per month (down from £14), while 60GB is now £14 per month (down from £22) and their top “unlimited data plan” is just £19 per month (down markedly from £29). All of these offers are on 12-month terms, with prices returning to normal thereafter. As usual, you’ll need to click the Sky affiliate links in this article to get these discounts.

NOTE: The new offers, which are some of the cheapest ones for mobile that we’ve seen from Sky, will be available to take until September 18th, 2025.

Sky’s mobile plans also support data rollover (unused data goes into a piggybank for future use), as well as the flexibility to change your mobile plan up or down whenever you like, zero-rated data usage (free) when streaming on Sky’s TV apps and the ability to swap to a new phone, tablet or laptop whenever you want, albeit with some limitations.
