Sky Mobile 5G+ First To Standalone

Sky is a name most of us associate with a dish on the roof and a red streaming box under the telly, not cutting-edge mobile tech. So here's a nice bit of trivia for your next pub quiz, Sky Mobile has just quietly become the first MVNO on O2's network to switch on 5G+, also known as 5G Standalone, beating every other reseller riding on O2's infrastructure to the punch. For a company best known for satellite dishes, that's a proper milestone.

What's Actually New

5G+ is the industry's shorthand for 5G Standalone, a version of 5G that runs on an all-5G core network instead of leaning on 4G infrastructure behind the scenes the way most “regular” 5G still does. We've covered exactly what that means and why it's faster and more reliable in our full explainer, What Is 5G+?, but the short version is this, it's the same 5G you already know, built on newer foundations that make it noticeably better in the moments that matter, busy stadiums, packed commuter platforms, big video uploads. Because Sky Mobile runs on O2's network, this upgrade rides on O2's own 5G+ rollout, which had reached 85% of the UK population by April 2026 and keeps growing, most recently pushing into Kent.

Why This Is a Bigger Deal Than It Sounds

MVNO customers usually wait. New network technology tends to land on the parent network first, EE, O2, Vodafone, Three, and trickles down to the resellers running on top of them later, if at all. Sky Mobile jumping the queue and landing 5G+ ahead of every other MVNO on O2's network flips that pattern, and it's a good sign for what Sky's mobile arm is prioritising as it competes for attention against its own TV and broadband business.

What 5G+ Actually Gets You

In practical terms, faster upload speeds, lower latency for things like video calls and gaming, steadier performance in crowded places where regular 5G tends to struggle, and native Voice over 5G so calls no longer need to drop back to 4G. None of it requires you to do anything differently day to day, it's the network working better underneath a phone you're already using. For the full rundown of what changes and what you need to actually get it, our plain-English 5G+ guide covers device and plan requirements in more depth.

Part of a Bigger Standalone 5G Moment

Sky's move lands as Standalone 5G is quietly becoming the interesting part of the UK's network story generally. O2 keeps widening its own 5G+ footprint, including its recent expansion across parts of Kent, and EE has already started building new features on top of its own Standalone network, like Fast Lane, a priority-connectivity feature for busy places. Sky landing 5G+ first among O2's MVNOs suggests the reseller side of the market is starting to keep pace with that momentum too, rather than trailing years behind it.

Getting It On Your Phone

Worth being upfront about where things stand today, this is very much a first wave. Right now, 5G+ on Sky Mobile only works on three phones,

1. Samsung Galaxy Z Flip8
2. Samsung Galaxy Z Fold8
3. Samsung Galaxy Z Fold8 Ultra

All three are Samsung's newest foldables, so this is squarely a flagship-first rollout rather than something every Sky Mobile customer can switch on today. You'll also need to be using an eSIM rather than a physical SIM. Assuming both of those boxes are ticked, here's what gets you connected,

1. Have one of the eligible phones above
2. Be using an eSIM
3. Install the latest software update
4. Have the free 5G Network add-on active on your account

Do all four and your phone should pick up 5G+ automatically, no further setup needed. To check the add-on is switched on, open the My Sky app, go to Mobile, select Your SIM, choose your data plan, then head to Plan and data settings, where the 5G Network add-on will show as active if you have it.

On coverage, 5G+ is available in most places you'd already get Sky Mobile's regular 5G, though it can vary by exact location and device, which tracks with O2's own Standalone network reaching 85% of the UK population by April 2026 and still growing. One quirk worth knowing, your phone won't always show a distinct 5G+ symbol when you're connected. Some handsets display one, others just show the regular 5G icon even while running on the Standalone network underneath, so the icon alone isn't a reliable way to tell.

The eligible device list is narrow for now, but that's normal for a first wave of anything, and Samsung's newest foldables are exactly the kind of phones early adopters are already carrying. Expect the list to widen as more handsets pick up support, and check Sky's own 5G+ help page for the latest version of this list before assuming your phone is included.

The Bottom Line

Sky Mobile beating every other O2 MVNO to 5G+ is a good look for a network that doesn't always get talked about in the same breath as the big four.
