Simple Ways to Save at Three
Saving money on your phone bill or a new device doesn't have to be complicated. Here are the easiest places to start:
- Check for Student Discounts: If you're a student, Three offers a significant discount on monthly plans. You just need to verify your student status online.
- Look at SIM-Only Deals: If you're happy with your current phone, switching to a SIM-only plan is one of the biggest money-savers. These plans are much cheaper than contracts that include a new handset.
- Use a Price Promise: Three offers a price promise on certain plans, guaranteeing your monthly price won't go up for the length of your contract. This protects you from surprise bill increases.
- Always Search for a Voucher Code: Before you complete any purchase on Three's website, check our coupon site for the latest promo codes. You can often find discounts on accessories, plans, or even upfront device costs.
Best Times to Shop
While Three has offers year-round, you can time your purchase to catch the biggest savings.
- Seasonal Sales: Like most retailers, Three has major sales
