The best value on any main network in the UK today
(5/5, deal rating - full network review here)
None of the other main networks (EE, Vodafone and O2) do value like Three. At the time of writing, this 120GB deal gives you the most data, for the lowest price direct from any major UK network:

Unlimited minutes + Unlimited texts + 120GB data (5G) = £12 a month (12‑month contract)
See full deal
We even wouldn't rule joining on the 24-month version of the same plan at the same price if you just want to get things sorted for longer term:

Unlimited minutes + Unlimited texts + 120GB data (5G) = £12 a month (24‑month contract)

They're a great set of deals that give you big-name reliability, without the big-name price tag.

Details and benefits
You won't find the 120GB SIM advertised directly
The first thing to understand is that the 120GB SIM only deal on this page is an exclusive hidden offer that Three have shared with us, to pass on to our readers.
To get 120GB on the regular part of their website, you'd currently be looking at paying £18 a month. So this deal saves you £6 a month. That adds up to £72 off per year.
To get the deal, all you have to do is follow any of the links (like this one) on this page to it, and you'll be taken to Three's regular official website, with the 120GB priced at the lower £12.
The reason they do this is so they can offer thrifty deal hunters (like you!) lower prices via comparison websites, without lowering prices for everyone coming to their website.

Three are worth joining at full price anyway
We've been massively impressed in recent years with how Three have been investing in improving their mobile network across the UK. They've pumped billions of pounds in and it's paying dividends.
Their 5G data is UK leading for speed. We'd say Three are the only network getting near the true benefits of 5G, with peak speeds over 600 Mbps and typical downloads over 200 Mbps.
But they've not forgotten the rest of their network either. They've gone on a massive upgrade programme to switch 3G masts to 4G masts, meaning better coverage than ever, even outside built-up areas.
You've also got great extra features like WiFi calling, 4G calling, call forwarding, free hotspots on the Underground. There's no shortage of ways to stay connected on Three.
