Getting in touch with Three

Getting in touch with Three

Three is one of the UK’s main mobile providers, being part of the ‘big four’ networks that make up the nation's mobile network coverage (along with EE, O2 and Vodafone). They also don’t just offer mobile services, but also mobile broadband and services for businesses.

AI chatbots and FAQ’s are typically the way providers like to push current and potential customers if they have any queries. But sometimes, they’re not enough. 

Some problems, issues or questions can’t be answered or solved without real human help, so that’s why being able to get in touch is still vitally important.

The problem then, though, is that many of these providers have several numbers to choose from depending on what you need, which doesn’t make things easy.

It can be made easier, and that’s where this Three contact number guide comes in, as it provides the numbers you need for broadband, mobile and business customers.

How do I speak to Three customer service?

If there’s one thing Three does very well, its that they make it easy for their customers, future or current, to contact their customer service team. They do this by offering the one number to call depending on which customer you are.

Their customer service number will have various options for you to choose from to be able to direct you to the specific help you need, so you’ll find that all the following sections may feature the same number.

We’ll start with personal mobile customers customers first, and for existing customers, the number to call is 333.
