How To Contact O2

Whether you can get a new device at a reduced cost or for free depends on a few different things. If you are on a high-end contract that is nearing its expiry date then it is likely you can negotiate for a phone or receive a new handset when you renew your contract.

If your contract has a significant amount of time left you may need to pay additional costs or the cost of the remainder of your contract in order to sign up to a new plan and receive a new handset. If you are on Pay As You Go with O2 then you may need to purchase your handset outright.

For more information on plans available, you should contact O2 support directly.
