Best Samsung Galaxy S21 preorder deals: Pick the right contract for you

Compare preorder contracts for the Samsung Galaxy S21 from the UK’s top networks, including EE, Three and O2

Preorders are currently open for the Samsung Galaxy S21, Galaxy S21 Plus and Galaxy S21 Ultra, ahead of a planned shipping date of 29 January. That means every mobile provider worth its salt is readying to stock and sell Samsung’s latest flagship.

With a variety of monthly contracts scattered across a number of providers, it can be difficult to get a sense of how one deal compares with another. To help, we’ve scoured the UK’s top providers to see how they measure up. In each case, we’ve picked a low-tier, mid-tier and top-tier data plan for a rough guide to the cost you’ll face.

These are just the surface-level figures, so if something grabs your eye, be sure to check the official site for more details about the contract, internet speeds and other important information. We’ve also included any pre-order bonuses where we’ve seen them, such as ‘free’ hardware and gaming bundles, although similarly you’ll also want to check the small print from the networks themselves as not all contracts come with the same benefits.

We’ve focused below on monthly contracts, but if you instead want to buy the Galaxy S21 outright, you can do that via Samsung directly for the below prices. Samsung will also throw in  either a pair of its Buds Pro or Buds Live earbuds, as well as a free Galaxy SmartTag.
