Three deals: Get a MASSIVE 50% off this cheap SIM-only plan

As Three deals go, this is terrific: a gigantic 50% off the price of its 30GB SIM-only plan for the first six months, making it just £7/mth

Three deals are well-known for delivering huge discounts on data, but this offer stands apart: for a limited time, you can get a jaw-dropping 50% off the price of 30GB of SIM-only 5G data for the first six months of a two-year contract. That means you'll be paying just £7/mth, leading to an overall saving of £42 before the price rises to £14/mth for the remainder of the plan. It's a blockbuster bargain, especially if you want to cut costs in these difficult financial times.

To put it in perspective, you'd have to pay £14/mth for a mere 1GB of data from EE, £15/mth for just 5GB from Vodafone and £15/mth for 30GB with Sky. You'll also be able to take advantage of Three's 5G network, which is both the fastest and widest in the UK, according to Opensignal's most recent tests

In short, this is one of the most cost-effective Three deals around at the moment, offering you more than enough data for a month of heavy browsing, streaming and gaming. Just make sure you sign up as soon as possible because it won't be around for long.

In our latest review of Three's service, we were impressed by its value for money and expanding 5G network, which Opensignal found to be the widest in the country. It delivers blisteringly quick average 5G download speeds, posting 204Mbits/sec and leaving second-place EE in the dust. Our major quibble is Three's comparatively so-so customer support scores, but most users were still satisfied with their service in our Mobile Network Awards survey.

But the Three deals haven't finished yet. If you're after a bigger plan, you can currently get unlimited 5G data for just £11/mth for the first six months of a two-year contract (then £22/mth for the remaining 18 months). To sweeten the deal, Three is also throwing in a whopping £100 prepaid Mastercard if you're switching to the network. The company offers an eye-catching 100GB for £16/mth plan too.

The 30GB for £7/mth for half a year is still our pick of the Three deals, though, offering a decent amount of data for a budget-friendly price. Once again, get in there quickly to avoid disappointment.
