Pay Monthly
A Pay Monthly contract spreads your new phone's cost over 24 or 36 months alongside your airtime plan. Here is exactly how it works — including the parts networks don't always highlight.
A Pay Monthly phone contract bundles a new handset with a monthly airtime plan — calls, texts, and data — into a single monthly payment. The smartphone's retail price is divided across the contract term (24 or 36 months) and added to your monthly airtime cost. You receive a brand-new phone without any large upfront payment, at the cost of a higher monthly bill for the full contract period. When the contract ends, the phone is fully yours at no further cost.
Modern UK networks increasingly separate the phone cost from the airtime cost on your bill — even when you pay a single monthly amount. O2's Refresh model and similar approaches from EE show you exactly how much you are paying for the handset versus the service. This transparency is important for two reasons. First, you can see exactly when your phone will be fully paid off. Second, it reveals the most common and expensive mistake in UK mobile: when your contract ends, the device plan is complete but the airtime plan continues — and many networks continue charging you the combined amount until you actively renegotiate or leave. Moving to a SIM Only airtime plan at contract end typically saves £10–£20/month.
Because a phone contract effectively finances the cost of a handset, UK networks perform a credit check before approving applications. A soft eligibility check typically does not affect your credit score. The hard search performed when you formally apply does appear on your credit file. A poor or limited credit history may result in a declined application or a requirement for a higher upfront cost. If you have been declined, PAYG plans and many MVNO SIM Only plans require no credit check at all. Building your credit history and reapplying in 6–12 months is often the most straightforward path to phone contract approval.
24-month contracts are the most common and typically offer the best balance of lower monthly price and reasonable commitment period. 36-month contracts spread the handset cost further and reduce the monthly payment, but lock you in for three years — a long time in smartphone development. 12-month phone contracts are available from some networks at a significantly higher monthly cost but with faster upgrade eligibility. Always calculate the total cost over the full contract term (monthly price × number of months, including post-rise months) rather than just the headline monthly figure. A £30/month 24-month plan that rises by £1.50/month in month 13 totals £714, not £720 at face value — but a competing plan at £32/month that doesn't rise totals £768. The comparison is not always obvious.
Networks typically allow upgrades from around the halfway point of a contract, usually by settling the remaining device plan balance or rolling it into the new agreement. O2 Upgrade, EE Flex, and Tesco's Anytime Upgrade Flex all provide structured early upgrade paths. Always calculate the total cost of an early upgrade — including any settlement fee and the new contract's total cost — against waiting until contract end. Early upgrades are convenient but rarely the cheapest option.
If you need a new phone and cannot or prefer not to pay £800–£1,200 upfront, a Pay Monthly contract is a practical route. But over the full contract term, buying a phone outright (or refurbished) and running SIM Only is almost always cheaper in total. The argument for Pay Monthly is purely about cash flow — spreading a large upfront cost — not about saving money overall. Before signing a Pay Monthly contract, calculate the total contract cost (monthly × months) versus the phone's current outright price plus the equivalent SIM Only plan's total cost over the same period. The honest comparison usually shows a gap of £50–£200 in favour of the outright-buy route.
