There are some great deals for the Apple iPhone X on EE, Vodafone, O2 and Three - in two colours, space grey and silver.
It marked the pinnacle of iPhone's 10 year history, but has now been surpassed by the iPhone XS and XS Max
The phone was Apple's starting place for the new buttonless design, although it has since been updated with the launch XS series, but it still very much holds its own.

Price is obviously a key factor and while you can lower the monthly cost of the contract by paying a higher upfront cost, most will prefer to spread the cost over the course of the contract period.
