SIM-only deal: Get six months half price from Three

Three has slashed the price of its SIM-only contracts by 50% for the first six months

Three routinely drop discounts to leave its rivals in the dust, but this one is a real doozy: a simply stunning 50% off the price of an SIM-only 5G data for the first six months of a 24-month plan.

That means you’ll be paying just £12/mth for all the data you could possibly desire and make an overall saving of £72 before the price rises to £24/mth for the rest of the plan. By comparison, O2 offers the same package for £30/mth, while for Vodafone it’s £32/mth and EE it’s £28/mth. Plus, Three’s 5G is the best in the business for UK customers. 

There are also half price savings to be had on many of Three’s other SIM-only contracts, so read below for more details on the Three network itself and how you can take advantage before this deal disappears.

In our latest review of the Three network, we found it to offer solid all-round reliability, including elite and ever-improving 5G performance. It’s not just us either, Opensignal awarded Three the 5G Download Speeds gong in September for its rapid 228.4Mbits/sec delivery. That’s well ahead of the 130.5Mbits/sec speeds achieved by second-placed EE and a 24Mbit improvement on Three’s speeds in April this year. It was also the outright winner for 5G reach with a score of 3.3, meaning Three users found a 5G connection in over a third of locations in the UK, and with the strongest connection availability of 3G and above across British shores.

The awards don’t stop there either: Three was also Opensignal’s joint winner for 5G availability and 5G Video Experience (essentially, it’s users had the joint best experience when streaming over a 5G connection), which really emphasises that this is one of the best 5G-ready SIMs you can get at present. The only slight negative we found was Three’s fairly average customer support scores and around 2/10 feeling a little disappointed with their service in our Mobile Network Awards survey.

As this unlimited data deal shows, Three offers pretty stellar value for money too with this our pick of the deals currently on offer with the mobile network. But should you prefer limiting your gigabytes to something more manageable – and crucially, for a little less money per month – then Three also has 250GB available for £10/mth for the first six months (£20/mth thereafter), as well as 100GB of data for £8/mth (£16/mth after six months) and 30GB for £7/mth (£14/mth after that). Again all of these SIM-only contracts have unlimited texts and minutes and you’ll want to act fast to avoid disappointment.

Should Three just not be for you though, or you want to check out its competition in the SIM-only stakes, have a gander at our best SIM-only deals page for more offers.
