It depends on the network and the specific deal. Many major UK networks apply an annual price rise, typically in April. Where the live feed includes a rise amount, Smart Comparison shows it on the Samsung Galaxy S25 Ultra deal card. Check that disclosure before you choose a plan.
The monthly price on a Samsung Galaxy S25 Ultra contract usually covers the handset and the airtime plan. Compare the upfront cost and the total over the contract, not only the headline monthly price. Where a mid-contract rise applies, any total based on the current monthly rate excludes that later increase.
