Who Three 5G home broadband suits
Three 5G home broadband suits people who want broadband without a landline or an engineer visit, if they live in Three 5G coverage. It uses a mobile network instead of a cable, so there is no line to install. It is plug and play.
Your speed depends on the mobile signal at your address, so check your coverage before you sign. Our table lists two packages with an advertised speed of 150Mb and unlimited data. The speed you get also depends on your router and your Wi-Fi.
It suits homes that use a lot of data and do not need a fixed line. Contracts run for 12 or 24 months, and Three offers a 30-day money-back guarantee. If you need a wired connection, compare Sky, BT and Virgin Media before you decide.
Network, speeds and availability
Three 5G home broadband sends your internet over the Three mobile network, so you need no cable, no engineer visit and no landline. The 150Mb in our table is the speed Three advertises. Your own speed depends on the signal where you live, your router and your Wi-Fi.
A 5G signal can be strong at one address and weaker at another, so your speed may differ from the table. Treat the table speeds as a guide, not a promise for your home.
Availability depends on your address. Deals are for new customers in Three 5G coverage, so check your postcode on Three's website before you choose. Then sort our table by speed, or see our cheapest broadband page. Every table shows the date its prices were last checked.
What it really costs
Three broadband comes on 12-month or 24-month contracts. The total you pay depends on the monthly price, any rises and any fees.
Three states its mid-contract price rises in pounds on its deal page. Our table adds every stated rise, plus any setup or delivery fee, into the real cost. It also takes off the cash value of any bill credit, so you see what you actually pay.
Three includes unlimited data and a 30-day money-back guarantee. It also lists up to £300 credit when you switch. Any credit like this lowers the real cost in our table.
Sort the table by real cost, cheapest first. Then compare it with rival deals on cheapest broadband before you decide.
