More about Three

Using the Three App 

The Three app allows customers to manage their data, contact customer support, log onto their My3 account, and access exclusive Three UK deals on extra data, calls, and handset upgrades.

It's an essential tool for anyone who struggles to keep track of mobile bills, as well as pay-as-you-go customers who need to know how much credit they have remaining.

Three Network Review 

Three Mobile is the fourth largest mobile phone network in the UK, and it tends to do quite well in company comparisons.

Commentators often [h]highlight[h] affordable Three phone deals, the wide range of phone models on offer, unlimited data plans ("All You Can Eat"), and strong customer support.

Three Contact Information

If customers want to get in touch with Three regarding their contract, upgrades, or how to use Three vouchers, doing so should be fairly simple. Current customers can just call 333 to access 24/7 support.

Otherwise, they can call: 0333 338 1001 (8:00-20:00 Monday to Friday, 9:00-18:00 at weekends). Online support is also available via My3 accounts.
