A Mumsnetter's guide to O2

My old phone is broken and I need a replacement ASAP! How long will delivery from O2 take?

You can Click & Collect from your local O2 store, and depending on stock it could be available instantly, or it will be available once ordered in. Home delivery is free and if you order by midnight your phone should arrive by the next working day, or you can select a more convenient day.

I’d like to have a browse at the phones in store before I make any decisions, where can I find my nearest O2 shop?

Use the store locator to see where your closest O2 shop is. You can also visit an O2 Guru if you need help with anything, or book your phone in for a repair at selected stores.

I want to switch to O2 from my current phone network but need to keep hold of my phone number, is this possible?

You’re able to keep your old number when you switch by requesting your PAC number from your current provider then quoting this to O2. You’ll need to fill in a form with the temporary number you’ve been given while the switch takes place along with your old number. O2 will have your old number back in use within 2 working days.

Before I choose O2 I want to make sure I can get phone signal in my area so I can be reachable whenever my kids need to call me. Can I check coverage?

You can see whether your area receives strong signal from O2 by using its coverage checker.

I’m not using my phone much so have decided I want to switch to pay-as-you-go. Can I cancel my contract with O2?

Contracts with O2 last for 12, 18 or 24 months, so if you want to cancel before these periods end you will need to give O2 30 days notice and you may be charged a fee.
