Bag a crazy cheap UK unlimited data SIM this Black Friday weekend

Vodafone, Three and O2 have some serious discounts on unlimited data SIM-only plans.

In addition to some pretty great deals on Android phones this Black Friday weekend, the UK networks have also reduced their unlimited 5G SIM-only plans to some of the cheapest prices we've ever seen.

Vodafone, Three and O2 have all reduced prices for their unlimited SIM-only plans to around the £20-25 level, with unique perks for each.

Vodafone's SIM-only deals are available until November 29, and the operator's 5G Max plans come with 5G connectivity at the network's fastest possible speeds.

Vodafone Unlimited Max

From £20 per month at Vodafone

Vodafone's cheapest plan with unlimited calls, texts and data is a 24-month deal for £20 per month, and also includes roaming in the EU for £1 per day from 6 January 2022. (Before then it's free.) Add an entertainment bundle for an extra £7 per month.

Three has the cheapest unlimited data deal we've seen for Black Friday. It'll also cost you £20 per month for most of the two-year lifespan of the contract, but Three will give you 50% off for the first six month, so you're up £60 in the long run.

Three Advanced Plan

£10 for the first 6 months at Three

Three's unlimited Advanced Plan also boasts unlimited calls, texts and data, and is half price for the first half-year of the contract. Hotspot is included, and European roaming will cost you £2 per day.

O2's unlimited deal is a little pricier than the others, but still well worth a look. The carrier's Black Friday deals are live all the way through until December 8.

O2 Unlimited Data Plan

£25 per month at O2

O2's unlimited data deal costs £25 per month, and includes six months of free Apple Music, and a choice of six months of Disney+ for free, or 12 months of another benefit. If you're also a Virgin Media customer, you'll unlock more benefits when you sign up for this plan.

Finally, EE isn't discounting its unlimited data plan for Black Friday -- it's still £35 per month. But the UK's biggest operator is offering a 160GB plan -- which should be effectively unlimited for most people's uses -- for £20 per month. Alternatively you can pay £25 for the same 160GB of data plus a choice of one of EE's Smart Benefits, which include Apple TV, Apple Music, BT Sport Ultimate or international roaming.
