What should you know before choosing Three?

Three offers mobile phone contracts, SIM-only plans, mobile broadband and 5G Home Broadband. Its Home Broadband service uses the mobile network rather than a fixed landline, so there is no need for a phone line or engineer installation.

It is worth checking the full contract price rather than just the starting monthly cost. Three applies fixed annual price increases to many current plans, with the amount depending on the type of plan and data allowance. How can you save money with Three?

Founder insight: lowering the cost of staying connected

Reliable internet is an essential life line - especially for disabled households managing appointments, prescriptions, and daily support networks. However, many disabled individuals miss out on social tariffs because non-means-tested benefits like PIP aren't always accepted. At Purpl, we're dedicated to helping bridge that gap so no one pays more than they have to for essential digital access.

What is the Three returns policy?

Phones, tablets and broadband devices bought online can generally be returned or exchanged within 14 days, provided the device is kept in an “as new” condition.

Three gives Home Broadband customers 30 days to return the hub and cancel the Home Broadband service.

Three advises customers returning a device to contact its Returns Team rather than sending equipment to an address provided by an unsolicited caller, as return-address fraud can occur. Why is Three working with Purpl?
