How to buy

If you’d like to join Three Business, chat to us online or call us free on 0808 258 0333, and we’ll talk you through the process. It involves giving us company information, ID, and going through a credit check.

If you have an online business account, you can add 10 lines per day in one transaction. So for example, you could add 30 lines over the course of 3 days. If you don’t have an online account, or want to add more than 10 lines in one transaction, chat to us, call us on 337 from your Three Business phone, or visit a Three store.

Not at the moment. But we fully understand the importance of offering an online service to all our Three Business customers. Our team is working on ways to transfer existing customers to the new system, and we’ll keep you updated.

Our aim is to help every customer get the best deal possible by matching their business needs with our offers. If you have any questions on pricing, please chat to us online or call us free on 0808 258 0333, and we’ll talk you through all your options.
