How are price rises calculated?
Some providers set annual price rises to cover predicted changes in service costs. This is usually linked to inflation, but from January 2025 they have to tell you the exact amount upfront.
In our breakdown, we've assumed your first bill will be next month, and your billing date falls after the date any price rises come into place.
Why choose O2 Mobile?
- Priority tickets and Priority offers
- Tariff flexibility with O2 Refresh
- Free EU roaming up to 25GB

Frequently asked questions
A SIM-only deal gives you a SIM card on a 1-month rolling plan or a 12/24-month contract — no phone included. It's usually cheaper than a phone-and-airtime contract and lets you keep using your current handset.
