What are O2's secret offers?
Get better value deals directly from O2
✔ Take your plan from O2 directly
You may be looking to join O2 but are a bit put off by their generally high plan prices. In that case you’ll want to consider their better value hidden deals they share exclusively with comparison websites like us.
These usually give you a lower price or more data for the same price as their regular range. But they often have some unique offers altogether. And you won’t find these advertised anywhere on their website.
The other benefit of these special offers is that you’re not signing up via some third party reseller that you won’t be sure you can trust. You join O2 directly just like you would on any of their other contracts.
O2 won’t keep the special offers below around forever. They often chop and change these and sometimes won’t have any. We’ll update this page when they do, but if you see one you like now it may be best to go for it.
