What are Bolt Ons?
When you're running low on minutes, texts or data, you can top up with a Bolt On, from as little as £3 a month. There are even Bolt Ons for calling abroad, or if you're going away yourself.
If you're already with O2, you can manage your Bolt Ons in My O2. Otherwise you can add them once you've joined us.
If you have a Spend Cap, the price of these Bolt Ons will not be included within your Spend Cap.
