The Three contact numbers you need for all your queries and questions.

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.

What is the Three customer service contact number?

As just mentioned, there is the three-digit number you can call from your Three phone that will take you to their customer service team. But if you’re not calling from a Three phone number, there is still a number you can call.

The customer service number for personal mobile customers is 0333 338 1001 from any number other than a Three phone.

Can you call Three 24 hours a day?

Three’s customer service is available from 8am to 8pm Monday to Friday, and 9am to 6pm on weekends.

24-hour customer service is a huge expense for any company, which is the reason why you won’t find many providers offering such a service.

What is the Three contact number for new customers?

If you’re interested in learning about Three’s products and looking to join the provider, you can call their customer service team who will be able to provide the relevant information for you.

The numbers to call remain the same as the ones in the Three customer service section, which is either 333 from a Three number and 0333 338 1001 from any other number.

What is the Three contact number to upgrade or add a product/service?

Three upgrades usually refer to mobile plans and can typically be done via the My3 app or in-store. However, if you are looking to speak to someone over the phone, the number to call is the same as the customer service number – 333 from a Three number and 0333 338 1001 from any other number.

If you are looking to add a new service or are looking to create an order by phone, you can call 0800 033 8006 and they will be able to process your order.

What is the Three contact number for technical support?

The technical support team is on hand to help you with any problems you may encounter as a personal mobile customer. This also applies to any account or billing issues.

Once again, the number to call is 333 from a Three number or 0333 338 1001 from any other number.

What is the Three contact number for reporting a lost or stolen device?

If you have had an experience where you unfortunately have lost your mobile phone or had it stolen, you can contact Three to find out your options on how to move forward.

Three recommend you contact them as soon as possible in these cases so that they can protect your account. If your phone has been stolen, your first step should be to contact the police and get a crime reference number.

Once you have that, you can contact Three’s customer service and head to the relevant service to sort out everything out.

What is the Three mobile broadband contact number?

Three offers mobile broadband, a great alternative option to standard broadband, where the broadband connection is provided via a 4G or 5G (depending on coverage). 

If you’re interested in finding out more about Three mobile broadband or are a current customer who needs to contact customer service, the numbers to call are 500 from your Three phone or 0333 338 1003 from any other number.

What is the Three business customer service number?

Three offers business plans for companies looking to offer employees mobile and/or SIM-only plans.

For business customers, the number is 337 from your Three business phone or 0333 338 1004 from any other number. 

You can also call to make an order using the number 0808 258 0333.

Three business help and support is available Monday to Friday, 8am to 8pm, and 9am to 5pm on Saturdays and bank holidays.

How do I make a Three call abroad?

If you are abroad and find yourself in need of Three customer support, then you’ll be happy to know that there are specific numbers for both personal mobile customers and mobile broadband customers to call.

• +44 7782 333 333 from abroad for personal mobile customers
• +44 7782 333 500 from abroad for mobile broadband customers

Unfortunately, there is no number to call from abroad for business customers.

Does Three charge for 0800 numbers?

All 0800, 0808 and 0500 calls are free with Three, while 0300 numbers come out of your minutes allowance.

How do I contact Three mobile to pay my bill?

You can pay your Three mobile airtime bill in multiple different ways, including by phone.
