Frequently Asked Questions

Upgrading Your O2 Service?

Upgrades on O2 are a bit different to the other mobile networks, as you are able to upgrade early for a fee if you subscribe to their O2 Refresh plan. This lets you get a new device whenever you like, but you may have to be a small charge.

You can check if you are due an upgrade by giving the O2 contact team a call on the telephone number at the top of the page.

You can typically upgrade to a new phone if you have finished your device plan or if you are at the end of your contract.

How Good is the O2 Network?

The O2 network has one of the strongest networks in the UK and provides the infrastructure to operate brands such as Tesco and Giffgaff.

Giffgaff is partly owned by O2, and is a Pay as you Go provider that now offers some SIM only contracts and phones.
