Here's everything you need to know about our exclusive Three Value plan, which comes with 30GB data on a 12-month contract. Last updated: 14th September 2026

Is Three’s exclusive 30GB for £7 Value plan any good?

It’s a huge discount vs what you’d normally pay

On the main part of Three’s website, the closest Value plan you can get to this is 25GB for £21 a month. Use this hidden offer instead and you’ll pay just £7 for 30GB on a 12-month contract.

That is a ridiculous £14 monthly saving: £168 over the 12 months. You are paying one-third of Three’s usual price without dropping down to one of their stripped-back Lite plans.

This is a hidden exclusive offer. Using our offer link on this page takes you straight to Three’s website, where you order direct from the network and become their customer in the normal way.

It is also the cheapest 12-month deal in our comparison with at least 30GB and inclusive EU roaming from one of the four main UK networks:

Value means you get EU roaming that you don’t get on Lite

Most of Three’s cheapest tariffs are Lite plans, which make you pay extra to use your normal allowances abroad. This one is from their Value range, which include roaming in 49 European destinations.

You can use your unlimited minutes and texts while you’re away, including calls to standard local numbers. Three let you take up to 12GB from your monthly data allowance, which should be enough for a week or two.

And you get all the basis you’d expect too: unlimited UK calls and texts, 5G access, WiFi calling, tethering, eSIM support and Three+ rewards.

Ofcom’s latest figures put average monthly mobile data use at 10.6GB. 30GB would cover around a day of continuous YouTube viewing in 720p HD. So this deal is for frequent users but not people who know they want to totally rinse their data.

Three’s network is more reliable than ever for 5G

✔ Access Vodafone’s network tooWhat this means

Three are an excellent network for putting your 30GB data to work. Independent tests consistently put their typical 5G speeds ahead of the other UK networks, while 4G performance has improved considerably too.

In lots of areas too, you will be able to access the Vodafone network as well as Three. This is because the two companies have merged and are in the process of combining their networks. Check their network map here.

But it is worth noting that this deal comes with a 100 Mbps speed cap. Most of the time, you may not reach that anyway. But if you’re after bragging rights, then in superfast 5G locations, you will be held back.

In an ideal world, there would be no speed caps but for £7 a month, it is one of the few trade-offs of this deal. It is one of the easiest Three deals we’ve had to recommend.
