When Can I Upgrade on Three?

You can upgrade on Three free of charge 38 days before your minimum term ends. If you're still unsure when your upgrade is due don't worry we can help with that. Our team can check this date, and advise you on timings to see if you're eligible. If you are indeed eligible we can assist you on the journey of finding the perfect three upgrade deal for you.

If you're slightly before 38 days of your minimum term contract and you don't want to wait, there's an upgrade option for you too - this however would consist of an early upgrade fee. 

If you need help placing your Three upgrade order give us a call on 033 900 1133, our UK-based call centre will be happy to help.
