Is the lowest monthly price the best deal?
In this case the lowest monthly deal is also the cheapest overall, but always check the upfront cost and the 24-month total.
What will April price rises add?
On the cheapest O2 deal, about £60 over 24 months for a contract started this month. The table below adds the rise for every network.
Should I buy it outright instead?
We don’t have a SIM-free price for this phone right now, so the contract is the only route we can price.

Galaxy S24 Ultra on every network
The cheapest 24-month deal on each network, sorted by the true total — the headline total plus the April rises the network has announced.
| Network | Monthly | Upfront | 24-month total | April rises (est.) | True total | |
|---|---|---|---|---|---|---|
| £29 | £129 | £885 | +£60 | £885 | View |
 | £30 | £129 | £909 | +£60 | £909 | View |
 | £37 | £29 | £972.20 | +£55.20 | £972.20 | View |
Rises use each network’s announced amount in pounds (Tesco Mobile about 6%). Sky Mobile’s rise isn’t fixed in the contract, so it isn’t included.
Our take on the Galaxy S24 Ultra
The cheapest way to get the Galaxy S24 Ultra on contract today is on O2: £129 upfront and £29 a month with 200GB of data, £885 over 24 months. At the other end of our table, Three’s best deal works out £87.20 dearer once rises are counted — the same phone, so the network choice alone is worth that much.
O2 adds £2.50 a month every April, so a contract started now costs about £60 more than the headline figure: £885 in all. Networks without an annual rise are worth a look if the gap is small.
The Galaxy S24 Ultra has a 6.8-inch screen, a 5,000 mAh battery, a weight of 232 g. It is on sale with 256GB of storage in 1 colour. It was released in January 2024.
