Samsung S26 Ultra 1TB White on O2: Unlimited 5G, EU Roaming, £9 upfront + £41pm/24m

This S26 Ultra deal on O2 looks pretty solid. It comes with unlimited 5G data, minutes, and texts, so everything's covered. There's also the Volt benefit, which can boost broadband speed if that's relevant. Good to know it's a straightforward offer with just one code needed, and no trade-in is required to get it.
