How to Compare O2 Phone Deals on Switch
Find the right O2 contract in under two minutes
1Step
Search by Phone Model
Type the phone you want — iPhone 17, Galaxy S26, Pixel 10 — or browse all O2 handsets. Switch shows the O2 deals listed on this page, sorted by monthly cost ascending.
2Step
Set Your Filters
Filter by monthly budget, data allowance (from 1GB to unlimited), and contract length (12, 24 or 36 months). O2 Refresh plans are flagged separately, look for these if you want flexibility to upgrade early.
3Step
Compare Full Costs
Switch shows the total contract cost alongside the monthly rate, including upfront costs. A deal with no upfront cost often has a higher monthly rate; knowing the total helps you pick the better value deal over the full term.
4Step
Click Through and Order
Every link goes directly to O2 at the exact price shown, no hidden fees, no Switch mark-up. Prices are updated daily from the network's own listings.

Looking for the right O2 deal?
O2 handsets are sold across every UK network and several refurbished retailers, and the cheapest deal in the table above is rarely the one with the most expensive headline price. Filter by total cost (handset + 24 months of contract) to spot real value.
If you don't need the latest model, the Refurbished filter unlocks like-new handsets one or two generations old at 20–40% off, they come with a 12-month warranty either way.
