Live chat

Three’s live chat service lets you speak to the network online by typing messages.

This service is available from 8am to 10pm Monday to Friday, and from 9am to 8pm Saturday and Sunday. It can be accessed here.

Local Three Store

If you’d rather contact your local Three store that’s an option too. There are over 300 of these across the UK, so there’s likely to be one near you.

Store staff can assist you with purchase decisions, support for devices or services you’ve already bought from Three, top-ups, or network and allowance queries. Some stores also offer Three Store Now, which allows you to connect with store staff online.

Exact services and opening times vary from store to store, but you can find all of those details, along with store addresses and phone numbers, in Three’s store directory.

Accessibility team

Three also offers several contact options for customers with accessibility needs. These are as follows:

Complaints

Three always tries to provide the best possible experience, whether you’re a new, existing or potential customer. However, if you haven’t been fully satisfied with Three’s service then the network would always want to hear about it so that it can put things right.

To file a complaint you can use Three’s complaints form, give the network a call, or use live chat. You can also file a complaint on behalf of somebody else – as long as Three gets confirmation of their consent. For full details of how to file a complaint, head here.

A suite of guides are available which may help answer the questions you have without needing to contact customer service.
