Three broadband: deals, speeds, and bundles

Mobile broadband providers like Three offer a level of flexibility that you wouldn’t get with standard fixed line broadband. It’s ideal if you need broadband somewhere that doesn’t have an Openreach connection, or if you only need internet temporarily. Three Home Broadband is available on a range of contract lengths, including rolling monthly and longer-term plans. The options available can vary by deal and coverage.

Three offers Home Broadband over its 4G and 5G mobile networks, so there’s no need for a fixed phone line or fibre connection to your property. Its 5G Home Broadband currently advertises average download speeds of 150Mbps, while actual speeds depend on coverage and local network conditions.

Setup is straightforward: the hub is delivered to your home and plugs into a power socket, with no engineer visit required.

Three also offers a 30-day money-back guarantee on eligible Home Broadband plans, giving you time to see how the connection performs at your address.

What are Three’s broadband bundles?

Three doesn’t offer traditional broadband bundles with a landline or TV service. Its Home Broadband is primarily a standalone internet service, although optional Wi-Fi equipment may be available.

Nevertheless, because Three is a mobile network, you can get your mobile phone or SIM from them - and pay for both your broadband and mobile in the same bill.

Is Three broadband-only?

Yes. Three Home Broadband is a broadband-only service and does not require you to take a landline or TV package.

There are two types of broadband available:

Home broadband: Delivered through a 4G or 5G hub, with rolling monthly and longer-term plans available. Simply plug in the router to get started.
Mobile broadband: Portable Wi-Fi using a 4G or 5G MiFi device, with monthly and longer-term plans available. Compatible devices can connect multiple devices and offer up to six hours of battery life.

There’s no need for a phone line or even an Openreach socket in your home, making it very handy if you require internet in a short-term property or on the go.

The speeds you can get with Three depend mainly on whether 4G or 5G Home Broadband is available at your address, along with local signal and network conditions.

5G – average download speeds of 150Mbps
4G – available in selected areas where 5G isn’t available. Speeds vary depending on local coverage, network demand and the position of your router.

For comparison, part-fibre broadband commonly offers tens of megabits per second, while full-fibre services can offer several hundred megabits per second or gigabit speeds.

Full-fibre broadband can offer gigabit speeds or faster, depending on the provider and availability at your address.

Who we compare

We compare broadband deals from providers who take part in our comparison service.

This means the results may not include every broadband provider in the UK, every package from each provider, or every deal available directly from a provider.

Before you apply, it is worth checking whether the deal meets your needs and whether any other offers are available elsewhere.

How deals are updated

Broadband deal information is provided to us through supplier feeds and provider data.

We refresh deal information regularly so that prices, speeds, offers and availability are kept as up to date as possible.

Deals can change or be withdrawn by providers, so you should always check the final price, offer details and provider terms before applying.

Why we ask for your address

Broadband availability can vary depending on where you live.

Your address or postcode helps us check which broadband deals are more likely to be available at your property. Availability can depend on things like network coverage, local infrastructure, line availability, property type and installation requirements.

The results are based on the information available at the time you search. Final availability is confirmed by the provider when you apply.

How average monthly cost is calculated

Average monthly cost is intended to help you compare deals more easily by showing the estimated monthly cost over the contract term.

It may include the monthly price, contract length, upfront or setup fees, discounts and selected rewards where these can be included in the calculation.

Some rewards or incentives may be shown separately and may depend on eligibility, redemption steps or provider terms.

The average monthly cost is a comparison figure. Your actual payments may differ, especially if prices change during the contract or if you add extras.

New customers only

Most deals shown are for new customers unless stated otherwise.

If you are already with a provider, you may not be eligible for the same deal. Existing customers may need to contact their current provider directly to discuss renewal, upgrade or retention offers.

How deals are ranked

Ranking may take account of factors such as availability, price, speed, contract length, features, rewards, special offers and commercial arrangements.

You may be able to change the sort order or filter results to focus on what matters most to you, such as price, speed or contract length.

Featured deals and sponsored placements

A “featured deal” is a deal that is highlighted in the comparison results.

Featured deals may be paid placements, sponsored promotions or deals that are commercially agreed with MoneySuperMarket.

A featured deal is not necessarily the cheapest deal or the best deal for every customer. You should compare the full deal details before applying.

Special offers

A “special offer” means a deal includes an incentive or promotion.

This could include things like a limited-time monthly price, voucher, cashback, bill credit, reward card, free setup, free installation or another benefit.

Special offers may have separate terms, eligibility rules, claim steps and end dates. You should check the provider’s terms before applying.
