4G broadband for areas without fibre - plug and play setup
If your postcode lacks full-fibre broadband, Three's 4G hub offers an alternative that works anywhere with a decent mobile signal. The device arrives pre-configured, so you simply insert the SIM, plug it in, and connect via Wi-Fi. A 14-day returns window lets you test real-world speeds before committing.
Three app - manage your plan and track data usage
Download the Three app for free to view your remaining data, pay bills, add add-ons, and upgrade your handset without calling customer service. The app also shows personalised upgrade eligibility dates and any current promotions tied to your account. Available on iOS and Android with no subscription required.
Samsung Galaxy contracts with trade-in discount
Pair a Samsung Galaxy handset contract with a trade-in of any qualifying smartphone to lower the upfront cost or reduce monthly payments. The Galaxy S and A series are both available, with the newest models offering the largest trade-in valuations. Existing Three customers upgrading early may need to pay off remaining device plan balances first.
iPhone deals on 24-month contracts with 5G included
The latest iPhone range is available on Three with a range of upfront costs and monthly airtime plans. Higher upfront payments reduce the monthly fee, and all contracts include 5G access at no additional charge. Personal hotspot is included as standard, letting you share your connection with other devices.
Save with multiple SIMs on one Three account
Add extra SIM-only lines to an existing Three account and each additional plan comes at a discounted monthly rate compared to buying separately. All lines share a single bill and can be managed through the Three app. This works for family members or anyone who wants a second number, and each SIM keeps its own data allowance.
Pay As You Go bundles from £10 with data rollover
Top up £10 or more and convert your credit into a 30-day Pay As You Go bundle that includes data, minutes, and texts. Unused data rolls over to the next month as long as you renew before the bundle expires. No credit check is required and there is no ongoing contract, so you can change or cancel your bundle at any time.
Refurbished phones at reduced prices with warranty
Three's refurbished range includes returned and reconditioned handsets that have been tested, cleaned, and repackaged. Each device comes with a minimum 12-month warranty and a battery health guarantee. Grades range from pristine to good condition, with the lower grades offering bigger price reductions on the same models.
Unlimited data SIM plans with no speed throttling
Choose a truly unlimited data SIM with no monthly cap and no traffic management on standard usage. These plans support tethering and personal hotspot use, though Three's acceptable use policy applies if you exceed 1,000GB in a billing cycle. Available as 1-month, 12-month, or 24-month contracts with 5G included throughout the UK.
Switch to Three and keep your number with a PAC code
Text PAC to 65075 from your current SIM to get a Porting Authorisation Code within 60 seconds. Enter this code during checkout at Three and your old number transfers automatically, usually within one working day. Your previous contract must be active when you request the code, and any outstanding device payments with your old network remain your responsibility.
Trade in your old phone for credit towards a new device
Send your current handset to Three and receive a valuation credit that reduces the monthly cost of a new phone contract or the upfront price of a SIM-free device. The trade-in value depends on the model, age, and condition of your phone. Devices with cracked screens still qualify but receive a lower valuation. You will get a prepaid envelope to return the phone after your new order is confirmed.
5G Home Broadband with no landline required
Three's 5G home broadband plugs into a standard wall socket and broadcasts Wi-Fi using the mobile network, so there is no need for a phone line or engineer installation. Plans include unlimited data and are available on rolling monthly or 24-month terms. Speeds vary by location, so check the coverage map before ordering.
SIM Only plans from £8 per month with no upfront cost
Monthly SIM-only contracts start at £8 for a basic data allowance and go up from there. All plans run on Three's 5G network at no extra charge, and you can keep your existing number by requesting a PAC code from your current provider. Shorter 1-month rolling contracts are available alongside 12 and 24-month commitments.
