Compare the best iPhone 5S deals here to find the perfect contract deal

The plucky iPhone 5S is still going, even though it's now been replaced by the iPhone SE and there's even the iPhone 7 to contend with. But if you're looking to upgrade your phone for the new year, there's never been a better time to pick up the iPhone 5S.

Apple may not be producing the 5S anymore, there's plenty of stock still sitting around in network's store rooms. They want to shift the stock, so there are some amazing deals to be had. 

Choose from 16GB and 32GB versions, and you'll find the 5S is still a great little handset. We've found the best deals currently on the market just for you.
